I don’t know if it’s the weather or what but I have a large plastic container of sanding sealer which has become very thick. It now resembles custard and I have been told that you can add thinners to it to make it more easy flowing any ideas Alistair

See if it’s lacquer based sealer and if so you can get some lacquer thinner at a paint shop.
If it’s water borne just use tap water.

Hi Bob it smells like it’s got thinners I will try alittle bit with water but I am sure it’s going to be thinners I need . I didn’t know if I could add this, or not. It’s a big container and I don’t want to chuck it out or ruin it thanks Bob Alistair

It could be shellac based which I believe is dissolved in alcohol / methylated spirit, but it sounds like you’ve already identified it as cellulose. Should be no problem in diluting with cellulose thinners.

If it is in a plastic container, I seriously doubt that it’s lacquer. Lacquer will usually melt plastic. You may just have to experiment with different solvents to figure it out (on small samples of course)

Good luck Alistair

I transferred it into this container a few years ago it was in another similar container I have had it for a while hence no labels etc.Alistair

Alistair, it really does not matter which one you use. Lacquer thinner and denatured alcohol will combine. So you can use either one to thin your shellac. Given the plastic container, if it were me, I would use denatured alcohol.
