Product Description

"POLYBIT® Polyseal 1PU is a one part low modulus high performance polyurethane sealant, which cures on absorption of atmospheric moisture to form a firm and flexible rubber watertight seal for moderate movement and control joints. Polyseal 1PU can be used in both horizontal and vertical applications. The sealant has a Movement Accomodation Factor (MAF) of ±25%."

Highly resilient with excellent recovery characteristics
Provides permanent and uniform watertight seal
Excellent adhesion to most building substrates.
Non-toxic. Can be used in potable water reservoirs and swimming pools
Easy to apply, one component sealant. No mixing required
Overpainting can be done (Rigid paints may crack)

How to Use

Joint preparation

The joint edges must be clean, dry and free from oil, loose particles, cement laitance and other contaminants which may affect the adhesion. A thorough wire brushing, grinding, sand blasting or solvent cleaning may be required to expose a clean and sound substrate.

Priming

On new substrates, the sealant can be applied without Primer.However, for old and very porous substrates apply Polyprime PS*. When applying on aluminium and metal surfaces, ensure the surface is cleaned of all lacquer or protective coatings.

Back-Up Material

A bond breaking backing rod (Polyrod)* shall be inserted into all movement joints to avoid a three sided adhesion. A bond breaking tape may be applied to joints where the depth does not allow the application of the backing rod.
