The CHEAP and EASY way to add backboards to your backyard ice skating rink!


The CHEAP and EASY way to add backboards to your backyard ice skating rink!

So you want to add backboards to your skating rink.  Backboards are a great upgrade that is well worth the effort but you have to build them strong to support the high leverage loads of impact.  There are many expensive and extravagant ways to do this but I am going to focus on how to do this inexpensively, with minimal labor, and minimal materials.    
First, let’s assume you have a 2’ by lumber skating rink frame.

Step 1-Build your rink frame just as you always have.  No extra money required and no extra effort. 
Step 2-Go to the local building supply store and ask for 4’ by 8’ by ¾” plywood ripped to 2’ by 8’ strips.  Buy enough plywood to cover your entire back wall.  You will now have 2’ by 8’ by ¾” plywood boards ready to add on to the skating rink for backboards.
Step 3-Take your first board and lag bolt it to the existing frame about 2” below the top of the frame (see diagrams below).
Step 4-After all of the plywood is lagged to the skating rink frame.  Utilize the Iron Sleek Outriggers, Iron Sleek Ground Stakes and a support 2 by 4 to give it the needed strength to withstand big slap shots and impact.  (See diagrams below)  If you use our Outrigger kit and Ground Stakes, Iron Sleek will provide you the lag bolts required to put up your backboard upgrades at no cost...FREE LAG BOLTS!! 
 
Some other notes:
For those who want full sheet backboards, use the same principals explained and diagramed in this blog but increase the size of the 2 by 4’s to 72”.

What should I use as RINK BOARDS for my Backyard Skating Rink??


What should I use as RINK BOARDS for my Backyard Skating Rink??
The beauty of smooth shiny ice under the clear evening moonlight and the crisp sound of skates cutting ice with the playful laughter of children and the aroma of fresh burning logs in the background air are definitely impressions that stick when we think of our backyard rinks…truly EPIC!!

All this is possible because a containment holds water in place allowing it to transform to the expanding miraculous ice when the ambient sinks below 32 degrees.  The containment has a great function but it also adds character and personality to an outdoor rink.  There are many materials that are commonly used to contain water to form an outdoor rink.  Some options for rink boards are:  dashers boards, 2” by lumber, plywood, commercial plastic, and snow banks.  These are all good options but it is up to the rink designer to choose between cost, effort, aesthetics, and their overall vision for the rink.  The chart and dialog below is a good starting point to understand some of the differences between the various options.


Let’s start with the most deluxe…Dasher Boards. 

Real hockey dashers are rigid metal frames, 48” tall, with ½” poly permanently attached to the frames that can sustain rough hockey play.  Dasher boards are usually permanently mounted, heavy, and require construction professionals for installation.  They are usually well decorated with a base trim and a colored top ledge.  There are companies in Canada and the US who have mastered this mainly commercial market.  Heavy duty, metal framed dashers with ½” poly boards cost over $100.00 per linear foot.  There are custom wood frame options starting at $60 per linear foot or aluminum frame options that start at $30 per linear foot.  Iron Sleek does not provide dashers but we would be happy to discuss other cost effective board solutions for you that could make your rink board look and play like dashers.

“2 by” lumber
“2 by” lumber is a great choice for building a skating rink.  2 by 12’s or 2 by 10’s are readily available in both Canada and the USA.  In Canada, 2 by 10’s are best the value.  Contrarily, in the US, 2 by 12’s are more favorably priced.  There are many benefits for using 2 by 12 lumber for rink boards.  2 by 12’s come in a wide range of lengths so our customers can build a rink without a single cut.  Also, 2 by lumber comes in very long lengths.  Our local lumberyard even has 20 footers.  With 20 foot boards, Iron Sleek’s 20 by 20 rink kit could be built with just 4 boards…No Seams!  Just as an FYI, most of our customers who use 2 by 12’s buy them in 10 foot length as they fit just perfectly in a minivan.  Some other benefits are that 2 by lumber is durable, easily stacked to build a 2nd story with the Iron Sleek extension bracket, and is the most cost effective solution for building a basic rink enclosure.  2 by lumber is also a tough construction material as it is strong enough so fewer Iron Sleek brackets could be spanned across the boards.  Another benefit of “2 by” lumber is that it is milled with a radius edge which helps prevent liner cuts where plywood has a sharper splintery edges.  Some short comings on using lumber for an outdoor rink is that that lumber is heavy and sometimes boards can warp if not stored properly.  Iron Sleek base cove works out great for to fill the gaps on warped boards.  Some other challenges with 2 by lumber is that the boards are heavy, they can split along the grains, and they can warp with time.  All in all, for about $1.25-1.50 per foot investment, 2 by lumber is a great inexpensive solution for building a skating rink.  Some tips on using lumber:


·       Try telling your lumberyard that you are building a backyard rink and that you would be willing to take boards with knots for a discount.  You may be pleasantly surprised.  When I built my first rink, I got 50% off for taking “inferior boards.”  The store clerk will be impressed that you are doing something so awesome and a few knots in a board will not affect the quality of your rink.  I still use those same boards today that I bought a decade ago.

 
·       Be careful to not miscalculate lumber sizes.  “2 by” lumber is just a nominal size.  The actual thickness of the lumber is only 1 ½”.  The same is true for the height.  For example, a 2” by 12” is acutally  1 ½” by 11”.    


·       Treated lumber is not necessary unless you plan on leaving your rink set up out in the elements year round.  Treated lumber costs more and is much heavier.  Since the liner will protect the boards during the rink season, treated lumber is not required.

 

·       “2 by” lumber is a great choice for building a free skating rink on a low pitched site.  The rink will go up easily and it is easier to maintain as snow could simply be pushed off the sides. 

Check out just how nice a 2" by 12 rink frame can look below:




¾” Plywood for Rink Boards
¾ plywood is also widely used as rink boards.  Did you know that in the old days plywood was used to build above ground pools?  Plywood is tough, durable, and readily available.  Plywood could be picked up almost at home improvement store.  Iron Sleek board wrap could help transform a plywood rink to a dasher aesthetic rink.  See below:

STEP 1
 

STEP 3--PLYWOOD TRANSFORMED

Plywood has several benefits for building a backyard rink.  Some of these are listed below:
 ·       Plywood boards can be ripped to accommodate water levels where 2 by lumber must be stacked. 
·       Plywood can be framed and painted to look and feel like real dashers. 
 
·       Plywood boards store easier since they are actually half the thickness of 2 by lumber.
·       Plywood is better for building a hockey rink.
·       Plywood is the choice of simplicity for commercial installers as they can stack and transport more boards to the job site.
 
Materials store can cut the lumber
Some of the challenges with plywood are:
·       Plywood sheets must be ripped.  I recommend asking your lumber provider to rip the plywood or you will be stuck with a time consuming tedious job of sawing.  Sometime lumber yards rip plywood at no cost.  In Chicago, Home Depot will rip up to 10 boards at no cost. 

·       You will need base cove to protect the liner because the edges are sharp and could cut the liner from below.  Cove is critical with plywood especially when water levels exceed 11 inches. 

·       Plywood flexes so the board will not appear straight even though they are installed straight.  The water pressure and ice expansion will show board flex throughout your rink season. 

·       Screws do not bite in as well in plywood as they do with 2 by lumber.  You must be especially careful to not strip out your screws when using a power drill. 

·    Plywood does not last as long as lumber if not stored or protected properly outdoors.

Snow banks as a rink boarder
 
I built my first rink 20 years ago with snow banks.  20 years ago, I quickly learned that snow banks are not a reliable way to contain an ice rink using the liner method.  The main reason is that the snow will melt on a mild day and your rink will soon wash away.  Also, when you are filling your rink, the snow bank will start to melt from the warmer water.  Yes, snow is free, but if you are serious about having a backyard family rink, choose a construction material as a rink board.  Snow banks are exhausting to maintain; however, they are still commonly used on ponds as it is difficult to bring construction materials to the edge of a lake.  Iron Sleek has simplified building a rink on a pond and has provide an alternative to snow banks with the Iron Sleek Pond Bracket.   See video below:

Can I build a rink over my in-ground pool?


Can I build a rink over my in-ground pool?



It would be amazing to transform a swimming pool area into a winter skating arena.  The pool area of a home is ideal for entertaining.  Power and lighting are in place and, in some pool areas, Jacuzzi’s and fire pits are already being used during the winter months.  How cool would it be to now have a winter ice rink for hockey and skating in the very spot where you swim and sunbathe in the summer months?   A rink in the pool area is a great idea for having a family fun time during the winter but there are several things to consider before you commit to this possibility.

 
Can it be done?

The most favorable scenario for building a rink above the pool is when the in-ground pool is surrounded by healthy concrete.  Most in-ground pools have a nice patio surrounding so they are well suited for this project.  If your pool is surrounded by pavers, it likely can also be done but extra care will be required to spread the base load. 

 How is it done?

In essence, what you will be doing is building a shallow pool above a pool (rink over in-ground pool).  The in-ground pool should be covered and closed just as it would be for a regular end of season winter.  A stage with trusses spanning the entire width of the pool should rest on the patio and be slightly raised above the pool.  Raising the stage is critical as it spreads out the base load and helps to level the platform if needed.  THIS METHOD LEAVES YOUR POOL UNTOUCHED.  The platform should be level within 2 inches to keep the water load at a minimum.  Then, side walls are put up around the stage to form a rink enclosure.  Finally, a one piece ice rink liner will cover the entire enclosure.  Now with the rink filled, patiently wait for the freeze.  All the same rules to building a backyard rink apply once the stage and enclosure are built.  If you want to make the rink gorgeous, consider using rink topper, rink rounds, and board wrap.

The Stage/Platform

The stage should be engineered by an architect or engineer.  Do not just wing this and do not do it yourself!  It would be a DIY undertaking nightmare.  The architect should design a deck that could support the load of the lumber, ice, and multiple skaters while being solid enough to minimize ice cracks.  The balance here is to keep stage profile low while keeping engineering specs and material cost in check.  If the stage is not solid, the bouncing will encourage the ice to shatter.  The dynamic and static load should be several times better than that of you own home.  Do not use basic 2 by lumber for truss as they are not stiff enough, use engineered trusses.  The truss manufacturers should be able to help your contractor determine the truss size and spacing for the application.  For the stage platform floor, it is recommended to use ¾ plywood with a tongue and groove.  Be sure that the stage base is well distributed along the concrete patio.  Also, be sure the stage is built in a way that makes it easy to disassembly.  When the stage is torn down for the season, dispose or recycle the liner and store the stage material indoors.

The Cost and the Effort

This is just a guideline from our experience in building rinks above pools in Chicagoland.  Building materials are $5.00 per square foot.  Labor comes out to $2.50 per square foot.  So for a 25 by 50 rink the cost would be $6,250.00 in materials and $3,120 in labor.  The labor effort is 4 skilled carpenters for nearly 2 days to assemble and just 1 day to disassemble.  Storage would cost about $1000/yr.  It seems like a lot of money up front but it is just a fractional investment compared to the pool while it repurposes your awesome pool area for the winter.  The material investment is mainly a one-time investment and the reoccurring cost of set up should be less the 2nd year than it was the first year because all of the wood cuts and field decisions will have been already completed.  A rink above a pool is a great investment in family fun that transforms your pool area to a winter wonderland.

Ice quality

You will have better ice because the rink is above the pool as opposed to being on the warm pitched earth surface.  Here is how this works.  The pool cover will act as a vapor barrier and will keep the warmer water from underneath from heating the ice rink.  The rink will actually freeze from both the top surface and the bottom because the ambient cold air will attack the rink water from both above the rink and below it.  On a basic rink built on lawn, the earth actually warms the water.  Freezing water on a rink built on lawn is a tug of war between the earth’s warm ground surface trying to heat the water and the cold ambient air working to freeze it.  With a rink above a pool, this tug of war of freezing does not exist.  We have all seen the street signage “Watch for Ice under Bridge”.  That same concept applies…it is colder under the rink because it is shaded.  Another consideration for better ice is that the platform will be level.  A rink built on grass has to negotiate several inches of ground pitch.  The ground pitch causes temperature gradients in the ice that cause cracking.  With the rink above the pool, temperature gradients will be minimal and it will also be likely that the rink water will freeze 100% throughout.  Seldom does a typical backyard rink freeze 100% across.  Conclusion, ice quality is better on a rink above a pool.

Pristine ice above the Pool!! 


Who does this?

-A rink above a pool is a luxurious expensive solution for an ice rink.  This is an option for families that can afford the more elaborate solution.
-This is a solution for families whose yards space is taken up by the pool.
-If your yard is severely sloped and the only flat area you have is the pool area, you may want to price this out. 

-A good solution for those who do not want to disturb their landscaping. 

 
Opportunities

-A rink on a stage is usually level enough to convert to a refrigerated rink.  If you want to extend your skating season from Thanksgiving to St. Patrick’s day, consider installing refrigeration. Refrigeration for a 30 by 50 rink starts at 50k plus extras. 

-The stage can be used as a sports court so you can enjoy it for roller hockey, basketball, paddle, or pickleball before the winter season hits and it gets converted to a backyard hockey rink.    
-The stage is not a complete sunk cost.  It should have resale value to a local ice rink installer.  Refrigerated rink are often build on platforms.

Backyard Ice Rink Liners

Liner

When it comes to choosing a liner or tarp, be sure that the liner is pin hole free, seamless, and white.  A seamless pin hole free poly liner does not weep water.  For an ice rink, water leaks usually result in extra maintenance and mediocre ice.  Also, depending on the winter, a weeping tarp could cause damage to the lawn as water can flood grass roots or trick the dormant lawn to become active in the middle of winter.
White liners or tarps make a big difference for forming and keeping great ice.  White helps keep the ice from melting by reflecting the radiant heat away from the rink on those sunny winter days.  Iron Sleek manufactures high quality ice rink liner using only virgin polyethylene resins, in pure white, and multilayered.  Multilayered liners are much stronger than a single layer.  WE DO NOT USE RECYCLED MATERIALS FOR YOUR LINERS as the first melt is the best melt.  Some lower cost options that can be found at the local hardware store may be made of recycled materials since they are not specifically made for winter ice rinks.  The first resin melt produces the highest quality plastic which is required to absorb the abuse of a cold winter.  Our manufacturing recipe is proven successful for outdoor natural rinks while recycled solutions are a compromise.  Also, we provide ice rink liner at widths that are perfect for making home ice rinks to be 20 wide, 30 wide, 40 wide, and 50 wide.  Our widths are specifically manufactured for those who are building backyard rinks.   If you are a park or recreation center, we also have liners as big enough to make an NHL size rink.  Do I really need a liner?

What mil thickness?

First of all, mil refers to the thickness of a liner in thousandths of an inch (i.e. 6 mil= 0.006”).  Iron Sleek recommends using the "flood method" where you flood a framed and lined enclosure (like building a swimming pool).  With the flood method, the liner is simply an impermeable. That is, it keeps the water from passing through. Reality, however, is that winter freeze/thaw patterns causes rinks to creep throughout the season. Although 3 mil is impermeable, it is too thin to endure the extreme winter patterns in North America. 5 mil and up is our recommendation for outdoor ice rinks. Iron Sleek goes the extra mil from 5 to 6 mil to assure your success.  Iron Sleek 6 mil Liner also has the multiple layers required for rinks...Layers will get you more toughness--like skin.  6 mil or 20 mil, a skate through the ice will still cut right through the liner so do not waste your money on extra heavy duty liners!  If you have rocky conditions, a string reinforced liner may be a better solution for you.

How Big?

Minimally, a liner should be big enough to cover the entire skating surface and should be able to come all the way up the boards and then droop down a bit on the exterior.  The liner should be at least 4 feet wider and 5 feet longer than the skating surface or more. For example, a rink that is 30 by 50 should use a liner that is at least 34 by 55. It is always good to have extra liner just in case you need to use taller boards. Remember, too much liner is not a mistake while too little is.  Long liners are easily trimmed for aesthetics!  Use Iron Sleek Rink Topper to hold the liner in place and to give your rink a nice appeal.  Iron Sleek liner clips are an affordable alternative to rink topper.  One more important consideration on sizes is to beware of nominal sizes versus actual sizes.  Tarps are usually nominal sizes while liner are actual sizes.  That would mean that a tarp can be smaller than the listed size.  With Iron Sleek liners, you will always get enough liner.

Can a liner be reused?

Take my word for it, cut out a few Starbucks coffees and save your money for a new liner every year. It is not worth the panic of "did I cut the liner" or "do I have a leak". I have tried to keep my liner in tact in the past only to fail every time. Since my wife would never let me put that stinky monstrosity in the basement or garage, I tried to store it in the outdoor shed where I had creatures nibble holes through it, mold infestations, and rancid unexplainable stink. Buy a fresh clean liner every year. Use your old liner to cover your lumber in the off season or just recycle it since it is LPDE #4. If you insist on saving your liner, just use it as a bottom insurance layer for the following year. Do not worry so much about liner cuts above the ice level. Cuts beneath the ice are highly relevant so I strongly recommend protecting your liner from failing during the skating season with Iron Sleek Base Cove.

Do the Liners or Tarps kill the Grass?

Liners should be laid down only before a deep freeze is coming. By that time, the grass is dormant anyway. Snow covered grass gets little to no sunlight while grass still comes back every year. The problem occurs when you leave your liner/tarp in place during the time your grass becomes active.  I learned that using a true white liner buys you a little time and forgiveness which helps for healthier end of season lawns. If you lay your liner down on dormant grass and take it up when the grass is still dormant, you will be just fine with whatever you lay down. Some will advertise that white/black liners as grass killers, but boards and brackets are equally 100% opaque. Ice Rink Brackets and rink boards haven't killed my grass. It's all about timing and dormant grass. Also, there is no one who will guarantee that your grass will come back but it usually comes back better, at least that is what my experience and customers all tell me. We cannot control the weather and a fluke season could happen where the grass could be tricked to become active. My opinion is that a backyard rink is worth the minimal risk of losing your grass.

More on Liners.

Treat your liner very carefully when installing it. Be sure that nothing sharp is in your rink area or on your boards. Be sure that no screws are pointing into the rink interior. Tuck your liner down nicely into the rink. Fill the bottom gaps with soil or use Iron Sleek Base Cove. Do not staple your liner until it is settled when the rink is full of water. Iron Sleek Rink Topper is a great alternative to stapling. Never walk on your liner unless you have an emergency. In that case, do not where shoes, go in with 2 layers of socks on.  Never reach into your rink enclosure with tools, you will drop them and you will be sorry for your liner and your tools.
