So, is this Thompson Water-Seal a water or oil-based stain? Well, it’s undoubtedly an oil-based stain that’ll also seal the wood against water infiltration in addition to getting into and blocking off the wood pores.

Cleaning up for Thompson Water-Seal application requires using just water and soap. Also, remember to follow the manufacturer’s stain usage instructions.
