APPLICATION INSTRUCTIONS
For the application of SikaBond®-234 Maxtack all standard construction guidelines apply.
SUBSTRATE PREPARATION
The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles. Paint, cement laitance and other poorly adhering contaminants must be removed. SikaBond®-234 Maxtack adheres without primers and/or activators.
Non-porous substrates
Aluminium, anodised aluminium, stainless steel, PVC, galvanised steel, powder coated metals or glazed tiles have to be cleaned and pre-treated using Sika® Aktivator-205, wiped on with a clean towel. Before sealing, allow a flash-off time of > 15 minutes (< 6 hours).
Other metals, such as copper, brass and titanium-zinc, also have to be cleaned and pre-treated using Sika® Aktivator-205,wiped on with a clean towel. After the necessary flash-off time, use a brush to apply Sika® Primer-3 N and allow a further flash-off time of > 30 minutes (< 8 hours) before sealing the joints.
Porous substrates
Wood has to be sanded, concrete and mortar have to be scrubbed and sanded to remove laitance.
Clean with an industrial vacuum.
For more detailed advice and instructions please contact our Technical Service Department.
CLEANING OF EQUIPMENT
Clean all tools and application equipment immediately after use with water. Once cured, residual material can only be removed mechanically.
