CERESIT CT 87 White Flexible | Fibre-reinforced base coat mortar

Ceresit CT 87 is the white, fibre-reinforced mortar of the Ceresit Ceretherm Premium system: it is used both for fixing EPS and stone wool (MW) boards, and for creating the reinforced layer with glass fibre mesh — with significantly lower consumption per m² than the other mortars in the Ceretherm range. Its special white colour and organic modifiers mean that the priming stage can be omitted before applying decorative render.

ARGYNET LAB: CT 87 combines two advantages that rarely go hand in hand: lower material consumption per m² (cost savings) and premium-level technical performance (Fibre Force — impact resistance, resistance to hairline cracks, flexibility). It works on both EPS and stone wool, just like Thermo Universal, but with the added advantage that — thanks to its white colour — there is no need for a CT 16 primer before applying a light-coloured decorative render. This saves an entire work step and reduces material usage on site. At ARGYNET, we recommend it for projects where speed of completion and control of material costs are a priority.
