Exterior sealants for weatherproof joints
Exterior joints must manage rain, sunlight, temperature changes and movement without losing adhesion or allowing water into the building envelope.
This guide connects weatherproofing applications with Resibond products for ACP, glazing, curtain walls and building perimeters. Joint design, backing material, primer requirements and movement capability must be verified before specification.

Frequently asked questions
Questions about weatherproofing.
Which Resibond sealant is intended for weatherproofing?
Weather 5010 is the primary product for exterior weather sealing, façades, curtain walls and exposed glazing.
Can general-purpose silicone be used for façade joints?
Do not assume general-purpose products meet façade movement or durability requirements. Use a product and joint design verified for the actual exposure.
Does every exterior joint require primer?
Primer requirements vary by product and substrate. Conduct an adhesion assessment and follow the latest TDS and project specification.
