Brush-In Jointing Compounds FAQ

Can I use a pressure washer on resin grout joints?
Pressure washing resin grout joints is generally not recommended. Resin grout is more delicate and high-pressure water can dislodge or erode it, leading to gaps or damage. Instead, use:

• A soft brush or scrubbing pad with mild detergent

• Low-pressure water (garden hose) for rinsing

• Specific grout stain removers, following manufacturer instructions
  Always test cleaning methods on a small area first.

Is brush-in grout suitable for sandstone slabs?
Yes, brush-in grout can be suitable if:

• Joint widths are narrow (up to 6mm)

• Sandstone slabs are properly sealed to prevent staining

• The grout chosen is compatible with sandstone and outdoor use
  Consult manufacturers or professionals to pick the best product and ensure correct application and maintenance.

Does brush-in resin grout set solid?
Yes, brush-in resin grout cures to a solid but slightly flexible state. It:

• Begins setting within hours; full cure takes 24–48+ hours

• Offers flexibility to accommodate movement without cracking

• Provides strength and stability once cured

• Resists water and weathering for durability
  Follow manufacturer mixing and curing guidelines for best results.
