Composition

• Liquid component: polymer dispersion, additives
• Powder: special cements, mineral aggregates, additives, pigments

Substrate

Suitable substrates

• Masonry in accordance with DIN EN 1996, e.g. made of bricks, hollow blocks and solid blocks made of lightweight concrete and concrete, slag bricks, sand-lime bricks, aerated concrete blocks, concrete shuttering blocks, mixed masonry
• Concrete / reinforced concrete in accordance with EN 206-1 in conjunction with DIN 1045-2
• Plasters of category CS III or CS IV according to DIN EN 998-1
• Existing bitumen-based paints and coatings
• Cement screeds
• Old, firmly adhering tile coverings

Properties/tests

• The substrate must be frost-free, surface-dry, load-bearing, clean and free from contamination and separating layers of any kind (e.g. paint coats, formwork oils).
• The surface of the substrate must be dry.
• Plasters must be hardened.
• Concrete must be at least 3 months old in accordance with DIN 18535 – Sealing of tanks and basins in solid construction.
• Substrates containing tar are not suitable and must be completely removed.

Substrate

Vorbereitung

• Sintered layers or stubborn dirt must be removed mechanically (diamond grinding).
• On the surfaces to be sealed, external corners must be chamfered and internal corners must be provided with a sealing fillet or sealing tape (in accordance with the regulations).
• For masonry according to DIN 1053, butt joints wider than 5 mm must be sealed with mortar on the outside, e.g. for bricks that are not laid “crisply".
• Depressions larger than 5 mm, such as mortar pockets or break-outs, must be filled in advance with INTRASIT ^® SM 54Z / INTRASIT^® RZ1 55HSP.
• Special measures are required to close the pores in masonry made of lightweight or concrete blocks with porous structure (e.g. scratch coat with PROLASTIC^® 55Z). The filler must be dried/set for approx. 2 hours before the next work step.
• Concrete needs to be checked as well. Existing defects and formwork ridges must be removed in the same way as for masonry.
• Pores, open or concealed, can lead to blistering in the fresh coating, e.g. when exposed to sunlight. To minimize the risk of blistering, a scratch coat of PROLASTIC^® 55Z should be applied. The filler must be allowed to dry/set for approx. 2 hours before the next work step.
• Before applying PROLASTIC^® 55Z, the surface to be sealed must be thoroughly cleaned (e.g. by vacuuming) and primed with IMBERAL Aquarol 10D.
• Clean existing bitumen-based paints and coatings (e.g. with a high-pressure cleaner) and apply a scratch coat of PROLASTIC^® 55Z after drying.
• EPS and XPS panels must first be treated with a suitable reinforcement mortar and mesh in the plinth area.
• In transition areas between the structure and installation elements such as windows or doors, these must be roughly sanded and then HADALAN HV Uni 30DD is applied.
