Dry Treat's Stain-proof has always had a very high reputation with many tile installers and tile and grout restoration professionals. It is very expensive and has very high VOC levels. We see if paying the high price and dealing with the high VOC levels justifies using this grout sealer product.
Drytreat Stain-Proof has been touted for years as having an advanced sealant technology that was not available in other sealers. It states that the sealer will form a permanent bond to the stone or grout that never need to be reapplied.
It does have extremely high VOC levels and it is recommended that you wear a respirator when applying this sealer particularly in closed environments.

It is manufactured in Australia and is the highest VOC level sealant in our testing. It is also the most expensive typically running $80-100 depending one where it is bought. The local tile store sells it for $100 as can be seen written on the container. It is sold in specialized tile and stone stores and can only be sold in quarts due to laws covering high VOC products.
In our testing the Drytreat Stainproof did not perform any better or any worse then the other mid range sealers. There was still obvious staining from the mustard and a slight stain from the dirty motor oil. The high price tag combined with high VOC levels do not seem to justify using this sealer.
