DESCRIPTION
Quickrep R309 is a single component polymer modified repair mortar for use as a fairing coat or cosmetic mortar. When mixed with water, as directed, a fine trowellable mortar results which can readily be applied to fill in pores, blowholes and blemishes on a concrete surface. Quickrep R309 is specially formulated to produce a shrinkage compensating mortar with no cracking when applied in a thin section. Adhesion to concrete and flexibility are excellent.
Quickrep R309 is supplied in 20 kg bags.
Colour: Off white or cement grey
Plastic density: 1640kg/m³
Quickrep R309 should be applied to the complete area with the minimum of trowelling. Leave for a short period before final trowelling. Finishing may be aided by flicking a small amount of water onto the surface, using a paint brush before final trowelling.
When used as a scrape coat Quickrep R309 can be applied with a brush or roller and then the excess scraped off with the edge of a steel float. In this way blow holes and minor blemishes in an otherwise fair faced concrete can be hidden.
Curing:
Good curing practice is essential even though Quickrep R309 is specially formulated to prevent shrinkage and cracking. Particular care is required in hot and windy conditions.
Preparation:
It is essential that the surfaces to be bonded are sound, clean and uncontaminated. All loose powdering material must be removed.
Concrete surfaces should be thoroughly soaked prior to application of Quickrep R309, to ensure a saturated, but surface dry condition.
Void filling:
Deeper voids should be filled prior to the application of a cosmetic coating by reducing the amount of water added when mixing to produce a trowellable putty like mortar.
Mixing:
Quickrep R309 is formulated to give an easily mixed material. For full bag quantities, it is preferable to mix the material in a Crete angle or similar forced action mixer. Alternatively, a slow speed, hand held electric mixer with a suitable paddle can be used. Over mixing should be avoided. When mixing full bags, pour 3-4 liters water in the mixing vessel and commence mixing. Add the powder to the water whilst mixing, add water as required to achieve the desired consistency. No more than 6-6.5 liters of water per 20 kg of Quickrep R309 should be added.
Coverage
One 20 kg bag of Quickrep R309 will typically yield 16 liters of mortar and will cover approximately 16m² at 1mm thickness.
