So I am going to glue stone to balsa wood. I'm wondering if the best way to do it is to (A) paint the wood first, so the surface is less porous, and use E330 or something, or (B) not paint the wood, and use a glue intended for porous surfaces?
Any thoughts on the matter? Other parts of the wood, other than the glued surface, will be painted, so it isn't much extra effort to paint the whole thing.
The tiny slabs to be glued won't be very heavy, and the thing is decorative only, so the glue doens't have to withstand much.
I'll share what it is later, probably do a WIP thread. But for now it's a big fat secret.
So, to paint or not to paint?
Thanks all!

Epoxy.a small amount and it will dry quickly.just make sure the stone is where you want it.the epoxy won't give it back:-)

My first thought was "if you paint it after gluing on the stone, you might get stain/paint on the stones"... and that would be no fun at all. If you have more projects to use epoxy on, I'd recommend what I use. www.westsystem.com/ss/g-flex-epoxy But it's pricey if you only need enough for one project.  Good stuff though for gluing rocks and it has a longer pot life. |

sound like you should paint first
then sand the area your epoxying
reason stated by aim~ee
plus the paint may not allow a secure affixing
not likely-- but maybe
and so forth

To clarify, the painting will take place before the stones are glued. But the question is whether to paint the whole thing, or just the areas that will be showing after the rocks are attached.

are you going to paint the whole stick before you glue the stones?
will this stone be glued to the painted surface ?
or will it be glued to the end of the stick like a dopped rock ?
Or on the side like a tomahawk?

Hi Ed. Think of it maybe like a small cutting board, with the flat surface covered with a very thin slab, and the ends painted with purty designs. The question is whether to paint the flat part of the cuttingboard which will end up under the slab, or just glue the slab to the wood without any painting. In any case, I would paint the ends first so as not to end up painting the stones, as Aimee mentions.
I'm just wondering which would work better: (a) Glue meant for wood/porosity, with no paint, or (b) glue meant for no porosity, with paint.

I would use a paint that your epoxy will stick to and epoxy the rocks to the painted surface. I would allow the paint to fully dry and cure for several days before attaching rocks, the paint will gas off while curing and the gasses could interfere with the bond.

then I say glue the stones to the unpainted wood but then will the slabs be like a mosaic? if so... what about the seams? wouldn't want the unpainted wood to show thru hhhmmm... I'll trust your judgment in this Susan g'day E  |

I think I'm going to try it unpainted first, with gorilla glue, contact cement, PL Polyeurethane Premium Construction Adhesive, or silicone caulking, not necessarily in that order. Nope Ed, no seams. |

Susan
I would just use Elmer's white wood glue to unpainted wood, assuming that it is a flat slabbette to the wood and you have lots of contact area. I have glued heavy rocks that had a saw cut through them to the end of a 2 by 4 using white glue. Then clamped the wood in the saw and stabbed away, never had a rock come off. NOTE. I clamped rock to wood. Cheap way to go as well, I bought some 15 minute to dry white glue and was slabing in 30 minutes it really did dry fast. The secret to white carpenters glue is to clamp it

sounds like a plan!
a freshman high school project
I made an jig saw mosaic picture out of wood
a 16th century rider on a horse
there must have been over 200 pieces
of different types of woods used to depict the scene
the pieces were cut out on a band saw
and my seams were less than perfect
I caulked the whole scene to fill in the seems
then went back and painted some of the worse parts
I used Elmers glue
not single wood puzzle piece as come off
and its about 45 years old
g'luck on the project !
we'll look forward

Huh, yeah, I guess it IS the same issue as gluing rough to blocks for sawing. And I already have Elmers, so there you go.

Cyanoacrilate (AKA superglue) is great stuff for glueing Balsa. My son flies model planes and when they have a hard landing and bits of Balsa get broken a drop of cyanoacrylate and the broken bit sets harder than the original. Quick too, minor repairs and he can be flying again in no time.
For glueing stones I generally reckon two part epoxy is best, but in the last week I was introduced to a glue called "6000" by a Dichroic glass person, it seems to stick very well.
