The 511 impregnator was one of the big surprising disappointments in our testing. When the testing was initialized and the contaminates were placed on the grout samples it became immediately apparent that this was an inferior product due to the lack of beading by the motor oil and the acidic soy sauce. Only the Tile Guard Silicone grout sealer had a worse initial bead up as the 511 Impregnator.
As you can see there was prominent stains from all the contaminates. Also the dirty motor oil left an darker spot then some of the other sealant products. What is especially bad with this sealer is how the contaminates bled out and soaked into the grout creating bigger stains then the original samples. For such a high priced high VOC level sealer this is an extremely bad sealer.
