Ardex K301 – Fast Setting Resurfacing and Levelling Compound
Ardex K301 – fast setting resurfacing and levelling compound for concrete. It is a grey powder consisting of special cements, graded aggregates and high quality synthetic resins. When mixed with water, a fluid mortar is produced which sets after approximately 1 hour and can normally be walked on after 2-3 hours at 20°C. It can be applied from 2mm to 20mm in a single application. Once set and hardened, it is usually ready to receive light rubber wheeled traffic after 48 hours at 20°C.
Ardex K301 will smooth and level concrete surfaces such as balconies, patios, domestic driveways, garages, walkways and other concrete surfaces exposed to normal foot and rubber wheeled traffic. The product can also be used for filling holes and resurfacing damaged floors, such as concrete or cement/ sand screeds, as well as pre-smoothing concrete floors prior to the application of a suitable damp proof membrane, such as Ardex DPM 1C/1CR.
Pour the mixed product onto the prepared and primed substrate. The mixed mortar will flow out and self-smooth during the first 10 minutes of its 30 minute working time. Spread the mortar using a steel trowel or float. For larger areas its recommended to use a gauging tool with thickness height adjustment
to spread the mortar. The applied surface can be left with a trowelled finish. Alternatively, to create a more non-slip finish, the water content should be reduced and then ‘broom finished’ once the initial set has occurred (approximately 40 minutes under normal conditions).
Once set, the freshly applied K301 must be protected from adverse climatic conditions e.g. rapid drying air flow, direct strong sunlight, frost, etc., or appropriate curing measures taken until hardened. Apply at temperatures above 5°C.
If a second layer is required, this should be applied after the first layer has fully hardened. The first layer should be machine sanded (paper 16 to 36), cleaned and primed with Ardex P51 Primer diluted 1:1 with water for dry indoor use, and diluted 1:7 with water for external use or damp interior areas. The dilution rate of 1:7 should not be exceeded for external applications
All information on surface preparation, mixing and thickness applications can be found on the technical datasheet.
