Feast Watson Proofseal is a 250ml clear barrier coat that seals interior timber before or after decorating, locking the surface against moisture and contaminants migrating through.
Use it as a sealing coat on interior timber surfaces and joinery where a barrier layer is needed under or over other finishes. Apply thinly to clean, dry timber, allow the full 12 hours before recoating, and clean brushes in methylated spirits.
Feast Watson 250ml Proofseal Interior Barrier Coat is a penetrating sealer designed to lock in timber tannin and oils, preventing discolouration and adhesion issues.
This product serves as an effective barrier coat for naturally oily timbers such as Spotted Gum, Brush Box, and Tallowwood. It seals the timber, reducing the tendency for lighter coloured timbers to darken after top coating. Proofseal can be overcoated with various Feast Watson finishes, ensuring versatility in application. Ideal for both new and previously coated timber, it requires proper surface preparation for optimal results.
