indoor cinder block vinyls
regular high performance.....3" DRY roller and a heat gun! (careful not to roast the roller!)
I would only use wrap vinyl if you want it printed and laminated. high performance of course!
I worked in the movies 20 years and we did all kinds of whacky surfaces.
Here's a great trick to use on straw mats, brick, lino. fake inlay, cinder block, "chairbacks" (canvas), burlap and even carpet.
first heat gun down the high perf. vinyl with a dry roller and heat gun 2. apply 2 coats of Benjamin moore or equiv. Matte "stays clear" (clear polyeurathane water based) remember to let it dry between coats...this will seal your stencil and textile from "bleeding". then apply your (preferably latex paint) flat. remove your vinyl stencil just after it is dry enough.....if you wait overnight you will regret it...very easy...you can even airbrush etc. and add a gloss coat.
practice the method first on a test sample.
