GENERAL LIMEWASH APPLICATION
INSTRUCTIONS & TECHNIQUES
(For detailed diluons and instrucons for specic type of surfaces including new
and painted drywall/wood, please see APPLICATION CYCLES ON DIFFERENT
TYPES OF SURFACES).
Stone & Brick LIMEWashES
BRUSH APPLICATIONS
When applied to natural mineral surfaces such as stone, brick, or NHL 3.5 cements
Classico Limewash can be applied as an anque wash o (limewash), rst dilung
the product with water then applying on a per-dampened surface with a large
masonry brush used for lime paint.
Technique requires sucient pre-weng with water of the masonry surface for
un-painted brick or stone to permit a slow set with the limewash applicaon.
Classico Limewash must be diluted with water between 100 – 150% to permit
sucient lime paint material to remain.
Tesng must be determined by several aempts at dierent diluons of lime
paint with water, as well as surface heat condions, water pressure, and type of
spray p (wide or narrow), to remove the correct amount of lime paint to create an
accurate historical eect. Then, you can begin washing with an adjustable spray
hose with at least 55+ PSI pressure, remove the amount of desired paint material
without over or under washing. Occasionally, 2 – 3 types of diluon are required
to create the desired eect, requiring several coats, with sucient drying me in
between. Correct applicaon and removal will provide a historical washed paint
eect for new or exisng construcon.
1ST COAT: Dilute Classico Limewash with 100% water, 15 liters of water per one
(1) 15-liter bucket to 150% diluon, 22.5 liters of water per one (1) 15-liter bucket.
For 1 liter sizes: Classico Limewash diluted with 100%, 1 liter of water per one (1)
liter product, Classico Limewash diluted with 150%, 1.5 liters of water per one (1)
liter product.
Diluons with water are suggested as general guidelines for applicaon, but
paint applicator may adjust diluons as needed to meet best uses for ease of
applicaon, job site requirements and nishes.
PRE-WETTING: 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. Do not apply paint
to overly wet/dripping surfaces. Brick walls should be weed down with water
several mes.
APPLYING WITH A BRUSH: Apply the pre-diluted Classico Limewash with a large
masonry brush, starng applicaon at the top of the pre-dampened wall, working
with the brush le to right, right to le (for brick courses), and for stone apply in
a criss-cross paern. Back brush as necessary to remove runs from the vercal
mortar joins, and connue this applicaon as rapidly as possible, moving down the
wall to the ground level. Time allowance for a whole wall coverage with limewash
is generally 30 - 40 minutes. Try to work in whole wall secons, corner to corner,
top to boom. It is recommended to not paint masonry surfaces exposed to full
midday, direct sun exposure. Depending on heat and direct sun, me may be
reduced to 10 - 15 minutes.
USING THE SPAY HOSE: Once the limewash begins to pull or dry, usually
indicated with 50% of each brick or stone, half white (indicates dry), and the other
half wet (darker/wet), it is the ideal me to begin using an adjustable hose spray
(handle type with a plasc p adjustment), to wash o the lime paint in short
bursts, narrowing or broadening the spray p as required to remove the quanty
of limewash desired, and controlling the force of the spray by the pressure handle.
GENERAL METHODS FOR ACQUIRING ANTIQUE EFFECTS: Typical anque
methods are based on observaons of me-worn lime painted surfaces. Meaning
that environmental erosion by sun, wind, rain, occurs more rapidly on brick or
stone areas not protected by eve overhangs and roofs, and typically the upper half
secons of the walls will be less worn than the boom half secons of the wall
toward the ground (where runo from the wall above and back splashing from the
ground cause deterioraon to occur more rapidly). It is important that the overall
anque look of the limewash is gradual and appears natural. Observe your results
oen from afar, so that you can see the eect of the limewash from a distance.
2ND COAT: 2nd coats are required only when necessary, where perhaps too
much lime paint was removed in one area and a touch up is required. Always re-
wet the dried surface areas with water, then applying the limewash starng at the
center of the area and move out to the sides, overlapping with as lile limewash as
necessary where you do not need to touch up. It is suggested to use a 2nd clean
brush with only water to feather out the overlap so that as the limewash dries, the
touch up will not be visible. Allow the touch up to dry as indicated above and rinse
o with the spray p to re-create the nish technique you have adapted.
Touch ups may require greater diluon of Classico Limewash than when used
for the 1st coat. If the standard diluon you used was 100% with water, a small
quanty of Classico Limewash should be diluted with water at 150%, or 1.5 lts of
water to one (1) liter of product.
3RD COAT: 3rd coat applicaons usually serve to create more dynamic
dimensional nishes, such as applying a 150 - 200% diluon with water and
re-coang areas under roofs, roof eves, under brick row locks, ledges, or in higher
upper wall secons to help create depth. It is suggested to only cover narrow
areas, applying as needed to create a slightly thicker look than the main wall areas.
Follow the touch up instrucons indicated in the 2nd Coat above.
Applicaons should not be performed in air temperature lower than 13°C / 55°F
and not above 32° C / 90°F.

BRUSH APPLICATIONS
PRIMER: For interior or exterior applicaons where the surface base to be
painted is a non-mineral surface (i.e., acrylic paint, drywall, portland cement
stucco, wood), apply 1 coat of BioGrip Micro or Medium, applying generously, and
allow to dry for 8 – 12 hours prior to applicaon of 1st coat Classico Limewash.
1ST COAT: Dilute Classico Limewash with 50% water, 7.5 liters of water per one
(1) 15-liter bucket to 120% diluon, 18 liters of water per one (1) 15-liter bucket.
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. Do not apply paint to overly
wet surfaces. Allow 1st coat to dry for at least 2 – 8 hours before applying 2nd
coat. Brush, roll or spray the rst coat. Using a large brush and painng by hand
will create the best results. Classico Limewash can be applied to non-acrylic
painted natural mineral surfaces such as stone, brick, NHL stucco lime plasters,
without the use of a primer.
2ND COAT: Apply Classico Limewash diluted with 50% water, 7.5 liters of water
per one (1) 15-liter bucket to 120% diluon, 18 liters of water per one (1) 15-liter
bucket. Classico Limewash should be applied wet on wet. This means that the
brick or stone surface should be dampened throughly with water before the
applicaon 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 aachment to dampen walls.
Apply with brush when possible. Painng with a brush in a crisscross paern will
create a very slight natural chromac nish. Allow 2nd coat to dry for at least
1 – 4 hours before applying a 3rd coat.
3RD COAT: For wash or glaze aects Classico Limewash can be diluted from 150
– 200% with water. Extreme diluons for the exterior should be applied on 1st
or 2nd base coats only. Always paint wet on wet. It is suggested to nt your lime
paint darker or lighter for glaze eects.
Diluons with water are suggested as general guidelines for applicaon, but
paint applicator may adjust diluons as needed to meet best uses for ease of
applicaon, job site requirements and nishes.
