Triangular joints (where the sides of the joint meet at a right angles) must have sides for bonding ≥7 mm.

Consumption calculation formula

Length of joint [m] = 300 or 600 ml / (Joint width [mm] × Joint depth [mm]) Litres / Metre run of joint = (joint width [mm]× joint depth [mm]) / 1000 [m × mm2 / l]
Application steps

SUBSTRATE PREPARATION

The substrate must be clean, dry, sound and free from oils, grease, dust and loose or friable particles. Sikacryl® S adheres without primers and/or activators. For porous substrates, e.g. concrete, plaster and / or wood, Sikacryl® S can be dissolved in water (1:1 to 1:5 ratio) and used as a primer if necessary. On plastics and paints, adhesion tests must be carried out prior to application. Iron and steel must be protected with an anti-corrosion primer.

MIXING

1-part ready to use

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
