Product Information
Full details
The Everbuild Everflex 200 Contractors Silicone in Translucent is a cost-effective, acetoxy cure sealant ideal for general waterproofing, sanitary, and gap sealing applications for both interior and exterior use. Its key benefit is providing a permanently flexible, watertight seal with anti-fungal properties to prevent mould growth, making it excellent for high-humidity areas like bathrooms and kitchens. A caveat to consider is its acetoxy cure, which releases acetic acid and may not be suitable for all sensitive materials or unpainted surfaces where acid etching could be a concern.

FAQs
What does 'acetoxy cure' mean?
Acetoxy cure means the sealant releases acetic acid (vinegar smell) as it cures. This method provides good adhesion and quick curing on non-porous surfaces but can be corrosive to some metals and alkaline materials. It's generally not recommended for natural stone due to potential etching.
Is this silicone suitable for exterior use?
Yes, the Everbuild Everflex 200 Contractors Silicone is suitable for both interior and exterior applications, offering a durable and waterproof seal against weather elements.
How long does it take to cure fully?
The curing time depends on temperature, humidity, and bead size. Typically, it forms a skin within minutes and can be handled within 1-2 hours. Full cure, to achieve maximum adhesion and water resistance, usually takes 24-48 hours.
Can I paint over this silicone sealant?
No, silicone sealants are generally not designed to be painted over. Paint typically adheres poorly to silicone. If a painted finish is required, consider using a paintable sealant or ensure the silicone is applied only where it will remain visible.
What is the flexibility range of this sealant?
This sealant offers a flexibility of +/- 12%, meaning it can accommodate joint expansion and contraction up to 12% of the joint width without losing its integrity.
How do I remove uncured silicone sealant?
Uncured silicone can usually be wiped away with a cloth dampened with white spirit. For stubborn residue, a dedicated silicone remover may be necessary.
Is this product safe for use near food preparation areas?
While it has anti-fungal properties suitable for kitchens, it is not specifically rated as food-safe. It is best to avoid direct contact with food and use food-grade sealants in areas where this is a concern.
Troubleshooting
Sealant not sticking to the surface.
Ensure surfaces are thoroughly cleaned, dry, and free from dust, grease, or old sealant. Degrease non-porous surfaces before application.
Sealant is too difficult to apply (very stiff).
Check if the product has expired or been stored incorrectly. Ensure you are using a suitable, high-quality sealant gun. Low temperatures can also increase viscosity; try warming the cartridge slightly.
Uneven or messy sealant bead.
Practice applying a consistent bead on a scrap surface. Ensure the nozzle is cut correctly for the joint size. Use a smoothing tool immediately after application for a professional finish.
Sealant peeling away after curing.
This often indicates poor surface preparation or incompatibility with the substrate. Re-apply after thorough cleaning and ensure compatibility with the surface type.
Mould growth appearing on the seal.
While the product has anti-fungal properties, persistent mould may indicate inadequate ventilation or excessive moisture. Clean the affected area with a mild bleach solution and ensure better ventilation.
Pros and Cons
Pros
Cost-effective solution for general sealing needs.
Excellent adhesion to smooth, non-porous materials like glass, ceramics, and PVCu.
Effective anti-mould properties for hygiene in damp areas.
Quick curing time speeds up project completion.
Maintains flexibility to accommodate building movement.
Cons
Acetoxy cure releases acetic acid, which can affect certain materials (e.g., some metals, natural stone).
Not ideal for porous surfaces without proper priming.
Translucent colour may not match all aesthetic requirements.
Low to mid modulus may not be suitable for very high movement joints.
Can be susceptible to dirt pick-up over time, despite low initial pick-up.
Setup, Compatibility & Care Instructions
Setup:
Ensure the surfaces to be sealed are clean, dry, and free from dust, grease, and any loose material. For best adhesion, degrease non-porous surfaces.
Cut the nozzle at an angle to achieve the desired bead size. Screw the nozzle onto the cartridge.
Place the cartridge into a standard sealant gun.
Apply a consistent bead of silicone sealant along the joint.
Smooth the bead immediately using a wet finger, spatula, or smoothing tool for a neat finish. Remove excess sealant.
Allow the sealant to cure fully before exposing it to water or heavy use.
Use with caution or avoid on: Porous surfaces (e.g., unpainted wood, brick, concrete) unless primed appropriately. Due to its acetoxy cure, avoid contact with reactive metals (like lead, brass, copper) and alkaline surfaces (like concrete, render) as it may cause discolouration or corrosion. Not recommended for use in food contact areas.
Care:
Clean any uncured residue immediately with a cloth dampened with white spirit. Cured sealant can be removed mechanically or with a silicone remover.
The cured sealant can be cleaned with mild detergent and water. Avoid abrasive cleaners.
