Gap Filla is a high-quality acrylic gap sealant specifically formulated to provide a flexible and durable seal in various construction and renovation projects. Its unique formulation allows it to accommodate minor movements without cracking, making it ideal for joints where flexibility is required. Gap Filla's excellent adhesion to a wide array of substrates, combined with its paintable surface and easy water clean-up, makes it a preferred choice for both professional and DIY users.
Gap Filla is formulated to provide a smooth, consistent paste that is easy to apply and tool. Its acrylic polymer base ensures flexibility and durability, while its water-based formulation allows for easy clean-up. Gap Filla is designed to cure through water evaporation, forming a flexible seal that can withstand minor movements.
Chemical Properties: Acrylic Polymer, water-based.
Application Temperature Range: +5°C to +35°C (41°F to 95°F). Ensure surfaces are clean, dry, and free from contaminants before application.
Q: Can I use Adheseal Gap Filla to fill gaps in an outdoor undercover patio area?
A: Adheseal Gap Filla can be used in sheltered exterior locations, like an undercover patio, provided it's not directly exposed to heavy rain or prolonged dampness. For best results in such areas, ensure it is fully cured and then well-painted with a quality exterior paint to provide additional protection against weathering and moisture. For fully exposed outdoor joints, a more weather-resistant sealant like Adheseal ProFlex or a silicone sealant would be more appropriate.
Q: How wide a gap can Adheseal Gap Filla effectively fill?
A: Adheseal Gap Filla is best suited for gaps up to approximately 10mm wide and 10mm deep. For significantly larger gaps or deeper voids, it's recommended to first use a backing rod or fill the bulk of the void with a suitable backing material before applying Gap Filla as a finishing sealant. This ensures proper curing and prevents excessive shrinkage.
Q: Is Adheseal Gap Filla mould resistant for use in a laundry or kitchen?
A: While Adheseal Gap Filla is primarily for general interior gaps, it does not contain specific potent fungicides for high-humidity areas. For areas prone to mould and mildew like bathrooms, laundries, or kitchen splashbacks, it's better to choose a dedicated sanitary silicone sealant (e.g., Adheseal Kitchen & Bathroom Silicone) which contains fungicides to inhibit mould growth. Gap Filla can be used for dry area gaps in kitchens/laundries that will be painted.
Q: How long do I really have to wait before painting over Gap Filla? The TDS says 24-48 hours.
A: 24-48 hours is a general guideline for full cure under typical conditions (25°C, 50% RH, moderate bead size). The sealant should be firm, dry to the touch, and not easily dented. In cooler or more humid conditions, or with larger beads, full cure may take longer. Painting too early, especially with solvent-based paints, can lead to paint cracking or poor adhesion. If unsure, it’s always safer to wait a little longer, especially in winter.
Q: Can I use Gap Filla to seal around tiles in a dry area, like a decorative tiled skirting?
A: Yes, Adheseal Gap Filla can be used to seal the top edge of decorative tiled skirtings or similar dry, tiled areas against a wall before painting. It adheres well to ceramics and can be painted to match the wall. However, it is not a tile grout and should not be used to fill joints between tiles, especially in floor or wet area applications.
