ESHA DESMOSEAL | Silane-based liquid-applied elastomeric waterproofing coating

- Excellent adhesion without primer to concrete, bricks, tiles, render, metals and plastics

- Dries very quickly without forming bubbles — forms a skin in 45–75 minutes

- Allows for spot repairs due to adhesion to itself

- Wind pressure resistance >50 kPa

⚠️ Restrictions:

- Requires a dry substrate — on damp surfaces, priming with PRIMER AQUA 2K is mandatory

- Not to be applied in rain, frost or at temperatures below 5°C

- Fire reaction class E — check against the fire protection design

- Resistance to plant roots: NPD — not specified, although the data sheet mentions planters

Roofs & outdoor areas

- Concrete flat roofs and terraces

- Surfaces with standing water

Hydraulic works

- Water tanks

Basements

- Basements and retaining walls

Green roofs

- Planters (note: root resistance is denoted as NPD — for a green roof with expected root growth, a separate root-barrier layer is required)

Special substrates

- Bricks, tiles, render, metals and plastics

System-level note:

The surface must be dry and cleaned with compressed air — cleaning with water should be avoided. Cracks must be filled with ESHAPOLYSEAL 1K. On concrete, PRIMER PU or PRIMER AQUA 2K is recommended; on bituminous residues, ESHAPRIMER PUB 2K; and on a fresh substrate, PRIMER AQUA 2K is mandatory.

Apply cold using a roller or air spray gun in 2–3 cross-hatched coats, allowing at least 3 hours’ drying time between coats, with a thickness of ≤0.5 mm per coat. Thin with ESHADESMOTHINNER up to 10% by weight. For reinforcement, use ESHATERRA 50 or glass fibre mesh between coats. Curing time: 12 hours per 1 mm; final strength is achieved in 2–5 days.
