WHY POOL PLASTER CONSULTANTS:

We are not an advocate for any segment of the industry. Our job is to evaluate and report on each case without any bias. Our reports are detailed and substantiated. Trade associations, and individuals working for them, are often biased toward protecting their members interests first with little regard for the swimming pool owner, and fail to adequately substantiate their findings


PHOTO GALLERY OF SOME COMMON POOL PLASTER PROBLEMS

Spotting discoloration ("spot etch", "etching delamination") in new white plaster. This discoloration appears as white spots, streaks and blotches on plaster, often accompanied by a "greying" of the plaster in white applications. In colored (pigmented) plasters, the discoloration is more pronounced.

Although often blamed by plaster advocates on water chemistry, this discoloration is caused by plastering workmanship and materials issues.

Greying of white plaster. This discoloration appears over time, up to 3 years after plastering, and is caused by plastering workmanship and materials issues similar to those found in spotting discoloration. Water conditions and treatments do not cause this discoloration.

Delamination (bond failure)in new white plaster

Calcium scale on new white plaster

Spall ( 1/16 inch to 1/8 inch thick) in step radius of white plaster

Spalling on radius of older white plaster with copper stains


Stalactite calcium nodule on white plaster. The calcium can be seen to be "dripping" downward and attracting metal compounds from the water.

Calcium nodule in tile grout line. Many nodules of this nature can appear on replastered swimming pool plaster

Iron stains on white plaster

AN EXAMPLE OF THE IMPACT OF WORKMANSHIP ON A PLASTER FINISH

White discolorations on colored plaster installation caused by troweling with water which is not a recommended finishing practice, and is also known to permanently discolor colored plaster and concrete by lightening (whitening) the product. Please see picture on the right.

Plaster advocates attempted to blame water chemistry for causing these obvious discolorations.

This is white swimming pool plaster that has just been troweled, prior to final finishing. The pattern left by the trowel is virtually identical to the discolorations in the siwmming pool plaster in the picture on left.
