Array! PACAR2420 Self-Adhesive Dry Erase Roll, White, 24" x 20', 1 Roll

Keep in mind -- you get what you pay for.20 bucks for 40 sq ft of dry erase surface -- or go and spend 200-300 bucks on a hard-surface equivalent.I bought this, even after reading the other reviews claiming that it sticks to nothing, falls easily, etc...and if you're trying to place it on a schools cinderblock wall, then I completely understand why it is falling, because those surfaces are very porous (lots of little holes in the cinderblock, allowing air to get beneath the surface).If you're trying to hang it up in your classroom, and you have these types of walls, use it to build your own actual whiteboard, by getting a sheet of light-weight wood or something...place this onto that wood, and then hang the home-made whiteboard up.With that in mind, most of the other reviews are correct...this does have a bit of trouble sticking once it is up (I have multiple bubbles in it, from just having it up over night.)...however the bublbes don't actually interfere with writing. They're just there...and is acceptable for a $20 writing surface.As for the falling issue? One nail or thumbtack in each corner solves that.I'm giving it 5 stars, for the value.20 bucks, and you get a useful writing surface that does exactly what is intended, and you get a large amount of it. However, I wouldn't recommend it if you're after the quality of a $200-300 whiteboard.

Very cheap yet durable and practical product worth buying if you don't need a permanent solid whiteboard. Make sure you prepare your surface with great care and it will work perfectly.If you are attaching to a standard, painted wall, carry out the following steps:1) Lay down a dust collection mat below the area you wish to apply the whiteboard paper.2) Sand entire surface you intend to apply the whiteboard paper to with fine sand paper. Take extra time on any rough or protruding areas/edges and use a variety of strokes (ie side to side, up and down, spirals).3) Take a damp towel and thoroughly wipe down the entire area you just sanded. Leave area to dry for at least 2 hours.4) With someone to help you, peal off 4 inch sections of the back at a time and attach to the wall. Begin by marking the corners with light pencil and ensuring your markings are parallel to the floor. Attach the first 4 inches only after having your partner hold up the end of the paper (with backing still attached) along the parallel line to the floor which you just marked. Apply the first 4 inches.5) With the help of your partner, continue in 4 inch segments, wiping and compressing the paper down with a towel in strokes directed from where the whiteboard paper has already been stuck toward the unseparated paper.6) If you are planning on overlapping any segments, start by attaching the bottom most first then working up while leaving at least 2 inches of overlap.7) If you have a white wall, consider drawing a boarder onto the paper with a black Sharpe so as to not unknowingly continue writing onto you wall.Paper will need eraser liquid remover after some time but still looks clean with age.

This is a pretty good product. I've used it on the walls in my home office and it doesn't leave any residue and the white is perfect. I have been a home teacher for years. I sometimes use old-fashioned chalk and chalkboards but then I start using whiteboards. I see my allergies have come down a lot, I was brought up on chalk broad and they were always fun to write on but the white broad is better for my health.

I used this roll to convert an old chalkboard into a dry erase board. I knew I was going to use the board to display the schedule for the week for my six different classes, so I cut the roll into six different sheets and covered the gaps with ribbon (see customer images) - worked great! The kids couldn't tell that it wasn't one full sheet unless someone moved the dividers.Some of the advice in the previous comments was very helpful. One, do not try to do this by yourself; you need at least two people to effectively hang the paper and remove the bubbles. Two, do be careful when cutting because it can tear a bit if you are careless.The only reason I gave four stars is that in humid weather they bubble up a bit and need to be smoothed out about once a day. During the cooler months though not a single problem.If you're looking to convert a chalkboard into a dry erase board, I highly recommend this product!

We used this in our office to create a large dry erase area. The best part about the product is that expo markers do erase well - especially when using dry erase board cleaning spray. The negative is that the adhesive on the back is not as strong as I would prefer for a permanent solution. We used white duct tape around the border to secure it and then framed it with dark color wood trim purchased from the local hardware store. Great product for the price - especially if you would like to remove the product easily from the wall.

Super bueno. Lo usé en una ventana y quedó súper bien. Se borra fácil y se instala fácil.

I stuck mine to some 3 or 4mm mdf type panel I got from home depot, that is white on one side. I cut it down to 2' x 3' and routed the corners with 1/2" radius and then stuck this stuff onto the white side of the panels.It will be durable enough I think. It went on easily and I trimmed the rounded corners with a sharp utility knife.I will be using them for students to write on.Standard dry erase markers work well on the surface and erase easily.I would get it again.

Es un muy practico. Sin embargo no pega muy bien en la pared por tanto tendrás que usar cinta para que se mantenga en tu pared

No pega bien en el muro, a los días de que lo pusimos se cayó!

I created my own custom whiteboard by taping this stuff on squares of foam board and attaching to walls. Works awesome. Erases well and the tip I read about using a magic eraser for erasing older writing works beautifully as well. I looked at a lot of other options for making a cheap whiteboard, this is the cheapest method. For about $50 of materials and 4 hours of time, I created a custom whiteboard (3 feet long and 7 feet high) that would have cost me 10 times as much had I bought an "off the shelf" whiteboard.
