FLEXIGUM h2o is a monocomponent waterproofing product based on elastomeric resins and rubber micro granules resistant to U.V rays.
Once the action has taken place, a highly elastic and waterproof membrane is formed, non-slip, weather-resistant and effective even in marine areas.
WHAT IT’S FOR
Waterproofing of all roofing surfaces: terraces, balconies, roofs, galvanized sheets, nozzles, gutters, eaves and worn supports already waterproofed with bituminous based products.
METHOD OF USE
- SURFACE PREPARATION
The surface to be waterproofed must have a sufficient water flow gradient and only a small water stagnation can be tolerated.
The support must be compact and flat, in the absence of such conditions, adequate preparation of the same should be provided.

2 – Surfaces with cement screeds, vertical plastered, old and / or new: Before waterproofing, if deteriorated screeds are present it will be necessary to remove and rebuild them with additives mortar and they must be dried and aged (for new screeds 28 days will be necessary for the complete aging, the residual humidity must be less than 4% by weight to be determined by professional hygrometer).
Some covers must include the insertion of breather elements for the escape of water vapor.
3-surfaces already waterproofed with sheaths or bituminous products: They must be perfectly clean and free of dust; repair any lacerations, tears or detachments using bituminous products; check the condition of any expansion joints and, if they have deteriorated, proceed with their reopening, cleaning and reconstruction.
Apply the appropriate primer (POWER GRIP – Universal primer for smooth or non-absorbent surfaces; – NTX PRIMER h2o – Specific primer for new or old acrylic and bituminous membranes) on the substrate to be waterproofed.
