ALSAN FLASHING QUADRO is a single-component polyurethane resin for waterproofing junctions between horizontal surfaces, up-stands and various roof details in compliance with the highest solicitation category according to ETAG 005.
ALSAN FLASHING QUADRO is a root and rhizome resistant resin according to the FLL test method, is used for flameless waterproofing junctions between various roof details of heat sensitive substrates of roofs and buildings.
ALSAN FLASHING QUADRO is simple and quick to prepare as it doesn’t require a catalyst or activator. The thixotropic consistency makes it easy to install and can be applied without a primer to concrete, wood, bitumen, PVC and many metals.
FIELD OF APPLICATION
General roofing
Plaza decks & Terraces
Retaining walls
Planter boxes
INSTALLATION PROCEDURE SURFACE PREPARATION:
Concrete must be fully cured (28 days) with a minimum hardness of 24 MPa (3500 psi). Surface needs to be sound, clean and free of dust or debris, substrate moisture must not exceed 5% by mass or 16% by volume.
Concrete surface must be prepared to obtain concrete surface profile (ICRI CSP) of 3 or 4. To obtain such a profile, the use of special equipment such as shot blasting is recommended. When needed, concrete reparation must be done with appropriate products.
Without primer: traditional granulated and sanded bituminous waterproofing membranes, wood, metal, prepaint metal, concrete, polyurethane membrane (TRAFIK HP) and PVC pipe.
With primer (ALSAN 104): membranes with HDPE surface, untreated copper, stainless steel, TPO & EPDM (ALSAN 103).
PVC pipe must be sanded with sandpaper.
All metal surfaces must be cleaned with non-greasy solvent such as acetone or Methyl Ethyl Ketone (MEK). Metal surfaces must be smooth, clean and uncontaminated (free of oxidised bitumen).
APPLICATION:
Mix well the product before use.
The first layer of ALSAN FLASHING QUADRO is applied with a brush or a roller at approx. 2 kg/m2 (approx 2/3 of the product).
Apply ALSAN FLEECE 165 P, already cut to size, into the fresh embedding layer and immediately worked into the resin with a roller to remove any bubbles. Excess material will pass up/out through the open-pored fleece. If too little material was applied, white patches will be visible when the fleece is folded back.
It is essential for the fleece overlaps to be at least 5 cm wide. The resin must also be applied in between the overlaps.
Additional layers of fleece must be embedded on internal and external corners, and sufficient material again applied when embedding layers in those areas. This step can also be carried out wet in wet, which means there is no interval between the individual applications of these layers.
Without any interval, the ALSAN FLEECE 165 P can be covered immediately with another layer of ALSAN FLASHING QUADRO at approx. 1.0 kg/m2 (approx 1/3 of the product).
