About Polished Porcelain
Porcelain is pressed dust, i.e. the raw materials are ground, mixed and moistened; literally pressed into the desired shape using tremendous force, creating a ceramic tile with a very low absorption level and high mechanical strength and chemical resistance.
Vitrified / vitreous tiles are usually very hard for liquids to penetrate, but polished porcelain usually stains and absorbs water quite easily.
Even with dense vitrified tiles, it is always a good idea to seal tile grout, as this is usually the easiest pathway for water to get in and cause damage - in the shower for example. Once water gets underneath tiles, it is often free to move through concrete floors, brick and mortar walls, and to rot wooden structures.
Sealing Polished Porcelain
Polished Porcelain is usually prone to staining and water ingress. All polished porcelain should be sealed for protection. Polished porcelain tiles usually arrive with some type of wax coating (which protects it during shipping) - this wax coating must be thoroughly cleaned off prior to sealing.
To maintain the look, breathability and slip resistance of polished porcelain, it is important to use a high quality, invisible impregnating sealer. Dry-Treat impregnating sealers are safe and suitable for outdoor and indoor surfaces, and for residential or high traffic commercial surfaces.

1) Any surface to be sealed should be clean and looking just as you want it before it is sealed - it may be impossible to remove stains after sealing.
2) The surface must be freed waxes or other topical coatings. Any such existing coating must be removed prior to treating with a Dry-Treat sealer.
3) Ensure the material is thoroughly dry before applying any Dry-Treat sealer.
HANAFINN Oxy-Klenza™ is a highly effective, heavy-duty cleaner which is safe to use on most types of porous surface. HANAFINN X-Duty Graffiti Kleena™ may also be used for stubborn stains and is also an effective wax remover.
Bleach diluted with water (1 part bleach to one part water) may also be used for stubborn stains. Apply the diluted bleach to the stained area, let it sit for 1-2 minutes, agitate with brush or cloth and then rinse well with clean water.
1) Always test any cleaning chemical or sealer on a small, inconspicuous area of the surface 24 hours before doing the project, to check that it will produce the desired result. This is especially important with ENHANCE-PLUS™ to ensure the colour enhancement is what you want.
2) Always ensure the surface is completely dry before proceeding with sealing.
