I recieved a Sample of the product and my first test with it I didnt care for it......What I found was that is shrank some resulting in low joints..........Recently I tried another batch on another board and this time it reacted quite differently..........This leads me to believe I may have recieved a Bad batch........BUT I am not ready to make any conclusions YET.
Rich, I have 80 4x5x9 Showers and several Large Public restrooms that we will be grouting with Quartzloc Grout along with a Pile of wall tile around a complete Waterpark and by the time I finish these I expect I'll be If not an Authority on the product, Pretty dang knowledgable about its characteristics good and Bad........
At that time I will make My Overall Assessment right down to giving a Dollar figure (as both dollar amount and s/f Percent increase amount) for upcharge Based on the amount of additional time required to complete the grouting in a satisfactory manner.This will make it possible to create your own dollar figure Based on your area's going rate.
I should also be able to determine a Percentage of what I'll call applicating failure: The shrinking of the product resulting in a necessary second application. Several Tiles of Various sizes and Joints of various sizes will be used so it will be a Very thorough proving ground. This percentage can then be figured into your Extra pricing should it prove to be a factor.
with nearly 15,000 s/f I would think nearly all possible scenarios that could happen will be discovered.
Look for this report around the 1st week of May or thereabouts
