Henkel Polybit Polyseal, PS GG Colour Polysulphide Sealant, 2.5L, Durable Polysulphide Joint Sealant

It adheres well to concrete, masonry, wood, metal, and other common construction substrates when surfaces are clean and dry.

It's suited for sealing building joints, expansion joints, and perimeter sealing where a flexible, weather‑resistant seal is needed.

Load the two components into a caulking gun, mix them thoroughly until uniform, cut the nozzle to the desired bead size, apply in a continuous bead, and smooth the joint after application. Ensure the joint surfaces are clean and prepared for adhesion.

Polyseal PS GG COLOR is offered in a range of colors to help match or complement surrounding materials.

It provides strong adhesion to various substrates, excellent elasticity and flexibility to accommodate movement, and resistance to water, weather, and UV exposure for durability in exterior and interior environments.

Cure time depends on factors like joint thickness, ambient temperature, and humidity. The sealant cures gradually and reaches higher cure levels over days; for precise cure times, follow the product data guidance on the package and technical datasheet.

Yes. It is suitable for both indoor and outdoor applications. Use in well‑ventilated areas, wear appropriate PPE (gloves, eye protection), and avoid skin or eye contact.

Clean tools with an appropriate solvent (such as mineral spirits) before the sealant cures. Once cured, sealant removal typically requires mechanical methods or specialized solvent systems as recommended by the manufacturer.

Store in the original, tightly closed container in a cool, dry place out of direct sunlight. Keep away from extreme temperatures and moisture to maintain performance.

Polysulphide sealants provide good elasticity, strong adhesion to a variety of substrates, and excellent moisture resistance, making them well suited for joints that move and are exposed to water. Silicone sealants generally offer superior water resistance and UV stability but can be less flexible in dynamic joints, while polyurethane sealants often deliver strong adhesion and durability but may have different moisture curing characteristics. Choosing the right option depends on joint movement, exposure conditions, and substrate compatibility.

Consider joint movement range, exposure to moisture and UV, substrate types, color matching requirements, and the desired working life. The 2.5 L pack is well‑suited for medium to larger joint projects and color coordination with surrounding materials.
