What is a cementitious slurry grout?

A cementitious slurry grout is a flowable grout mixed with water and spread across paving. It fills joints fully and is designed for non-permeable projects using, porcelain, other natural stone, or concrete pavers. Slurry grouts are ideal for projects requiring maximum durability, strength and efficient installation.

When should I use slurry grout instead of brush-in?

Use slurry grout for areas that need to withstand heavy loads or vehicle traffic, or where maximum joint strength is required. It provides stronger adhesion and better long-term performance than brush-in options. Designed for impermeable bedding, if joints need to be permeable, use a a brush-in, or an epoxy grout.

Is slurry grout suitable for porcelain paving?

Yes. Slurry grout is a great choice for porcelain paving, as long as you have an impermeable bed. As porcelain paving often has narrower joints, use a slurry grout designed for for reduced joint widths.

Do I need a primer before using slurry grout?

Yes. A slurry primer is always recommended and should be applied to the back of each slab before laying to ensure proper adhesion, prevent future movement and avoid issues with efflorescence.

How long does slurry grout take to cure?

Most slurry grouts set within a few hours and achieve full cure within 24–48 hours, depending on temperature and conditions. Avoid heavy traffic until the grout is fully cured.

How do I prevent staining when using slurry grout?

Pre-seal porous stone before grouting, avoid working in hot conditions, and clean residue promptly using clean water or a suitable grout haze remover.
