Why is the paint sold concentrated?
All RomaBio paints are concentrated because of 3 reasons:
1). Reduces our carbon footprint by not adding the water.
2). Longer shelf-life without having to add toxic biocides.
3). It allows the PRO or DIYer to manipulate the product as desired.
What is dilution and how do I dilute the paint with water?
Dilution is adding water to the paint before you apply it. All RomaBio paint products are concentrated and must be diluted with water prior to application. Use a separate mixing bucket and pour the proper amount of paint and water together and mix with a paddle or paint drill 5-10 minutes. The amount of water to use is included in the back instructions of all buckets. Learn more with this How-To video.
Will the color change because the product is being diluted?
No. Color pigments don’t dissolve in water, so when the paint is applied, and water evaporates, the color of the paint remains the same.

What is the shelf life of RomaBio paints?
They have a long shelf life (5-10 years) in concentrate form. Shelf life will shorten if mixed with water, due to impurities in the water you mix it with. It is recommended only to dilute and mix with water the minimum amount of paint you will use and store the remaining concentrated paint separately.

Classico Limewash FAQs
What is ROMABIO® Classico Limewash and why is it unique?
ROMABIO® Classico Limewash is an authentic slaked-lime. It is made from the lime that is mined directly from the Dolomites in Northern Italy, the same source for Venetian plasters. It is aged one year, and then slaked, and then specially formulated into a limewash that gives you durability, but the ability to wash off before it fully calcifies.
Which surfaces can ROMABIO® Classico Limewash be applied?
ROMABIO® Classico Limewash can be applied as 1 coat to create a wash off effect or 1-2 coats for a solid finish to any absorbent, unpainted masonry surfaces including brick, stone, concrete and more. To test for absorbency, throw some water on the surface and see if it soaks up (absorbent), and doesn’t sit directly on the surface (non-absorbent and will not work). (Note: we do not recommend applying it to Exterior horizontal surfaces like a bench or driveway or where there will be heavy foot traffic as it will wear away easily.)
If it is non-absorbent, you can apply ROMABIO® BioGrip Primer as a first coat, then apply 1-2 coats of ROMABIO® Classico Limewash. However, you won’t be able to wash any off and get an exposed brick look.
What colors are available for ROMABIO® Classico Limewash?
ROMABIO® Classico Limewash is available in 7 colors that were curated for the best colors for different styles and color tones of your home. You can order all 7 colors online at homedepot.com or Bianco White and Avorio White are available at select Home Depot stores.
What if I want a custom color for ROMABIO® Classico Limewash? What is the process?
Our local independent retailers can tint custom colors for you. To find one near you, check out Where to Buy to find a store near you or if there isn’t one, call us at 678-905-3700 and we can help you.
Should I use ROMABIO® Classico Limewash or Masonry Paint?
It depends on what you want to achieve. ROMABIO® Classico Limewash is a beautiful whitewash finish that allows you to wash off and expose some of the brick. ROMABIO® Masonry Flat and ROMABIO® Masonry Textured are our most durable coatings for masonry and are designed for longevity with a solid finish. ROMABIO® Classico Limewash is not designed for a solid finish coat with longevity as it will patina and change. However, you can achieve a solid finish with ROMABIO® Classico Limewash if you skip the water wash-off process. For Exterior, we recommend 2 coats, and for Interior, only 1 coat should be needed. ROMABIO® Classico Limewash will shadow when rain or water is applied, and ROMABIO® Masonry Flat and ROMABIO® Masonry Textured will not.
Can I apply ROMABIO® Classico Limewash to painted trim, siding, or various other non-masonry surfaces?
Not directly, but you can use our ROMABIO® BioGrip Micro Primer as a first coat to act as a bridge, and essentially provide a micro masonry surface that will allow our products to adhere. Then add 1-2 coats of ROMABIO® Classico Limewash.
Can I apply it to my driveway/outdoor patio/bench/etc.?
If the surface is horizontal/parallel to the ground and will have anyone sitting or walking on it, then ROMABIO® Classico Limewash will wear away easily and is not recommended.
How do you apply ROMABIO® Classico Limewash to get the wash off effect?
Watch this video from Artistic Finishes.
How many coats do you need?
To get the Old World look of the brick exposed (wash off effect), you only need 1 coat, no additional primer. To get a fully opaque look, 1-2 coats depending on the look you desire.
How many buckets do I need?
It depends on your square footage, how many coats you will use, how absorbent your surface is, and how thick you want the paint. For a wash off effect, you will only need 1 coat. You can use below square footage guideline for most applications.
- 1 QT. size covers 120 SQ/FT (makes 1.5 – 2 QT. after dilution)
- 0.67 GAL. size covers 300 SQ/FT (makes 1 – 1.5 GAL. after dilution)
- 4 GAL. size covers 1800 SQ/FT (makes 6 – 8 GAL. after dilution)
What is dilution and how much water should I add for ROMABIO® Classico Limewash?
Dilution is adding water to the paint before you apply it. You should use 50%-100% water to the amount of paint you are using. If you want a thicker application, then use less water 50%-75%, but if you want it thinner, use 75%-100%. You can always add more water to it after you apply it, so try less water first and see if it’s the look you want. Remember, it’s removeable so you can always wash it off and start over! Check out this video to see how easy it is.
Will my color change because the product is being diluted?
No. The dilution ratio may change the coverage but will not change the color. Pigments don’t dissolve in water, so when paint is applied, and water evaporates, the color of the paint remains the same.
Will ROMABIO® Classico Limewash turn my brick pink after I apply it?
No, ROMABIO® Classico Limewash paint is a fully opaque finish and when it is painted on the brick, it will stay the color of the paint and will not look pink.
My brick is bright orange/red/yellow, will ROMABIO® Classico Limewash cover it?
Yes, ROMABIO® Classico Limewash paint is a fully opaque finish and when it is painted on the brick it will cover the surface completely. It is up to you how much brick/stone/surface that you want to expose so you can cover it completely or wash it off a lot.
Is it really removeable? What if I don’t like it in a couple of years?
Yes, it can easily be removed with a pressure washer (or garden hose after immediate application) in the first 5-7 days. After that, you can use a diluted muriatic acid to remove it. Details in the TDS.
How do you clean a dirty wall with ROMABIO® Classico Limewash on it?
Dirty walls can easily be recoated with another coat of ROMABIO® Classico Limewash or cleaned with soap and water.
Will rain affect ROMABIO® Classico Limewash after I paint with it?
After 3-4 hours of drying, normal rain will not affect the finish due to immediate calcification.
It rained all week and now my home’s brick is soaked. How long before I can paint ROMABIO® Classico Limewash on it?
Because you dampen the surface prior to painting, as long as the temperature is comfortable for you and it has stopped raining so you’re not getting soaked, go ahead with your plans!
What temperature can I apply ROMABIO® Classico Limewash in for the Exterior?
Between 50-90 degrees. You just don’t want it to freeze overnight the first 2 nights after application, and if it’s too hot, it’s too hard to keep the surface damp.
After I applied it, the ROMABIO® Classico Limewash paint looks like it’s not covering?
When you first apply, the paint may appear semi-transparent at first, but it will dry completely to an opaque finish, just give it a little more time.
Will ROMABIO® Classico Limewash solve my efflorescence problem?
No, but Bianco White color for ROMABIO® Classico Limewash has had success blending efflorescence in the past, due to the color being extremely similar in most cases.
Will ROMABIO® Classico Limewash cover-up manganese stains?
No, the stains will bleed through and Classico Limewash is not effective.
Is ROMABIO® Classico Limewash VOC-free?
ROMABIO® Classico Limewash is a lime paint made without toxin ingredients. It is classified as Zero VOC based on U.S. regulation and contains 3.9 g/l of VOC which is below the 5 g/l.
Is there a warranty?
ROMABIO® Classico Limewash is an authentic limewash finish so it will patina as it ages depending on weather exposure. There is no warranty as it is unknown how your limewash finish will change based on your natural elements. But there is no need to repaint unless you want a different look.
What are the Masonry Paints and why are they unique?
RomaBio Masonry Paints are Mineral Paints made with Potassium Silicate. Mineral Paints are different as they have superior durability due to the mineral paint attributes and are toxin-free, naturally mold-resistant and easy to use.
Which surfaces and how many coats do I use for the Masonry Paints?

What is the difference in applying RomaBio Mineral Masonry Paints and traditional acrylics?
There are two main differences:
1). You must dilute the paint with 20% – 30% water prior to the application. See instructions on the back label.
2). You must dampen the surface prior to the application. This can be done as you are prepping the surface with a pressure washer and can paint directly afterward when the surface is still wet, but not dripping.
Will the Masonry Paints cover-up manganese stains?
Potentially, we have done minor testing and have had positive results so far. We don’t know if it will work definitively at this point though.
Is there a Warranty?
20-year limited warranty when applied as a 2-coat system.
How long will it last until I have to repaint?
A really, really long time. If applied properly, you won’t have to repaint for 15-25 years depending on weather and elements exposure.
I want to paint the interior of my house with your product, but it has already been painted. What should I do?
Our Interior paints will cover over most pre-painted surfaces without the use of primer.
Are your Interior paints washable?
Yes, very much so. Matte, Eggshell, and Satin are washable paints.
What ingredients are in your Interior paints?
RomaBio Interior paints are comprised of:
• Potassium Silicate
• Inert Binders (4 – 18% depending on the product)
• Natural Thickeners
• Earth Oxide Pigments (if colored)
What is NOT in your paints?
The list of what’s not included is much more extensive but since we strive to only use the cleanest ingredients these are some that are not included:
• Acrylic Resins
• Toxic Binders
• VOCs and TVOCs
What is Zero VOC paint?
A paint labeled with Zero VOC in the U.S. cannot exceed more than 5 g/L of outdoor VOCs per liter of the VOCs regulated by the EPA Test Method 24.
What is a low VOC paint?
A paint labeled low VOC in the U.S. cannot have more than 250 g/L of outdoor VOCs per liter of the VOCs regulated by the EPA Test Method 24
What is a VOC in regards to the regulation of low and Zero VOC in paints?
The term “VOC” is often used in a precise regulatory context, and its definition is defined by laws. The definition in the U.S. was developed by the Environmental Protection Agency (EPA) to regulate outdoor air and help reduce outdoor pollution due to its effects on global warming. Essentially, the EPA developed a test called the Test Method 24 which determines which VOCs are included in a low or zero VOC emissions in regards to the paint and coatings industry. These VOCs are high weight molecular compounds that are defined in terms of photochemical reactivity or ability to form ozone (or smog pre-cursors) and not toxicity.
Are there other VOCs not included in the regulation that may be adverse to your health?
Yes, certain VOCs are exempt from U.S. regulation because they are not photochemically reactive or smog precursors. The EPA has established a general definition of a VOC that is very broad and it states that “any volatile compound of carbon” is classified as a VOC for regulatory purposes unless it appears on a list of compounds that have been specifically exempted. For example, acetone and ammonia are both volatile and are both organic compounds. They are typically used as solvents in paints. However, if you read the MSDS for the paint you will not find them listed. Another example is methylene chloride and 1,1,1-trichloroethane are not considered photochemically reactive, so they are exempt. But they are associated with adverse health effects.
What about Formaldehyde? Is it safe?
No it is not safe, “in 2011, the U.S. National Toxicology Program described formaldehyde as “known to be a human carcinogen” as stated from Wikipedia.
What are the top chemical offenders that are TVOCs?
This is a complicated issue because there are many ways to look at the impact of a chemical. There is currently no singularity authority in place that will assess the most hazardous or health threatening chemicals. However, some resources will help paint a picture of which chemicals are big offenders. They include:
What is the EPA Test Method 24?
The EPA Test Method 24 is a collection of ASTM test methods that collectively define the VOC content of a coating formulation as defined by the U.S. Environmental Protection Agency. Except the exempt list of compounds or other VOCs, any compound that is “picked up” by these test methods is considered a VOC for regulatory purposes.
Which chemicals are exempt from the VOC regulation?
List of exempt chemicals:
