What To Do If Epoxy Doesn T Harden

If epoxy residue is left on the floor the new epoxy will bind with it.

Cloudiness when epoxy resin hardens epoxy resin should dry clear but this can change if moisture is introduced to the resin or the surface where the resin is meant to be applied. Sticky or tacky epoxy. Unfortunately epoxy resin is too soft to do that with. If there are no soft spots or runny epoxy on your project you can simply pour properly measured and mixed resin over the epoxy surface.

If your epoxy has already cured and you have fish eyes you will need to pour another coat over the epoxy. However if you found that the initial problem was that the temperature was too cold move your resin piece to a warmer spot and give it 24 hours you may find it will cure fully then. Another method try and apply your epoxy in thinner coats. If the ratio is wrong then heating won t do a damn thing.

So make sure that the surface is completely clean and dry. Sticky or soft spots. If the tackiness is sporadic caused by uneven mixing the uncured epoxy paint may be removed and covered with a new application of properly mixed epoxy paint. Scrape and wipe up as much of the tacky epoxy paint as possible.

What to do if epoxy doesn t harden here are a few more options. As for the coasters i would put a mug with hot coffee in it on the coaster but i wouldn t take a mug that had just come out of the microwave with boiling water in it and put it on the coaster. If you find the entire surface sticky you can sand this off by using some 80 grit sandpaper. Also use an epoxy resin that is already mixed and inside a double barrel syringe.

Then let it cure properly. After epoxy is poured and has cured for 36 hours the surface should be hard and smooth. Try applying the epoxy when the temperature is warmer as epoxy tends to be thinner in warmer temperatures. Clean the area thoroughly and then pour another accurately measured and mixed resin coat layer.

Heating it will not help because two part epoxy doesn t work by simple dehydration. The hardener needs to strip the side branches of the epoxy to produce a free radical.
