Crown Rain Protek | Waterproofing Paint in Kenya

Kenya’s weather can be tough on buildings. Heavy rainfall, intense sunlight and constant temperature changes can expose roofs, terraces and exterior walls to water damage, cracking and surface deterioration.

Crown Rain Protek is designed to provide a strong line of defence against these challenges. It is a high-performance, fibre-reinforced, elastomeric acrylic waterproof coating designed for exposed roofs and exterior walls. Once cured, it forms a flexible, breathable and UV-resistant waterproof membrane that helps protect surfaces from rain and weather-related damage. 

What Is Crown Rain Protek?

Crown Rain Protek is a liquid-applied acrylic waterproof coating formulated for demanding exterior applications. Its elastomeric properties allow the coating to accommodate normal expansion and contraction caused by temperature changes.

It can also bridge cracks of up to 2 mm, helping create a continuous protective layer over suitable surfaces. 

Unlike a conventional exterior coating that primarily focuses on appearance, Crown Rain Protek is engineered with waterproofing and surface protection as key functions.

Protect Your Home Against Rain Damage

Water penetration can gradually cause serious problems in buildings. Repeated exposure to rain can contribute to damp surfaces, deterioration of exterior finishes and damage to concrete and masonry.

Crown Rain Protek creates a water-resistant barrier on roofs, terraces and exterior walls, helping prevent rainwater from penetrating treated surfaces. 

This makes it particularly useful for Kenyan properties exposed to seasonal heavy rainfall.

Key Benefits of Crown Rain Protek

1. Excellent Water Resistance

Crown Rain Protek forms a protective membrane that provides an effective barrier against water on roofs, terraces and exterior walls. 

2. Crack Bridging up to 2 mm

Buildings naturally experience movement due to temperature changes. Crown Rain Protek has crack-bridging capability of up to 2 mm, helping maintain protection across suitable minor cracks. 

3. UV Resistant

Constant exposure to sunlight can affect exterior coatings. Crown Rain Protek is formulated to resist UV degradation, helping maintain the performance of the waterproofing membrane over time. 

4. Flexible and Elastomeric

The coating provides excellent flexibility and elongation, allowing it to accommodate normal expansion and contraction stresses associated with temperature variations. 

5. Antifungal Protection

Crown Rain Protek has antifungal properties, providing an additional layer of protection for treated surfaces. 

6. Tough and Abrasion Resistant

After curing, the coating forms a tough, durable and abrasion-resistant membrane. It is also suitable for light foot traffic in appropriate applications. 

7. Water-Based and Low VOC

Crown Rain Protek is a non-toxic, water-based waterproofing system that is free from heavy metals and has low VOC content. 

Where Can Crown Rain Protek Be Used?

Crown Rain Protek is suitable for a wide range of exterior waterproofing applications, including:

• Building roofs
• Roof slabs
• Terraces
• Parapets
• Sunshades
• Podiums
• Exterior walls
• Old concrete surfaces
• Mosaic tiles
• Wooden roofs
• Domes
• Concrete and masonry surfaces 

This makes Crown Rain Protek a versatile solution for homeowners, contractors, property developers and building maintenance teams looking to protect exposed surfaces from rain and weather damage.

Crown Rain Protek for Roof Waterproofing

Roofs receive some of the highest exposure to rain and sunlight. Small cracks, ageing surfaces and repeated thermal movement can eventually create opportunities for water penetration.

Crown Rain Protek can be applied as part of a roof waterproofing system on suitable new or existing roof surfaces. The application system involves appropriate surface preparation and multiple coats to achieve the specified film thickness and performance. 

For larger roof areas, Crown recommends the use of reinforcing fibreglass mesh between coats for additional protection where specified. 

Crown Rain Protek for Exterior Walls

Exterior walls are also vulnerable to driving rain and moisture penetration. Crown Rain Protek can be used on suitable exterior vertical surfaces to create a protective waterproofing layer.

For new construction and repainting or repair applications, the product has specific dilution, coverage and recoating requirements that should be followed according to Crown Paints' technical instructions. 

Proper Surface Preparation Matters

The effectiveness of any waterproofing coating depends heavily on correct preparation and application.

Before applying Crown Rain Protek, the surface should be properly assessed, cleaned and prepared. Damaged areas and suitable non-structural cracks should be addressed before coating.

The product can be applied to damp backgrounds, but not to surfaces covered with standing or surface water. 

Following the recommended application procedure helps ensure that the coating achieves the intended performance.

Why Choose Crown Rain Protek?

Crown Rain Protek combines waterproofing performance, flexibility, UV resistance and antifungal protection in one coating system.

For Kenyan buildings exposed to heavy rain and intense sunlight, it provides a practical way to help protect roofs, terraces and exterior walls while supporting the long-term durability of the underlying surface.

Don't wait for rain damage to become an expensive repair. Protect your surfaces with Crown Rain Protek.
