Product Information

Full details

Bond It WP100 is a premium neutral cure oxime silicone sealant designed for professional contractors and serious DIY enthusiasts who require a durable, weather-resistant finish for construction projects. Its primary benefit is its high elasticity and long-lasting bond strength, making it ideal for movement-prone joints around windows and doors; however, users should be aware that the fast cure rate requires efficient and precise application to ensure a smooth finish.

Extended Product Information

FAQs

Can I use WP100 on natural stone?

It is generally not recommended for natural stone as silicone oils can sometimes cause staining on porous surfaces.

Is this product paintable?

No, silicone sealants are not paintable. You should ensure the color match is appropriate for your project before applying.

How long does it take to fully cure?

While it skins in 5-10 minutes, full cure depth depends on the joint width and environmental conditions, typically reaching full strength within 24-48 hours.

Does this require a primer?

Bond It WP100 generally provides excellent adhesion to most clean, non-porous surfaces without the need for a primer.

Is it safe for internal use?

Yes, but ensure the area is well-ventilated during application as the neutral cure process releases a small amount of byproduct during the initial stage.

Troubleshooting

Sealant is not sticking to the surface

Ensure the substrate is completely free of grease, dust, or residual old sealant. Clean with a solvent-based cleaner if necessary.

Sealant is skinning over too fast while tooling

Work in shorter sections or ensure the ambient temperature is not excessively high, which accelerates the curing process.

Bubbles or voids in the seal

Apply consistent pressure on the caulking gun trigger to maintain a uniform flow and prevent air entrapment.

Pros and Cons

Pros

  • Excellent adhesion to multiple substrates
  • High UV and temperature resistance
  • Mould-resistant for long-term cleanliness
  • Neutral cure is non-corrosive to metals

Cons

  • Rapid cure time leaves a small window for tooling
  • Requires professional application techniques for best results
  • Limited color availability

Setup, Compatibility & Care

To prepare for application, ensure you have a standard caulking gun and a sharp nozzle cutter. Cut the nozzle at a 45-degree angle to the desired bead size. Always test adhesion on an inconspicuous area if working with specialized architectural coatings.

Compatibility includes:

  • Suitable: PVCu, glass, aluminium, steel, and most non-porous construction materials.
  • Avoid: Natural stone that may be stained by silicone oils, or structural glazing applications unless specified by the manufacturer.

For care and maintenance, avoid using harsh abrasive cleaners on the cured silicone. If the seal becomes damaged, cut out the affected area, clean thoroughly, and reapply following the same preparation steps.
