Hi all,
I would like to know what I should use to glue a smooth plastic backdrop to wood. I have a tube of liquid nails on hand, can I use that? What about wood glue? Should I rough up the plastic with a sanding block first? Thanks in advance for any help.
The liquid nails will work, but it’ll work better if you could ruff up the backside of that plastic with some sandpaper to give the LN some bite to grab onto.
Wood glue or white glue won’t work very well. Your best bet would be the liquid nails or silicone.
Thanks very much for the quick response. I guess I’ll be using the liquid nails.
Just spread it kind of thin with a putty knife so your sky isn’t lumpy.
Great advice. I didn’t think about that.
For large area bonding I would use Wall Bond. It is basically liquid nail in a gallon can. It is made by the same manufacturer and is in a gold labeled can. This is used to secure laninate or FRP panels to plaster, DW or wood. To use just spread with a notched trowel and set the backdrop. This continuos full bond will be more secure and reduce any bubble or buckling during expansion on contraction between the different mediums. The notched trowel will allow an even application of adhesive and give a good initial tack but still allows any adjustment if necessary.
I’ve done similar but used vinyl floor adhesive. You can get a quart pretty cheap. I’d use a very small notched trowel.
Be careful! Liquid Nails makes many different products - they all look the same but have different uses. Most of them contain petroleum distillates that will attack/disolve plastics. If the label says “OK for styrofoam” etc it’s OK for plastics - probably the best for plastic/wood/metal joining, but it is a thick material that in not good for such things as HO grab irons! Read the label and use it accordingly.
Thanks for the info guys. I tested the liquid nails on a scrap piece of wood and plastic and it worked pretty well. I had a hard time finding the LN I wanted at Lowe’s. There are about 6 different products that are used for wood or mirrors, but I finally found the liquid nails “for projects” that I’ve been using to glue foam boards together with success. Thanks again.
