Are you struggling with the correct way to Filling Large Voids in Wood with Epoxy? Do you want to know the proper way to prepare your large voids for later filling with epoxy? Please read the article below to give you a detailed step by step (with no step skipped) process on how to fill large voids or cracks in wood with epoxy.
STEP 1: SURFACE PREPARATION
STEP 2: TAPING OFF THE BOTTOM VOIDS
STEP 3: POURING THE EPOXY
Measure out the epoxy that you need for your project, depending on the size and number of the voids.
If your epoxy includes a hardener, keep the measurements accurate because any inaccuracy could lead to the surface curing for too long or too fast.
As a side note, some of the epoxy resins come with measuring pumps that exceedingly ease the measuring. Mix the epoxy depending on the instructions of the epoxy. Slowly start applying the epoxy resin to fill cracks in the wood.
While filling wood cracks with resin, and large ones for that matter, it is absolutely vital to work in phases. Depending on the size of your void and the strength of the tape, divide your epoxy into phases such that you apply then wait for that phase to dry before pouring an additional phase of epoxy.
Without this careful pouring of epoxy into large voids, numerous projects go to the drain due to the unstoppable epoxy leakage. Too much epoxy at once causes too much pressure on the bottom tape that hence causes leakage and is no fun. Also, working in phases keeps you in control of how much epoxy you consume, avoiding wastage in the end.
Additionally, it is important to start from one end of the void or crack while poring epoxy and let the epoxy flow across to the other side, filling the bottom of the void. Failure to follow this step frequently results in big air bubbles underneath or in the middle of the void, which is unsightly as far as epoxy craft is concerned.
For filling large voids in wood with epoxy, we recommend specific products that could be of great importance in improving the look and feel of your final surface.
One is the epoxy you use for your most part, which should be a deep pour epoxy with the crystal-clear feature that allows one not only to mix the epoxy with a pigment but also to make subsequent pour layers to expose the pigment underneath. Two, a durability-based epoxy with features such as ultra UV resistance should be the second layer to ensure a firm surface.
STEP 4: SANDING
Instead of poring the first layer of epoxy and following it up with its subsequent layer later, then sand all the layers all at once, it is beneficial to sand in between layers because this exercise reveals some of the air pockets that can be filled as once continues to pour the epoxy.
You don’t want to wait for the curing time between layers and still find small cracks and holes just after sanding all the layers. In using resin to fill cracks in wood, it is crucial to hold your sander flat and level. If you start digging with one side of the sander in trying to get rid of the excess epoxy faster, it is highly likely you’ll end up in inconsistencies.
STEP 5: FINALISING
After sanding, then blow all the holes and cracks to eliminate the sanding dust to avoid sand particles getting trapped in the epoxy that would significantly reduce the quality and aesthetics of the woodworking project. If available, use a vacuum blower that is far more efficient than regular blowers.
After this, then your second layer of epoxy should come right in. A trick to do here is to overfill the void just a hair high because the epoxy will sink a bit as it cures.
It is at this point that you want to employ your blow torch or heat gun or any such heat source to get the bubbles out since working with epoxy produces surface bubbles very often, and filling wood cracks with resin is a no exception activity.
Once the top layer is cured, it’s time to go back to the project with the sander to sand the epoxy layers off back down with the wood. No matter how careful you are, it is highly likely that you will end up with little holes. This phenomenon is due to the nature of crevices, some of whose faces face different directions and, as such, may contact the epoxies at different times, thus depriving the surface of some epoxy and leaving small holes.
To eliminate small holes quickly from the surface, one can use a cyanoacrylate glue such as Instant Bond Glue and Accelerator by Titebond. This technique should be repeated if desired results are not achieved, but the first time the glue enters into the surface is often enough to fill holes in wood. Do not forget to sand the glue again right off to ensure a clean surface for your woodworking surface.
Finally, it is a worthwhile activity to fill large voids in wood with epoxy. If large voids are to be cut off from wood, it is highly likely one could lose a big chunk of the wood available for then to the hobby. There are several challenges in the process, especially of preventing leakage and blowing off dust. However, large voids provide the woodworking hobbyist with an excellent chance to show extra detail due to the larger space meaning the surface with epoxy performs its actual function of making its users engaged and excited.
