9310 (4.3 oz) – 55 sq. ft (average tub/tile enclosure area)

Are the ingredients organic or inorganic? Should it be disposed of a certain way?
Both. Some of the materials are inorganic (water & minerals), about 87% by weight. The rest is organic. For disposal, it should be treated as you would a latex paint.
What colors can I get?
Consumers can order the 4.3 oz and 8 oz in white and almond. The gray is available in 8 oz only. Tile Grout Coating can be tinted using Universal Tinting System for water based paints, available at most hardware stores.
Why do some directions state that the Silicone Grout Coating needs to cure 48-72 hours before applying the Silicone Grout Sealer. Can I use my shower within that time, or does it need to be completely dry for 72 hours?
In general, the longer the cure time the better. 24 hours is normally sufficient and you can use the shower after 24 hours, unless you are in a very humid environment. If the Grout Coating begins to re-solubilize when first using the shower or applying the sealer, one would need to add additional cure time. (another 24-48 hours)
Is it O.K. to allow the product to freeze?
No. It is water based and should not be frozen.
Can the coating be thinned with anything?
It should not need any thinning, but if it seams too thick, it can be thinned with a little water (maybe 5%).
Customer called saying he had applied Tile Grout Coating to new grout, he waited the allotted time to dry and then applied the Silicone Grout Sealer, again waiting allotted time to dry. After 1 week the white from the Grout Coating started to come off.
Our grout adheres best by penetrating into the grout line. When some areas have poor adhesion it is commonly due to the pores being closed due to water deposits, soap residue, previous sealer applications or some other build up. Normally, you can lightly scratch the grout to expose the original grout surface and re-apply. If the entire surface is not adhering:
1. It is most commonly due to the surface having already been sealed.
2. It is not recommended for epoxy grout, as it is non-porous.
3. A heavy amount of Acrylic latex additive is used in a new grout mix creating a sealed grout surface.
The remaining coating can then be removed with our Tile & Grout Cleaner, a scrub pad, and a plastic bristle brush. Any stubborn area may require something stronger such as our OOPS waterbased remover or a sealer stripper.
Customer claims she spent all day cleaning with a toothbrush the grout line before applying the Tile Grout Coating and when she sponged off the excess on the tiles it all came off including off the grout line.
Reason this could have happened is insufficient cleaning and also there could have been a sealer on the grout line that was not removed. If a sealer was used it would be necessary to remove with a product made for such purpose. You could try OOPS waterbased remover or a sealer stripper.
