The sealant delivers the flexibility and durability associated with silicone while maintaining the ease of an elastomeric latex base. It handles joint movement and seals openings up to 2 inches wide, making it useful for larger seams. It adheres to a broad assortment of common materials, including wood, PVC, MDF, polystyrene, and composite trimboard.
For projects on a tight timeline, this 100% waterproof sealant can be painted over just two hours after application. The main consideration is that this specific cartridge comes in a pre-tinted Clay color, meaning you will likely need to paint over it if your surrounding surfaces are white or another finish.
