Description
SPU-301H is a one component moisture-curing polyurethane waterproof coating
especially used for horizontal plane. When this coating is applied on surface substrate,
it has chemical reaction with the moisture in the air, and then it will form a seamless
elastomeric rubber waterproof membrane.
Where to use
●Undergrounds;
●Parking garages;
●Subways in open cut method;
●Channels;
●Kitchen or bathroom;
●Floors, balcony and unexposed roofs;
●Swimming pools, man-made fountain and other pools;
●Top plate at plazas.
Advantages
●Good tensile strength and elongation;
●Both high and low temperature resistance;
●Strong adhesive;
●Seamless, no pinholes and bubbles;
●Resistance to long-term water erosion;
●Corrosion-resisting and mould-resisting;
●Convenient to apply.

Packaging
SPU-301H is sealed in 20kg or 22.5kg pails and transported in wooden cases. Each wooden case can be contained 36 pails of SPU-301H.
Storage
SPU-301Hmaterialshouldbestored by sealed pails at dry and well-ventilated placesand protected from sun or rain. The temperature in stored places can not be higher than 40° C. It can not be closed to fire sources. The normal shelf life is 6 months.
Transportation
SPU-301H is needed to be avoided sunshine and rain. Fire sources are forbidden during transportation.
Application System
lConstructive System
The system is basically consisted of substrate, additional layer, waterproof coated membrane and protection layer.
lCoverage
1.7kgper m2 gives dft 1mm minimum. Coverage may vary with the substrate condition during application.
lApplication Method
Surface preparation
Surfaces should be dry, stable, clean, smooth, without pockmarks or honeycombs and free from any dusts, oil or loose particles. Cracks and surface irregularities need to be filled by sealants and do additional waterproofing. For smooth and stable surfaces, this step can be skipped.
