GEL ANTI HUMIDITE is a viscous gel product packaged in 280 g cartridge fitted with a 40 cm long tube to allow injection into the walls. GEL ANTI HUMIDITE penetrates deep into walls and impregnates them through capillary action, then slowly dries to form a tight barrier against rising damp inside the wall. The product contains high levels of silanes/siloxanes (80%). But it contains no solvents or VOCs, and is therefore safe for the applicator or occupier of the building. GEL ANTI HUMIDITE can be applied without any nuisance in inhabited premises.
