Choosing the right product for surface preparation can make all the difference. Caulk fills and seals gaps and joints, while patching compounds repair holes, cracks and damaged surfaces.
With modern caulk formulations now offering many properties traditionally associated with sealants, understanding which product suits the job is more important than ever.
Here’s how caulk and patching compounds differ and where to use them.
When choosing a caulking gun, one of the most important features to consider is the thrust ratio. It determines how much force the gun applies to the sealant cartridge and directly affects how easily different products can be dispensed.
In simple terms, the thicker or denser the sealant, the higher the thrust ratio you'll need.
