Description

Sika Damp Proofing Slurry is a low-odour, easy-to-use alternative to bitumen-based coatings for below-ground waterproofing. The powder is mixed with water only, with the water-to-powder ratio adjusted to achieve slurry consistency for brush application or a stiffer mortar for trowel application. It is applied in two coats, with the second coat applied at 90° to the first. One 25kg bag covers approximately 6.5–7.0m² at 2mm thickness.
