Frequently Ask Questions

The coating lasts between 15 to 20 years. The exact time depends on factors like the product's quality, how it's applied and the weather. Good preparation and application are key for longevity. Regular cleaning and resealing will also help.

 
 
 

The best coating for an asphalt roof is an advanced liquid coating. It is a flexible, cold liquid applied, seamless polyester methacrylate waterproofing system which is ideally suited for long term waterproofing of flat roofs. The system has low -odour making it the ideal waterproofing system for sensitive areas such as schools and hospitals. It protects against UV rays, weathering and other factors. They can extend the lifespan of your old asphalt roof or balcony by adding an extra layer of protection.

The number of coats of waterproofing you need depends on the surface type and the product you use. Most waterproofing products recommend applying at least two coats. This gives the best protection. But, some products may need more coats for better coverage or durability.

The best time to waterproof depends on the weather and the area's needs. Ideally, it is best to waterproof in dry seasons. This is when there is little rainfall or moisture. This ensures that the waterproofing materials have time to cure and stick to the surface. They give long-lasting protection against water damage.

A liquid coating is a protective layer. It is applied to a surface as a liquid. Then, it dries or cures to form a solid film coating. They can be made from various materials. These include paints, varnishes, lacquers, and epoxies. They protect against corrosion, weathering, abrasion and chemicals.

Yes, you can waterproof over an old membrane. But, only if the old membrane is in good shape and well prepared. Before adding new waterproofing, clean and inspect the old membrane. This ensures there is no damage or rot. Make any needed repairs first. Then, apply the new waterproofing.

If it rains after waterproofing, the treatment should prevent water from seeping in. Waterproofing products create a protective barrier that repels water and prevents moisture penetration. But, the waterproofing's effectiveness can vary. The quality of the product used and the preparation of the surface determine it.
