FAQs
Can I apply this product to my house's external painted walls?
No, this product is designed for porous masonry and stone. It is not suitable for use on painted surfaces as it may not adhere correctly or could damage the existing paint.
How long does the protection last?
Ronseal Thompson's One Coat Water Seal Ultra is designed to outlast conventional waterproofers, offering long-lasting protection. While specific longevity varies with environmental conditions, it typically provides effective protection for several years.
What is the difference between this and standard water sealers?
This product uses a silicone micro emulsion and is designed for one-coat application. It is also formulated to be highly water repellent and can be applied to damp surfaces, offering greater convenience and outlasting many standard treatments.
Can I apply this product over an existing sealer?
It is not recommended to apply this product over an existing sealer. For best results and to ensure proper adhesion and performance, remove any old sealers or coatings before application.
How do I clean up any spills?
Wipe up spills immediately with a damp cloth or sponge while the product is still wet. Dried spills may be difficult to remove. Clean tools with water.
Is this product safe for use near plants or vegetable gardens?
While the cured product is generally inert, it is best practice to avoid direct contact with plants and edible crops during application and drying. Protect surrounding vegetation with sheeting if necessary.
What are the ideal weather conditions for application?
The product can be applied to damp surfaces, but it should not be applied during heavy rain or if frost is expected within 24-48 hours of application, as this can affect curing and performance.
Troubleshooting
Product not beading water after application.
Ensure a sufficient amount was applied and that it penetrated the surface. Reapplication might be necessary if the surface is extremely porous or if the product was applied too thinly. Check that the surface was not already sealed or coated with a non-compatible material.
Uneven appearance or streaks after drying.
This can occur if the product was not applied evenly or if rain washed over it before it fully cured. Apply a second thin coat to even out the appearance, ensuring even coverage this time.
Surface remains visibly wet or dark after treatment.
This may indicate the surface is not sufficiently porous for the product to penetrate, or it has been over-applied. Allow more time for drying. If the issue persists, the surface may not be suitable for this type of treatment.
Moss or algae growth continues after application.
Ensure all existing moss and algae were thoroughly removed before application. Treat any regrowth with a suitable cleaner and reapply the water seal once the surface is clean and dry.

Setup, Compatibility & Care Instructions
Preparation is key for optimal results.
- Surface Check: Ensure the surface is clean, dry or damp, and free from loose debris, moss, or algae. Use a stiff brush or pressure washer to remove any contaminants. If treating a particularly dirty surface, allow it to dry before application.
- Application: Apply using a brush, roller, or sprayer. Work the product into any cracks or pores.
- Coverage: Apply generously and evenly to achieve a uniform finish. One coat is sufficient for protection.
- Drying: Allow the surface to dry fully. Drying times can vary based on temperature and humidity, typically taking 24 hours for full curing.
Compatibility:
- Suitable for use on most common porous masonry and stone surfaces, including brick, concrete, and paving slabs.
- *Not* suitable for use on treated wood, plastic, painted surfaces, or non-porous materials.
Care:
- The treated surface requires no special care beyond normal cleaning. Avoid abrasive cleaners that could damage the water-repellent barrier.
- The product is designed to be long-lasting, reducing the need for frequent reapplication. Monitor the surface annually and reapply if water no longer beads effectively.
