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).
USE: For porous surfaces e.g. all natural stone like basalt, bluestone, granite, limestone, marble, quartzite, sandstone, slate, travertine etc plus encaustic tiles, terrazzo, concrete, pavers, saltillo, grout and other surfaces.
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.
