Roller Applications

Paint Sprayers
FULL COVERAGE
1ST COAT: Classico Limewash is a non-aggregate paint and can be used in most
airless sprayers. Dilute Classico Limewash with 50% water, 7.5 liters of water
per one (1) 15-liter bucket to 120% diluon, 18 liters of water per one (1) 15-liter
bucket when applying paint to achieve a full coverage nish. For brick or stone it is
required to pre-wet all masonry surfaces with water thoroughly to facilitate slow
drying of the limewash. This also assists limewash paints to absorb deeper into
the masonry surface. It is suggested to dampen previously all masonry surfaces
with water thoroughly, so as to assist lime wash paints to absorb deeper into the
masonry surface. Do not apply paint to overly wet surfaces. Allow 1st coat to dry
for at least 2 – 8 hours before applying 2nd coat. Parcular care must be taken
when using a sprayer on brick or stucco to apply product abundantly, without
causing paint runs, so as to permit proper millage thickness for longer durability.
2ND COAT: Classico Limewash paint should be applied wet on wet. This means
that the brick or stone surface should be dampened throughly with water before
the applicaon of the 1st Coat, and the same with the 2nd Coat when applying
onto the 1st Coat of Classico Limewash. Keep painted limewash walls damp when
applying the 2nd Coat. Use an adjustable spray hose aachment to dampen walls.
Dilute Classico Limewash with 50 – 120% water, and apply as instructed above for
1st coat.
Diluons with water are suggested as general guidelines for applicaon, but
paint applicator may adjust diluons as needed to meet best uses for ease of
applicaon, job site requirements and nishes.
SPRAY TIP USAGE: Classico Limewash may be applied using an airless sprayer.
Apply paint product with a # 0.019 – 0.021 mm size spray p. Always use new
spray ps for starng a paint job for best results. This will also conserve the
amount of paint necessary to complete the job.
GRAIN SIZE: 0.01 mm
MIXING PAINT & WATER
ROMABIO BioCalce lime paint formulas are concentrated and require water to be
added to them for proper use. This process means we can sell more coverage in
an economical package that decreases the cost for transport, reduces the carbon
footprint, and is less impact to the environment.
Mix paint and water with an electric drill and paint paddle, or mix well by hand! If
water is sing on the top of your mixture, the paint is not properly mixed!
TOOLS
Apply with an appropriate masonry brush composed of synthec bristles or with
an appropriate sprayer and sprayer p. Paint rollers cannot be used to apply
BioCalce lime paints.
TOOL CLEANING
Brushes, sprayers, rags, or sponges should be cleaned immediately aer use with
water and a mild detergent or dish soap.
DRYING TIME
For Wash O Eects, the Limewash applicaon is generally a 1 coat process,
but a 2nd or 3rd coat may be applied for decorave eects. Allow newly applied
limewash to set 10-40 minutes depending on temperature and sun. Wash o
process can begin when bricks appear half wet/half dry, before painted surface is
completely dry to the touch.
For Full Coverage Applicaons, allow a drying me between coats of at least
2 – 8 hours for the 1st coat, and with successive coats allow at least 1 – 4 hours
between coats. With lower temperature and humidity more me may be needed.
Do not apply Classico Limewash on the exterior if there is a risk of severe
thunderstorms or showers during the 12-hour drying me needed for product to
dry and carbonize correctly.
