Concrete substrates must be sound and of sufficient compressive strength (minimum 25 N/mm2) with a minimum pull off strength of 1.5 N/mm2. The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc. If in doubt apply a test area first. Concrete substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and achieve an open textured surface.
Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed. Repairs to the substrate, filling of blowholes/voids and surface leveling must be carried out using appropriate products from the Sikafloor®, SikaDur® and SikaGard® range of materials. The concrete or screed substrate has to be primed or leveled in order to achieve an even surface. High spots must be removed by e.g. grinding.
All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum.
When parts A and B have been mixed, add the quartz sand F34 0.1 – 0.3 mm and mix for a further 2 minutes until a uniform mix has been achieved. To ensure thorough mixing pour the materials into another pail and mix again to achieve a consistent mix. After mixing leave the mixture for 3 minutes to react before applying. This so called induction time minimizes the appearing of colour shade differences. When the Sikafloor-326 is finished using a pigmented topcoat, this procedure is not necessary. Over mixing must be avoided to minimize air entrainment. The product has been designed to be filled and mixed in one pail, without the need to split the mixture over two pails. When splitting the product over 2 pails, make sure to split the A-component and the B-component before mixing, and do not split the mixture. When splitting the mixture, differences in reaction-time can lead to colour differences on the floor.

The manufacturers data sheets are available for download from this website. It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
