mold clean up paint
Lime Prime is America's best paint for mold remediation projects. Lou Manfredini showed it to Kathie Lee and Hoda on the TODAY SHOW. Thanks to everyone at NBC for spreading the word!

LIME PRIME - Directly covers mold stains and resists deterioration by mold fungus.  A paint that can be applied directly over Mold and Mildew stains on mold abatement / mold remediation projects. ZERO VOC. This product uses the power of lime instead of conventional chemical biocides like butyl carbamate. Works naturally to keep coated surfaces clean from Mold and Mildew. We've seen it stay clean for well over 7 years! Mineral Based. Breathable.

This is not a paint loaded with excessive chemical biocides and called a mold killing paint. It is a naturally derived mineral paint that is non flammable, zero voc and continues to remain clean from mold even after many chemical biocides loose efficacy. Lime has been used for centuries to kill mold but a lime wash has many disadvantages. Instead of forcing chemical solutions for mold problems, we labored tirelessly to remove all the disadvantages from lime wash. Lime Prime is the result! It's an amazing whitewash primer for the whole house and the best thing we've ever seen for mold clean up projects. No ethylene glycol!

RECOMMENDED FOR: Mold Abatement Projects, Flood Damage, Mold / Mildew Clean up Projects, Drywall (front and back), Basements, Schools, Hospitals, Surgery Centers, Crawl Spaces, Attics, Inside Wall Cavities, Interior Walls, Wineries, Museums, Antiques Storage, Yurts, Indoor Pool Areas, Boats, Flood Zones, Commercial Properties, Flood Clean Up Projects, Rental Properties...

Smooth Surfaces: 250-350 Sft. / Gallon (such as painted drywall.)

Rough Surfaces: 100-250 Sft. / Gallon (such as uncoated concrete block).

Sprayed in Wall Cavities: Approx 275 Sft. / Gallon (diluted with 1 gallon water per Five Gallon Pail).

STIR: Stir with a drill mixer for 3 minutes or until creamy. It is a thick product and Lime can thicken sometimes in the can. It always mixes up into a nice creamy consistency with a good mixing. A stirrer stick or whisk can also be used but takes longer. Pouring the product back and forth into an empty container is another way of mixing. Of these methods a simple paint mixer attachment on a drill is the easiest. 

APPLICATION: Brush, roll or spray. Apply one coat for most areas. Apply two coats for severe areas. 

DILUTION: None necessary. If spraying dilute by adding 1/2 to 1 Gallon of water to 4 Gallons Lime Prime as needed. Gallons can be diluted 1/2 to 1 quart of water per gallon as needed. It is not recommended to exceed a 4:1 ratio.


ODOR: Low. Lime Prime has been found to eliminate musty odors in some of the most severe cases. 




UNCOATED: Lime Prime is a primer. It is intended to be topcoated. However, over time the product has proven quite useful when 1 or 2 coats are applied directly over the surface and not top coated. These scenarios are briefly described below. Always test first if you intend to leave Lime Prime uncoated in a living area where the appearance is important. 

TOP COATING: Can be painted over with any common paint (test color and paint first). In areas with severe moisture issues such as basements, flood zones etc. it may be best to use two coats and leave Lime Prime uncoated. For bathrooms, windows and exterior uses with severe moisture / mold issues it is best to apply two coats of Lime Prime and 1 or 2 coats of Clear Skies Satin as the final coat. This provides superior surface film protection that can be easily washed and maintained.

BREATHABLE: When considering top coating it can help to consider how much breath-ability is desired on the surface. One of Lime Prime's great strengths is that it is breathable. It won't trap moisture. Sometimes this is exactly what is needed. On other projects a vapor barrier is the best choice. We can help you make this choice on a project by project basis.

A few general guidelines are:

1. FULL BREATH-ABILITY: Basements, crawl spaces, attics and other such areas usually get one or two coats of Lime Prime and no top coat. Most often these areas have Lime Prime sprayed directly over the mold stains. 2. VAPOR BARRIER: This is the more complex of the three scenarios. Mold infested wood / drywall with constant moisture exposure can colonize mold spores internally. In this scenario, a breathable coating is not the best approach since it won't stop moisture from passing through the deeper areas of the surface. We top coat Lime Prime to seal the surface. It is best to use 1-2 coats of Clear Skies Satin or NanoTech over Lime Prime in these situations. This helps keep the wood dry internally, thus preventing the moisture from getting into the wood. Moisture can feed mold.  Bathrooms, some window trim, some exterior wood, blue stain infested woods are generally surfaces that fall under this scenario. Being able to wash away food sources for mold is the key here (dirt, grease, oils, shower steam carried dead skin, dust), we use Earth Clean to clean the surface. Cleaning is a vital step in preventing mold growth. In areas where these things accumulate frequently, it is more important to remove the food source for mold. The reason is that, even if mold spores die on the coated surface, they are crafty buggers and will actually build a bridge above the surface to colonize upon. So, having a way to keep the surface clean in certain areas that will get constant debris and moisture exposure has proven invaluable when trying to prevent mold growth.  3. SEMI BREATHABLE: Very often Lime Prime is applied directly over mold stains and Clear Skies Eggshell is applied as the top coat. This remains semi breathable and some of the Lime Prime qualities are able to remain in effect. Moisture vapor can pass through to some extent but if it rains or you sprayed the wall with a hose the coated surface would remain protected and fairly dry. However, moisture vapors that were trapped inside the wall cavity have a good chance to pass through slowly without causing peeling or rot internally.  PAINTING LIME PRIME OVER EXISTING PAINT: It is best to try a test area first to insure compatibility. Lime Prime coats latex paints well and we have not had any issues reported for this use. Is covers many oil based paints also but there are too many varieties to say it is safe to coat any oil based paint. Scuff the surface with sandpaper to provide tooth, wash and apply a test area. Testing first will reveal if Lime Prime is compatible with the existing coating. Sometimes it takes a little extra consideration to find the best approach. Clear Skies employs an oil based coalescent which assists in it's compatibility when coating oil based coatings. But again here a test needs to be done first.

LIMITATIONS: Do not use on Aluminum. Not a stain blocker for severe stains. Sample pints are recommended for testing in advance. 

"Thanks for creating and selling Lime Prime! Was so helpful when a certain DIY "noob" (ahem) with limited mobility took on a very sudden quasi-remediation after several infamous hurricanes did some redecorating. With under a thousand dollars to work with (aka no professional help) and a complete inability to get close enough to scrub even just visible mold, I got a Graco and a five-gallon bucket from you guys and went to town. Several years later, I've been promoted to "Official Bob Vila Wanna-be," and preach to everyone I meet about Lime Prime. Thanks so much again for doing what you do to help us ALL keep doing what we do... for a whole lot longer than we might otherwise be able to. The Brightest of Blessings to you all! :) SB"
