In short yes. The ingredients in the 3C Smooth Finish 2-part formula are such that the cured epoxy resin will adhere to multiple surfaces including most types of stone, all timber based substrates and also some metals. As with all products that require a bond to single, double or even triple sides, a small amount in a test area is strongly advised to check the outcome but in general after in-house vigorous in-house testing, we're confident that it'll stick to and fix most general construction materials both old and new.

With Smooth Finish being targeted mainly (but not exclusively) for use with timber, the obvious colouration is a beige but please note;  the 2-parts of the filler are extruded from 2 x separate chambers in the single cartridge thus you'll see 2 x different colours of material come out when gunned. To assist you with the mix and subsequent application, the 2 x parts of Wood Repair extrude as: Part A= Greeny-Beige / Part B= Mid-Grey. When mixed properly, the final wet resin mix will be a distinctly darker Brown-Beige colour. When the application is fully dry (after approximately 1 hour) this, in turn finishes to a slightly darker browner beige colour still.  To get a visual idea of these colours, please see the pictures above.

By combining the 2 components of 3C Smooth Finish 2-in-1 into a single mastic sealant style cartridge design, we've designed a product that's accessible for all types of users, from home user, DIY enthusiasts right up to structural engineers, this means that to extrude the material, a single, standard skeleton gun can be used. Please note, the plunger that pushes the material out from the bottom coupled with the actual (double) material itself, is fairly tough to extrude so a decent quality gun is advised (rather than a cheap DIY style gun).
