Adhesives - the glue that holds it all together

You might think that adhesives are not the most exciting thing to write or read about. Maybe not exciting, but important! The type of adhesive you use could make the difference between success and failure of your project.


As with the use of any product, the most important thing is to read the label - it will tell you right there in black and white what it is suitable for and what will not work. Here are some general guidelines for a few of the most common adhesives:

Drywall and Panel Adhesive: this type of adhesive is - as the name indicates - used for gyproc and paneling. It is usually suitable for bonding to metal or wooden studs and it can reduce sound transmission. However, for both drywall and paneling you need to apply additional fasteners like drywall screws or finishing nails to fully support the weight of the panel and prevent warping.


Landscape Adhesive: Designed for exterior use, this adhesive is most commonly used for installing caps onto landscaping blocks like Allanblock. Another application is the bonding of cement pavers. It will also bond timbers and slate, but will not work for plastics.

Foamboard Adhesive: When installing foamboard insulation (also called SM insulation or Celfort insulation) it is very important that you use the proper adhesive. General construction adhesives can burn into the foam, reducing the R value and even affecting structural integrity. Follow the instructions for installation and brace the product with mechanical fasteners until fully cured.


Subfloor and Deck Adhesive: this is a (relatively) general construction adhesive for interior and exterior use, the most common application is for subfloor. Even though subfloor is usually nailed or screwed onto the joists, using this glue in addition to mechanical fasteners will eliminate any squeaking.


Premium Adhesive: this adhesive is 100% polyurethane, ensuring a very strong bond. It will bond a variety of materials, including metal, OSB and plastic. Use this adhesive if you are looking for a reliable, strong bond.


Tub Surround Adhesive: tub and shower walls require a special type of glue, suitable for high moisture applications. When installing a tub surround it is important to follow a few crucial steps: a) make sure you apply enough glue to the panels (typically you would need about 5 tubes for a tub surround); b) take the panels off again after 5 minutes to allow the solvent to vent for about 5 minutes before putting the panels back on. This will ensure a secure bond.
