Can You Put FRP Over Plywood? (How To)

There are many advantages to using FRP panels. They provide quality, durability, and strength. Are they also something that can be applied over plywood?

You can install FRP panels over plywood and any other solid wall surface. The real key is to prepare the surface before you install the panel so that there are no defects. You should then use the proper adhesive for this job.

FRP panels are commonly used in commercial areas, such as in factories and hospitals. They are well-known for the benefits they provide and although there is an extra cost involved, it is often worth the money that was put into it.

When it comes to FRP, most people think about fiberglass-reinforced panels, which is what the acronym stands for. There are many different systems in place, however, and each may provide different benefits.

For example, some FRP systems strengthen for seismic activity or perhaps help on bridges where there is additional strength that is needed. Others, however, are typically used in place of drywall or perhaps over drywall to provide additional benefits.

Although you might find these in many industrial settings, they can also be used in the home. They provide many of the same benefits that they provide for industry, but they do so on a more personalized level.

As is the case with any type of project, if you are installing an FRP system in your home or place of business, it’s important to consider safety. This may be seen on any number of different levels.

One of the benefits of using FRP is that they are very thin. Along with it, they don’t carry much weight so you don’t have to worry about lifting heavy objects in order to use an FRP panel and put it in place.

That being said, anytime you are bending and lifting it is important to ensure that you do so properly. The last thing you want to do is injure your back in an effort to put something up on the wall.

When you’re cutting FRP, it’s also important to consider your respiratory health. This is something that is often overlooked but there are composites within FRP that can be dangerous when they are airborne.

This can clearly be seen in the case of fiberglass. If fiberglass is breathed in, there can be damage to your respiratory system. Of course, it may not be necessary to wear a full-face respirator but you should at least consider using an N95 disposable respirator.

Other matters of safety include protecting your body parts, such as wearing safety glasses, cut-resistant gloves, and long sleeve shirts. It may seem like an inconvenience to do so but it is much more inconvenient to lose the availability of your eyes or fingers in the process of doing a DIY project.

Should You Put FRP Over Plywood?

One of the questions that many people ask is if you should put FRP over plywood. We’ve already established that it is possible to do so but the decision to do so is one that depends upon why you need it.

In order to make this decision, we should consider some of the benefits of using FRP. You can then make the choice as to whether to install them or not.

Maintenance – When compared to other types of wallcovering, FRP provides a very low level of maintenance. Generally speaking, you can simply wipe them down to keep them clean, and otherwise, there isn’t anything you need to do.

Resistance – Many types of wallcovering, including drywall, provide a suitable living environment for mold, bacteria, and mildew. FRP, on the other hand, does not support the growth of either mildew or mold and they are not appropriate for the growth of bacteria.

Of course, you will need to clean the FRP with an appropriate cleaner depending on where it is installed. With that simple cleaning, however, you have something that is healthy for the environment.

Money – If you are trying to increase the capacity of the wall without adding a significant amount of mass or weight, then FRP can do the job. It is also relatively inexpensive, so you don’t have to worry about blowing your budget.

Strength – One of the real benefits of FRP is the tensile strength it contains. It can add an amazing amount of strength by just adding a layer to plywood.

Installation – FRP panels adhere to plywood using adhesives or you can use mechanical fasteners if you choose the proper fasteners and use them according to the manufacturer’s instructions. If you have to cut the FRP in the field for installation, it is very easy to do.

Tool Needed To Install FRP Over Plywood

When you are preparing to install FRP over plywood, it’s important to gather your tools and have them readily available. This will make it easy for you to get the job done.

Fortunately, there are not many tools that are necessary when installing FRP over plywood. Here are the tools you should have on hand:

Saw – You can cut FRP panels with any number of different power saws. You should have a masonry blade installed for easy cutting so that you can cut multiple panels without changing blades.

Drill – It is possible to drill an FRP panel with a metal bit. It is only if you are installing FRP over concrete that you have to use a masonry bit.

Straight Edge – You can use a level as a straight edge and you have both tools at one time.

Square – A Carpenter Square or combination square can be used.

Roller – A roller will remove air pockets and improve adhesion.

Goggles – It is generally recommended to wear goggles to protect your eyes fully.

Respirator – Typically, wearing a disposable N95 respirator or something compatible will suffice.

Gloves – A good pair of cut-resistant gloves or all-purpose gloves will work well.

What Preparation Is Needed To Install FRP Over Plywood

Although there is not much preparation that is necessary for installing FRP over plywood, you should still install it after the preparation takes place. Here are some things to keep in mind.

Storage – If you are not using the FRP panels immediately, you should store them in a dry area. They should also be stacked on a dry surface after removing them from the skid. Do not allow the panels to remain wrapped for an extended amount of time.

Acclamation – Make sure that the panels are in the same room as the installation for at least 24 hours. Otherwise, shrinkage or expansion may be a problem.

Temperature – Everything involving the installation of FRP panel should be above 50°F. This includes the panels, the room, the plywood that has already been installed, and even the adhesive. After you install the FRP, make sure that no major fluctuations in temperature occur within 24 hours.

Inspection – Always inspect the panels before installing them. If there are any defects, they should be returned for replacement.

Plywood – If there are any defects in the plywood, they should be fixed before the FRP is installed. This includes adjustments at the seams or loose/rotted plywood.

Now that you have prepared for the installation of FRP, it’s time to get the job done. Here is how to install it properly.

1. Measure and Cut – You should carefully measure the area and then cut the FRP to match. FRP panels can be cut with any type of power saw using an appropriate blade.

2. Adhesive – There are specific types of adhesive that can be used for FRP panels. Check with the manufacturer to see what type of adhesive should be used for the FRP you purchased.

Consider safety carefully when it comes to applying and working with the adhesive. Don’t allow it to get on your skin and make sure the area is well ventilated. Many types of adhesive are also highly flammable, so do not work near heat or open flame.

Always apply the adhesive over an even surface. This is something that should’ve been checked before you apply the FRP. Any uneven surface will lead to a failure of adhesion.

If you don’t have the ability to use adhesive, there are mechanical fasteners that can be used. This is not a typical application but if you use fasteners, they must be of the proper type.

Some of the options that are available include chrome pin rivets, stainless screws, and plastic pin rivets. Essentially, the mechanical fasteners have to be non-corroding and they must be installed according to the manufacturer’s instructions.

If you have plywood and would like to strengthen it, you can install FRP panels directly over it. Plywood, along with other solid surfaces makes a great base for the installation of FRP. As long as the surface is free of defects and even, you can apply the adhesive and begin installing the FRP.
