Masonry Waterproofing Cream
Microshield Ultra is a water-based masonry waterproofing cream, designed to provide long-lasting and reliable water repellence. It imparts a strong beading effect to mineral substances such as brickwork and façades.
Microshield Ultra provides comprehensive protection for brickwork and façades against efflorescence and destruction by water soluble pollutants. It also protects against frost damage and the attack of micro organisms.
Surfaces treated with Microshield Ultra also benefit from improved thermal performance. Heat loss through “wet” walls is reduced, improving the indoor environment and saving valuable energy and money.
Benefits of Microshield Ultra
Microshield Ultra is a creamy impregnating agent, based on silanes and siloxanes. Our waterproofing cream protects the material while preserving the water vapour permeability. It doesn't affect the appearance of the material surface.
Water simply beads and runs off, and the material can maintain its natural moisture balance. The remarkable penetration of Microshield Ultra into the substrate guarantees exceptionally long-lasting and reliable protection from penetrating damp.
Microshield Ultra is suitable for use on most kinds of mineral substances for example:
Bricks and clinker
Natural stone
Mortars
Render
Porous concrete
Concrete
Limestone
Beading Effect
Substrates treated with Microshield Ultra will exhibit a strong beading effect. This develops within 7 to 10 days of treatment. The beading effect lasts between 2-3 years depending on the substrate condition and exposure to weather conditions.
Preparation
Substrates to be treated must be in sound condition. Structural defects such as cracks, cracked joints, defective connections, rising damp and hygroscopic moisture must be remedied first.
Substrates to be treated should be dry and free from oil, grease, dust, dirt and biological growth (moss or algae). Any contaminated substrates should be cleaned in conjunction with BS8221-1:2000, “Code of practice for cleaning and surface repair of buildings. Cleaning of natural stones, brick, terracotta and concrete”. It is important when cleaning the substrate not to use detergents as these can interfere with the hydrophobic effect of Microshield Ultra.
Test a small, representative area to ensure the product is not repelled and also that the dry finished surface appearance is acceptable.
Applying Microshield Ultra
Microshield Ultra Cream can be applied by roller, brush or airless spraying at a rate of 0.2l/m². A single application of Microshield Ultra at this rate is generally sufficient. Due to its creamy consistency, you can simply apply the waterproofing cream onto walls and overhangs without dripping or running. The milky-white cream disappears without any residues left on the surface.
After approximately 2 hours (@ 20 degrees celsius) the application is rain tight (this will be extended for colder conditions), the water beading effect develops within 7 days of treatment. Microshield Ultra is able to withstand even extreme weather conditions without any affect to its performance.
Microshield Ultra should not be applied in cold conditions when rain is expected within 24 - 48 hours.
NB: The substrate must be clean, dust free and dry. Temperature of the material, air and substrate: from min. +10 °C to max. +25 °C for a minimum of 24 hours.
Application Method
Clean and prepare substrate as above.
Apply Microshield Ultra by brush to areas close to non-target surfaces (windows etc.)
On larger areas, roller Microshield Ultra onto the substrate at a rate of 0.2l/m²
Visibly check substrate for complete coverage, brush Microshield Ultra into any deep joints or voids that may have been missed.
Leave Microshield Ultra to penetrate the substrate and develop beading effect.
