Waterproof Coating Services
Stop leaks at the source — roofs, walls, balconies, bathrooms and rooftops.
Professional waterproof coating across the Klang Valley
Water ingress causes peeling paint, mould and structural damage. Our waterproofing membranes and coatings protect rooftops, balconies, bathrooms and external walls from leaks.
What we paint
Our waterproof coating service covers the following surfaces across homes, offices and commercial premises in Kuala Lumpur and Selangor:
Surface preparation
Proper preparation is what makes a finish last in the Malaysian climate. Before any paint goes on, we carry out the following:
- Cleaning the substrate and removing existing failed coatings
- Crack chasing and routing of structural cracks for proper sealing
- Repairing spalled concrete and rebuilding damaged substrates
- Treating active leaks with crack injection where required
- Priming the substrate to ensure membrane adhesion
Our process
Every waterproof coating project follows a structured process from first inspection to warranty handover:
- 1Inspection to locate the source of water ingress, not just the visible symptom
- 2Surface preparation — cleaning, crack routing and concrete repair
- 3Primer coat suited to the substrate and membrane system
- 4Application of the waterproofing membrane to the specified thickness
- 5Reinforcement of corners, joints and penetration points
- 6Cure time and, where applicable, a water-test to confirm the seal
Materials & coating systems
We apply liquid-applied polyurethane and cementitious waterproofing membranes, with reinforcement fabric at corners and joints. Systems are selected based on the surface, exposure and movement expected.
Application method
Liquid membranes are applied by roller and squeegee in multiple passes to build the required film thickness, with fabric reinforcement embedded at joints, corners and cracks. Each layer is allowed to cure before the next is applied.
Property types we paint
What affects the cost
- Area to be waterproofed and accessibility
- Extent of existing damage and concrete repair needed
- Type of membrane system specified
- Number of reinforcement layers at joints and corners
- Whether a protective top coat or screed is required over the membrane

Frequently asked questions
Water often travels from the entry point before showing as a stain, so the visible damp is not always the source. Our inspection traces the likely entry point and we quote to treat the cause, not just cover the symptom.
