End Grain Sealer 

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 including board ends. 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.

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 SiOO:X End Grain Sealer is available in 250 ml, 1 litre and 5 litre containers.
