Title: Securing plaster casted walls?
Post by: Caleb Abbott on June 13, 2020, 19:54
Hi, silly question time again.

I've cast in plaster some stone walling and am needing a way to secure them to the baseboard, which is covered in Cork!

When I tried with scola clear pva it was too thin and the plaster/cork just soaked it up.

Any ideas on how to secure the stone walls to the baseboard?

Thank you in advance

Caleb Abbott

You could use .white silicone caulking. You may need to prop up the wall till the caulking has set usually not long. I Will try to attach a pic with my experience using this. No More Nails also does an excellent job but costs more.

In the past I've used wood glue with no problems, and still use it today. You could also use Hot - melt glue. I use holt - melt glue directly on my Styrofoam board to hold my track in place. This I apply lightly and in small sections. Once dry it will not come off.

UHU or UHU Por (foam compatible) might be another possibility. With both surfaces being porous, gluing it "wet" should be possible. (I often struggle with contact adhesives on non-porous surfaces where you need to let the glue "go off" first and you only get one chance at positioning ).

I've used both silicone and UHU before now. The PVA needs to be of the thicker variety for this purpose, the thin stuff as you say just soaks in!

One possibility might be to "size" or seal the plaster before gluing as one would a newly plastered wall using thinned paint or even thinned PVA?
