Seems to work
Went on easy and it covered the amount advertised with a roller. Easy install and hopefully it works. No streaks or stains from rolling on!

Concrete densifier
This was the product we needed to put an end to the white silica dust from our unfinished basement. Works great!

New shop Floor
Ordered the 4500 to go on my new shop floor. Ordered directly from GhostShield. Shipping was fast and great communication from order to receiving. I applied with low pressure sprayer. I waited 7 days to apply the 8510 sealer. Happy so far . I would recommend .
