Water Block
A silicone, water-based, invisible quick-drying sealer for all natural stone — including slate, sandstone, travertine, marble and quartz.
Key benefits
- Silicone, water-based formula
- Invisible, quick-drying finish
- For slate, sandstone, travertine, marble & quartz
- Ideal for fast spray application
Directions for use
- 01 Ensure the surface is free of loose particles, dust & flaking material.
- 02 Apply by domestic spray for a continuous film — a spray bottle works best.
- 03 On tiles and sandstone cladding, apply with a spray bottle or spray pump — it secures even coverage.
- 04 Saturate the surface evenly and leave to dry.
- 05 Thoroughly inspect and seal all pin-holes & surface imperfections.
- 06 Apply evenly — sealer applied poorly can leave a white residue once it dries.
Where it's used
Concrete, plaster, brickwork, concrete aprons, paving, retaining walls, concrete flooring, parapet walls, clay & cement roof tiles, and grouting between tiles.
