1ST COAT: BioCalce Classico is a non-aggregate paint and can be used in most
airless sprayers. Dilute BioCalce Classico with 50 – 120% water (7.5 liters of water
per one (1) 15-liter bucket to 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. Parcular 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: BioCalce Classico paint 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 BioCalce Classico. Keep painted limewash walls damp when
applying the 2nd Coat. Use an adjustable spray hose aachment to dampen walls.

1st coat.
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
