Epoxy resin is adored because of its crystal clear appearance and the glass finish. With time however, wear and tear may set in. The older epoxy surfaces, particularly countertops, tables and floors, are usually cloudy, scratched, peeling at the edges, or dull.
The good news? Most of the times, you do not need to make a fresh start at the beginning. Such a shiny finish can be restored and the life of your epoxy project can be prolonged by the right steps of preparation, sanding and re-coating.
This guide walks you through the process of resin repair and recoating epoxy step by step.
Epoxy is durable, but signs that it may need resin repair or recoating include:
In the event that the base layer remains solid it is often possible to recoat rather than to replace the entire piece.
Before starting, gather:
Test to see whether the epoxy is merely scratched/dull or it is peeling off.
Sanding produces a rough profile in order to enable the new epoxy to adhere to the old surface.
Tip: To make them smoother, do not skip grits but add them gradually to 320-400.
Sanding should be followed by wiping off the dust using vacuum or microfiber cloth.
Cover edges or walls or places that you do not want resin to flow.
Combine in the proportion as specified by the manufacturer (usually 2:1 or 1:1 volume). Do not stir, to form as few bubbles as possible.
Allow to cure, typically 24-72 hours, product and conditions vary. exclude dust, insects and humidity.
Frequently as a result of exposure to moisture. Sanding back: After sanding it off, be sure that the surface is bone-dry before repainting. Future yellowing/cloudiness can be avoided by applying a UV topcoat.
For light scratches only:
When the scratches are deep then full flood coat is advised.
Once your epoxy is repaired, do the following to protect it:
Q: I have old epoxy, do I have to take it all off before recoating?
No, simply take away loose, peeling, or otherwise damaged portions. In case the base layer is solid, adhesive sanding is sufficient.
Q: Is it possible to pour new epoxy on top of yellowed resin?
Yes, but there will still be the yellowing underneath. You can think about sanding over/adding pigments/tints in your recoat to cover it.
Q: To what thickness can I pour a repair coat?
Stick to thin flood coat (1-2mm) in case of recoats. To fill the gaps in places that are thicker, pour in to avoid overheating.
Q: Does I have a chance to repeat polyurethane coating rather than epoxy?
Yes, epoxy can be refreshed with clear polyurethanes (as with water-based floor finishes) which will give it UV protection, but not as effectively as epoxy itself.
Epoxy can pass as glass, but you are able to repair it and restore it without replacing the entire surface as in glass.With proper resin repair and recoating epoxy, you can restore cloudy, scratched, or peeling areas to near-original shine. A little time and preparation can save money, reduce waste, and give your project a new lease on life.
It will cost a small preparation, and time, but your epoxy can look as new, and you save money, produce less waste, and rejuvenate your project to a new lease of life.
Don’t scrap it - restore it. Epoxy is built for the long run, as long as you know how to maintain it.
