Product Information

Full details

The Raincheck Universal Water Seal Kit is designed for homeowners and DIY enthusiasts looking to protect brick, concrete, stone, and timber surfaces from water damage. Its key benefit is creating a breathable, colourless barrier that repels water, preventing penetrating damp and moisture ingress, thus extending the life of your building materials. A potential caveat is that it is not suitable for surfaces containing salts or dense, low-porosity materials like pure limestone, for which a specific alternative product is recommended. This kit includes a 5L container of Raincheck Universal Water Seal and a 5L pump-action sprayer, offering a comprehensive solution for waterproofing.

Extended Product Information

FAQs

How long does the protection last?

The protection is long-lasting, with potential to last up to 10 years, depending on environmental conditions and exposure.

Can I apply this over existing paint or sealant?

No, the surface must be free from paints, stains, or biological growth for the product to adhere and function effectively.

What is the coverage rate?

Each litre treats approximately 3.5 m² when applied in two coats. The 5L kit is sufficient to treat approximately 17.5 m².

Can I use Raincheck Universal Water Seal on my patio slabs?

Yes, it is suitable for concrete paving slabs to help repel water and reduce moss and algae growth, provided they are porous and clean.

When should I reapply the product?

Reapplication is generally not needed for up to 10 years. However, if you notice water starting to penetrate the surface again, it may be time for a refresh coat.

What temperature is ideal for application?

The product should be applied when temperatures are above 5 °C and in dry weather conditions.

Can this product be painted over?

The product is designed to form a water-repellent barrier and is not intended to be painted over. Its goal is to protect the substrate's appearance.

Troubleshooting

Product not spraying evenly

Check the sprayer nozzle for blockages and adjust the spray pattern. Ensure the product is well-mixed.

Surface still absorbing water after treatment

Verify that two coats were applied correctly and within the recommended timeframe. Ensure the surface was properly prepared and is porous. Reapplication may be necessary if coverage was inadequate or conditions were suboptimal during application.

White residue or marks on the surface

This can occur if the product is not fully dry or if applied over a surface with salts. Ensure adequate drying time and ventilation. Avoid application on salt-laden surfaces.

Sprayer not holding pressure

Check all seals and connections on the pump-action sprayer for leaks. Ensure the pump is functioning correctly.

Pros and Cons

Pros

  • Provides effective, long-lasting waterproofing for various porous building materials.
  • Maintains the natural look of surfaces due to its colourless formulation.
  • Breathable barrier prevents moisture trapping, which is crucial for building health.
  • The included sprayer simplifies application, especially for larger areas.
  • UV resistance ensures the protection is not degraded by sunlight.
  • Environmentally friendly water-based formulation.

Cons

  • Not suitable for dense or low-porosity materials like pure limestone.
  • Cannot be applied to surfaces with existing paints, stains, or biological growth.
  • Application requires specific temperature conditions (above 5°C) and dry weather.

  • Potential for incomplete coverage if surface preparation is inadequate.

Setup, Compatibility & Care

Preparation:

  1. Ensure surfaces are clean, dry, porous, and free from any paints, stains, or biological growth (like mould or algae). Any existing growth should be removed and the surface allowed to dry thoroughly.
  2. Do not apply in damp weather or when temperatures are below 5°C.

Application:

  1. Shake the Raincheck Universal Water Seal container well before use.
  2. Apply two coats using a brush, roller, or the included pump-action sprayer.
  3. The second coat should be applied while the first coat is still wet, ideally within 30 minutes.
  4. Ensure even coverage and avoid over-application.

Sprayer Use:

  1. Fill the 5L Safeguard Pump-Action Sprayer with the product according to the sprayer's instructions.
  2. Pressurize the sprayer by pumping the handle.
  3. Adjust the spray pattern as needed for your surface.
  4. Use the flexible hose for reaching difficult areas.

Compatibility:

  • Suitable for brick, concrete, stone, and timber.
  • Compatible with products from the NOPE CP, Roxil, and SoluGuard ranges.
  • Do Not Use on surfaces containing salts or on dense/low-porosity materials like pure limestone (use Raincheck LS instead).

Care:

  • Keep treated areas protected from rain until the product is fully dry (drying time may vary based on conditions).
  • Clean the sprayer thoroughly with water immediately after use to prevent blockages.
  • Store the product in a cool, dry place, away from direct sunlight and frost.
