Previously, paving slabs & blocks would be laid directly onto a bedding mortar but without the use of a primer slurry, this method could result in costly and high profile failures. By priming your slabs and blocks with Pro-Prime Slurry, you can help to eliminate this.
Pro-Prime Slurry is also essential when laying porcelain paving because due to the non-porous nature of porcelain, it will not bond to the mortar bed. Pro-Prime Slurry has a unique blend that enables it to adhere to porcelain and create the required bond with the mortar bed.
Simply mix 7 litres of water per bag and mix for 3-5 minutes until smooth.
We recommend using a brush to apply the Pro-Prime Slurry Primer to the underside of your paving slabs/blocks at a thickness of 1mm-2mm immediately before laying onto the mortar bed.
