Ultra-Block™ is an economical water based specialty sealer formulated for six sided, dip-sealing, underside & pre-grouting sealing. Helps resist staining caused by water soluble minerals (including picture framing effect) which are normally absorbed through the back of the stone during installation. It also helps resist ef orescence migration & adhesive blotch marks. Can also be used as a pre-grouting sealer. Allows moisture vapour transmission (MVT).
NOTE: For high traffic, commercial or food areas or where premium performance / stain resistance is required – for a natural look use AQUA-SEAL GOLD+ and for a colour enhanced, enriched look use ENHANCE’N’SEAL.
Stone Gel+ for cleaning & disinfecting vertical surfaces;
ReFresh+ for food surface area cleaning and disinfecting;
IMPORTANT NOTE: TREAT THE SEALED UNDERSIDE SURFACE AS LOW POROSITY Ultra-Block™ will reduce the porosity of the underside sealed surface. Please contact your adhesive supplier or manufacturer for specifcation of the appropriate adhesive suitable for installing low porosity/dense surfaces. Sealed underside surface and substrate should be thoroughly wet out with the adhesive (back butter using the flat side of trowel) prior to applying adhesive with appropriate notch trowel to ensure proper coverage and adhesion. Follow adhesive manufacturer recommendation for the appropriate adhesive & ensure relevant Standards for stone & tile installation are followed.
