Definitions

• Another subject of the invention is a method of waterproofing a roof, a deck, a balcony, a wet room or a faqade, comprising mixing the liquid component with the powder component of the kit according to the invention to obtain a composition and applying said composition to a substrate of said roof, deck, balcony or facade to form a membrane, and then drying said membrane to obtain a dry membrane having a dry thickness of from 0.5 to 6.0 mm.
• the total amount of aggregates in the powder component is preferably 20-80wt%, especially 30-60wt%.
• a CEM I cement comprises at least 95wt% of clinker, while a CEM II cement comprises at least 65wt% of clinker and at most 35wt% of at least one of blast-furnace slag, silica fume, pozzolana, fly ash, burnt shale and limestone.
• Vinyl aromatics are preferably styrene, methylstyrene and vinyltoluene .
• Vinyl acetal resins are for example polyvinylbutyral.
• the preferred vinyl halide is vinyl chloride.
• the preferred olefins are ethylene and propylene, and the preferred dienes are 1,3-butadiene and isoprene.
• Styrene-acrylate copolymers styrene-butadiene copolymers and mixtures thereof are especially preferred.
• the polymer other than polyurethane is preferably anionic .
• the polyurethane may in addition contain alkoxy silyl groups to provide self-reticulation.
• the polyurethane dispersion may also contain water-insoluble transition metal compound particles, such as zinc oxide particles.
• Polyurethanes are produced by reacting polyisocyanates (especially diisocyanates) with polyols.
• Aromatic polyisocyanates may also be used. They are selected for example from the group consisting of xylylene- diisocyanate, 2,4-toluene-diisocyanate, 2,6-toluene- diisocyanate, and methylene-diphenyl-diisocyanate.
• the liquid component may also contain additives, such as thickeners, defoamers, biocides and/or preservatives.
• the liquid component may be obtained by mixing an aqueous polyurethane dispersion (PUD) with an aqueous dispersion of the other polymer (s) and adding the surfactant.
• PID aqueous polyurethane dispersion
• s aqueous dispersion of the other polymer
• the weight ratio between the liquid component and the powder component i.e. the weight of liquid component divided by the weight of powder component
• the weight ratio between the liquid component and the powder component is preferably 2:1 to 1:3. It is especially adjusted depending on the polymer content in the liquid component.
• the final membrane can be the result of the application of several successive layers, for example 2 or 3 layers. Its (total) dry thickness is preferably between 1.0 and 5.0 mm, especially between 2.0 and 4.0 mm.
