For leaking showers, balconies, and tiled wet areas where lifting tiles is not an option, Showerseal Sealer penetrative treatment seals porous substrates from within. This clear siloxane/silane solution penetrates deep below the surface to create an internal hydrophobic barrier, stopping water ingress and reducing efflorescence without altering the original appearance or gloss of the tiles and grout.
The siloxane/silane chemistry works by lining the internal pores of the substrate rather than forming a surface film. This subsurface barrier resists high pH conditions, making it compatible with new concrete, sand and cement beds, and lime-based mortars. Because it does not block the pores completely, the treated substrate retains its breathing ability, allowing moisture vapour to diffuse out of the structure. On glazed tiled areas, the liquid penetrates exclusively through the porous grout lines.
Showerseal Sealer is suitable for porous substrates, including:
Surfaces must be structurally sound, dry, clean, and free of dust, oils, grease, curing compounds, surface water, or continual dampness. Apply Showerseal Sealer by brush, roller, or spray, ensuring the substrate is thoroughly saturated. For walls, start spraying at the top and work down to allow the liquid to run evenly and saturate the surface. At 25°C and 50% Relative Humidity, individual coats are touch dry in 2 to 4 hours and set in 4 to 8 hours. Full cure is achieved 24 to 48 hours after the final coat is applied.
Yes, Adheseal Showerseal penetrates porous surfaces to form a hydrophobic barrier, inhibiting water ingress without requiring tile removal. This offers an economic solution to sealing leaks in tiled areas.
No, Showerseal dries clear with no or low gloss, maintaining the original appearance of the surface. It works by creating a barrier inside the substrate, not on top of it.
No, Adheseal Showerseal is a penetrative sealer, not a filler. It cannot bridge existing cracks or fill voids. Loose or cracked grout should be replaced before application.
The shower recess can typically be used 24 to 48 hours after applying the final coat. This allows sufficient time for the product to fully cure and establish the hydrophobic barrier.
| Application | Key benefit | Primary trades |
|---|---|---|
| Treating leaking tiled showers and wet areas | Seals water leaks by creating an internal hydrophobic barrier without the cost and disruption of tile removal. | Plumbers, Tilers, Renovators |
| Protecting external concrete, render, brick, and block walls | Makes porous surfaces hydrophobic, inhibiting water ingress and reducing the risk of efflorescence. | Builders, Landscapers, Property Maintenance |
| Sealing porous pavers and stone | Provides long-lasting water protection without altering the surface appearance or creating a gloss finish. | Landscapers, Tilers |
| Hydrophobic treatment for porous FC sheeting and painted surfaces | Inhibits water absorption while allowing the substrate to breathe, extending surface life. | Painters, Property Maintenance |
Ensure the surface is completely clean, dry, and sound. For showers, stop use for 48 hours prior. Remove any loose grout, oils, or soap scum. Old sealants must be removed and the joint cleaned to ensure proper penetration.
Apply using a brush, roller, or low-pressure sprayer. It is essential to fully saturate the substrate.
Apply 3 soaking coats, focusing on the grout lines. 250ml to 500ml is typically sufficient for a standard shower.
Start at the top and work down, allowing the liquid to run evenly down the wall to ensure complete saturation.
Allow the final coat to cure. The area can typically return to service after 24 to 48 hours. Any new sealant can be applied after the Showerseal has fully dried. Immediately wipe any liquid product off glass or glazed surfaces to prevent etching.
This material is classified as a Dangerous Good, Class 3, due to its flammability. Always ensure adequate ventilation and eliminate ignition sources when handling.
Wear rubber boots, overalls, gloves, safety glasses, and a respirator. If inhalation risk exists, use an organic vapour/particulate respirator meeting AS/NZS 1715 and AS/NZS 1716 standards.
Use only in well-ventilated areas, preferably outdoors. Ensure adequate ventilation to maintain air concentrations below exposure standards. Avoid working in confined spaces without checking the atmosphere.
Store in a cool, dry place, away from all ignition sources. Keep containers securely sealed and locked up. Plastic containers must be approved for flammable liquids. Ventilate sealed containers periodically to prevent pressure build-up. Shelf life is up to 12 months in unopened containers. Dispose of contents and containers according to local regulations.
Proper substrate preparation is critical for Adheseal Showerseal to penetrate effectively and form a lasting hydrophobic barrier.
Surface prep: Ensure surfaces are structurally sound, stable, dry, and clean. Remove all dust, loose material, oils, grease, and other contaminants that may prevent absorption. Concrete must be cured for at least 28 days. Loose or cracked grout and old sealants must be replaced and allowed to dry completely before application.
Primer: Not required. Adheseal Showerseal is designed to penetrate directly into porous substrates.
Surface prep: Surface must be dry, clean, and free of flaking or friable paint. Ensure the painted surface is porous enough to allow penetration. Conduct a test area to confirm absorption and compatibility.
Primer: Not required. Adheseal Showerseal penetrates suitable painted surfaces.
