Rough surfaces, small rooms, and any claim its record doesn't carry.
The 3/8" microfiber-class nap has no business on masonry, stucco, or rough-sawn wood — it bridges the texture and shreds on the abrasion; those are polyester long-nap jobs.
An 18" cover has no business in a normal cut-up room; that's a 9".
And because the accepted claim set is empty, this page won't sell the cover on specific capacity figures or a stated epoxy/chemistry rating — for a documented industrial or floor cover, the woven 18" (91808) is the honest pick.
This cover's strength is a clear, narrow one: wide, smooth, fine-finish interior work.
Light hand — microfiber-class covers punish pressure
A fine dense pile carries and releases a lot of paint; press it and you flood the wall and spatter. Load off an 18" grid to no-drip, distribute off the wet edge, and lay off each section in light single-direction passes to align the stipple — the move that delivers the flat, lap-mark-free look this cover is for. De-lint the new cover before the first pass. Cleanup takes patience: a dense fine pile holds paint at the fiber base and rinses slowly — work warm water through it until it runs genuinely clear, because trapped paint dries into a core that coarsens the next finish. System: 18" frame, bucket-grid, pole — the production kit an 18" cover assumes.
Asked at the counter
BUYER QUESTIONS ANSWERED BEFORE THE CART, NOT AFTER THE RETURN
Is it microfiber?
The E-volution series is positioned as microfiber in the line doc's fabric semantics; this specific SKU carries no accepted claim beyond its store title, so the microfiber character is class knowledge, stated as such .
What's it best for?
Big, smooth interior walls and ceilings where you want a flat, lap-mark-free finish — the 3/8" smooth-wall nap at production width. Fewer passes, finer result.
91817 or 91818?
Smooth walls → this 3/8"; light texture (orange peel, knockdown) → the 1/2" 91818. The nap decides — feel the wall.
Why 18"?
To flatten the pass count on big open surfaces; it needs an 18" frame and a bucket-grid. Wrong tool for a cut-up room.
Rough walls or masonry?
No — 3/8" microfiber-class bridges texture and tears on abrasive masonry. Go long-nap polyester for rough surfaces.
How is it different from the Hyde 47350?
They're the cross-house twins — same 18" microfiber 3/8" finish cover, one Richard, one Hyde, sharing a catalog because Hyde acquired A. Richard in 2003.
