When installing porcelain paving, achieving a secure, long-lasting bond is crucial. Porcelain slabs are low-porosity, which means they don’t naturally adhere well to mortar. Without a bonding layer, the patio can experience loose slabs, movement, or even delamination over time. A slurry primer for porcelain acts as a bonding agent between the paving slab and the mortar bed. This creates a strong adhesive layer that prevents lifting and ensures your patio remains durable and visually appealing.
Why Porcelain Patios Need Slurry Primer
Porcelain is highly durable and stylish, making it a popular choice for patios. However, its non-porous nature requires extra care during installation. Skipping a slurry primer for porcelain can result in:
Slabs lifting or rocking after freeze-thaw cycles.
Bond failure between the mortar and the slab.
Water ingress and potential weed growth in weak joints.
Ensures adherence to BS 7533 (British Paving Standards)
Applying a slurry primer for porcelain, such as Joint-It Slurry Primer, guarantees a strong, lasting bond that protects your investment.
