Question 1

What is Henkel Polybit Polyseal PS PG Polysulfide Sealant 4L and what is it used for?

Accepted Answer

Polybit Polyseal PS PG is a versatile one-component polysulfide sealant designed to provide durable, flexible sealing in demanding environments. It is suitable for joints and gaps in indoor and outdoor applications, offering long-term joint protection, resistance to moisture, saltwater, and solvents, and can be painted after curing.

Question 2

Which substrates does it bond to best?

Accepted Answer

It adheres well to wood, metal, plastic and concrete. For some substrates or primed surfaces, a primer may improve adhesion; always test a small area if you’re unsure.

Question 3

What are the key performance features of this sealant?

Accepted Answer

Key features include high elongation and flexibility, moisture-curing capability, resistance to extreme temperatures, saltwater and solvents, no solvents or isocyanates, ozone resistance, and paintability with a variety of color options.

Question 4

Is Polyseal PS PG paintable, and what color options are available?

Accepted Answer

Yes, it is paintable once cured, allowing you to match or integrate with your project colors. It is available in a variety of colors to suit different applications.

Question 5

How do I apply and cure this sealant correctly?

Accepted Answer

Surface should be clean, dry and free of old sealant. Cut the nozzle to the desired bead size, load into a caulking gun, apply a continuous bead, and tooling should be done while the material is still fresh. Cure occurs via moisture in the air; cure times depend on temperature and humidity, typically progressing to a tack-free state and full cure over 24–48 hours or longer depending on conditions.

Question 6

Do I need to prime substrates before applying Polyseal PS PG?

Accepted Answer

Priming may be required for certain substrates to optimize adhesion. For porous or challenging substrates, testing a small area first and following substrate-specific guidance is recommended.

Question 7

What surface preparation steps should I follow?

Accepted Answer

Thoroughly clean the surface, remove dust, grease and old sealant, and ensure the area is dry. Roughening very smooth substrates can help adhesion, and any contaminants should be fully removed before application.

Question 8

What safety and environmental considerations should I know?

Accepted Answer

Work in a well-ventilated area and wear appropriate PPE such as gloves and eye protection. The product is designed to be solvent-free and free of ozone-depleting substances, but always consult the SDS for detailed safety information and proper disposal guidelines.
