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.

An active leak in concrete, brick masonry or natural stone is stopped with the WETISOL Ecto SF hydraulic plug even under a constant water inflow. The one-component chloride-free cement mix starts to harden after 1–2 min, reaches a compressive strength of at least 15 MPa after 1 h and 45 MPa by 28 days. It is also used to seal leaking joints and cracks, fill formwork tie holes and quickly fix bolts, anchors, injection packers and pipes. The compound is not intended for expansion joints and moving cracks; packaging — 1 and 15 kg buckets.

| Use | leak repair, joints and abutments |
| Base | one-component rapid-hardening dry mix on a cement binder; contains no chlorides |
| Packaging | polyethylene buckets, net 1 kg and 15 kg |
| Application method | rapid elimination of active leaks in concrete, brick masonry and natural stone, incl. under a constant water inflow; sealing of leaking joints and cracks; filling of holes from climbing formwork; interior and exterior works; widen the leak point with a rotary hammer or by hand at an angle of 45° to a depth of at least 3 cm, remove weakened concrete; water ~0.2 l per 1 kg, quickly mix with a spatula to a viscous dense mass, shape it in rubber gloves, after the start of setting press it firmly against the leak for about 2 min, release the pressure smoothly, without twisting movements, remove the excess; prepare strictly for one hole at a time, large defects — in several stages; do not apply to frozen substrates; not for expansion joints and moving cracks; do not re-mix |
