theodoropoulos Posted March 6, 2014 Report Share Posted March 6, 2014 I always work with high gloss finishes with the same process.....spray/wet sand/buff and comes to high gloss... Once i sprayed with matt and followed the same proccess and it turned out to HIGH GLOSS! and that is unwanted.... Forgive me but i have never tried it before...so how i manage matt or satin after wet sanding?? i suppose i buff until the point i want...but is it the correct way?? please give me your lights!

killemall8 Posted March 6, 2014 Report Share Posted March 6, 2014 As far as i know, flat and satin finishes arnt supposed to be buffed. Any flat or satin finish can turn to gloss when buffed. Just like how satin black guitars end up having a really shiny spot on the arm rest. Quote Link to comment Share on other sites More sharing options...
RobSm Posted March 6, 2014 Report Share Posted March 6, 2014 Hi. If you wet sand finer than 600 you pretty much have a matt finish. What I do for non gloss finish is wet sand to 600 and then rub with 0000 steel wool and wax. it turns out OK. Try it and see if you like it. You can always shine it more or rough it back a bit.

theodoropoulos Posted March 6, 2014 Author Report Share Posted March 6, 2014 Thank you for response... There is a local luthier here who says that he sprays only and not wet sand and buff... So the satin or matte is achieved only with his spraying skills! is that possible???????? in every project i do there are tones of overspray and orange peel!! am i so unskilled???? haaaa GOD!!!! i think the steelwool and wax are the best !!! thanks !!

westhemann Posted March 6, 2014 Report Share Posted March 6, 2014 People misunderstand matte finishes.A true matte finish has a flattening agent in it that diffuses light...like silica.It will not "buff to gloss".Just because you make the surface shiny by polishing and waxing,that doesn't change the diffused clarity of the matte finish. If you can't tell that it is matte,then you probably either have a very low matte finish or it isn't thick enough to diffuse as much as you want. All finishes start as gloss.Flattening agents are added. Buy "Understanding Wood Finishing" by Bob Flexner and read page 132...If more people owned(and bothered reading) this book there would be a lot less misinformation going around.The book even has illustrations. Of course you can leave a bunch of tiny surface scratches to simulate a flat finish,but your skin contact will eventually gloss it up. In other words,there are two ways to achieve the look...

westhemann Posted March 6, 2014 Report Share Posted March 6, 2014 By the way,the wax fills the sanding scratches and will make it appear glossy if it is not an actual flat finish... Quote Link to comment Share on other sites More sharing options...
theodoropoulos Posted March 6, 2014 Author Report Share Posted March 6, 2014 For those who cannot buy this book...i did not understand...what are those two ways?? Quote Link to comment Share on other sites More sharing options...
Prostheta Posted March 6, 2014 Report Share Posted March 6, 2014 One way is to use a "normal" paint and only wet sand it up to a grit like 800-1200 or whatever. The fine scratches make it look matte, however it will end up going glossy with use or if you wax it, as Wes says. The specific "matte" paints have an additive which stops it from looking glossy by redirecting light in random directions. That is the "flattening" agent. To address your specific techniques used, if you wax and buff a matte paint it removes the deliberately imperfect surface that the additives put in there to create the matte look.
