Overall: these DuraGrid tiles assemble and disassemble easily, can be cut, lie flat, look good, and seem durable. They have male pegs on two sides that snap down into female loops on the adjacent tiles.

Once laid down the floor is OK to walk on even barefoot, and takes reasonable usage of patio furniture etc with no damage. If a heavy, hard object eg. a pot of flowers is dropped onto it, expect some permanent indentation but it won't break the tiles.

These are sold only in lots of 24 and 40 tiles, and shipped in squares of four. So you will get 6 or 10 such squares.

To know:

"¢ Plan the work so that each new tile going down will be attaching via its male pegs, into loops on the previous tile. Trying to get a side of female loops under an existing tile's male edge is more difficult and risks damage (see below). The shipping box has a diagram showing this idea but not discussing why.

"¢ To separate tiles, bend their joint up to see which edge is male (pegs) and which is female (loops). Starting at one end of the joint, rip the male pegs up and out. This will take some force but is unlikely to cause any damage.

"¢ For installing more than about a dozen tiles you WILL need a light rubber mallet or a regular hammer with cloth wrapped around the head. Don't rely on your heel or palms (see below on edging). And you WILL need good gloves; the bottoms of the tiles are sharp.

"¢ The tiles and edging can easily be cut with a hacksaw, though you will unavoidably have a raw edge. Trimming excess plastic or removing unwanted loops is simple with diagonal cutting pliers.

"¢ This is soft plastic and the peg / loop mechanism is a tight fit. If those aren't well-aligned before you force them together, the male peg CAN GET DEFORMED. So go slow and easy on each joint - MOST ESPECIALLY when you must attach a female edge to a male edge already laid down. The safest thing there is to lift the male edge, slide the loops under and ensure that they encircle the pegs before using any force to press them together. This is the only real difficulty I had.

"¢ If a male peg gets deformed, you can use diagonal cutting pliers to trim away the damaged plastic and recover the tile. Of course that one point won't snap in as it should, but others around will probably be enough.

"¢ DuraGrid tiles are made by SnapLock Industries in Utah. They also make very similar tiles but in different materials and colors as RaceDeck flooring. Compatibility between DuraGrid and RaceDeck tiles is nowhere described. SnapFloors, which is either a competing company or more likely a sub-brand of SnapLock, does offer RaceDeck compatible parts.

"¢ You will probably want edging pieces for the completed floor. The only ones found on Amazon are from SnapFloors for the SnapLock RaceDeck tiles, with unstated compatibility to these SnapLock DuraGrid tiles. Go figure. And they are only available in black.

"¢ SnapLock does offer gray male and female DuraGrid edging direct from their factory. These can be bought at half that price from the WayFair on-line store. Unfortunately, unlike the RaceDeck product, they do not have special pieces for corners. So you will have to cut this edging to length in some cases, and when done clip off any remaining visible loops. The edging is a softer plastic than the tiles with a slightly different color. Not bad and maybe the slight additional flexibility helps with transitions, but not perfect.

"¢ Installing edging is best done by hand, using the mallet only for completion. The trickiest is attaching female edging to the male side of a tile. And indicated above, lift the tile as much as possible and, at an angle, slide the loops under to make sure the male pegs are properly started. Then snap the edging on by hand and lower the tile with edging back to the floor. Never just slide the loops under the male edge and start hammering - that will soon wreck a male peg and you'll have to disassemble the floor to replace or salvage the whole tile.

Four stars instead of five only because SnapLock does a poor job of providing edging. It should be on Amazon along with the tiles, and compatibility made clear.

Came on time as described. I bought another and will soon buy three more.

It went together easily. Used a jigsaw to cut the edges. I also used deck screws to hold in pieces that were small on the angles of my deck.

Very nice. Strong.

These tiles look great and installing them is as simple as lining up the connectors and stepping on them to snap them together. I did two boxes in probably 30 minutes (and that including moving deck furniture on and off of the area where I was working. Still have to order another box or two to finish up, but these are excellent. They are probably 1/2 inch thick and the color is solid all the way through (I was able to see this as I had to cut some to align on my deck) so I'd expect them to hold up to weather well and I wouldn't expect the color to fade. My only small issue is they came already snapped together in a 2'x2' square (easier to ship maybe?), but I needed a 1' row so I had to take them apart. Took me a few minutes to figure out, but all you have to so is simply bend them towards each other along the seam and they'll snap apart pretty easily. An excellent solution to no longer having to paint my deck every spring!

I'll post pictures of my deck when I finish
