Question: my wall is 9 feet x 15 feet. how many rolls do I need?
Document: I was unable to find any when I was purchasing this wallpaper so I felt like I was taking a gamble on whether the colors of the paper were what I was looking for. The small picture attached to the product does not do it justice!!! I did 2 walls, both about 93 1/2&#34; tall and between 10 and 11 feet wide. It took 4 rolls of paper.
So many friends thought we actually had brick on our wall, the effect is truly amazing, love it! It looks real and has a soft touch, utterly amazed every time I look at this wall.
This was a great purchase. The pattern is great and the overlay is perfect. It was easy to put up (mind you this was the first time I used wallpaper.) I have received so many compliments regarding the quality of the image. This was used as an accent wall for a &#34;Man Cave&#34; bar (6x8).
Let me say this is my first attempt at wallpaper. I bought two rolls to cover two small walls on either side of my brick fireplace. Don't be like me, go into this prepared with a blade, a smoothing tool and some extra wallpaper glue. Clean the wall first and measure, measure, measure. I had help and  even though we messed up lots the first wall came out beautifully. The dimensions of the second wall were a little different and we has issues keeping the pattern but we got it.
The repeat is about 2 feet, so if you're doing a small area like I was (backsplash), there's a lot of waste, but it looks fantastic when it's up. Everyone that comes over has to go and feel it to believe it's not really textured.
The problem is the glue didn't smooth evenly on the edge and now I need extra glue to button it down. I hate the line and even though I was super careful it's there. The glue should hold the end better. Other than that though the wallpaper is nice,  I wouldn't say that its realistic but it brings a lot of life into the room.
It's not cheap and it's not the best thing out there either; however it is very forgiving if you make a mistake. Due to its pattern and print I would recommend that you order at least 5% more than you need but no more than 10% should be necessary. We also used additional wallpaper paste although this paper has some on the product we found the additional paste to be immensely helpful. The brick actually looks better than the first roll I ordered from another site and ended up returning.
This wallpaper was my secondary choice after receiving wallpaper through another website, I realized we would need more wallpaper but to my dismay my first choice was out of sock online for several weeks. I needed a quick solution so I jumped on Amazon to query brick wallpaper and selected this product after reading several customer reviews. Buying wallpaper online sight unseen can be extremely difficult but I have to confess how happy we all were with the finished product.
I really like this wallpaper. I had never hung wallpaper before and had a tough time figuring out just how much water needed. Directions say to soak it for no more than 15 seconds and let it &#34;book&#34; for 2 minutes. Since I am new at hanging paper I had a hard time handling it when pulling it out of the water. The paper just didn't want to work with me and I ended up getting small tears on the edges.
this is great looking paper and very easy to hang on the wall. The only problem I had was lining it up so the design pattern would match up. it took a bit of cutting but I figured it and it came out great!
