Description
Polyguard 101 is an acrylic aliphatic based protective and anti carbonation coating for reinforced concrete and masonry surfaces. It consists of a single component pigmented coating ready for immediate site uses. Polyguard 101 is applied on a silane siloxane penetrative primer which works by penetrating into the pores of concrete, masonry or stone work and reacts with moisture or water vapor that is present thus forming a hydrophobic silane siloxane seal to the capillary pores. This hydrophobic treatment is very effective in reducing the passage of water and water borne salts whilst allowing moisture vapor to dissipate to the atmosphere.
TDS For Polyguard 101
- Step by Step
Surface Preparation
The surface must be structurally sound and free of oil, grease, dust and other contaminants which will affect the bonding. Any structural cracks and potholes shall be repaired with a suitable repair mortar from the Polycrete* range of repair mortars. The surface to be treated should be presaturated with water prior to application. However, any standing water shall be removed prior to application.
Priming
Apply a penetrative primer coat of Polyxane* to the prepared dry surface. this will impregnate the surface and form an impervious barrier to moisture and other environmental contaminants. For best results apply the primer @ 4-5 m²/l/coat. Depending on the porosity and nature of the substrate a second coat is recommended to be given after the first coat has dried off completely.
Mixing
Mix the contents of the Polyguard 101 pail thoroughly before use.
Application
The first coat of Polyguard 101 is to be applied on the dry primer at the rate of 2.5 m2/ltr for 200 microns d.f.t. the coating can be applied with a brush, roller or an airless spray. Apply the second coat at right angles to the first coat at the same rate. The second coat is to be applied only after the first is completely dry.
Curing
The applied material will achieve its full properties after 7 days of application.
