Available in RAL 1014, RAL 2000, RAL 3009, RAL 5015, RAL 6010, RAL 7042, RAL 8002, RAL 9001, RAL 9005

The colour of the Sikafloor-327 has to be approximately adjusted to the colour of the Sikafloor-305 W seal / top coat.
Applied colours selected from colour charts will be approximate. For colour matching: Apply colour sample and confirm selected colour under real lighting conditions.
When product is exposed to direct sunlight, there may be some discolouration and colour variation, this has no influence on the function and performance of the floor finish.
