The short version
- German schmear = mortar, textured, permanent, old-world.
- Limewash = mineral paint that soaks in, soft and chalky, can be partly washed off when fresh, fades gracefully.
- Whitewash = thinned latex paint, flat and even, quick and cheap, essentially permanent.
- None of them work well over already-painted brick except paint itself.
After we posted our German schmear fireplace, the most common question in my inbox was some version of: "Should I schmear, limewash or whitewash my brick?" They all lighten brick and they're all doable as DIY projects - but they look, wear and age very differently. Here's the honest comparison I wish I'd had.
The quick comparison
| German schmear | Limewash | Whitewash | Paint | |
|---|---|---|---|---|
| Material | Wet mortar | Slaked lime + water + pigment | Latex paint thinned with water | Masonry paint |
| Look | Textured, chunky, old-world | Soft, chalky, mottled | Flat, even, translucent | Solid, uniform |
| Brick showing | As much as you leave | Adjustable while wet | Even all over | None |
| Reversible? | No | Partly, for a few days | No | Only by stripping |
| Breathable? | Yes | Yes | Somewhat | Depends on product |
| DIY difficulty | Medium | Easy-medium | Easy | Easy |
| Fireplace cost | $40-$90 | $50-$100 | $25-$50 | $40-$80 |
German schmear: texture and permanence
German schmear (or German smear) is wet mortar spread over brick and partly wiped back. Because it's mortar, it adds texture and dimension - the joints fill in, the edges soften and the whole thing reads like old European stonework. It's the most dramatic transformation of the three and the most permanent: there's no going back once it cures.
Choose it if: you want a rustic farmhouse or French cottage look, you love texture and you're sure.

Limewash: soft, chalky and forgiving
Limewash is one of the oldest finishes there is - slaked lime mixed with water and natural pigment. It soaks into the brick instead of sitting on top, creating a soft, cloudy, almost velvety finish. While it's still fresh (usually the first day or two), you can wash some of it back off with water and a brush for a more worn look. Over the years outdoors it weathers gradually, which many people love.
Choose it if: you want something subtle and organic, you like the idea of being able to adjust it, and you don't mind a refresh coat down the road.
Whitewash: quick and even
Whitewash is simply latex paint thinned with water (around 1:1) and brushed on, then wiped back with a rag. It's the fastest and cheapest option and gives a uniform, translucent finish where the brick color shows evenly through. It doesn't add texture.
Choose it if: you want a cleaner, more modern lightened brick on a budget, and you're doing an interior fireplace.
What about painted brick?
Paint gives total coverage and the cleanest, most modern look - and it's the only option of the four that works if your brick is already painted. Use a breathable masonry paint, especially outside. We painted the fireplace in our first house and it was the right call there.
German schmear and limewash both need bare, porous brick. They won't bond to painted or sealed brick.
So which did we choose - and would we again?
For our 1960s brick fireplace, German schmear was exactly right: it made the room brighter, added the texture the space was missing and still feels warm instead of stark. For the exterior of the house we're leaning toward limewash, because it's breathable, more forgiving on a big surface and ages beautifully.

Frequently asked questions
Which lasts longer, limewash or German schmear?
German schmear lasts the longest - it's mortar, so it's essentially as permanent as the brick. Limewash weathers and patinas over 5-7 years outdoors (less indoors) and can be refreshed with another coat.
Is limewash cheaper than German schmear?
They're similar for a fireplace - roughly $40-$100 either way. Limewash costs more per gallon but goes further; German schmear uses inexpensive mortar but more of it.
Can you limewash over German schmear?
Yes. Limewash bonds to mortar, so you can tone down or brighten a German schmear finish with a limewash coat.
Which is best for a brick house exterior?
Limewash and German schmear are both breathable and well suited to exterior brick. Whitewash made with latex paint can trap moisture over time, so use a masonry-specific product if you go that route.
