The Legacy LP Premium sub-floor is awesome. I have used it in the past and loved it and this time was no different. I used it over some questionable older subfloor for a temporary storage area while I finish the rest of the house, will permanently attach it later on and use it more in the rest of the house. Huge difference, not afraid to walk anywhere on this stuff, its strong and very supportive. About half the cost of the other AdvTch stuff and just as good or better in my opinion, why not get this instead!

Delaminating after raining twice. Floor has only been down two weeks
I saw good reviews on this product , but after two rains the floor is delaminating. I wish I would have spend the extra money on aventech.

    No that great
    A few things to know before you purchase this product. 1) It is only 4 feet wide which includes the 1/2" tongue and groove. So every row you install, you lose 1/2" inch in width. If you have a room 12 foot wide, you will be short 1.5" inches. 20 foot wide, 2.5" will need to be filled in. Maybe this is how all sub floor panels are? 2) The reference marks for nailing are not accurate. On some boards they are close, like on the edge of the joist. Other boards I found to be 2 plus inches off!!! They cannot be trusted so you need to measure and mark you joist locations. 3) The worst thing of all, the panels are not square. If you give an even 1/8" gap along the edges, between 2 panels, like instructed, then you tongue and groove joint on the next row will not give you a straight line. When you install the next row you will find a "high" spot where the 2 corners of the first row panel meet. The tongue and groove joint will be tight at this "high" spot but will open up to almost a 1/4" at each end of the 8 foot board. If you make the tongue and groove joint perfectly straight, then you will have an edge joint that starts tight at the front corner and opens up to 1/4" by the back corner, 4 feet away. Very sad. The panels are solid and do seem to hold up to moisture. So it's not all bad but quality control on these things is lacking. I had to tear up 2 boards and replace them when I found that they were not square. Wasted half a day and money in replacing the boards.

      Wrong Measurements
      Measurements are not accurate. Length 95 9/8” And Width was 47 3/4” outside to outside. Now the width might not seem like a big deal but 3 of these grooved for a floor is 142 1/2” which is an 1.5 inches short when you bought 12 feet.

        I’m just a DIYer. I’ve used this product for years. Love it! I built a “temporary” ramp to get into my shop a little over 3 years ago. It’s been exposed to the elements and is still holding strong.

        Easy to cut, boards stayed flat and are study even before they were installed. The tongue and groove fit together with easy and came together tight. Very happy with how study if was after it was laid on the floor joists and fastened down. One piece of advice, wear work gloves when handling this product. It is pressed together small pieces of wood and has a tendency to leave small splinters, in your hands and finger tips if you don’t ! I would recommend this product due to is sturdiness and price compared to plywood.

        I will update after how I am treated. I build alot of homes and no issues till this one. 100 sheets installed. Within 2 weeks all turn brownish black. Than all edges curled bad. They had rep call me and say it’s normal. Than said my have to sand seams even though that’s not there warranty. Basically giving me the run around. Rep basically could careless. It’s sad cause it’s so obvious. And 2 weeks going bad and delaminating. Least rep said it’s normal and told me sand seams
