It’s a question we often get asked here at Fixings & Powertools Center. When you’re in need of something to plug a gap or bind materials together, the huge selection of products available on the market can make the selection process overwhelming. Shelves are packed full of tubes all claiming to have the answer. So how do you pick the right one for the job without wasting time and money?
Follow our guide to help you make the right choice.
1. Sealant: forms a barrier between materials
Sealant is a substance with a close molecular structure that creates a watertight barrier, and is available in liquid, foam, powder or paste form. It is designed to close gaps between surfaces and keep out dust and dirt, while still allowing a degree of movement. This makes sealant suitable for situations where the surface requires some flexibility, such as building joints. Mastic sealants also stick materials like wood, metal and glass together.
Watch out for different classifications termed ‘low mod’ and ‘medium mod’ sealants. Low mod will stick to porous and non-porous materials, whereas medium mod is suitable for use on smooth and non-porous substrates only, such as glass and metal.
2. Adhesive: permanent bonding solution
Adhesives are often supplied in liquid form, and are designed to grip and bind two surfaces together. Different adhesives suit different materials. They solidify on application to provide a permanent and rigid bond. Less supple than sealants, adhesives are stronger, harder and generally longer lasting.
3. Filler: fills gaps and cracks
Typically used to fill holes, polymer filler or decorators’ caulk, as it’s also known, comes in a variety of forms, from powder-based to more expensive ready-mixed formulas. Although convenient, fillers can have limitations, such as being slow to dry. Aim to choose a product that won’t shrink or crack after application.
With all this said, wouldn’t it be great if there was a single product that could do all these jobs on its own? We think we have the answer.
