Singapore’s tropical weather can be unforgiving on painted walls. The mix of high humidity, frequent rain, and constant heat means moisture is always trying to sneak in. Before long, you start seeing damp patches, peeling paint, mould growth, and that white, powdery residue known as efflorescence. Ordinary paints just can’t keep up with these conditions for long. That’s why Berger Hydrolock Paint is a game-changer. Formulated for Singapore’s unique climate, it locks out water while letting walls breathe naturally. The finish stays smooth, vibrant, and durable even after months of heat and rain. For those looking for reliable waterproof paints in Singapore, Hydrolock offers the protection your walls deserve.
Hydrolock Paint is a high-performance waterproofing paint solution created to protect walls from Singapore’s humid, rain-heavy climate. It forms a strong, flexible coating that repels water and blocks moisture from seeping in, keeping surfaces dry and resistant to stains, cracks, and mould. The result is cleaner, healthier walls that stay beautiful for longer.
This paint is formulated with advanced polymer technology that creates a hydrophobic, water-repelling barrier. It contains fine polymeric fibres, just 1–3 mm in size, which form a mesh-like structure that is not visible to the naked eye. This fine mesh strengthens the paint film, providing reliable protection against water seepage on walls.
It can be applied to concrete, plaster, cement render, or masonry, making it versatile for both interior and exterior projects. Durable, protective, and stylish, it’s a long-lasting, waterproof paint designed to keep your walls looking fresh and strong year after year.
Hydrolock Paint creates a tough, water-resistant film that prevents moisture from seeping into the wall surface. This barrier protects against water damage, damp patches, and structural weakening caused by Singapore’s humid and rainy weather, helping walls stay dry and durable for years.
Unlike conventional waterproof coatings that trap moisture, Hydrolock Paint allows walls to breathe naturally. It keeps external water out while letting internal moisture escape, which prevents bubbling, peeling, and blistering that can shorten the life of the paint.
The paint contains fine polymeric fibres that form a mesh-like structure within the coating. This hidden reinforcement strengthens the paint film, adds flexibility, and allows it to handle minor cracks and temperature changes without losing adhesion or protection.
In Singapore’s high humidity, walls are often affected by mould and algae. Hydrolock Paint includes special additives that resist fungal and algal growth, helping walls remain cleaner, fresher, and more hygienic over time.
The paint bonds firmly to surfaces such as concrete, plaster, and masonry. Its flexible composition allows it to expand and contract with changes in temperature, preventing cracks, flaking, and surface wear.
Because Hydrolock Paint resists common wall problems and lasts longer, it reduces the need for frequent repainting and repair. This makes it a practical and cost-effective choice for anyone who wants walls that stay beautiful and protected with minimal effort.
To achieve the best waterproofing performance and durability from Berger Hydrolock Paint, correct surface preparation and application are essential. This system works as both a primer and a sealer, ensuring superior adhesion and long-term protection. Follow these steps for a professional-quality finish that lasts.
Start with a clean, dry, and stable surface. Remove all loose paint, dust, dirt, grease, algae, or fungal growth using a wire brush or water jet. For stubborn stains or biological growth, use a mild detergent or fungicidal wash. Allow the wall to dry completely before applying any paint. Moisture or contaminants left behind can weaken adhesion and reduce the waterproofing performance.
Inspect walls for cracks, holes, or uneven patches. Fill gaps and cracks up to 5 mm wide using a high-quality exterior-grade crack filler or polymer-based putty. For larger cracks, use a flexible sealant. After filling, sand the surface lightly to achieve an even, smooth finish. This ensures a uniform paint film and stronger bonding.
Hydrolock Paint acts as both a primer and a sealer, enhancing adhesion and waterproofing from the very first layer. Dilute the paint with up to 10% clean water (if recommended by Berger Paints) and mix thoroughly. Apply one coat evenly using a brush, roller, or spray. Allow it to dry for about 4 to 6 hours, depending on humidity and temperature. This first coat seals pores and prepares the surface for the final finish.
Once the primer coat is dry, apply the second coat undiluted for optimum strength. For highly exposed or weather-prone walls, a third coat can be applied for extra durability. Maintain a consistent film thickness and ensure complete coverage, especially on corners and ledges where water tends to collect. Allow each coat to dry fully before applying the next.
After the final coat, protect the surface from direct water contact for at least 48 hours. This curing period allows the acrylic film to harden completely, forming a flexible, water-repelling layer that resists moisture ingress. Once cured, the coating will develop its full protective strength.
6. Regular Inspection and Maintenance
For lasting results, inspect painted walls periodically, especially after heavy rain. Clean surfaces occasionally with mild water to remove dust or pollutants. Touch up minor cracks or damaged areas promptly using the same paint to maintain consistent waterproofing performance.
With Singapore’s challenging weather, keeping walls strong and spotless requires more than just paint; it needs protection that performs. Berger Hydrolock Paint delivers exactly that, combining advanced waterproofing science with lasting beauty. It shields walls from moisture, resists mould and peeling, and ensures every coat stands up to the heat, humidity, and rain. Visit Berger Paints Singapore today!
