Unfortunately, we don’t recommend spot fixing for the simple reason that it’s actually very difficult to sand out a small area where there might be an issue, such as a bubble, hair or even a bit of dust that settled into your wet resin. It's almost impossible to get a seamless finish by pouring a fresh patch of resin on top of the original resin coat.
Instead, we recommend that you sand down the entire surface and pour another well mixed, well measured coat of Craft Resin over the entire piece for an even, flawless finish!
How To Apply A Second Coat Of Epoxy Resin:
First, sand down the entire surface of your piece with coarse sandpaper ( we use 80 grit sandpaper ). Sanding will not only get out the imperfection, but will also serve to provide some tooth between the first and second layers.
It will look very scuffed in the short term, but don't worry, once you pour the second coat over top, all of those sanding marks will disappear.Wipe away any of sanding debris before you pour your next coat of well measured, well mixed Craft Resin over the top, then cover with a dustcover to make sure you avoid any of those imperfections a second time and you should be good to go!
How To Fix Sticky Spots:
If, after a day of curing, you’ve noticed some soft sticky spots in your resin, it means either one of two things: either the delicate 1:1 balance of resin and hardener was off, or the material just wasn’t mixed thoroughly.
Resin that hasn't cured will stay sticky until steps are taken to fix it. You'll need to scrape off any of the unmixed material and re-apply a fresh coat of resin, and your piece will look as good as new!
Why Did The Sticky Spots Occur? It's super important to scrape the sides and bottom of your container as you mix your resin and hardener. If you don't, you may end up with unmixed resin and hardener stuck to the sides of your container that could cause sticky spots.
So remember: always scrape the sides and bottom as you stir to make sure that the resin is 100% mixed and, therefore, 100% catalyzed.
How To fix An Uneven Coat:
Simply apply another layer of Craft Resin epoxy resin overtop once the first layer has cured. Remember to keep your piece perfectly level to avoid having the same thing happen twice. Make sure to sand in between the layers so they adhere to each other properly. The second coat will go over the first and be perfectly clear.
How To Stop My Resin Going Milky Or Cloudy:
Craft Resin's ideal working temperature is between 75-85F or 24-30C. Resin colder than this is thick, clumpy, hard to work with and looks milky because it's full of thousands of micro-bubbles.
(which you'll never be able to torch out)
Carefully warming up the unopened resin/hardener bottles in a warm water bath for about 10 minutes can greatly mitigate this issue.
Be aware that warming your resin in a water bath cuts down your working time by about 10-15 minutes, so time yourself accordingly.
Dry your bottles thoroughly after removing them from the water bath - even a single drop of water into the mixture can cause it to turn cloudy and prevent it from curing properly.
