Powder Vs Ready Mixed Fillers

In general, you would come across two types of fillers; powder and ready-mixed fillers. The powder fillers are either water-based or solvent-based. Powder filters are preferred by professionals and DIYers so that they can mix them according to their choice.

Wall fillers that accept all types of paints like emulsifiers, solvent-based and epoxy-based paints are best. Be careful before buying as some of them are not compatible with the epoxy-based or solvent-based paints.
