specialized waterproof material  Product features1.Thanks to specialized waterproof material, our  membrane for -20 to 70   Celsius degree is more flexible, thus fitter with surfaces of irregular solids and narrow and small area. Besides, its installation is easier and more convenient.2.The washing room waterproof material is safe and environment-friendly.Apply cement-based materials by wet-application, without primer, hot melting, volatile solvent, fire hazard, or any harm to human beings.
3.It is adaptable to wet substrate surface and rough one as well.
4.Its thickness is uniform, addressing the problem of uneven thickness occurring during coating application and avoiding the hidden dangers due to inaccurate proportioning as well.5.Its damage-resistance is high.  And it is easy to mend the damage if any. 6.Foolproof-styled installation makes its application quite easy.7.Both Internal and external surfaces have good bond performance to cement-based materials, thus it could be easily adhered by tiles afterwards without any surface treatment.   Technical IndexNo.ItemTechnical Index1soluble content/(g/m2)       ≥13002tensile propertytension/(N/50mm)≥350Elongation upon Maximum Tension/%≥303heat resistance70°C No Slip,No Flowability,No Drippage4  low temperature flexibility/°C-20No crack5 impermeability0.3MPa,120min impermeable6Peeling Strength/(N/mm)≥Membrane & Membrane1.0Membrane & aluminium materials1.57Peeling Strength against cement mortar/(N/mm)    ≥2.08Peeling Strength against cement mortar after  immersion/(N/mm)  ≥1.59Watertightness against Rivet Stemapproved Scope of ApplicationApplicable to waterproof and moisture-proof works on walls or floors of kitchens and lavatories. Storage and Transportation1. It is supposed to be stored in a place dry, ventilated, far away from fire.
2.During storage, the membrane should be placed vertically, not leaning or overlapping. And keep it away from sunshine and rain.
3.Under normal condition, storage period is one year from manufacture date on. CertificationISO9001:2000, ISO9001:2008, ISO14001:2004

Construction points1.Substrate Preparation: clear away dust and sundries on the substrate surface by brooms and shovels. convex location should be treated as arc-shape with semidiameter 50mm. Dry substrate surface is supposed to be sprayed wet ,but without ponding water.
2.Reinforcement of joints: Joints should be painted coatings as enhanced Layer.
3.Application of Cement Mortar: make cement slurry as per water cement ratio 0.3~0.4. The thickness of the mortar layer depends on smoothness of substrate surface( Generally, 1~3mm). During the application, make sure it is compacted and leveled.4.Membrane-installation for extensive area: remove the isolating film beneath of the membrane then lay the membrane on the substrate with mortar. Lap the membrane by means of self-adhesive with lap width according with design or regulation and stipulation. 5.Mud -extracting and Air-eliminating: slap the membrane surface with wood floats or rubber plates to eliminate the air beneath the membrane, making the adhesion between membrane and cement slurry more compact.
6.Overlapping long & short-side of the membrane: get the overlaps self-adhered. Using portable lump breakers (roll), compact the membrane by rolling depression to eliminate the air beneath, making the adhesion firmer.7.After3-4-day maintenance (period depending on curing temperature), get rid of the isolating film on the membrane and install the tiles on the membrane directly.
