Wetisol Spray 400 — hot-spray polyurea
Sprayed polyurea for foundations, tanks, roofs and bridges: a seamless membrane with 350–450% elongation, working from −60 to +90 °C.

WETISOL INSEAL 150 is a cementitious dry mix with chemically active additives that crystallise in the pores and microcracks of concrete and give a self-healing effect. It is applied to new and old concrete and reinforced concrete structures from inside or outside, regardless of the side of water pressure: foundations, basements, underground car parks, tanks, wastewater treatment plants, dams, bridges, tunnels. The watertightness grade of treated concrete rises by at least 3 steps, while the concrete retains its vapour permeability. The mix is resistant to aggressive media, petroleum products and sea water.
| Manufacturer | Wetisol (INGRI) — OOO “Ingri” |
|---|---|
| Type | penetrating waterproofing |
| Use | foundations and basements, tanks and pools, hydraulic structures and dams, tunnels and metro, bridge structures |
| Base | dry penetrating waterproofing mix on a cement binder: Portland cement, sand, chemically active additives (crystallisation in the pores and microcracks of concrete, self-healing effect) |
| Colour | light grey (finished coating); the dry mix is grey with white inclusions |
| Packaging | 5 kg and 15 kg plastic bucket |
| Application method | clean the surface of dirt, paint coatings, lime, efflorescence, laitance and petroleum products; open up defects and static cracks and repair them with LEVL RemTixo compounds; soak the substrate generously; water : mix = 0.20–0.25 : 1 (1.00–1.25 kg of water per 5 kg, 3.00–3.75 kg per 15 kg), mix with a drill at up to 400 rpm with an auger paddle to a creamy consistency without lumps; apply with a scrubbing brush, stiff brush or plaster sprayer, rubbing in: horizontal surfaces — 1 coat, vertical surfaces — 2 coats, the second after 2–4 h perpendicular to the first; cut-off of capillary rise between a concrete foundation and a wall of porous materials: a water:mix = 1:1 slurry is poured through a funnel into holes flushed with water, caulking with LEVL RemTixo Rapid; effective only on cement-containing substrates (weakly — on concretes with microsilica and polymer concretes, not applicable to gypsum and lime mortars) |
| Application temperature | air and substrate +5…+35 °C (at +5…+10 °C — minimum water, at +25 °C and above — maximum); no direct sun, strong wind or rain |
| Curing | pot life 20–30 min (+10…+30 °C); second coat after 2–4 h; for 3 days protect from mechanical impact and frost and keep moist (water spraying, film), on the water-pressure side — up to 14 days; the main densifying effect occurs in the first 2 weeks; protective, paint and finishing coatings and screed — no earlier than after 7 days |
| Key properties | increase in the watertightness grade of treated concrete by at least 3 steps over the initial grade (GOST 12730.5-2018); bulk density 1,350±100 kg/m³ (GOST 8735); mortar mix density 2,050±50 kg/m³; moisture content max 1.0 wt. % (GOST 8735); service in the pH range 5–14; retains vapour permeability; resistance to aggressive media, petroleum products, sea water; service temperature from −60 °C to +400 °C |
| Consumption | 0.8–1.3 kg/m² (horizontal — 1 coat, vertical — 2 coats); cut-off — 0.8 kg/dm³ of ready slurry in the holes + caulking with LEVL RemTixo Rapid 0.1 kg/hole |
| Shelf life | 12 months from the date of manufacture in unopened undamaged packaging at −15…+50 °C, protect from direct sun and moisture |
| Standards | TU 23.64.10-071-94613022-2019; GOST 12730.5-2018 |
