No, Everbuild General Purpose Silicone is non-overpaintable. If a paintable finish is required, you will need to use a different type of sealant.
Yes, this product is ideal for sealing around baths, showers, and basins due to its waterproof nature and anti-fungal properties which prevent mould growth in damp environments.
Unopened cartridges typically have a shelf life of 12 months when stored in cool, dry conditions away from direct sunlight. Always check the manufacturing date on the packaging.
The curing time can vary depending on temperature and humidity. It typically forms a tack-free skin within 30 minutes and cures fully within 24 hours to form a permanently flexible seal.
Yes, it is suitable for sealing around worktops and laminates to create a waterproof and hygienic joint.
This product is not suitable for aquarium manufacture because it may release substances harmful to aquatic life. Aquarium sealants are specifically formulated to be non-toxic to fish and other inhabitants once cured.
Surfaces must be clean, dry, and free from dust, grease, or old sealant. For non-porous materials like glass or metal, cleaning with a solvent cleaner is recommended for best adhesion.
Ensure surfaces are thoroughly cleaned, dry, and free from dust, grease, or old sealant. For difficult surfaces like porous materials, priming may be required. Check if a solvent cleaner was used on glass or metal.
While this product contains an anti-fungal compound, severe contamination or constant high humidity may still lead to mould. Clean the affected area thoroughly and reapply sealant. Ensure adequate ventilation in the area.
Ensure the nozzle was cut to the appropriate size for the joint. Apply steady pressure on the sealant gun for a consistent bead. Smooth the bead immediately after application using a wet finger or smoothing tool.
Check the temperature; cold conditions can make silicone stiffer. Try to warm the cartridge slightly. Ensure the nozzle opening is adequately sized. The product has low viscosity for ease of application, so significant resistance may indicate other issues.
Surface Preparation:
All surfaces must be clean, dry, and free from dust, grease, and other contaminants. Remove any old sealant or flaking coatings. For glass, metal, and aluminium, use a suitable solvent cleaner to ensure optimal adhesion. Porous surfaces, such as new concrete or stonework, may require priming; test on a small area first.
Application:
Cut the nozzle to the desired bead size. Apply using a standard sealant gun. Ensure joints are correctly sized for the sealant's capabilities. Refer to joint ratio recommendations for best results.
Compatibility:
Care:
Clean up uncured excess sealant with a damp cloth or solvent. Cured sealant can be removed mechanically by cutting or scraping. For ongoing maintenance, clean the sealed area with mild detergent and water. Avoid abrasive cleaners.
