What Is Costar 2K Waterproofing Compound?

Costar 2K is a two-part waterproofing compound that combines a specially formulated cement-based powder with a polymer liquid additive. When mixed together, the two components create a waterproof coating that bonds strongly to concrete and masonry surfaces, preventing water ingress and protecting structures from dampness, leakage, and moisture damage.

The system is suitable for residential, commercial, industrial, and civil engineering projects, making it a reliable waterproofing solution for contractors, builders, engineers, architects, and property owners across Nigeria.

Why Choose Costar 2K Waterproofing Compound?

Waterproofing for Dampness Prevention in Buildings

Dampness is a common problem in Nigerian buildings due to groundwater, rainfall, poor drainage, and inadequate waterproofing during construction.

Common signs of dampness include:

• Peeling paint
• Mold growth
• Musty odors
• Wall discoloration
• Efflorescence
• Cracked plaster
• Structural moisture damage

Applying Costar 2K Waterproofing Compound helps create a protective barrier that prevents water penetration and keeps walls and concrete structures dry.

How Costar 2K Works

The 20kg powder component contains cement, graded fillers, and waterproofing additives, while the 8-litre liquid component contains polymer modifiers that improve flexibility, adhesion, and waterproof performance.

After mixing both components according to the manufacturer’s instructions, the compound is applied by brush, roller, or trowel in multiple coats. Once cured, it forms a seamless waterproof membrane that resists water penetration and protects the underlying structure.

Advantages for Contractors and Builders

Costar 2K is widely used by construction professionals because it offers:

• Easy site mixing
• Fast application
• Strong bonding
• Reliable waterproof performance
• Compatibility with cementitious substrates
• Reduced maintenance costs
• Improved building durability

It is an excellent waterproofing solution for residential housing projects, commercial buildings, industrial facilities, and infrastructure construction.
