Products

• Single-component liquid, which improves cohesion and workability and is easily gauged as required
• Provides waterproof repairs, renders and toppings that are resistant to freezing and thawing
• Good tensile, flexural and UV-resistant properties, which facilitate even thin applications
• Super bonding to concrete, masonry, stonework, plaster, block board, clip bricks, ceramic tiles, etc.
• Free from chloride admixtures, it improves the quality of site-batched cementitious mortars and slurries
• POWERGRACE SBR latex power can be diluted with water (1:4-6), depending on the type of application
• Improves the elasticity, flexibility and tensile strength of cement

The object of the surface preparation is to achieve a clean, sound surface with a good mechanical key. All substrates should be cleaned and free of dust, plaster, oil, paint, grease, corrosion deposits and any other deleterious substances. Latence should be removed by mechanical means. Smooth substrates must be mechanically roughened, e.g., by scrabbling, a needle gun, or grit blasting, to provide an adequate key. Corroded reinforcing steel should be exposed around its full circumference and cleaned to remove all loose scale and corrosion deposits. It is always advisable to clean the steel to a bright condition. The use of emery cloth, grit, or sandblasting is recommended.

Reinforcing steel must be primed with a zinc-rich primer immediately after cleaning. The concrete substrate should be thoroughly dampened with water and any excess removed before being primed by thoroughly scrubbing in a slurry coat of 1 volume of SBR (latex) 1 volume of water to 3 volumes of fresh cement. To obtain a smooth consistency, the cement should be blended slowly into the liquids. Stir frequently during use to offset settlement. Avoid 'puddling' the slurry coat. The topping must be applied to the wet slurry. If the slurry dries out, it must be removed and the clean substrate re-primed.

Tools and equipment should be washed with water immediately after use.

• All surfaces, including edges, must be primed
• All applications should be wet; the primer must not be allowed to dry
• The level of added water in the mix designs may need adjusting to achieve the required consistency
• In general, water content should be kept to the minimum necessary
• For consistent performance, the use of clean, dry sand is recommended
• Where wet sand is used, reduce the added water level as appropriate
• Protect uncured mortar from frost
• Do not retemper mortar or primer after the initial set
• The minimum application temperature is 10 °C

Slurry primer: Approximately 4–5 m3/litre, depending on substrate porosity.

POWERGRACE SBR (latex) has a shelf life of 12 months if kept in a dry, unopened condition.
