Application Instructions
> All substrates must be dry, solid and sound, free of dust and crumbling parts, oils, grease, wax, old paint and rust.
> In order not to dirty the stone tiles and slabs, it is recommended to use masking tape on the sides of the joints before applying KALEPOLYMAS.
> Cut the tip of the cartridge and screw on the nozzle which should be cut at 45° to produce a hole corresponding to the size of the joint.
> Insert the cartridge or sausage into the gun and extrude KALEPOLYMAS.
> Smooth the surface of KALEPOLYMAS with soapy water before skin formation.
> Use cord fillers appropriate to width of joint. Width of the joint should be 5-40 mm and the depth 5-20 mm
> The thickness of KALEPOLYMAS applied should be lower than or equal to the width of the joint.
> Remove the masking tape and clean the uncured KALEPOLYMAS from tools and contaminated surfaces with white spirit. Cured KALEPOLYMAS can only be removed mechanically.
> Protect the surface from washouts at least during the first 24 hours after application.
> UV lights can change the color of the product, however mechanical properties are not effected.


> For further information refer to safety data sheet.

> Store temperatures from 5°C to 25°C in original sealed packaging.
