From the Feast & Watson product page:

"Ensure that super smooth finish to your timber with Feast Watson Sanding Sealer.

Preparation is the key to all successful projects, and preparing your timber surface for coating and staining is no different.

Our timber floor sealer is a clear, fast drying timber seal that dries to fill the timber grain, providing you with a beautiful, smooth canvas for your timber coating."

Whilst it does say "floor sealer" in the blurb, it's the same product as mentioned and linked in the earlier post.
