What is the difference between fillers, sealants and adhesives?
Although they are often grouped together, these products are designed for different tasks.
Fillers
Fillers are used to repair holes, dents and surface damage. They are common in decorating and prep work before sanding and painting.
Sealants
Sealants are used to close gaps and create a flexible barrier against moisture, air or dirt. They are often used around baths, sinks, windows and skirting areas.
Adhesives
Adhesives are used to bond materials together. They are useful for repairs, installation work and many general DIY tasks.
When should you use filler?
Filler is usually the best choice for damaged plaster, minor wall defects, cracks and small holes left behind by screws or fittings. Many DIY users keep filler on hand for decorating prep and general repair work.
When should you use sealant?
Sealant is best for gaps where movement or moisture is an issue. Typical areas include bathrooms, kitchens, windows and joints between surfaces.
When should you use adhesive?
Adhesive is the right choice when you need to fix or attach one material to another. Some products are designed for heavy-duty bonding, while others are more suitable for light repairs or craft-style tasks.
What should you look for when buying?

Final thoughts
The best filler, sealant or adhesive depends on the job you need to complete. Before buying, think about the surface, the environment and whether you need strength, flexibility or a smooth finish for painting. DIY365 helps you compare prices on a wide range of DIY repair products in one place.
