Product Description

Sika Sikafloor 156 Primer can be applied to concrete, cement screeds and epoxy mortars and is suitable for use indoors and outdoors.

Sikafloor 156 Primer is a 2 component, solvent-free, epoxy resin designed for interior or exterior use with Sika 2650W or Sikafloor 264 Floor Paint. Sikafloor 156 Primer offers excellent penetrative qualities for application to a variety of surfaces.

Best Uses

Sikafloor 156 Primer is best used for offering adhesion to all Sika Epoxy coatings and is ideal for use in hot and tropical climates for extra quick drying times.

Sikafloor®-156 may only be used by experienced professionals. For moisture control on cement-based substrates with moisture contents of up to 6 % CM (99% RH).
For priming concrete substrates, cement screeds and epoxy mortars. For normal to strongly absorbent surfaces. Primer for all Sika Epoxy and PUR floorings. Binder for levelling mortars and mortar screeds. For internal and external use. For substrate consolidation on concrete, cement and anhydrite screeds and refurbished substrates. For adhesion promotion for broadcast mastic asphalt and on old adhesive residues.

  • High bond strength
  • Easy application
  • Short waiting times
  • Suitable for use with underfloor heating
  • Multi-purpose
  • For external use also

Application

Sikafloor 156 Primer can be applied easily and effectively using brush, roller or squeegee for a coating that bonds excellently with high strength. The concrete substrate 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 can be damp but must be free of standing water and free of all contaminants such as 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, thoroughly cleaned with an industrial vacuum to remove cement laitance and achieve an open textured surface. Anhydrite screeds, including flowable anhydrite screeds must be ground and thoroughly cleaned with an industrial vacuum shortly before coating. Broadcast mastic asphalt must be broadcasted to excess and thoroughly cleaned with an industrial vacuum.

On fibre reinforced concrete any exposed fibres must be burnt off the surface. Weak concrete must be removed and surface defects such as blow holes 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. At least 50 % of the surface area must be cleared of residual adhesive (i.e. by grinding).

All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush or vacuum.

Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 3 minutes until a uniform mix has been achieved.
When parts A and B have been mixed, add the quartz sand and if required the Extender T and mix for a further 2 minutes until a uniform mix has been achieved. To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix. Over mixing must be avoided to minimise air entrainment.

Surface and Environment

Sikafloor 156 Primer can be applied to concrete, cement screeds and epoxy mortars and is suitable for use indoors and outdoors. For more information feel free to give us a call.
