Consumption
| Joint length [m] per 300 ml | Joint width [mm] | Joint depth [mm] |
| 3,0 | 10 | 10 |
| 2,0 | 15 | 10 |
Triangular joint profiles must have sides for bonding ≥7 mm.
For larger joints, contact Sika Technical Services for additional information.
Consumption calculation formula
Length of joint [m] = 300 ml / (Joint width [mm] x Joint depth [mm])
Litres / Metre run of joint = (Joint width [mm] x joint depth [mm]) / 1000 [m x mm2 / l]
Consumption depends on the roughness and absorbency of the substrate.
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.
APPLICATION INSTRUCTIONS
SUBSTRATE PREPARATION
The substrate must be clean, dry, sound and free from oils, grease, dust and loose or friable particles. Sikacryl® AS adheres without primers and/or activators. For porous substrates, e.g. concrete, plaster and / or wood, Sikacryl® AS 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.
