TECHNICAL DATA SHEET

DESCRIPTION
ATOMO is a solvent free water dilutable insulating agent with high penetration, especially suitable for impregnating and consolidating indoor and outdoor mineral surfaces. Formulated with polymers having extremely fine particles, it offers high penetrating power and is able to consolidate wall surfaces especially prone to chalking and already painted with multiple residual layers of old paints.
Thanks to its performance, ATOMO offers a valid alternate solution to using classic solvent-based bonding agents, with the substantial difference that both application and drying take place without producing any volatile organic compound (VOC) emissions.
ATOMO improves cohesion and evens the absorption of the support surface, creating the ideal anchor for subsequent paint layers, isolating them from the alkaline environment typical of concrete and similar surfaces.

INSTRUCTIONS FOR USE
May Be Applied On:

•  Insulating system surfaces.
•  New and old plasters based on hydraulic binders.
•  Concrete surfaces.
•  Gypsum and gypsumboard surfaces.
•  Old paints and wall coatings that are organic or mineral in nature, dry, compact, absorbent and cohesive.
•  Mineral conglomerates of various kinds, as long as they are absorbent.
  

Surfaces should be adequately prepared by following the instructions given in the paragraph "PREPARING THE SURFACE".
Do not apply on freshly painted surfaces.

PREPARING THE SURFACE
Plaster, gypsum and gypsumboard surfaces:

•  Make sure that the surface is thoroughly dried and aged. Resurface or consolidate using specific products if necessary.
•  If mold is present, treat the surface with COMBAT 222 cleanser code 4810222, and with COMBAT 333 reconstruction code 4810333.
•  Brush or wash to remove any efflorescence and any old peeling paint. Completely eliminate any raised layers of lime-based or tempera paints.
•  Remove any dust, smog or other deposits by brushing.
•  Level any irregularities in the surface and treat holes, cracks, crevices and gaps indoor with TAMSTUCCO 9400006/9410110 or STUCCOFACILE 9560019. Use adequate sealants to seal any cracks.
•  Sand putty and touch-ups with sandpaper; remove dust.
•  Smooth if necessary the plaster surface with RASAMIX 9440160 or with BETOMARC 9450150 or RASOMARC 9500150 according to the type of support.
•  Make sure the surface is completely dry and apply ATOMO following the instruction sections.
•  After at least 2 hours, proceed with the application of the finishing product.
  

Concrete surfaces:

•  Buff the surfaces and eliminate any coats of old paint flaking away.
•  If mold is present, treat the surface with COMBAT 222 cleanser code 4810222, and with COMBAT 333 reconstruction code 4810333.
•  Remove any structural concrete parts which are not perfectly adherent.
•  The reinforced-concrete rods protruding from the surface must be thoroughly buffed and treated with BETOXAN PRIMER Passivating grout 9490125.
•  Restore the missing parts with the smoothing coats BETOXAN 400 or BETOXAN 300 Non-shrinking thixotropic fiber-reinforced mortar 9490140/130; perform the final smoothing with BETOXAN 200 Non-shrinking anti-carbonation smoothing coat 9490120.
•  Make sure the surface is completely dry and apply ATOMO following the instruction sections.
•  After at least 2 hours, proceed with the application of the finishing product.
  

Stone or brick surfaces:

•  Dust and clean the surfaces; if there is a layer of dirt, encrusted surface, scales, etc., clean with high pressure water, sandblasting, micro-sandblasting, or chemical cleaning. It is advisable to perform a preliminary test to determine the most effective method and type of cleaning.
•  If mold is present, first treat the surface with COMBAT 222 cleanser 480222 and with COMBAT 333 reconstruction (see corresponding technical information sheets).
•  Make sure that the surface is thoroughly dried and apply a layer of ATOMO following the instruction sections.
  

APPLICATION INSTRUCTIONS

•  Air and support surface conditions: Air temperature: Min. +8 °C / Max. +35 °C; Relative environmental humidity: <75%; Support surface temperature: Min. +5 °C / Max. +35 °C; Moisture level of the support surface: <10%
•  Avoid applying when surface condensation is present, or in direct sunlight.
•  Tools: brush, roller.
•  Nr coats: 1-2 coats are applied, wet on wet. On plasters surfaces, concrete surfaces, sheetrock and plastersboard surfaces the product must be diluted from 50 up to 100 % with water dependig on the support surfaces absorption. On surfaces with presence of old chalcking paint or levelling for thermal insulation, the product must be diluted from 200 up to 300 % depending on the support surface absorption. The correct amount may be determined by observing when an opalescent patina forms on the treated surface. Excessive quantities may form a compat layer that interferes with adherence of subsequent paint layers; on the other hand, too little bonding agent makes it difficult to apply and thus increases consumption, reduces its ability to anchor the finish, and may lead to uneven absorption.
•  Tools must be washed immediately after use with water.
•  Indicative covering capacity:
  

Surfaces with average absorbancy, plasters, smoothing coats, gypsum and gypsumboard: 15-18 sqm/l. Lime based surfaces or very absorbant surfaces: 8-10sqm/l. It is advisable to perform a preliminary test on the specific support surface to determine yield.
