FAQs

How long does the sealant take to dry?

The sealant needs at least 24 hours to dry fully. This duration can be longer depending on the size of the bead applied, the surrounding temperature, and humidity levels. Protect the area from water during this time.

Can this sealant be painted over?

Silicone sealants are generally not paintable. For areas that require painting, consider using a paintable caulk or sealant product.

What surfaces can I use this sealant on?

This Unibond sealant is ideal for use on tiled areas, bathrooms, kitchens, worktops, and sanitary ware. Ensure surfaces are clean and dry before application.

How do I remove old sealant before applying new?

Carefully cut away old sealant using a sharp blade or a dedicated sealant removal tool. Clean the area thoroughly to remove any residue and ensure it is completely dry before applying the new Unibond sealant.

Is this sealant suitable for outdoor use?

The product description focuses on indoor kitchen and bathroom applications. For outdoor use, it's best to consult Unibond's product range for sealants specifically rated for exterior conditions and UV resistance.

What precautions should I take when using this product?

Ensure good ventilation during use. Avoid contact with skin, as it may cause an allergic reaction. Wear gloves. This product is toxic to aquatic life with long-lasting effects, so avoid release into the environment and dispose of waste responsibly.

How many tubes are in this pack?

This pack contains three tubes of Unibond Silicone Sealant, each weighing 147g.

Troubleshooting

Sealant not sticking or peeling off

Ensure the surface is completely clean, dry, and free from dust, grease, or old sealant. Reapply ensuring proper surface preparation.

Uneven or messy application

Practice applying with a sealant gun on scrap material. Use a sealant finishing tool and smoothing agent within 5 minutes of application for a clean edge. Remove excess uncured sealant promptly.

Sealant remains sticky after 24 hours

This can be due to high humidity, low temperatures, or a very thick bead. Ensure application conditions are within the recommended range and allow additional drying time. Avoid disturbing the sealant during this period.

Mould returning quickly

While the sealant is anti-mould, ensure thorough cleaning of the original mould source before application. Maintain good ventilation in the area to inhibit future growth.
