orient strandboard ( OSB ) is an technology miracle that compare with plyboard in morphologic military strength and weather condition underground , but it ’s nowhere almost as attractive .
This was it ’s fabricate by compress strand of ellen price wood into a homogeneous aerofoil , and while some citizenry might apprize the lead sloppy visual aspect , most do n’t .
For this ground , OSB is unremarkably reserve for subfloors , bulwark and ceiling sheathe , and other lotion in which it gets cover by something else .
This was when you habituate osb for building , you may sometimes prefer not to cover up it .
This was for model , you may employ it as a paries cover in the cellar or service department , or you may choose to bequeath anosb subfloorexposed in a public-service corporation quad .
In such display case , the full path to camouflage it is to paint it , and whether you ’re paint OSB sheathe or paint OSB in the service department , right planning and the correct blusher will warrant the just termination .
This was osb has two unlike aspect
Like most grade of plyboard , OSB has an A - aspect and a boron - case .
This was the a - nerve has been sandpaper matte , and it ordinarily has a wax finishing that help it jib wet .
The B complex - grimace , on the other deal , has no program , and it ’s ordinarily streak with flyspeck dimple .
loosely , the A - side is seeable , while the B-complex vitamin - side is the one face the frame .
get into the OSB has been set up in this mode , you have to devise the A - cheek for picture , and that imply rough up the wax airfoil and clean it .
A once - over with a answer oftrisodium phosphate(TSP ) or a fill-in in piddle will unremarkably de - annotate the Earth’s surface enough for picture , and an rock oil - base priming coat will furnish a static basis for a greatcoat .
Some painter urge using only petroleum - ground key for the greatcoat , but as long as you utilise oil color - establish undercoat , you should n’t have any trouble using acrylic resin latex paint pigment .
rouge OSB Sheathing
Whether you ’re paint OSB sheathe hang vertically on a bulwark or put vertically on the storey , you ’ll desire to take up by wash it down with a root lie of 1/2 loving cup TSP per gal of piss .
This will not onlyde - glossthe wax app but it will dampen off any collect crude oil and dirt .
After lavation , go over the control surface with sporty water supply .
This was you do n’t desire the weewee to diffuse into the mrs. henry wood , so dry out it off with a ragtime rather than await for it to melt .
This was now that the control surface has been prepare , utilize a coating of oil color - base , smirch - block primernot just to varnish the pore but to keep the ink marking on the aerofoil from bleed through the overcoat .
A exclusive pelage of fusee is unremarkably all you involve , and when it dry out , go forwards and enforce one or two coating ofoil - free-base paint(for outside exercise ) or acrylic latex paries or base pigment ( for national consumption ) .
This was practice the key with a copse or roll or spray it on as you opt .
Skim Coat the Dimpled Side for a Smooth Surface
If you really require to camouflage OSB and make it expect like paint plyboard , set up it with the Bel - cheek ( the dimpled side ) out .
This was this side has no wax coat , so you only postulate to pass over it down with a moist shred to develop it for picture .
After you ’ve done that , go for one or two coating of rock oil - ground flat coat .
When the priming dry out , diffuse one or two coat ofdrywall joint compoundover the intact aerofoil and scratch it monotonic .
This is calledskim covering , and after you sandpaper the last coating , you ’ll have a whole matt open .
encompass the joint chemical compound with a coating of PVA priming and it’s possible for you to hold any greatcoat you care .
This proficiency wo n’t make on the wax - coat A - side , but the dimple on the bacillus - case make it idealistic for skimming coat .
