Product FAQ

To apply SpECtite CW100 effectively, ensure the substrate is clean and free from contaminants. Damp the surface with a fine spray of water, removing any standing water. Mix the components thoroughly using a slow-speed electric drill with a spiral paddle until lump-free. Apply a minimum of two coats using a medium hard short bristle brush, trowel, or roller. The first coat should be between 0.5mm to 1.5mm thick, and the second coat should be applied once the first is set hard, typically after 3 hours at 25°C. Finish each coat in one direction, with the second coat at 90° to the first.

SpECtite CW100 can be applied to concrete, masonry, and surfaces of potable water containers, swimming pools, silos, and planter boxes, among others.

SpECtite CW100 typically does not require curing; however, in hot conditions with high air movement, protection against premature drying is essential.

The recommended thickness for SpECtite CW100 is 2mm on walls and 3mm on floors.

The pot life of SpECtite CW100 at 25°C is 45 minutes.

A complete mixed pack of SpECtite CW100 covers approximately 11.0m² at a thickness of 1.0 mm, depending on the substrate profile.
