MasterProtect® 300 is a single component high performance elastomeric, waterproof coating based on water borne acrylic copolymers. When cured, it provides an aesthetic, durable, breathable coating which is waterproof, crack bridging and protects the structure from water-borne aggressive agents which initiate corrosion.
Provides barrier against salts and atmospheric gases.
Waterproof – protects concrete from waterborne salts.
U.V. stable – maintains its appearance.
Breathable allows water vapour to escape from the substrate avoiding blisters.
Application
The product is designed for the protection of reinforced concrete structures. It is also suitable as a seamless and elastomeric waterproofing coating for timber, fibre cement and corrugated sheets, metal roofing’s and asphalt.
Areas of application are: Concrete repairs, Marine environments, Bridge and highway structures, Underpasses, Multi storey car parks, Commercial buildings, Industrial buildings, Waterproofing a variety of substrates & Flat roofs and sloping roofs.
Dosage
Approximately 0.64 L/m2 to achieve a DFT of 400 microns (applied in a minimum of two coats). Wet film thickness per coat ± 320 microns. Minimum coverage: 0.40 L/m2 to achieve a single DFT of 250 microns.
