Protect wall surfaces with a two-component damp-proofing plaster
Its special two-component formula creates an effective damp barrier on damp and moisture-affected wall surfaces. Ideal for repairing and protecting wall surfaces after injection treatment. It can be used in both under-plaster and top-coat applications.

Yes, HydroFix is specifically designed to be applied to damp surfaces. A matt-damp surface actually improves adhesion performance. However, on surfaces with active water flow, a water-stopping treatment must be carried out first.
At least 2 coats are applied. Each coat is 2 – 2.5 mm thick and the total should be 3 – 4 mm (3 mm recommended). The waiting time between coats is 6 – 8 hours.
Yes, but the choice of paint is not free. Once the render is visibly dry (at least 3 days), use only breathable (water-vapour-permeable) silicate or silicone emulsion paints. Plastic/acrylic-based paint must not be applied over HydroFix — it blocks vapour transfer, moisture builds up behind the plaster, salt crystallises and the layer blisters within a few months.
