FAQs

Can this be used on outdoor surfaces?

This product is formulated for indoor sanitary use, such as kitchens and bathrooms.

Is the white color paintable?

Generally, sanitary silicone sealants are not designed to be painted over.

How do I remove the old sealant?

Use a sharp utility knife or a dedicated silicone sealant removal tool to scrape away the old material before cleaning the gap.

Does it work on plastic surfaces?

It provides good adhesion to most hard, non-porous surfaces, but we recommend a small test patch on plastic to confirm compatibility.

Can I use this in a shower?

Yes, it is designed for sanitary areas including showers, provided it has been given the full 24 hours to cure.

Troubleshooting

Sealant is not sticking to the surface

Ensure the surface is completely free of soap scum, grease, and moisture before application.

Sealant remains soft after 24 hours

High humidity or low temperatures can slow curing. Allow extra time and ensure the room is ventilated.

The bead looks uneven

Use a specialized sealant smoothing tool or a finger dipped in soapy water immediately after application to create a uniform finish.

Resists mould and mildew growth effectively
Easy to apply without specialized equipment

Setup, Compatibility & Care

Surface Preparation: Remove all old sealant using a removal tool or scraper. The surface must be completely clean, dry, and free from grease or soap residue.
Application: Cut the tip of the tube, attach the nozzle, and trim the nozzle to the desired bead size. Apply steady pressure to achieve an even line.
Curing: Smooth the sealant with a smoothing tool or gloved finger within minutes of application. Allow at least 24 hours for the sealant to fully cure before exposing it to water. Curing times may increase if the room is particularly humid or cold.
Compatibility: This sealant is compatible with most non-porous surfaces found in kitchens and bathrooms, including tiles, porcelain, and treated worktops.
