WETISOL Ecto 2K Elastic — elastic polymer-cement waterproofing

Cementitious coating waterproofing

The elastic WETISOL Ecto 2K Elastic coating made of cement powder and acrylic dispersion is intended for structures where microcracks and small deformations are possible. It is used to waterproof pools, tanks, vessels, foundations, plinths, balcony slabs and hydraulic structures, protecting concrete from groundwater, sea water, carbonation and de-icing salts. Elongation at break is at least 55%, the watertightness of the mortar is not below W12, and cracks up to 1.5 mm wide are bridged. No primer is needed, the coating is UV-resistant and remains elastic at sub-zero temperatures.

ManufacturerWetisol (INGRI) — OOO “Ingri”
Typecoating waterproofing
Usefoundations and basements, tanks and pools, hydraulic structures and dams, indoor rooms
Basetwo-component elastic polymer-cement coating: comp. A — powder (special cements, modifying additives), comp. B — acrylic dispersion
Colourgrey (finished coating); comp. B — white liquid
Packaging30 kg kit: comp. A — 20 kg bag, comp. B — 10 kg canister
Application methodprotection of structures (SP 28.13330.2017, cl. 5.3.1) against groundwater, liquid aggressive media and gases, sea water, carbonation, de-icing salts; waterproofing of hydraulic structures with minor deformations, pools, tanks, vessels, foundations, plinths, balcony slabs, internal and external parts of buildings, structures with possible microcracks, above-ground parts; clean the substrate mechanically (milling cutters, rotary hammers, sandblasting, water jetting, diamond grinding), wash with a high-pressure water jet, remove excess water — the substrate should be matt-damp, not wet; do not apply to a dry surface, in the presence of leaks and seepage, or below +5 °C; no primer required; components at 20±2 °C, shake comp. B for 30–60 s, add A to B while mixing with a mixer at up to 500 rpm for 2 min, pause 2–3 min, mix again for 1–2 min (do not use gravity mixers); A:B = 2:1 by weight, do not add water; by brush, broom or the pneumatic sprayer of a mortar station in layers of 0.5–1.5 mm, subsequent layers perpendicular after 2–4 h (below +10 °C — up to 2 times longer); if the material rolls up, moisten the surface; joints and cracks 0.5–1.5 mm, floor-wall junctions, construction joints — reinforcement with alkali-resistant fibreglass mesh tape at least 200 mm wide in the first 1–1.5 mm layer; tools — with water
Application temperatureair and substrate +5…+30 °C; material 20±2 °C
Curingpot life at least 60 min at +20 °C (GOST R 56378); for 24 h protect from precipitation, mechanical impact and sub-zero temperatures; service and application of subsequent coatings after 7 days; final properties after 28 days
Key propertiesrelative elongation at break at least 55% (GOST 11262); bond strength to the substrate at least 1 MPa (GOST R 58277); watertightness grade of the mortar at least W12 (GOST 31383); bridges cracks up to 1.5 mm wide; density of the ready compound 1,400–1,750 kg/m³ (GOST 31992.1); maximum aggregate size 0.16 mm, not more than 1% (GOST 8735); elasticity at sub-zero temperatures; high frost resistance of the contact zone; UV resistance; vapour permeability; service temperature from −50 °C to +80 °C
Layer thickness2–4 mm (0.5–1.5 mm per pass)
Consumption1.5–1.7 kg/m² per 1 mm; 2 mm system in 2 coats — 1.6 + 1.6 kg/m²; joints and cracks 3 mm with fibreglass mesh reinforcement — 2.0 + 2.0 kg/m²
Shelf life12 months from the date of manufacture in covered dry warehouses (air humidity max 60%) at +5…+30 °C, in intact original packaging
StandardsTU 20.16.53-090-94613022-2021; SP 28.13330.2017; SP 71.13330.2011
