Why does the product line matter if the brand is good?

Because every major maker sells several lines at very different levels, from contractor-grade to premium, for different surfaces. Knowing it is Sherwin-Williams or Dunn-Edwards tells you the maker. The product line tells you what the coating is designed to do, how it should be applied and how long it is meant to perform on your kind of surface.

Does every surface need primer before painting?

No, but more surfaces need it than people expect. Bare wood, stucco repairs, patched drywall, stains that bleed through and rusting metal all generally call for a primer suited to them. Sound, clean paint in a similar color often does not. A good estimate says where primer goes rather than leaving it to judgment on the day.

Should I keep the leftover paint after the job?

Yes, if it is labeled. A sealed can marked with the product, color formula, sheen and the room or surface it went on makes future touch-ups match far better. Store it indoors, away from heat and frost, and ask the painter to write the details on the lid before he leaves.

Can I ask to see the cans on site?

You can, and a careful painter will not mind. Seeing the labels lets you confirm the product, sheen and color match the estimate. It also gives you the manufacturer's application conditions, including the temperature range and recoat time, so you know what the work should look like day to day.

What to Ask About the Paint in a Bid

Ask which maker and product line is proposed for each surface, whether it is made for that surface, what primer goes where, which sheen, how many coats, and what the label says about temperature, humidity and cure time. Then ask how the color formula will be recorded and whether the leftover paint stays with you for touch-ups.

An estimate that says “two coats of premium paint” has told you almost nothing about the paint. Premium compared with what, from which maker, made for which surface? The paint is a small share of what a job costs, but it is a large share of how long the result lasts, and it is the part of the estimate homeowners are least likely to question.

These are the questions worth asking, in roughly the order a painter would think about them.

Which maker, and which product line?

Start with the name on the can. Then go one level further, to the product line, because each major maker sells a range of them at very different levels. Sherwin-Williams, for example, sells lines such as SuperPaint, Duration and Emerald, and its Loxon products are designed for masonry. Dunn-Edwards has lines such as Spartawall, Evershield, Aristoshield and Suprema. Those are examples of categories, not a recommendation for your house; the point is that “Sherwin-Williams” or “Dunn-Edwards” on its own is not yet an answer.

Lemoon’s Painting uses Dunn-Edwards and Sherwin-Williams, chosen for quality, finish and fair value, and Ebenezer prefers to supply the paint himself, so the product on the wall is the one he proposed. Ask him which product he proposes for each surface and why.

Is it made for this surface?

Stucco, wood trim, metal railings, interior drywall and a front door are different materials, and coatings are formulated for them. Ask whether the product proposed for each surface is designed for it. Stucco and masonry move and breathe differently from wood; galvanised or ferrous metal needs a coating that will hold to it; an interior product does not belong outside. If your stucco has active hairline cracking, ask whether an elastomeric coating is being proposed and why; there is a fuller comparison of elastomeric and acrylic on stucco.

What primer, and where?

Primer is where estimates go quiet. The honest answer names the surfaces that get it: bare or scraped wood, every stucco and drywall repair, water or smoke stains that would bleed through, and any rusting metal. New or freshly patched stucco also has to cure before it is primed, and the primer label gives the conditions. Sound, clean paint in a similar color often needs no primer at all. What you want to hear is a list, not “primed as needed”.

Which sheen on which surface?

Sheen changes how a surface looks and how well it can be washed. Stucco body, trim and doors usually get different sheens, and so do ceilings, walls and kitchen or bathroom surfaces inside. Ask for the sheen for each surface in writing. The trade-offs are covered in the guides to exterior sheens and interior sheens room by room.

How many coats, and applied how?

Every label gives a coverage rate, and a coat spread far thinner than that rate is not the coat the maker designed. Ask how many finish coats each surface gets and whether the paint will be thinned. On a big color change, ask whether a tinted primer or an extra coat is part of the plan. Spray or brush is decided per job, with your preference first; either way, the film on the wall is what protects it.

What does the label say about the weather?

Each label states the temperature range for application and the drying, recoat and cure times, and many also say how damp the air or the surface may be. Ask how the schedule respects them. In Imperial Beach and the rest of the coast, the questions are morning dew, salt film and damp walls after a wash. Inland, in Spring Valley and East County, it is surface heat on west walls in the afternoon. A painter who knows the label plans the day around it.

Does it resist mildew and salt where you need it?

Shaded north walls, walls behind dense planting and anything near the water are prone to mildew. Ask whether the product is formulated to resist it and, just as important, whether existing mildew will be killed and washed off first. A mildew-resistant paint over live mildew is not a fix.

Is the color the maker’s own, or a match?

A color can be mixed from the maker’s own system or matched from another company’s chip. Matches are usually close, but not always identical, especially in deep colors. Ask which it is, and ask for the formula to be recorded.

What happens to the leftover paint?

Ask for the remaining paint to be left with you, sealed and labeled with the product, sheen, color formula and where it went. It is the most useful thing you will have when a scuff or a repair needs touching up two years from now. And ask whether you can see the cans on site; a painter with nothing to hide will hand you one.

Put the questions to Ebenezer

None of these questions is awkward to a painter who has thought about your house. Ebenezer chooses the product for the surface and will explain why. Ask for a free estimate and bring this list with you. More on exterior painting, or on what to ask a painting contractor beyond the paint itself.
