SiOO:X End Grain Sealer Surface Protector (Part 2)

It is vital to treat all cut ends with an end grain sealer to prevent moisture ingress into treated timber members. All factory-treated SiOO:X timber will be treated on the surface and on the edges. Any end cuts in cladding boards, deck boards, and other trim need to be sealed at installation.

The prime reason for sealing wood end grain is because when exposed it absorbs moisture up to 250 times more rapidly than other wood surfaces. Unprotected end grain can lead to interior rot and discolouration adjacent to the cut end.

End-grain is particularly vulnerable to moisture, and early failure is often seen at joints and corners where the end- grain is exposed.

The SiOO:X End Grain Sealer comprising Wood Protector and Surface Protector stages is easy to hand brush apply and brings the advantage of the proven penetrative SiOO:X long life silicon protection. It is entirely compatible with the SiOO:X Premium Wood Protection system. 

The application is one coat of the End Grain Sealer Wood Protector and one coat of the End Grain Sealer Surface Protector.

SiOO:X is suitable for many common species including Larch, Cedar, various hardwoods, and certain modified woods e.g. thermally modified pine.  Please contact our sales team for further information on species suitability.

For use in external above ground conditions; timber cladding or decking should be selected for its natural durability with minimum durability Class 3 (according to BSEN 503-2). SiOO:X is not recommended for application on windows / doors.

The SiOO:X End Grain Sealer is available in 1 litre tubs.
