Microshield 5ltr

Microshield is a ready to use, water based water repellent based on silanes and siloxanes. Microshield is safe and easy to apply by brush, roller or coarse spray and air cures rapidly even at near zero temperatures. When dried it provides a colourless, protective micro-porous layer that is highly water shedding and water repelling against driven rainwater. Unlike traditional solvent based silicone fluids Microshield can be applied onto fresh, cured, highly alkaline, cement based surfaces, whether dry or damp. It is not suitable for application to wet, green uncured cements/concrete, or as a DPC layer.

Surfaces suitable for treatment include:

• External walls of brick, concrete, cement render finished. Walls need to be sound and free from cracks and pointing defects.
• Concrete floors – cement screed or concrete floors can be treated to consolidate and bind friable, porous surfaces and produce a dust free, breathable micro-porous seal.
• Any new or repaired cementitious surface. These can be treated and water proofed immediately the structure is cured and hard.

Features and Benefits

• Water based, non hazardous, one coat system is quick and convenient to apply
• Brushes, rollers and spray equipment rinse out with water (Note: Clean brushes etc immediately after use, do not allow to dry out, cured product is not water soluble)
• Solvent free, non flammable. No fire risks, hazardous solvent vapours or fumes.
• Not effected by the highly alkaline content of fresh new cement and so can be used immediately concrete is cured (3-5 days)
• Forms a clear, dry, invisible layer which prevents the penetration of wind driven rain or surface moisture.
• Micro-porous nature of the treatment allows rapid dry out and surfaces to breath.
