The 2nd coat is a full coat. after applying this coat... step back... and see if there are any 'soft' spots. lightly 'feather spray' the soft spots. let coat dry for 45min to 1 hour.
The 3rd coat is also a full coat. after applying coat... again, step back, and see if there are any soft spots... and 'feather spray' only those.
Let dry for a least 1/2 a day before viewing. it'll take a week or more for the screen to cure and show it's full potential.
ROLLING INSTRUCTIONS
Use a 9 inch roller, 3/16" nap - white smooth synthetic roller.
(or a 6 inch foam finish roller with rounded ends)
DO NOT USE ADDITIONAL EXTENDERS Extenders such as floetrol are not needed with this mix. the water-based urethane is already a natural extender and does not require any additional help.
DO NOT DRY ROLL dry rolling will leave/introduce roller mark tracks that will not go away.
DO NOT OVERLOAD YOUR ROLLER. Working in 18-20in. vertical bands, use vertical up and down strokes never ending a stroke on the screen itself. work fairly quickly from left to right,
Feathering and overlapping each vertical band by 8-10 inches and getting good even coverage. do not work the paint for long. the mix needs to go on wet and rather glossy looking... which allows the wetness of the mix, gravity, and time to blend the components together giving the screen a better opportunity to dry with fewer to no roller marks.
When you are done with each coat... the screen surface should look like a wet light grey glass sheet... and it should take about 15-20 minutes before you see any signs of drying. otherwise, the coat is likely being applied too dry.
When rolled properly, the screen will dry to a smooth flat/eggshell finish.
SCREEN SUBSTRATE CHOICES
Recomended screens & substrates
Light fusion - a first surface mirror, a second surface acrylic mirror, a reflective smooth metal substrate, a brushed/polished/machined/ or an anodized metallic substrate.
Light fusion II - white translucent acrylic #2447 substrate
Durotherm rigid pvc white panels, Sintra/Komatex rigid expanded foam pvc panels, or polywall sheets.
Semi-gloss white melamie surfaces such as doable/clones and melamie treated MDF boards are preferred over rolling a gloss white basecoat.
The most available DIY option is to use a semi-gloss (or satin) ultra pure white basecoat, or basecoat available from XFS.
When using a ultra pure white basecoat spraying the basecoat is prefered.
For a smoother ultra pure white basecoat (non XFS)... a 1:.5:.5 mix of (upw/Minwax polycrylic/water) is recommended.
