Ac Guard

DESCRIPTION
AC Guard 59 is a one component waterproofing, UV stable and high flexsible. This is an acrylic waterbased coating that dries to a flexible highly water resistant coating providing durable protection against rain, wind and sun.

ADVANTAGES
• Superior water resistance – resistant to wind driven rain 
• Acrylic based – durable, touch, UV resistance 
• Easy to use 
• Effective waterproofing compound 
• Can bridge minor surface imperfections
• Low lustre flexible finish – can be overcoated or left as a final coat 
• Can be tinted with universal paint tints 
• Non toxic - formulated without lead or mercury 
• Membrane system – can waterproof larger cracks and gaps without needing to fill - It can accommodate slight movement of the substrate.

COMPLIED STANDARD
• ASTM D412 -16
• ASTM D7234-2

RECOMMENDED USE
• Water tanks, Water treatment Tank, Fire tank 
• Concrete flat roofs 
• Finishing o Sealing joints, laps and roofing screws on various kind of roofs (roof tile, zinc).
•  Parapet walls. 
• Good exterior paint that will not crack
• Excellent wood paint due to its flexibility

ADHESIVE 
AC Guard 59 adheres to plaster, concrete, tiles, metal, asbestos, bricks, wood, polycarbonate sheeting and most painted and coated surfaces.

METHOD TO USE
Surface preparation
Surface must be clean, dry and sound,  masonry, peeling paint, release oils, mould and fungus, and bleeding stains. Cracks larger than 1mm in width should be repaired with mortar repair, sealant to bridge the crack.

New plaster and concrete 
Fresh plaster and concrete has to be allowed to cure for 30 days prior to coating and should have a pH of 11 or less. Unweathered areas must be power washed or scrubbed with a detergent solution and rinsed with water to remove surface salts that could bleed through and interfere with adhesion. 

New galvanized iron and mild steel surfaces 
Scrub down surface with a galvanized iron cleaner. Rinse with water. Rusted galvanized iron and mild steel surfaces Rusted areas need to be wire brushed to remove rust deposits. 

Previously coated surfaces 
Matt water-based coatings can be directly over coated. Glossy and sheen paint surfaces should be sanded If there is any uncertainty that the previous painted surface may not be well adhered to the substrate, we recommend that the old paint is completely removed before recoating.

Instructions for use 
• Ensure that surfaces are prepared as above 
• For colour consistency, ensure that batch numbers on containers correspond 
• Stir before use As a coating 
• Apply AC Guard 59  with brush or roller
• Allow to dry for 6 hours, depending on temperature and humidity 
• Recoat and ensure complete coverage with AC Guard 59  
• After final coat, ensure that any remaining pinholes are overcoated as a waterproofing system 
• For structural cracks, holes and joints, a fabric membrane must be used 
• Drying times are dependant on environmental conditions. High humidity and low temperatures will extend drying time.
