New home purchased October 2014. Very poor concrete finish on the three car garage floor. Builder agreed to diamond grind and coat with "Ardex". The results appeared acceptable. Summer of 2015 noted floor displayed indentations from anything that may have rolled over it and you could easily remove topcoat with a scrap of soft pine. Ardex company agreed to send a rep to sample the product and determine the cause of failure. Samples were sent to their lab and it was determined the contractor used the wrong product (Ardex Feather Finish).
After several months of "discussions" with the builder, it is now agreed that the garage contents will be moved to temporary storage, diamond grind the floor to remove the failed and/or improper topcoat and again resurface.
The contractor wants to epoxy the floor stating it will last for years. It has been noted by others that Ardex SD/M will provide a more durable and permanent floor.
To say the least, I am "very" upset over the situation and really not looking forward to having to move my entire shop and then later setup, level and recalibrate all the equipment not to mention loss of shop production during repairs.
The question is which will be the best coating for the floor? I am not as concerned over appearance as durability and safety are a priority. I don't want to face the possibility of another repair or recoat in 5 or more years. I am retired and work in the shop on a daily basis. Any advise would be most appreciated.
Thanks, Jim
