A key characteristic of porcelain is an exceptionally low water absorption value, meaning that the paving tile will not draw moisture to the same degree as other paving materials. This is a great benefit when it come to the surface resisting staining and staying looking clean. However, this also means that porcelain paving will absorb almost nothing from the bedding mortar and concequently, without help, porcelain will not form a strong, sustainable bond to the mortar bed.
Priming Slurry is designed to facilitate the strong bonding of non-pourous / low porous, porcelain and natural stone paving. To create the strong, sustainable bond required, brush primer slurry on the underside of each paving tile/slab just prior to laying. It's easy to apply and doen't add excessive cost to the installation.
Slurry Primer is not just for porcelain. We strongly reccommend using it to prime natural stone paving flags, just prior to laying, as it will significantly reduce the potential for 'picture frame' stains and patches from the cement in the base mortar being drawn up through to the face of the stone.
A polymer modified, cement based, slurry primer, specifically designed to meet the recommended performance characteristics of BS7533. Manufactured from a controlled blend of specially selected aggregates, cements, and synthetic polymers and only requires the addition of water to produce a high quality priming slurry for use to improve bond strengths of porcelain paving, natural stone setts and cobbles, flags, concrete and clay pavers.
