What’s the difference between standard weight, mid-weight and lightweight joint compound?

Standard weight and mid-weight joint compounds contain more latex, which improves adhesion to the gypsum board. The heavier joint compound is also more durable but shrinks more during drying. Shrinkage results in less coverage area, so you’ll end up using more mud.

Lightweight joint compounds shrink less, but because they contain additives such as perlite to reduce weight, they are not as good at adhering to the board.

When adhesion is most important, such as during taping, choose standard or mid-weight joint compound. The remaining steps can be done with any joint compound depending on personal preference.

5 frequently asked questions about choosing ready mix joint compound

Which ProForm ready mix joint compound is best for Level 1 finish?

Standard and mid-weight joint compounds, such as All Purpose and Multi-Use, have superior adhesion for securing tape to joints and interior angles.

Which ProForm ready mix joint compound can be used for Levels 2–5 finishes?

Lite Blue, All Purpose and Multi-Use all work well for applications required in each of these levels of finish. Ultimately, it’s a matter of preference — with some finishers preferring a lightweight product that is easier to sand and transport on the jobsite while others prefer a heavier, more durable product.

Which ProForm ready mix joint compound works best with a taping tool?

All Purpose and Multi-Use Joint Compound are the ideal choices when using automatic taping tools. In addition to providing superior adhesion, they also can be used for all levels of finish.

What kind of ProForm ready mix joint compound is recommended for multistory projects?

On large, multistory projects, you might prefer a lighter pail to haul around. Lite Blue Joint Compound is 30% lighter than conventional ProForm ready mix. Additionally, it is easier to spread and has less shrinkage. Remember, if you select Lite Blue, it’s best to use a mid-weight or standard weight joint compound for taping to ensure superior adhesion.

Should I use a different joint compound for each application?

No, you don’t need to use a different joint compound for each application. Choosing one that performs well for embedding tape, filling or trimming corner beads, finishing joints, spotting nails, texturing, skim coating and sanding is an option based on your preferences
