Preliminary treatment

For good adhesion on teak wood a clean, dry and grease free substrate is necessary. After cleaning the wood with Simson Cleaner E the teak has to be primed with Simson Prep P. After the drying time of the pretreatment (minimum 1 hour, maximum 6 hours) MSR Deck Caulk can be applied. For adhesion on other materials than teak wood, please consult Bostik. For optimum use of the high elasticity of MSR Deck Caulk a minimum joint dimension related to the width of a deck part is recommended. We refer to the table overleaf in the Technical Data Sheet.
