POSSIBLE SUBSTRATESThe type of shapes are those usually acceptable

for upstands waterproofing (see DTU series 43), such as masonry, metal upstands, timber as well as insulation materials such as fibre-reinforced perlite, cellular glass…Other substrates: please, consult SOPREMA.

The substrate must be in good condition, clean, dry, free of any greasy substances.

PRESEnTATIOnAlsan® flashing® is a single-component bituminous

polyurethane resin which is applied in situ without a primer, using a roller or wide paintbrush.

InTEnDED USEThe Alsan® flashing® process can be used on all upstands

in new or renovation works. It is used in conjunction with SOPREMA waterproofing consisting of an SBS elastomer bitumen or a sandded or slate-coated APP main surface. Designed for terraces accessible to pedestrians or vehicles as well as non-trafficable and technical roofs.Its variant Alsan® flashing® garden is suitable for waterproofing items in direct contact with soil (green roofs, garden roofs, flower boxes, …) .

Alsan® flashing®bility

no more cap protections on roofs.The outstanding reliability of the Alsan® flashing® process means it can be used without any rainwater runoff device.This exclusive advantage means there is no need for:- masonry features such as drip caps or tuck-ins,- metal flashing strips,- but it also leads to genuine savings of up to 50 % compared to traditional upstands with a flashing strip, more in the case of masonry upstands (about 75 % when the drip cap is not glued).

advantagesFIRE SAFE TOOMost fires start on upstands: upstands

under roof overhangs, at the bottom of shingles, underneath inflammable cupolas, on timber supports or panels made of wood derivatives, upstands on combustible insulation, upstands underneath an air intake, underneath glazing…Alsan® flashing® is a flame-free process that enables upstands to be treated safely anywhere where they constitute fire traps.

OUTSTAnDInG RELIABILITY- Perfect, permanent bonding to the substrate. Adherence

tests carried out in situ by SOPREMA’s Liquid Waterproofing department and laboratory on new and old flashing® sites were done in compliance with standard NF P 98-282. The results showed adherence performances considerably higher than with traditional processes: from 3 to 4 MPa compared to 0.5 MPa for welded membranes.- Liquid, it adapts to any type of shape.- Its elongation capacity of 500 % allows it to absorb movements without cracking.- Applied in one shot, Alsan® flashing® eliminates the lap joints required with sheet products.- The physico-chemical properties of Alsan® flashing® do not alter over time. It is UV-resistant and remains flexible even at low temperatures. No more delamination as with aluminium protection systems or unattractive wrinkling.

neatly finished upstands.

Alsan® flashing® can be left visible as it is UV-resistant. However, when the roof is visible, slate chippings - same colour

as the rest of the surface can be added to a layer of freshly applied Alsan® flashing®.The fact that there are no joints also guarantees a regular, homogeneous and attractive effect. The elimination of tuck-ins, drip caps or flashing strips also allows for greater architectural freedom : curves, pure lines.The result is distinctly better roof-terrace aesthetics.An aluminium finish can be obtained by applying a coat of Cural or a coloured finish in the shades in the Curfer range.

SIMPLE, SPACE-SAVInG TOOLS

A SInGLE COMPOnEnT PRODUCTAlsan® flashing® comes ready to use and requires no mixing on

the worksite.

nO PRIMERAfter laying the bituminous waterproofing product on the main surface (a membrane that meets a Technical Approval or SOPREMA installation specifications), the upstand is treated with Alsan® flashing® without a primer.REMInDER: Alsan® flashing® must not be applied on top of existing primer.

A SIMPLE PROCESSThe Alsan® flashing® process consists of only 3 simple stages:• Preparation of the substrate (see preparatory work opposite)• Laying of the Renfort RS®, sticking it in the corners on top of an Alsan® flashing® coat (500 g/m2)• Two coats of Alsan® flashing® (Alsan® flashing® garden) (900 g/m2 + 700 g/m2).

RAPID POLYMERISATIOnAfter polymerisation under the effect of the ambient humidity, Alsan® flashing® forms a truly waterproof coating. Polymerisation generally takes between 2 and 5 hours per coat depending on the weather conditions.

PRACTICAL RAIn PROTECTIOnThe structure is protected against the rain as soon as the Renfort RS® is laid and impregnated.

preparatory workAlthough no primer is needed, the substrate

must still be clean and dry, and haveundergone some preparatory work:

- remove dust from wooden substrates,- remove grease from metal upstands,- trim any aluminium or stainless steel

reinforcements,- sweep away any loose slate chippings using

a metal brush for membranes with mineral protection,

- sweep away any loose sand for sanded membranes,

- remove any thermofusible film.

RECOMMEnDATIOnAlsan® flashing should be used

at temperatures between +5°C and +35°C. Veils and cans should be held in a cool, dry place before use.
