Sika Sikafloor 375 is a two part, solvent free, low viscosity, tough elastic, crack-bridging polyurethane resin, for car parks, industrial floors, storage facilities and workshops.

Best Uses

Sika Sikafloor 375 may only be used by experienced professionals. For crack bridging, trafficable, slip resistant wearing layers. Sika Sikafloor 375 is ideal for car park decks, garage floors and bridges.

  • Good crack bridging ability
  • Mechanically resistant if broadcast
  • Watertight
  • Easy application
  • Solvent free


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 levelling 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 levelled 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 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.
