Hi Shapeways,

I've come across a couple of posts that go into some detail with regards to sanding, filling, spraying, polishing...and so on, but I have a bit of a simpler question.

I'm very happy with the current look and feel of full colour sandstone, as it seems to well suit the models that I am creating. I'm just wondering if there's a simple (single) spray that I can apply that would (possibly) enhance the colours but mainly help with durability and handling issues. I'm already looking towards direct sales but think it advisable that I try and add some form of protection before passing on to any customers.

Many thanks,

Trilobite

I am waiting for my first model and will be trying this on it:

http://www.krylon.com/products/crystal-clear-acrylic/

Krylon spray gloss. It says it protects against moisture... In theory it should protect it and make it glossy.

Saw this one too, which may not be gloss, but still protect.

Again I have yet to test these out!

He tried Krylon and it ended up looking fuzzy. Rust-oleum Lacquer it is then!

I used Rust-Oleum Lacquer Spray Paint and it came out great: http://leonnicholls.com/protecting-sandstone/
The one thing I learned is to spray very lightly and build up layers.

I've tried several sprays, and particularly ones that are very water resistant if not water proof.

Krylon Clear Polyurethane (satin) on both sandstone and WSF. It will yellow some lighter colors and the yellowing is very noticeable on WSF.

Krylon Short Cuts KSCS079 Clear Gloss on WSF. Only a very slight yellowing was noticeable.

Testors spray lacquer on WSF. http://www.testors.com/products/137178 This is the clearest finish I found for WSF. No yellowing that I could detect.

They should all work on colored sandstone if you spray several light coats.
