Wood rot is a form of wood decay that occurs when wood is exposed to moisture for a long time. This moisture allows fungi to grow in the wood, which breaks down the wood fibres and weakens the wood. This can eventually lead to serious damage.
Wood rot mainly occurs in wooden structures that are not well protected against water, such as window frames, doors, cladding and roof edges. It is important to detect and repair wood rot as soon as possible to prevent further damage. With epoxy you can easily repair the wood rot and restore the affected wood to its original state. In this article we answer the question: "How do I repair the wood rot of my window frame or door with epoxy?". We explain step by step which steps you need to take and which products you need.
To repair wood rot with epoxy you will need the following products:
First of all, you must thoroughly clean the rotted parts. Remove all rotten wood with a wood chisel and screwdriver until only good wood remains. After removing the rotten wood, ensure that the wood is properly cleaned and that all wood residue is removed.
Mix epoxy resin with rapid hardener to impregnate the substrate. It is important to use the correct ratio, so weigh the resin and hardener accurately with a kitchen scale. Mix at least 150 grams of epoxy (100 grams of resin and 50 grams of hardener).
Apply the mixed epoxy with a small flat brush to the bare areas where the rotten wood has been removed. Always wear nitrile gloves to protect your hands. Then let the epoxy cure for 1 to 2 hours, depending on the temperature. It is important not to wait longer than 24 hours before doing the next steps to ensure a good chemical bond.
Now that the substrate has been impregnated, it is time to fill the holes with a mixture of epoxy resin and cotton fibre. With these two products you can easily and cheaply make a fillet. Follow the steps below to make a fillet connection:
Step 4. Finish the window frame
After filling the holes with epoxy paste, your rotten window frame is almost repaired. Once the epoxy has completely hardened, you can start finishing the whole thing. You can do this with a sander or simply by hand. Please sand with 120-180 grit.
By properly implementing the above step-by-step plan, your window frame will look like new again and can last for years to come!
