Review: Good product. Suitable as backer board when framing, - Product us as advertised.
Review: Nicely packaged to protect corners - I've seen a number of bad reviews about this product, but mine just arrived quickly and in perfect condition, with nice plastic corner protectors that did their job. I think some of the reviewers are expecting more from this product than it's intended use. These are great 3/16" foam core mats, which were surprisingly hard to find--most sellers only offer 1/8" think for white and that is often not sturdy enough. Also, all of the white mats I ordered are 3/16" thick, which is what I wanted, so I don't know why the title of the product includes the word "Many" in it: "Excelsis Design, Pack of 15, Foam Boards (Acid-Free), 11x14 Inches (Many, 3/16 Inch Thick Mat, White . . " To the managers of the company, I suggest you delete this word in the description as it sounds like many but not all of the boards are 3/16". I almost didn't order because of this confusing wording, but I'm glad I did. Perhaps you meant, Fifteen 3/16" Thick Mats. But again, great product!

### ⭐⭐⭐⭐ I think it's a good value, but read on, I have a caution to share on use of adhesives
*by D***N on April 5, 2019*

[See middle bracketed paragraph for what has changed in this review] From the advertising in Amazon it may look like they only offer Black, but White is a choice in the process of placing the order. I use a 3M spray can of contact glue to apply to the board and then I quickly place the photo, there is no second chance with the 3M Contact 90 spray, but it's quick dry means a good adhesion and no bubbles or creases so long as you are quick and exacting. There's also no adhesive wetness coming thru the print and once down you are done. [REVISION: See new photo. The 3M Contact 90 (TM) spray adhesive behaved initially as expected, and I have used it on 20x30 boards where foam was sandwiched between two layers as is done here. The sandwich this product uses either had too porous of layers lining the sandwiched foam or two thin. The photo which transferred flat initially began to show serious and unacceptable bumps and unevenness (see photo). It's reasonable to assume the fumes from the solvent based 3M adhesive continued to exude solvent vapors that passed through the outer sandwich material into the foam which dissolved/displaced, expanded, warped. I am absolutely certain the solvent used in the adhesive combined with the makeup of the outer sandwich layers to have a bad outcome on the inner foam. I will try to find a non-solvent based fast drying adhesive. These are of no use to me unless I find such a product.] They do make presses where you can dry-mount and have more surety of placement (assuming you perfectly line of the three pieces and closing of the press doesn't cause them to shift). but those presses are quite expensive and the dry-mount adhesive sheets aren't cheap and may be problematic to store depending on your climate. I find this board and spray contact cement a great alternative, but again, no room for a re-do if you don't place it correctly. Practice on a scrap board without the real photo until you get the knack of being fast and accurate in your placement. I spray the whole board then I lay the picture on at one end and then basically lay it down progressively until it's all down.
