Question 1

What is Henkel Polybit Polyseal PS GG COLOR Polysulphide Sealant 2.5L?

Accepted Answer

Henkel Polybit Polyseal PS GG COLOR is a two‑component polysulphide sealant designed for building construction and industrial joints. It comes in a 2.5 L cartridge and is available in multiple colors to match surrounding materials.

Question 2

Which surfaces does this sealant bond to?

Accepted Answer

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

Question 3

What are typical use cases for this sealant?

Accepted Answer

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

Question 4

How do I apply Polyseal PS GG COLOR?

Accepted Answer

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.

Question 5

What color options are available for this sealant?

Accepted Answer

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

Question 6

What performance characteristics does it offer?

Accepted Answer

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.

Question 7

How long does it take to cure, and when is the joint serviceable?

Accepted Answer

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.

Question 8

Is this sealant safe to use indoors and outdoors?

Accepted Answer

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.

Question 9

How should I clean tools and surfaces before and after application?

Accepted Answer

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.

Question 10

How should I store the product to maximize shelf life?

Accepted Answer

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.

Question 11

How does polysulphide compare to other sealants like silicone or polyurethane for joints exposed to moisture?

Accepted Answer

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.

Question 12

What should I consider when choosing this product for my project?

Accepted Answer

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.
