Because granite has various uses around the house, such as countertops or floor tiles, the specific project will determine which construction adhesive will work best for you.
The rest of this article will discuss the best construction adhesives to use on granite, the pros and cons for each product, and which products would be best for specific projects.
What Is a Construction Adhesive?
A construction adhesive is a type of glue used for attaching drywall, tile, and molding. It’s also great to use for hanging fixtures to walls and ceilings. Construction adhesives are general-purpose and can be used for various purposes around the house. They typically come in tubes and are applied with a caulking gun.
There are construction adhesives made explicitly for granite—aptly called granite construction adhesives. Construction adhesives that are best for granite can typically also be helpful on mirrors and marble surfaces.
Loctite PL 530 Mirror, Marble, and Granite Construction Adhesive
This Loctite adhesive is the best option for granite. It’s solvent-based and made specifically for application in kitchens and bathrooms. Along with granite, this adhesive works wonders on marble, concrete, fiberglass, glass, drywall, ceramic, brick, metals, tile, backsplashes, and some mirrors.
Pros
- It won’t stain or cause damage.
- It’s long-lasting in humid climates.
- It has a low Volatile Organic Compound (VOC) formulation, meaning it isn’t harmful and doesn’t have a powerful odor.
Cons
