Mixing ratio:

  • Clear – Part A:Part B = 1:1 (by weight)
  • Pigmented – Part A:Part B = 1.2:1 (by weight)
  • Part A:Part B = 1:1 (by volume)

Ambient air temperature: +2 °C min. / +25 °C max.

Pot Life: Approx. 40 mins at ±23oC

Curing time: Approx. 24 hrs at ±23oC

Waiting time to overcoating: Approx. 6 hours at ±23oC

Consumption: Approx. 5 – 8 m2 per litre per coat

*Consumption depends on surface profile and texture of the Sikafloor system being coated.



Prior to mixing, premix Part A mechanically until homogeneous (1-2 minutes) at low speed. Pour the Part B into the PartA/colour, mix continuously for 1 minute until a uniform mix has been achieved. Only mix as much as is likely to be used within the pot life of the product. Pot Life will be reduced by excessive or high speed mixing and by high humidity. Do not seal the lid on mixed product as the heat of reaction causes pressure build up.



Prior to application, confirm substrate moisture content, relative humidity and dew point. Apply Sikafloor®-550 PA by brush, roller or spray. Ensure that buckets and application tools are clean and dry before use. Avoid over-rolling the roller in the tray or on the floor as this encourages viscosity increase.

– First Coat:
Apply Sikafloor®-550 PA at a rate of 5-6 m2 per litre. Use of thinner is not recommended – once the mixed product becomes difficult to pour it should be discarded. If a textured or antislip surface is required apply at 5 m2 per litre and then sprinkle apply appropriate graded aggregate (e.g. 0.5mm antislip aggregate). Allow 6 hrs drying then remove excess anti-slip with broom or vacuum. High Humidity can reduce the available time for consistent application, as well as shortening the drying and cure times.

– Second Coat:
Do not apply second coat outside of recoat window (6-18 hrs). After 18 hours the floor may no longer accept a second coat without the possibility of delamination – sanding is then advised to roughen up the surface and promote inter-coat adhesion. Mix and Apply Sikafloor®-550 PA uniformly at a rate of 6-8 m2 per litre using clean bucket and mixer. Allow 12 hours cure time before subjection to pedestrian traffic, 24 hrs for vehicular traffic and 2 days before subjecting to chemicals or severe abrasion.

Note: Coverage in rates in excess of the maximum listed may result in the product failing to fully cure.



Clean all tools and application equipment with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.

Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.

Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
