This is the third time I’ve purchased this item. The first was to do a bathroom shower enclosure in our older home, to get it ready to put on the market. The results: outstanding! It made a 30 year old tile job look absolutely brand new! We recently moved to a brand new home and saw how quickly the grout starts to get “dirty” on a new grout bathroom floor (that wasn’t sealed), so I purchased the second batch to seal the grout from new: perfection! So then I bought it a third time to do our Master Bedroom floor…totally awesome! I would highly recommend this great product.
