Is the black a tinted product?

No. KST041325 is a catalog color of the premium acrylic elastomeric, supplied black. The accent, deep and pastel tint bases are separate part numbers, tinted with the manufacturer colorant system for a matched or shaded roof.

Should the roof be black or white?

That is the owner's and the specifier's call, and a dark finish and a light one do not behave the same in the sun. If the building is working to an energy target, take the figures for the colors you are comparing from the manufacturer's product data sheet, because that is the only place they are stated. We stock whichever color the specification names.

What base coat goes under it?

The gray premium acrylic KST041320 on metal, concrete and foam; the elastomeric MB base coat on smooth BUR, modified bitumen and cap sheets; the single-ply base coat on weathered EPDM (after the wash primer), TPO and Hypalon (after a pressure wash). The data sheet for the system decides.

How much will my roof take?

The manufacturer's product data sheet states the coverage rate and the film build per coat and per substrate. Send the square footage, the roof type and its condition and the quote works the pails or drums out for that roof.

Do you handle the system warranty?

No. Sherwin-Williams issues its system warranties through its own authorized contractors on its own terms. We supply the materials, and the goods are warranted to match their description.

Overview

KST041325 is the premium acrylic elastomeric finish coat in black. Chemistry, grade and substrate list are the white’s: 100% acrylic elastomeric, water-based, listed by the manufacturer over metal, polyurethane foam, concrete, smooth built-up, modified bitumen, granular cap sheets, EPDM and Hypalon, and listed for use with fabric or seam tape at the details.

Black is a catalog color, not a tint, which is the practical reason contractors ask for it: it comes out of the pail ready and the pail says what is in it. It shows up on visible roof decks and canopies where a white field would be wrong, on accent and curb work beside a light-colored roof, and on jobs where the owner has simply specified a dark finish. Rates, film build, recoat and cure come from the manufacturer’s product data sheet.

Application

Start on a roof that is clean, dry and sound. Wash the field, clear ponded silt and loose granules, then let it dry as the data sheet requires.
Repair first, then reinforce the details before the field goes on: splits, blisters, open laps, flashings, penetrations and fastener rows.
Prime by substrate. Metal, concrete, single ply and asphaltic surfaces each take their own first step off the data sheet.
Base coat, then finish coat. A contrasting base color under the black makes each pass visible while it is being applied.
Apply at the rate, film build and coat count the manufacturer’s product data sheet states, in the conditions it allows.

Ordering

KST041325 comes in 5-gallon pails and 55-gallon drums. Stocked pack sizes ship in 1 to 3 business days; anything not on the shelf is ordered in and runs 1 to 2 weeks. Drums, pallet quantities and freight go through the quote form, and every price is quoted per project rather than printed here. Send the part numbers, the quantities, the site ZIP code and your dates, and we reply with the price, freight to the site and a ship date.

Where it's used

Roofs that stay dark by design

Visible low-slope roofs, roof decks and canopy areas where the architect or the owner has asked for a dark finish rather than a white one.
Metal roofs

Panel and standing-seam roofs, once the fasteners are dealt with, the metal has taken its primer and the ribs and fastener rows have been detailed.
Smooth BUR, modified bitumen and cap sheets

Sound asphaltic roofs, over the elastomeric MB base coat those surfaces take before an elastomeric finish coat.
Aged single-ply and foam

Weathered EPDM and Hypalon over the single-ply base coat, with the wash primer first on EPDM only, and SPF roofs at their recoat interval.
Detail and accent work

Curbs, upstands, equipment screens and small areas finished in black beside a light-colored field, using one coating chemistry across the whole roof.
