Description  

Adheseal Showerseal is a clear penetrating water-repellent treatment for porous grout, masonry and compatible tiled wet-area surfaces. It soaks into sound, absorbent material rather than leaving a visible coating on top, helping reduce water absorption without changing the appearance of the finished surface.

Showerseal can be useful for treating porous grout in an otherwise sound tiled shower, bathroom or laundry, and for suitable exterior tiled areas and masonry. On glazed tiles, the treatment works through porous grout or adjacent absorbent surfaces rather than penetrating the glaze itself.

When to choose Showerseal

  • Reducing water absorption through sound, porous grout in a tiled shower or wet area.
  • Water-repellent treatment of suitable porous masonry and grout on tiled balconies or terraces.
  • Treating compatible porous surfaces where a clear, non-film-forming finish is preferred.

What Showerseal cannot fix

This is a penetrating sealer, not a replacement waterproofing membrane. It cannot bridge cracks, repair loose grout, seal open joints or correct a failed shower membrane. If water is entering through a construction defect, cracked grout or damaged waterproofing, the underlying problem needs repair before treatment.

Clean and thoroughly dry the surface, repair defective grout and joints, then apply the recommended treatment coats with adequate penetration and curing time. Wipe any excess from glazed tile and glass promptly. Confirm the suitability of the surface and the complete wet-area system before use.

Common Questions  

How much Showerseal is needed for a typical shower?
About 250–500ml applied in 3 soaking coats.

What coverage should I allow?
About 5m² per litre, depending on the substrate porosity.

Can Showerseal fix cracked grout?
No. Cracks, loose grout and voids must be repaired before treatment.

How long should the shower stay dry?
Keep it dry for about 48 hours before treatment and at least 24 hours after the final coat.

Uses & Benefits  
Clear silane/siloxane penetrative treatment for leaking showers, balconies and porous tiled wet areas. Creates a hydrophobic barrier within porous grout, masonry and mineral surfaces without forming a visible surface film. Typical coverage is about 5m² per litre, depending on porosity. A typical shower uses about 250–500ml applied in 3 soaking coats. The treated surface remains vapour-permeable.
How To Apply  
Keep the area dry for about 48 hours before treatment so the porous substrate can absorb the sealer. Prepare surfaces so they are sound, dry, clean and free from dust, oils, grease and continual dampness. Apply by brush, roller or spray until the porous areas are thoroughly saturated. For shower recesses, apply 3 soaking coats as specified by the product guidance. At 25°C and 50% relative humidity, individual coats are touch dry in about 2–4 hours and set in about 4–8 hours. Keep the treated shower out of service for at least 24 hours after the final coat.
Limitations and Safety Info  
Does not bridge cracks or fill voids. Repair loose or cracked grout and mortar before treatment. Do not use on highly friable or sandy substrates that cannot develop an effective internal barrier. Wipe the liquid from glass and glazed surfaces immediately. Allow new concrete at least 28 days cure before treatment. Remove incompatible joint sealants before application and replace them only after the treatment has dried. Apply between 5°C and 30°C.
Suitable Substrates  
  • Porous grout joints in tiled showers and wet areas.
  • Concrete, brick, masonry and blockwork.
  • Cement render and fibre-cement sheet.
  • Sandstone and compatible porous stone.
  • External tiled decks, balconies and terraces through their porous joints and mineral surfaces.
