Hello Support, I hope this message finds you well. I had contracted a Painting(Garage & Laundry room and Garage Epoxy Flooring) to a local contractor in Florida (Brevard County). The total cost of the project was about $1850 dollars. The scope of the project outlined in the initial estimate was not followed precisely, but I choose to follow the contractor's professional advice. The issues that arise stem mainly from the epoxy part of the job, having several air pockets on the floor resulting from epoxy not adhering properly. After having a call with Sherwin Williams(Brand of Expoy used) agent, she advised that epoxy should not be poured onto fresh concrete or should be given weeks of drying time before doing so. The pouring of fresh concrete was not part of the scope of the project and it replaced 'repairing of cracks' and acid washing and scoffing the concrete. Anyway, the contractor dealt with all of my objects and the job became almost salvageable. The final aspect of adding the prescribed amount of clear coat (3) was not done in a timely fashion or as per the product specification required. Sherwin William's brand of epoxy clear coat requires additional coats to be added before 72 hours window. Here is the contractor took weeks to respond back to my message after I advised him that I'll get someone else to do finish or redo the job. He finally replied and hurried someone to come finish the job. I told him no one is touching the job unless the specification of Sherwin William is followed;re-scoff before adding clear coat since it was way beyond the application window. He then threatened a Lien on the property via Text. However, we came to an agreement that if he would take the risk of adding the clearcoat and everything turn out favorable after 72 hours he will be paid and so far the finish looks fine. Now before paying him, I need a legal instrument that would protect me from any future threats, and so i was looking at your conditional waiver. Is this the right legal instrument to use? Be advised I've already given him a 50% advance payment as well. Thanks Regards
