Welcome to HTS! :wave:Planning on constructing a DIY, curved screen. Frame will be wood, substrate will be sintra or other foamcore board, with canvas adhered to that. Will be a 5x8' size. Any reason BW wouldn't be a good choice for a rolled on paint?
The only sample of Sintra I ever saw was not smooth like plexiglass, but had a bit of texture to it to hold paint.Ok, I just wasn't sure how well you could roll on the paint on a smooth surface. Would it in fact "lay down" well? I'm just really used to canvas and thought it would hide better.
OK.As for the curved, I just really want a curved screen.
Most places that sell Sintra describe it like this "Sintra is a lightweight yet rigid board of moderately expanded closed-cell polyvinyl chloride (PVC) extruded in a homogenous sheet with a low gloss matte finish.". While it IS a foam board, it is not a foam core covered in paper or plastic.Oh, I had no idea it had texture. If that's the case, I will likely forgo the canvas. Is it easily dented or damaged? Sorry, I have no experience with it....I thought it was foamcore
You shouldn't need to. It takes a bit of time for the paint to dry so you should have more than enough time to take care of any roller marks.When rolling on a paint such as the Black Widow on a smooth substrate such as sintra, is it advisable to add a flow aid of any sort to wet out and decrease roller marks?
The only such aid I have tried is the one made for latex house paints called Floetrol. While most people that use Black Widow™ haven't found they needed it, it would not hurt to use it. If folks had a problem with roller marks they normally just added a bit of distilled water to thin the mix. Very few people have had problems with roller marks when rolling BW™.When rolling on a paint such as the Black Widow on a smooth substrate such as sintra, is it advisable to add a flow aid of any sort to wet out and decrease roller marks?
