Something old, something new!
A few years ago, we were faced with re-painting the inside of Bruco, our 14,000-square-foot manufacturing facility. The area to be painted was the wall and ceiling, about 21,000-square-foot. So David South, president of Monolithic, led a research team that began looking into the matter.
We began discussing and investigating various products. Then David, someone we knew as an outside-of-the-box thinker, surprised us with his idea.
It involved using whitewash – yes, the old fashioned kind of whitewash – but with an addition. To our whitewash we added a helper: MonoAcrylic, a polymer used in stucco products.
The end result of David’s idea saved us $2,000 and is the best one-coat paint job we’ve seen so far.
This is our recipe:
- Fill a 55-gallon, open-top water drum with water;
- Add 2 bags of lime and mix well;
- Let the lime and water mix sit for 12 hours;
- On the following day, add 1.5 gallons of MonoAcrylic and mix gently;
- Start to apply.
Note: Smaller batches can be made and rolled on.
Letting the lime sit is very important. A sandy layer forms at the bottom of the barrel, and you want it to stay there.
We used our airless paint pump to apply the mixture, and it worked very well. But you have to be careful because the lime mix tends to wear-out the pump’s seals, more than a standard paint will.
MonoAcrylic is a polymer used in a lot of stucco products. Once the coating is applied, the MonoAcrylic keeps the chalky, whitewash coating from rubbing off.
During application, the mixture will not be completely white. Don’t worry! That’s temporary. When the coating dries, it will be very white and will not necessitate a second coat.
Using this type of coating is not only cost effective but healthy. Whitewash has anti-fungal qualities and is commonly used in agricultural applications.
