White Sand Prime RC is a water-based acrylic bonding agent designed to improve adhesion between concrete substrates and cementitious repair or coating systems. It is formulated as a copolymer emulsion with strong bonding performance.
White Sand Prime RC is used as:
- A bonding agent for concrete repair mortars
- A primer for cementitious coatings and renders
- A surface treatment to reduce suction in porous substrates
- An adhesion enhancer on dense or smooth concrete surfaces
It is suitable for:
- Concrete surfaces
- Masonry substrates
- Cement-based repair areas
- Structural repair zones before applying repair mortars
It is widely used in construction, repair, and rehabilitation projects.
White Sand Prime RC works by:
- Penetrating the substrate surface
- Creating a bonding bridge layer
- Reducing water absorption (suction)
- Improving adhesion between old and new materials
This ensures strong mechanical and chemical bonding in repair systems.
Yes. It is a water-based product, meaning:
- Easy cleanup with water
- Low odor
- Free from harmful solvents
- Non-flammable
- Excellent bond strength
- Water resistance
- High coverage efficiency
- Easy application
- Eco-friendly formulation
- Compatible with cementitious systems
Yes. It is specifically designed to be applied before repair mortars to:
- Improve adhesion
- Prevent debonding
- Ensure long-term durability
It is commonly used prior to applying repair systems like structural mortars.
Typical application steps:
- Clean the surface (remove dust, oil, loose particles)
- Ensure the substrate is sound
- Apply using brush, roller, or spray
- Allow it to become tacky before applying repair material
Proper timing is important for optimal bonding performance.
“Tacky” means the primer is partially dry but still slightly sticky. Applying repair mortar at this stage ensures maximum adhesion between layers.
It is typically applied to prepared and slightly damp surfaces, but not on surfaces with standing water. Proper surface condition ensures optimal bonding.
Yes. It is commonly used in:
- Vertical surfaces
- Overhead concrete repairs
It enhances adhesion, preventing material sagging or detachment.
It is a single-component acrylic copolymer emulsion, supplied as a milky white liquid.
