What is the difference between waterproof sealant and silicone sealant?

Waterproof sealants are specifically formulated to prevent water penetration, making them ideal for sealing joints and gaps in areas prone to moisture exposure, such as bathrooms and kitchens. Silicone sealants, on the other hand, offer versatile sealing solutions for a wide range of applications, including both waterproof and non-waterproof projects. While silicone sealants can provide water resistance, they may not offer the same level of waterproofing as dedicated waterproof sealants.

Can sealant be painted over?

Yes, many sealants are paintable once they have fully cured. However, it's essential to check the manufacturer's guidelines to ensure compatibility with paint and to allow the sealant ample time to cure before painting. Some sealants may require priming or special preparation before painting for optimal adhesion and finish.

At MGN Builders Merchants, we understand the importance of quality and reliability in building sealants. That's why we stock products from trusted brands known for their performance and durability.
