Heavy rains, humidity, and moisture are inevitable challenges—especially in regions like Nairobi, Mombasa, and other parts of Kenya.

Rangi Paint Store now carries this high-performance product, making it easy for homeowners, contractors, and DIY enthusiasts to get top-tier waterproofing.

What Exactly Is Crown Rain Protek?
Crown Rain Protek is a fiber-reinforced waterproofing paint developed by Crown Paints. It forms a thick, flexible, and resilient coating that resists water penetration, makes surfaces weather-proof, and protects against dampness, peeling, and cracking.
Unlike ordinary exterior paints, Rain Protek is formulated to perform in extreme conditions. Its fiber-reinforcement helps the coating maintain integrity under expansion, contraction, and exposure to UV, so it doesn’t crack or flake easily.
Typical surfaces for Crown Rain Protek include:
- Exterior walls (especially exposed walls facing rain)
- Roofs and parapets
- Terraces, balconies, slabs
- Areas prone to moisture or splash
When applied correctly, it becomes a durable barrier, sealing off vulnerable zones while allowing substrates to “breathe” (i.e. letting trapped moisture escape).
Key Benefits of Using Crown Rain Protek
- Superior Waterproof Protection
The primary job: stop water from penetrating. Rain Protek is engineered to resist rain, leaks, and dampness — reducing the risk of water damage. - Fiber-Reinforced Durability
Adding fibers to the mix gives the coating extra strength. It is more resistant to cracking, peeling, and physical stress compared to standard paints. - Weather and UV Resistance
It holds up under heavy sun, changing weather, and temperature variation — especially important in Kenya’s climate where rain and intense sun often alternate. - Strong Adhesion & Flexibility
It sticks well to masonry, concrete, and plastered surfaces, and can expand/contract with the substrate without losing integrity. - Cost Savings Over Time
Instead of repeated touch-ups and repairs, a good waterproof layer reduces maintenance costs, paint failure, and structural damage. - Aesthetic Finish
Besides its protective role, Rain Protek delivers a clean, uniform finish so your home still looks great.
How to Apply Crown Rain Protek — Best Practices & Tips
To ensure your Rain Protek coating performs optimally, follow these application guidelines:
- Surface Preparation
- Clean the surface thoroughly: remove dust, loose plaster, flaking paint, algae, mold, or grease.
- Repair cracks, spalling, holes, or structural damage before applying.
- Allow the surface to fully dry.
- Priming
In some cases, especially porous surfaces, a primer or bonding coat may help with adhesion. - Mixing
Stir the Rain Protek paint well before use (even if it’s pre-mixed). Ensure fibers are evenly dispersed. - Application
- Use a brush, roller, or suitable spray equipment.
- Apply at least two to three coats, ensuring each coat is fully dry before applying the next.
- Maintain a wet edge to avoid lap lines.
- Avoid applying in direct midday sun or heavy wind conditions (to prevent premature drying).
- Curing & Drying
Let it cure properly. Avoid exposure to heavy rain immediately after application. Check product datasheet (or instructions from Rangi) for recoat time, curing schedule, etc. - Maintenance
Inspect periodically, especially after heavy storms. Touch up minor damage promptly to preserve integrity.

Addressing Common Questions & Concerns
Yes — it’s designed for harsh weather, including heavy rains and strong sun. The fiber reinforcement helps resist cracking under temperature fluctuations.
With proper application and maintenance, it can last many years. But periodic inspections (every few years) are wise, especially after extreme weather.
In most cases, yes — once the waterproof layer is stable and the surface is sound, you can apply compatible decorative paints. But check compatibility.
Rain Protek is formulated for exterior, high-moisture, exposed surfaces. For indoor walls, standard interior paints are often more suitable.
Avoid applying when rain is imminent. The coating needs time to cure/dry before being exposed to moisture.
Repair the damaged area (clean, fill crack, prime) and reapply Rain Protek to maintain the waterproof barrier.
Sample Use Case – Home in Nairobi
Imagine a homeowner in Nairobi’s high-rainfall neighborhood. After several rainy seasons, the exterior walls have begun to show damp patches, peeling paint, and even small cracks. Instead of repeatedly repainting with conventional masonry paint (which fails after one or two seasons), the homeowner chooses Crown Rain Protek via Rangi Paint Store.
- The walls are prepped and cleaned.
- Rain Protek is applied in 3 coats.
- Over the next 5+ years, the house remains dry, clean, and maintenance is minimal.
- When occasional touch-ups are needed, Rangi provides matching materials and technical advice.
This saves money, preserves structural integrity, and ensures peace of mind.
