a third of the bristle deep; tap the excess inside the can, don't wipe it on the rim. Laying off: apply with pressure, level with almost none — long, light, unidirectional strokes so latex closes flat. Sizing: match the brush to the face; a flat wider than the face rides its corners onto surfaces you didn't mean to paint, and a flat too narrow doubles your strokes. Edging with a straight flat: load light, lead with one long edge of the brush, and go slow — you can hold a decent line on straight trim, but ease off where precision matters and let a sash brush take true cut lines. Cleaning (the multi-year part): water-based paint washes out in warm soapy water; flush up into the heel until it runs clear, spin or shake dry, comb straight, and hang or wrap so each flat dries in shape. Paint cured in the heel, or a brush stood on its tips, is what ends a brush early — comb and hang every session (the 45950 comb and 43470 spinner exist for this).
Asked at the counter
BUYER QUESTIONS ANSWERED BEFORE THE CART, NOT AFTER THE RETURN
Does this set have an angular/sash brush?
No — all four are straight flats. For cut-in lines add a sash brush or choose the 81303.
Is it for latex or oil?
Latex and water-based finishes — polyester keeps its shape in water. For oil, use the natural-bristle 81302.
What's the biggest brush?
A 3" flat — the field brush that the three-piece sets don't include.
Standard polyester vs SRT — does it matter?
On ordinary latex, barely; on premium fast-dry low-VOC paint, SRT (81305) lays smoother. This is the everyday-grade ladder.
Why four sizes?
So a flat close to any face width is on hand — this set sells reach across widths rather than a cut-and-fill method.
How do I clean it?
Warm soapy water up into the heel until clear, then comb straight and hang to dry in shape.
