cracklingvoice Posted July 11, 2015 Share Posted July 11, 2015 I'm restarting my terrain collection, and am going for an urban environment. If you want, you can look up the terrain I'm going to be using at: www.bplaser.com. I'm going to be using their 28mm Sci-Fi Buildings; particularly buildings 01, 02, 03, 04, 05, and 06. I want to say that I could spray the exterior with an adhesive and coat the surface with quikrete, or something like it. I'm going for a concrete look, but I'm not totally sure how to execute that. Does anyone know a better way to get the look and texture of concrete? Any suggestions would be awesome. Link to comment Share on other sites More sharing options...
Space Truckin Posted July 11, 2015 Share Posted July 11, 2015 I've never heard of coating a surface with quikrete like that. I'd be concerned that if the MDF was not sealed there maybe some warping/ swelling. I would think the cement in the quikrete will soak up moisture like a sponge - if it's not sealed over time it may make its way into the MDF terrain. Have you thought about textured paints and dry brushing shades of gray? Link to comment Share on other sites More sharing options...
cracklingvoice Posted July 12, 2015 Author Share Posted July 12, 2015 I am generally rather cagey about using texture paints, and I do want to take the more challenging road on this project. I'm fairly sure that priming the MDF first would help seal it from the adhesive, especially with two or more coats. Link to comment Share on other sites More sharing options...
Pitted Sliced Slayer Posted July 12, 2015 Share Posted July 12, 2015 I've used a water based wood putty mixed instead with PVA glue on cardboard/foam board with out any warping and it gives it a suitable rendered cement look to it. Link to comment Share on other sites More sharing options...
hendrik Posted July 12, 2015 Share Posted July 12, 2015 how about sealing it with spray on varnish and then paint it? since it's mdf i would definetly recommend getting a sheet from the local hardware store and doing some experimenting on it before you try anything on the more expensive buildings.

Bung Posted July 13, 2015 Share Posted July 13, 2015 Vallejo got some texture stuff, maybe have a look at that. Link to comment Share on other sites More sharing options...
cracklingvoice Posted July 13, 2015 Author Share Posted July 13, 2015 I wonder if I can't prime the MDF first and lay a treatment over that. I would assume that two coats of primer would keep any treatment I lay on from damaging or altering the original terrain. I looked at the Vallejo textures for water and stone effects, I think I found some options worth looking into. Link to comment Share on other sites More sharing options...
JGeils81 Posted July 13, 2015 Share Posted July 13, 2015 Maybe try brushing on some plaster of paris, let it dry and then paint? could thin it down a bit, but it dries very quickly unless you get the extended kind. Link to comment Share on other sites More sharing options...
Daevyll Posted July 13, 2015 Share Posted July 13, 2015 Since you are modelling concrete in a 28mm scale, normal texture paint would be too coarse I'd say. Try using a very fine grade of wall chalk like the type used by decorators. A well-known brand here (available in DIY stores) would be Knauf Fix & Finish.

Peredyne Posted August 5, 2015 Share Posted August 5, 2015 Seal the wood first, then use light wood filler that has been thinned with water so you can brush it on. Let it dry and then sand it lightly to smooth out the surface. I've used this same technique on foamboard and had no warping. Link to comment Share on other sites More sharing options...
