Pool coating —
decorative, elastic, long-lasting

Fully drain the pool, let dry — at least 7 days in sunny weather, longer if cloudy. Use a pressure washer to remove algae, limescale and old coating residue. Mechanically loosen any peeling areas, close cracks > 1 mm with concrete repair mortar and let cure for 7 days.

For old, defective coating we recommend removing completely down to solid concrete — half measures ruin the result.

Pro tip: Have the residual moisture of the pool concrete measured with the carbide method — moisture below 4 % is essential, otherwise layers come off later under water pressure.

Pool concrete is highly absorbent after cleaning. Apply deep primer, let dry for 24 h. This reduces first-coat consumption and significantly improves adhesion. For pools with old, defective coating, strip down to concrete first, then prime.

Apply deep primer thinly — a thick coat forms glossy spots that later fail under water pressure.

Pro tip: On very porous or cracked pool concrete: first apply a repair-mortar slurry as an equaliser, then deep primer — you get a perfectly prepared surface.

Diluted with up to 5 % water (up to 10 % with airless sprayer). Brush and lambswool roller. Consumption 200–250 g/m² (pool concrete is highly absorbent). Particularly careful on floor-to-wall transitions, at inlet jets and skimmer connections — these detail points demand gapless coverage.

Pool coating must be perfect — gaps or pinholes become leaks under water pressure.

Pro tip: At floor-to-wall transitions embed polyester fleece (60 g/m²) into the wet coat — prevents cracks from settling movement of the pool shell over the years.

Undiluted, cross to the first coat. Consumption 150–200 g/m². Let dry until fully sealed — for pool application at least 8 h, ideally overnight. Wait longer in cooler weather or high humidity.

The coat must no longer be tacky to finger pressure and leave no impressions.

Pro tip: Cover the pool during work — prevents pollen, dust and insects landing in the wet coat, which would remain permanently visible under water.

Third coat at the deep line (lower 60 cm), transitions to jets, skimmer and steps. Reinforces the most heavily loaded zone, prevents delamination at key points. Consumption 100–150 g/m². Allow full cure — minimum 14 days before water filling, 28 days for full load capacity.

Before filling, sweep the pool thoroughly — dust and insects would remain permanently visible under water.

Pro tip: Fill the pool slowly the first time (over several hours) — hydrostatic pressure builds gradually and the coating can adjust, instead of being loaded all at once.
