MS Flexseal hybrid sealant Universal hybrid sealant

A correctly dimensioned joint is able to absorb movement between construction materials. The depth of the joint should always be in the correct proportion to the width of the joint. As a general rule, the ratio between the depth of the joint and the width of the joint, for a joint width of up to 10 mm, is 1:1 with a minimum of 5 mm in width and depth. On joints wider than 10 mm, the depth is the width divided by 3 plus 6 mm. Processing temperature +5 °C to +40 °C (environment and substrate). Surfaces must be dry, clean and solid. Clean surfaces with Würth cleaner. This product adheres perfectly without a primer on the majority of non-porous substrates. Special types of porous substrates may need to be pre-treated with a suitable Würth primer. Always test the adhesion before application. Use Würth finisher to smooth the joint.
