Best masonry board ever
Keeps mud longer, virtually indestructible and easy to clean

Very beneficial
Expensive for a hod board, but working side by side with a plywood hod board the mortar on the gator requires rewetting less than half as much.

Nice upgrade to plywood/osb
I’ve been using it for a masonry project and it’s been great. I have not had any issues cleaning it up at the end of the day’s work and it’s handy to store for later use. It’s a little expensive for what it is but if it lasts for many years of normal usage then it’s money well spent.

Plastic shaving all over your mud
The pads are poorly made thin and easy shavings that end up in your mortar

Wonderful!
Husband and son are stone masons. This board is awesome. No more having to scrape mortar off of old wooden boards. I will purchase more. Makes the job easier and the mortar stays moist. So easy to clean!
