classico Limewash Technical Data Sheet TDS
TM
PRIMER COAT: Apply at least one (1) coat of BioGrip Micro or Medium primer as
indicated in GENERAL APPLICATION INSTRUCTIONS.
1ST & 2ND COATS: Apply two (2) coats of Classico Limewash according to
GENERAL APPLICATION INSTRUCTIONS. For FULL COVERAGE it is advised to
use BioCalce Flat Lime paint.
ADOBE BRICK
INTERIOR / EXTERIOR: Adobe brick being made of a composite of dirt/sand
and inorganic material is extremely suscepble to damages caused by water on
exterior surfaces. Potassium silicate paints are ideal because they will carbonize
to mineral content in the clay brick, creang consolidaon, strengthening the
external surfaces and allow them to be water resistant and permeable when
painted with BioDomus I.
PRE-PRIMER COAT: For best results apply Potassium Silicate Concentrate, diluted
100% with water, o (1:1), or 10 liters of water per one (1) 10 liter bucket as a pre-
primer, on all new, unpainted surfaces, applying 2 – 3 coats in rapid succession,
wet on wet, unl substrate has arrived at full absorpon, and allow to dry for at
least 2 -3 days.
PRIMER COAT: Apply at least one (1) to two (2) coats of BioGrip Micro or Medium
primer as indicated in GENERAL APPLICATION INSTRUCTIONS.
1ST & 2ND COATS: Apply two (2) coats of Classico Limewash according to
GENERAL APPLICATION INSTRUCTIONS. For FULL COVERAGE it is advised to
use BioCalce Flat Lime paint.
AUTOCLAVED AERATED CONCRETE
INTERIOR / EXTERIOR: Autoclaved aerated concrete cannot be painted,
plastered or stuccoed directly onto non-consolidated and unprimed surfaces.
Using ROMABIO Specialty Products and Primers applied onto autoclaved aerated
concrete will permit the proper applicaon of any type of paint, plaster or stucco
to be applied the surface.
PRE-PRIMER COAT: It is recommended to apply one (1) coat of Potassium Silicate
Concentrate diluted 100% with water, or 10 liters per one (1) 10 liter bucket,
applying wet on wet, applying 2 – 3 coats in rapid succession unl aerated
concrete has completely and evenly absorbed the Potassium Silicate Concentrate
into surface. This process will double the strength and durability of the surfaces
of aerated concrete, as well as increase adhesion of any type of applied material.
Apply Potassium Silicate Concentrate with a brush, roller, or sprayer and allow to
dry for 2 – 3 days.
PRIMER COATS: Apply at least two (2) coats of BioGrip Micro primer as indicated
in GENERAL APPLICATION INSTRUCTIONS.
1ST & 2ND COATS: Apply two (2) coats of Classico Limewash according to
GENERAL APPLICATION INSTRUCTIONS. For FULL COVERAGE it is advised to
use BioCalce Flat Lime paint.
Decaying or Crumbling Stuccos or Powdery
Surfaces
INTERIOR / EXTERIOR: Chalking surfaces, which could prevent the proper
anchoring of the base coang must have damaged and chalky porons be removed
by pressure washing and scraping. If pressure washing is not an opon for interior
surfaces, scrub aected areas with a s brush and white vinegar or muriac acid
(1 part muriac acid and 6 – 7 parts water), and aer 3 -5 minutes rinse several
mes with a large sponge and clean water.
PRE-PRIMER COAT: For unpainted stuccos apply Potassium Silicate Concentrate
diluted 100% with water (1:1) on all damaged surfaces, or 10 liters of water
to one (1) 10 liter bucket, applying wet on wet, applying 2 – 3 coats in rapid
succession, unl substrate has arrived at full absorpon, and allow to dry for at
least 2 – 3 days. For old, acrylic-free painted stuccos, apply one (1) coat EcoForte
Consolidator diluted 100%, or 10 liters of water to one (1) 10 liter bucket, and
allow to dry for at least 8 – 12 hours.
PRIMER COAT: Apply one (1) coat of BioGrip Micro, as a primer nted if required*,
with brush, roller or approved sprayer for ne aggregate, diluted 30% with water,
or 4.5 liters per one (1) 15 liter bucket, and allow to dry for at least 8 – 12 hours.
For severe cases of deterioraon, take into consideraon the removal and
replacement of damaged stucco in its enrety. Cement stuccos exisng prior to
1940 are probably made of NHL 3.5 or 5.0 (Natural Hydrated Lime Cement) and
careful inspecon and aenon needs to be taken to ensure proper replacement
and repairs. At all costs, avoid using portland based cements for restoraon or
repairs on NHL cements.
1ST & 2ND COATS: Apply two (2) coats of Classico Limewash according to
GENERAL APPLICATION INSTRUCTIONS. For FULL COVERAGE it is advised to
use BioCalce Flat Lime paint.
Coatings with Efflorescence
INTERIOR / EXTERIOR: Cement surfaces showing eorescence should be
aggressively cleaned with a high pressure washer or s brush, and then the
eorescence should be treated using a diluted muriac acid, 1 part muriac acid
and 6 – 7 parts water, and allow to react for 3 – 5 minutes. Thoroughly rinse
treated areas with water and allow to dry.
PRE-PRIMER COAT: Apply Potassium Silicate Concentrate diluted 100% with
water (1:1), or 10 liters to one (1) 10 liter bucket, on all damaged surfaces and allow
to dry for at least 12 – 24 hours; or apply one (1) coat of EcoForte Consolidator
diluted 100% with water, or 10 liters to one (1) 10 liter bucket, and allow to dry for
at least 8 – 12 hours. This applicaon applies only to unpainted, or mineral painted
surfaces only.
PRIMER COAT: Apply BioGrip Micro primer, diluted with water 30%, or 4.5 liters
per one (1) 15 liter bucket, and allow to dry for at least 8 – 12 hours.
1ST & 2ND COATS: Apply two (2) coats of Classico Limewash according to
GENERAL APPLICATION INSTRUCTIONS. For FULL COVERAGE it is advised to
use BioCalce Flat Lime paint.
Aged Cement Stuccos
INTERIOR / EXTERIOR: Dirty and/or contaminated surfaces should be treated as
a priority prior to any intervenons of replacing or repairing stucco. All surfaces
should be cleaned and any aached algae removed manually or by mechanical
means, i.e., with a high-pressure washer. Stucco damaged by algae or mold should
be treated with EcoDis aer pressure washing. These instrucons are based on
unpainted portland based type cement stuccos.
PRE-PRIMER COAT : When new stucco repairs are performed on older, unpainted
cement stuccos, complete all removal of damaged stucco, rinse surfaces of dust,
and apply EcoForte Consolidator to older surfaces prior to applying new cement
stucco or make repairs. Pre-prime exisng surfaces applying one (1) coat of
EcoForte Consolidator diluted 100% with water, or 10 liters to one (1) 10 liter
bucket, and allow to dry for at least 8 – 12 hours.
PRE-PRIMER COAT / REPAIRS: Allow new cement repairs to fully dry and cure
according to instrucons indicated under secon; NEW CEMENT STUCCOS.
Apply EcoForte Consolidator diluted as indicated onto any new stucco repairs and
allow to dry for at least 8 – 12 hours.
PRIMER COAT / INTERIOR / EXTERIOR: Apply one (1) coat of BioGrip Micro
primer as indicated in GENERAL APPLICATION INSTRUCTIONS. Where repairs
require the applicaon of BioCement 1.0 GF, it is suggested to use BioGrip
Medium primer.
1ST & 2ND COATS: Apply two (2) coats of Classico Limewash according to
GENERAL APPLICATION INSTRUCTIONS. For FULL COVERAGE it is advised to
use BioCalce Flat Lime paint.
