Concrete Polishing & Sealing proposal 21-031, Apr 1, 2021. There were two components to their work on the basement level of our spa facility. The first was to overlay a previously finished section of floor. After one redo and proper clean-up, the finished floor coating was satisfactory. The second component involved sealing and coating a smaller bare concrete floor in our pool/shower area. The coating process started from bare concrete and required the application of several layers of material. This work was done in May 2021. Unfortunately, the floor finish and clean up were unsatisfactory. The clean-up in the pool area has not been completed despite numerous calls, emails and on-site meetings. There are still stains on the tile around the base of our plunge pool. Secondly, the top flooring layer was to have a slip-resistant coating to reduce slipping on the wet floor around the pool. Any grit added by the contractor was not adequate and we have had to add our own grip tape to make sure the floors are slip-resistant. Thirdly, almost immediately following the final layer application, a wavy appearance was evident. Then small bubbles or blisters began to appear all over the floor. This was reported to the contractor. At an on-site meeting in June 2021, the contractor argued that “hydrostatic pressure” from underneath must have caused the bubbles. The contractor said the concrete had been tested for moisture before the application and this should have confirmed whether any extra treatment would be required before applying the floor covering. Our research, input from a flooring specialist and the material supplier indicate that product or improper application likely caused the bubbles. Architect's deficiency report - Bubbles and Paint Chipping on flooring; incorrect method or finish applied causing issue. To date, the contractor has refused to do a proper clean up or correct the bubbling. They have offered $300 to go towards cleaning. They were paid over $9000.
