Aside from wood putty and wood fillers, can you also use epoxy for wood repairs? It is common to have wood repairs for a while after doing your project. Epoxy is one of the common materials for repairs, but can you also use it on fixing your wood projects? Let’s help you with how to do wood repairs correctly.
Epoxy is a repair material for stopping leakage and repairing other materials. The good news is that there is special wood epoxy for fixing some rotten parts or filling in a hole on your wooden projects. Wooden epoxy works just like wood putty and fillers. This material is easy to handle, mix, and use in molding. It also hardens quickly so you can finish the job efficiently.
Epoxy is an all-around repair material for different materials. Whether you’re just filling a hole or a gap in your wooden piece or removing a rotten area – epoxy will do the job for you. However, you have to make sure that you use it correctly to avoid ruining your project.
9 Easy Steps On How To Do Wood Repairs With Wood Epoxy?
Let us help you mix, apply, and shape epoxy for wood repairs. Once you know a few tricks to blend and add epoxy, you’ll find it as easy to use. Most of the fixes would take only a few hours, using equipment that you probably already own. So, here some materials and tools that you need.
|Tools Required||Materials Required|
|Chemical resistant||Alkyd primer|
|Drill bit set||Epoxy|
|Drill/driver – cordless||Quality acrylic paint|
|Gloves||Small (8 oz.) squeeze bottle|
Step 1 – Assess The Problem
Just like any other kind of repair, you have to assess the root cause of the problem. Is there any rotten part? Or is it just a hole that you have to fill-in? Check the area around the damaged wood with the awl or screwdriver to determine the rot’s severity. Softwood usually is more prone to rotting that eventually leads to decay of the whole material if you don’t remove the rotting part.
Step 2 – Remove The Rotten Part
After locating the cause of the rotten part of the wood, start the repair by stripping off the old paint and gouging out all the rotten parts using a paint scraper, chisel or old screwdriver. Then, drill ¼ – inch holes with 1-inch space each to allow the epoxy consolidant to soak into any water-damaged wood surrounding the repair. Drill it deeply without passing through the other side of the wood. These holes will allow moisture to escape and will act as reservoirs for the consolidant as it runs through the wood’s core.
Step 3 – The Magic Of Liquid Wood Epoxy Consolidant
Mix the two sections of liquid epoxy consolidant wood according to the direction of the supplier. Squeeze the material into the 1⁄4-inch holes and onto the wood in the repair area. Continue this process until you find the saturation point of the wood. Next, install a loose-fitting plastic tent over the repair to shield it from rain and let it dry for at least a week before continuing.
Step 4 – Mix Your Wood Epoxy
You don’t have to wait for the solidifier to harden fully before filling it with an epoxy wood filler. After mixing the epoxy, you only have 30 minutes before it starts to get hard again. So, apply swiftly but with greater accuracy. The epoxy allows adequate working time under normal conditions, but the temperature is the main factor.
The heat accelerates the reaction, while the cold slows it down. So, make sure to use it to your advantage. Keep the epoxy products cool at around 70 degrees Fahrenheit as you mix to add epoxy. If you want to speed up the hardening process, use a blow dryer to harden the epoxy repair process.
Step 5 – Fill In The Wood With Wood Epoxy Filler
Apply the wood rot epoxy filler to the area that you want to repair with a putty knife. Then, spread it as hard as you can to cover all the voids. Fill out every gap and hole to ensure a strong bond. Do it as accurately as possible to avoid wasting materials.
Step 6 – Overfill the Area with Epoxy
You can use your fingers to shape the epoxy, depending on your project’s surface. Just make sure to wear chemical-resistant rubber gloves to avoid ruining your hands. You can do it by overfilling the repair, and ensure that there are some extra for proper shaping.
Push the epoxy filler to an approximate shape with your fingers and a scrap of wood, adding the filler as required. Don’t try to get the ideal form; make sure you leave enough material to suit the surrounding profiles. On warm days, the epoxy should be strong enough to start forming in around three to four hours. Enable the patch to harden overnight in cool weather.
Step 7 – Cut The Shape With A File
If you can’t break the epoxy with your fingernail, it’s difficult enough to start filing. When hardened, you easily shape and sand the material with regular woodworking methods. Start by roughing the basic contour with a Surform plane or a rough rasp. Once the form begins to appear, start working on the details or formation of your object.
This step depends on the profile you are re-creating. You may need a flat, round, or half-round wooden file. There are also some instances when you have to sand it with 80-grit sandpaper. Using the surrounding wood profile to direct your tools as you slowly extract the hardened epoxy.
Step 8 – Smooth The Surface
Once you get the correct shape, you can start sanding the surrounding wood with 80-grit sandpaper and 120-grit sandpaper. If you’re sanding, wear a dust mask and eye protection. Vacuum the dust out of the patch. While doing the final sanding, make sure you scrape up the surface of any hardened consolidant that covers the surrounding wood. Otherwise, the paint will not adhere to it.
Step 9 – Add Some Color
Painting is optional, and it depends on your project. Seal the patch with an alkyd primer and two top-quality acrylic paint coats over the epoxy and surrounding bare wood. Before adding the final coats of finish, seal the joints between the separate pieces with polyurethane caulk. Inspect the patched area at least once a year and repaint or repair it whenever required.
Frequently Asked Questions
Here are some commonly asked questions about using epoxy for wood repairs.
What is epoxy wood filler?
An epoxy wood filler is a great way to fill in gaps and holes and even restore rotten wood. It can be a cost-effective material that you can easily use for any wood repairs. It acts as a wood putty and filler at the same time. Just make sure to make a proper application.
Does epoxy make wood waterproof?
Manufacturers already create waterproof wood epoxy for a resilient finish. Therefore, it is also ideal for repairing wooden projects with high exposure to water, wear, and moisture. Just make sure to read the label and check that it is waterproof.
Can You Sand Wood Putty?
Sanding is beneficial before and after the application of a wooden mastic. Before applying, make sure the hole is free from dust and burr. Instead, after drying, you have to smooth the surface to add the desired finish. Fine-Grit sandpaper or a hand-held oscillating tool fitted with at least 220 grit sandpaper for the smoothing of wood putty.
You can find many epoxy brands, but the precise mixing and application methods differ slightly depending on the manufacturer. Follow the supplier’s instructions carefully. Every brand often uses a two-step process consisting of two types of epoxy – a syrupy liquid solidifier, and a putty-like wood paste filler. More importantly, select the right form of epoxy for wood repairs.
