FRP wall panels are a great product for the DIY community. The panels are strong, long-lasting, grime and vandalism resistant. Excellent for applications such as bathrooms, garages, “mud rooms”, or areas animals are kept. FRP wall panels have a relatively economical cost compared to industrial FRP panels, are widely available, and easy to install. As with any project, preparation is key to saving money and prevent disappointment with the final result.

To start the first thing you want to do is draw a quick sketch of the area to be covered. Mark each wall with how many feet it is in length. FRP wall panels come in 4′ x 8′ and 4′ x 10′ panels and the next thing you need to do is figure out how you will orientate the panels. Start at the floor – will they be arranged to provide more height by being set side-to-side by their width? or by their length to provide 4′ high coverage? In many applications, the panels can be placed on their side to cover more area and reduce costs. You should now be able to figure out how many panels you need.

Next, figure out how much FRP adhesive you need. The adhesive comes in 4 gallon buckets and covers 200 square feet. simply add up the total area of the panels you need and divide by 200. For example, if your project requires 12 4′ x 10′ panels that is 480 square feet / 200 = 2.4 or 3 buckets of adhesive will be needed. It’s always good to have some extra so never round down!

Following this step you need to figure out how many inside corners/outside corners/j-trims you need. Inside corners and outside corners are PVC plastic dividers for FRP wall panel that are purchased alongside the panels. This is pretty simple as you just count how many corners you have. The trims and corners all come in 10′ lengths. The j-trims require a bit more thought. These are also PVC but are used to join two panels where there are no corners. You need to be able to sketch or visualize where your panels will buttress up against each other along the stretches of wall and be able to count up what you need.

And that’s pretty much it! At this point you should have a clear idea of the scope of your project and all the requirements for your FRP panels and how many accessories you need. The next step is to simply contact your plastics distributor and request a quotation. Please give clear and specific requests including relevant quantities for all required components. That will ensure a quick and accurate quotation.

UHMWPE (Ultra-High Molecular Weight Polyethylene) often abbreviated as “UHMW” is one of the most popular and well known industrial plastics. UHMW is seen as a “Jack of All Trades” in many applications while being more available and less expensive than other plastic options. While this is true to a degree, UHMW has limitations that means it will not solve all problems in all situations. In fact, it has some properties which make it deficient and the “DIY” community should keep this in mind.

When to use UHMW:

UHMW excels at taking impact and it is virtually unbreakable, it’s also very slick and the colder the operating temperature is, the better it performs. This is why UHMW is so popular in applications such as toboggans or as rails on sleds: impact + cold + slickness are all important to the application, and it does really well in this application. UHMW is also easy to work with as it drills, saws, and lathes well. It functions as wear pads, sliding blocks, fenders, and in other impact absorbing applications.

When NOT to use UHMW:

The main application we here at Redwood Plastics see UHMW incorrectly used in is bearing applications. UHMW is a poor choice as a bearing for two reasons:

1.) it is difficult to machine to tight tolerances (+-) 0.02″ are the best you can usually hope for and

2.) UHMW has low load bearing capabilities (500-800PSI). In a DIY bearing application nylon or Tuffkast will be superior.

The issue with tolerances is important to hit home: UHMW is not a dimensionally stable material. Not just compared to metals but even compared to many other plastics. We regularly receive drawings and requests for UHMW parts where we cannot quote based off the requested tolerances (or have to get a written waiver for acceptable tolerances). This lack of dimensional stability extends to thermal expansion and contraction which is why it is so hard to guarantee tolerances: if the part is manufactured in 30 degree weather but used in 90 degree heat the dimensions of the UHMW will drastically change!

We hope this points you in the right direction if UHMW is or isn’t right for your project. But if you have questions, or might be wondering what an alternative material could be, please contact us and we’d be glad to help!

Believe it or not one of the most popular “DIY” plastic projects is making bushings. It makes sense as bushings are a part of so many applications and plastics are an excellent bushing material, outperforming metals such as bronze and babbit in many situations. Plastics are easy to machine and usually last much longer than metal in a bushing application. Cast nylon is probably the most popular material for bushings, as it can take loads up to 4,000PSI and is readily available in filled grades to increase wear resistance and low RPM performance (moly-filled nylons) and reduced coefficient of friction or reduced lubrication requirements (oil-filled nylons). Nylon does have three weaknesses: shock/impact, cold, and water. If impact may occur to the bushing, if it’s in an environment -10 degrees Celsius or below, or in a wet (or marine) operational environment then Redco Tuffkast by Redwood Plastics may be an ideal solution for all three problems. It is a bit softer and can handle a little less load but in many DIY applications this will not matter.

Redwood Plastics offers a handy bearing machining guide that not only supplies typical running clearances but gives an honest comparison between nylon and other bearing materials. You can find the PDF Bearing Machining Guide here.

-Build your own twin-wall polycarbonate greenhouse

-Drill holes in PVC piping and affix to a garden hose in order to make a great summer water attraction for the kids

-Make home saw guides made out of Micarta

-Line your mud room with FRP wall panel to protect from grime and damage

-Replace your wooden dock with a mini-mesh FRP grating surface

-Cut and affix UHMW strips to your snowmobile steering rails or dog sled
