Damp is one of the most stubborn and damaging problems a South African homeowner or contractor can face. Left untreated, rising and penetrating damp causes mould, mildew, efflorescence and peeling paint. The longer it goes unaddressed, the more expensive the repair. Cue Plascon’s Water-based DampSEAL: a purpose-built solution designed to stop damp in its tracks, while offering retailers a high-performance addition to a growing waterproofing category.

At the heart of Water-based DampSEAL’s performance

Water-based DampSEAL is a water-based acrylic emulsion coating formulated specifically to treat the effects of rising and penetrating damp on interior and exterior vertical cement plaster and concrete walls. What sets it apart is its high moisture tolerance. Water-based DampSEAL adheres effectively to surfaces with up to 60% moisture content, so it can be applied to damp surfaces without waiting for them to dry completely. 

Once applied, Water-based DampSEAL forms a barrier that protects against rising damp, prevents mould, mildew, and efflorescence (the white, chalky salt deposits that appear on walls as moisture moves through them), and stops peeling paint, which often signals an underlying damp problem. No primer or undercoat is required on a fresh substrate, and it can also be applied directly over previously painted surfaces that have been properly cleaned, making it a clear-cut solution for both DIY homeowners and professional contractors.

Easy to apply

Water-based DampSEAL is applied by brush or roller in two coats. The first coat is thinned with 10% water by volume; the second coat is applied as is, with 4 to 6 hours drying time between coats. The two-coat system is designed to achieve a minimum dry-film thickness of 100 microns. This is the critical threshold at which the coating forms a consistent, effective moisture barrier across the treated surface. Once fully dry, the treated surface can be overcoated with a Plascon decorative interior or exterior product of choice.
