Most refinishers use hydrofluoric acid to chemically etch a porcelain or ceramic tile surface in an attempt to make their coating stick hydrofluoric acid is so strong that it actually eats away the porcelain creating pits and a rough area for the new. The hydrofluoric acid in ips ceramic etching gel attacks quartz silicate and borate glasses as well as sanitary ceramics and various metals and alloys e g.

When mopped onto a mineral based surface such as stone porcelain or ceramic the product causes a chemical reaction that immediately starts etching the tile. Etching acid is corrosive. The beauty of this product is that it will never peel fade flake or need to be re applied like a coating will because it s an acid based etching not a coating. For detailed glass etching instructions and information about the materials i used see my pi e plate project tutorial.

You cannot acid etch wooden or vinyl floors. How to paint ceramic tile. Frequently the restoration is etched in the laboratory. Etching works on glass ceramic porcelain concrete and marble.

Nickel copper polyethylene pvc and teflon are resistant to hydrofluoric acid. Armour etch etching cream. Acid etching is only appropriate for concrete tile and ceramic tile. The etching process involves applying an acidic substance typically a cream to the tile and waiting for the reaction to occur.

What you need glossy finish ceramic tile. The etching process removes the glossy glaze layer leaving a rough ceramic layer perfect for coloring. If the restoration is etched in the laboratory do not re etch in the office with 5 hf. Acid etching ceramic restorations prior to bonding is essential in order to create the appropriate surface structure needed to maximize retention of the resin cement.

This study assessed the effect of pretreatment of hybrid and glass ceramics using a self etching primer on the shear bond strength sbs and surface topography in comparison to pretreatment with hydrofluoric acid and silane. These results could be explained by insufficient micro depths of the irregularities formed by high er yag laser power settings which resulted in limited penetration of silane and low sbs. 2011 ceramic tile institute of america. Etching a second time is.

Increased surface roughness by the acid etching effect of hf treatment resulted in good adhesion between the ceramic and cement while 600 and 900 mj lased specimens exhibited poor adhesion patterns. 40 rectangular discs from each ceramic material ips e max cad em vita mark ii vm vita enamic ve were equally divided n 10 and assigned to one of four.
