Tips for Applying Everbuild Sealants and Adhesives
Applying your sealant or adhesive correctly is essential to ensure the best results. Here are some expert tips to help you avoid common mistakes:
- Surface Preparation: Always ensure surfaces are clean, dry, and free from dust or grease before applying any sealant or adhesive.
- Use the Right Applicator: When applying sealant, use an applicator gun for a clean, professional finish. This will give you better control and a smoother finish.
- Masking Tape: When sealing around edges or applying adhesive in tricky areas, masking tape protects surrounding surfaces and achieves clean lines.
- Allow Time to Cure: Even quick-drying adhesives need time to cure fully. Follow the product’s instructions on drying and curing times for optimal performance.
Maintenance and Longevity of Sealants and Adhesives
- Regularly inspect sealed areas, especially in high-traffic or moisture-prone spaces like bathrooms, for signs of wear, cracks, or degradation.
- Clean any mould or mildew spots immediately to prevent further damage, and reapply a fresh layer of sealant if necessary.
- For outdoor adhesives, ensure they remain strong after exposure to rain, heat, and cold, especially following extreme weather conditions.
- Conduct an annual check on exterior adhesives to maintain their integrity and ensure they continue to bond effectively.
