Porcelain Fixing Products

Installing Porcelain paving looks at first glance to be as simple as laying any other paving.

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

About

Priming Slurry is designed to facilitate a strong bond between low porousity porcelain and natural stone paving tiles and the bedding mortar mix.

The use of a slurry primer is essencial when laying porcelain patio tiles to ensure the tiles remain perminantly fixed and don't become loose.

Pavestone strongly reccommends using Slurry Primer to prime all 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 as well as enhancing the bonding.

A polymer modified, cement based, slurry primer, specifically designed to meet the recommended performance characteristics of BS7533.

 

Usage

Simply add water as instructed and mix to produce a high quality priming slurry.

Brush primer slurry on the underside of each paving tile/slab just before laying. It's easy to apply and doen't add excessive cost to the installation.

Coverage

Packed in a 25kg multi-wall paper sack

One 25 kg bag of Slurry Primer mixed with water will cover approximately 19m2 of paving tiles/flags.

 

About

SBR Bond is a synthetic, rubber polymer, emulsion cement additive that improves the flexural & tensile strength and ensures a strong bond between low porousity porcelain / natural stone paving tiles and the bedding mortar.

SBR also reduces mortar shrinkage and water permeability when added to a mortar mix.

If you do not have access to a Slurry Primer premix then you will need to make your own using SBR Bond.

Usage

To make a slurry primer or 'bonding bridge': Mix to a smooth creamy consistency with ordinary Portland Cement. The approximate mix is 1 part SBR: 1 part water: 5 parts cement (by volume). i.e. 25kg cement & 1 tub SBR & water.

Brush the primer slurry on the underside of each paving tile/slab just before laying.


Coverage

Packed in a 5 litre container.

Dilute SBR Bonding Additive with an equal volume of water.

One 5 litre container is sufficient to cover 30m2 of paving tiles/flags.
