"Rolls of static grass & glue" Topic

I'm going to glue a 4'x4' paper backed grass mat onto a sheet of MDF. Will PVA glue work ok, or has anyone had problems with this method?

Try to use tacs in each corner to keep it tight as it can warp and go wavy. Staples would work too.
Then a little work to hide the nails/tacs/staples and bob is your uncle..

It tends to wrinkle when the glue dries. If doing this again (or rather when I do it) I will simply pin it down or use odd spots of glue to hold it taut rather than let the whole sheet become soaked with glue.In fact double sided tape along the edges and a few bits in the middle might work too.

Have you considered liquid nails? Squirt from tube spread out as evenly as you can and adhere the mat with pressure. Tacking the corners would be good too.

for paper scenery, I've use double sided permanent scrapbook glue (comes in an applicator roll like tape) for cardstock ground tiles on foamcore and avoided warping issues I've experienced with glue.

If its paper, try using wallpaper glue and the brush/ rollers associated with same. Don't forget to paint and then use sizing on the board prior to add the paper.

Just to add another suggestion: adhesive spray.

You have to be careful when you lay it down, but it won't warp and it won't get creases if you keep it taut when you lay it down.

Whatever you use, I would suggest using a larger piece of mat than the tile and when it is dry, cutting around the edge with a razor. This will give you some wiggle room when applying.

My experience with laying down large sheets of grassmat is to work slowly from one end to the other. Paste glu onto paper. Paper will stretch when wet and you may get wrinkles as part of the mat is wet and the rest is still dry. But if you lay it down in 6-12" increments and keep it taught it will miraculously dry flat (and any small wrinkles will vanish). This is because the paper seems to shrink again when the dry.

No expert but have done this a few times now and this was what I have learned. The first time I did this I painted the glue on the wood and it was a disaster wrt unwanted wrinkles and folds.

I would try 3M Photomount or Display mount whichever is the stronger (I can't remember off hand). They are designed for this type of application although between card/paper surfaces so they might work on MDF. I also understand the carpet industry has a powerful spray adhesive.

Wear a mask though as these things are nasty.

I do this all the time!, i actually use wallpaper paste.

Oh, I should say I tend to use 18mm thick Mdf and use one side as "green" and the other as snowy! But it also works on a base of polystyrene and plaster filler.

And BTW, wallpper pste is by far the cheapest stuff you can use.

I use wood glue for glueing the polystyrene to the hardbord backing sheet.
