Sioo:x uses nature to form a silicon based shell on exterior timber, which weathers to a beautiful silver grey. Sioo:x End Grain Sealer is designed as part of the Sioo:x system to assist with better weathering of timber, by stopping excessive moisture ingress up the timber end grain.
Sioo:x is a two step process - this means you will need to coat the wood with one coat of Sioo:x "Step One" followed by one coat of Sioo:x "Step Two". Non-exposed ends (e.g. under flashings) can be treated with Step Two only.
Approximate coverage 4-5 m2 /L for the first coat Step One, 6-8 m2 /L for the second coat of Step Two (timber end grains absorb more than faces, tight grain timbers may have lower coverage rates).
