DIY bathtub refinishing gone bad.
Two years before the home owner contacted Renew, they had thier bathroom beautifully remodeled. New vanity, sink, toilet and tile. They purchased a DIY tub refinishing kit from a local big box store. While the finish was not as smooth and glossy as a professionally refinished bathtub it was much better looking than the existing pink tub. The biggest problem was that the finish just didn't have the adhesion and durability that can only be achieved through the professional methods.The old finish needs to be removed with a chemical stripper. Depending on the quality of the previous finish this can take anywhere between 1-2 hours. There have been some very rare instances that this procedure has taken 6 hours.

The most important process! After the tub is stripped or if the tub has never been refinished before we remove all the caulking around the bathtub. We then use a 4 part cleaning process.
First, we use an alkaline cleaner to remove all soap scum, body oils and conditions.
Second, an acidic cleaner is used to deep clean the tub to remove any lime scale, rust or hard water deposits..It is also designed to etch the tub to give the perfect profile for our Silane bonding agent to adhere to. Our cleaner contains no Hydrofluoric Acid.
Third, we wash the tub down again with the alkaline cleaner.
Forth, the tub is cleaned with a solvent to catch anything we might have missed.
After the bathtub is fully cleaned we apply a Silane primer to the tub. This blend is designed to have both a molecular and mechanical bond to the original tub surface.
Once the primer is dry we apply the SRS Floor. The Slip Resistant Surface Floor is designed to be like a built in bathmat yet blend with the new tub finish. This is achieved by mixing a fine polymer into the coating and rolling it out on the bathtub floor.
Next is the fun part.
Apply the top coat of high performance aliphatic urethane gloss finish. Normally this consists of three coats. Depending on the condition, additional coats might be added. The number of coats applies varies on environmental conditions. The end goal is to achieve the proper thickness
