The customer had a large, acrylic imitation marble jacuzzi tub in their master bath. It was a light blue and white swirl.
The preparation is similar to fiberglass refinishing. All the trim (brass color) was taken off so as to get area behind them coated (taping leaves potential problems). We use a finer grit (220) to dull the finish.after which chips are repaired and tub is vacuumed several times. The brass trim is converted to white like the tub. This metal is prepared by solvent wash (lacquer thinner) and 500 grit. Some customers want the trim matched to faucette choices (pewter,nickel,etc...)
After covering up and taping we applied same resin as we use for fiberglass and porcelain. Fumes were exhausted out bathroom window.
