Ceramic Tile in San Francisco |
Old Technology
Acid Etching
Hydrofluoric Acid was used to “etch” or rough up the surface of the bathtub, which would then help the coatings to stick to the porcelain bathtub or tile. If this material is mishandled, it can cause damage to fixtures, floor tile or burns on the skin of the technician.
New Technology
Adhesion Promoter
Bonding agents are a type of “super glue”. When this “super glue” is applied to the surface of the bathtub, the new coating will be chemically fused to the surface of the bathtub. This process has proven to be the best method to allow coatings to adhere to the surface and is less likely to peel. American Grout Specialists use a specially designed Power Bond to ensure maximum adhesion.
Steps to Refinishing a Bathtub or Tile Area
The bathtub is scrubbed clean with a powerful detergent that will remove any soap film build-up or residual film left behind by household cleaners.
The tub is rinsed and dried completely using a high temperature heat gun or air hose to remove all moisture with special attention placed on the drain area and the area where the tub meets surrounding tiled walls.
Paper masking is installed around the tub to prevent over spray from getting on the tiles. Other areas of the bathroom will be masked off with plastic, as necessary.
The Power Bond agent is then applied to the surface of the tub or tile.
Slip resistant surface is applied to the floor of the tub (if desired).
A High Gloss Acrylic Urethane topcoat is applied with an HVLP spray gun resulting in a durable surface that will last for years and will not yellow.
A ventilator is used which helps remove over spray and fumes from the bathroom area. It pulls the air from the room and with it, the over spray and dust particles.
This piece of equipment is placed in the window of the bathroom, or if there is no window in the bathroom, a hose is attached and directed to the nearest window or door.
