Dryzone Anti-Mould Silicone Sealant is a high-performance moisture-curing solution designed for homeowners and DIY enthusiasts looking to create durable, hygienic seals in moisture-prone areas like kitchens and bathrooms. Its primary strength lies in its specialized formula that actively resists mould and staining, ensuring a clean appearance over time. While it offers excellent flexibility and adhesion, users should note that it requires a 24-hour window for a full cure before the sealed area can be exposed to heavy water use.

No, Dryzone Anti-Mould Silicone Sealant is a silicone-based product and cannot be painted. It is designed to be used as a final, flexible finish.
You should wait the full 24-hour curing period before exposing the sealant to direct water contact.
While it is highly durable, it is specifically optimized for indoor humid environments like kitchens and bathrooms.
Silicone sealants can sometimes stain porous natural stone; always perform a small test patch in an inconspicuous area first.
You will need a standard mastic gun, a utility knife to cut the nozzle, and a smoothing tool or soapy water for finishing.
Yes, the colour is integrated into the material and is UV-stable, meaning it will not fade or yellow significantly over time.
Ensure the area is completely free of grease, soap residue, and moisture. Clean with alcohol or a specialized cleaner.
High humidity or extremely low temperatures can slow curing. Ensure the area is well-ventilated and allow additional time.
Use masking tape on both sides of the joint before application, then remove it immediately after tooling the sealant.
To use this product, you will need a standard mastic gun to dispense the sealant evenly. Begin by thoroughly cleaning the substrate to remove any soap scum, dust, or grease, as these will prevent proper adhesion. Apply the sealant in a continuous, steady bead along the joint, then use a smoothing tool or a finger dipped in soapy water to profile the edge. Once applied, the sealant will form a skin in 25 minutes. Avoid touching or applying water to the area until the full 24-hour cure cycle is complete. Store the remaining product in a cool, dry place with the nozzle capped to prevent curing inside the tube.
