Defects with Drywall
One of the issues with new drywall is that many surface defects are not visible until after application of the primer, and in some cases, the intermediate coat. This is not because of quality issues with the paint or its application. Latex primer sealers are flat in appearance, and deficiencies in the drywall surface can be hard to detect, particularly under low lighting conditions. However, when materials with a slight to high gloss are applied, even small defects in the drywall are very noticeable.
Improperly applied drywall and structural deficiencies in studding can cause other problems such as nail popping (pictured above). It is important to note that…
- a uniform painted finish cannot be obtained unless the filler is properly finished
- some joint fillers may have an alkali content too high for normal paint products
- some lightweight fillers are extremely porous and may require additional applications, or an extra coat of sealer or the finish coating, none of which may have been called for in the paint specs.

MPI to Move Testing to the US
At the end of December, MPI will move its coating performance lab testing operations from its Vancouver, BC headquarters to KTA-Tator, Inc., an accredited lab in Pittsburgh, PA.

KTA is certified as an Accredited Laboratory by the American Association for Laboratory Accreditation in accordance with the ISO Standard for Testing and Calibration of Laboratories… read more
