WHITE ELASTOMERIC ROOF COATING

DESCRIPTION
ALCO MERIC White Elastomeric Roof Coating is formulated using a 100% Acrylic Polymer base that provides outstanding adhesion and superior reflectivity. It is formulated to resist cracking and peeling from severe heat and cold. 

USE
:  Excellent for coating metal, aged galvanized repainted metal, urethane foam, concrete and other approved roof surfaces  

ADVANTAGES
»  Brilliant white color contributes significantly to reducing interior temperatures by reflecting the sun's rays resulting in energy savings  »  Forms rubber-like seal that moves and stretches with normal expansion and contraction of roof surface

PREPARATION
Surface to be coated must be free of oil, dirt and debris. All loosely adhered material must be cut or scraped away. Surface must be power washed then thoroughly rinsed, enabling good adhesion to substrate. On metal roofs, all fasteners must be checked for tightness. Badly rusted panels should be replaced. Slightly rusted areas should be wire brushed and primed with ALCO Red Zinc Chromate Primer. New metal roofs must be allowed to weather for a minimum of 6 months or acid etched if time is essential. On concrete surfaces, be sure all cracks and voids are repaired with a quality patching cement before coating. 

APPLICATION
For best results, apply with a soft brush, roller or airless sprayer. Avoid excessive brushing. Apply at temperatures above 50° F. One coat will normally cover any previous coating but two coats are recommended,. This product has excellent suspension and requires minimum stirring. If roof is hot, spray with water to prevent the coating from drying too quickly. This material may be applied over damp, not wet, surfaces. To obtain the additional strength of a "single-ply" roof, apply a first coat and while coating is still wet or tacky, cover with ALCO Poly-S Polyester Mat. Let dry, then apply second coat.
Apply only when coating will not be subjected to heavy dew or rain before the coating has dried (approximately 5 hours). 
CAUTION: If the coating is rained on or becomes wet before it is thoroughly dry, there is a possibility that the material may dilute and run off the roof onto other surfaces. Should this happen, clean the stained surfaces as soon as possible with soap and water. 
NOTE: Material may be used over aged (over 1 year) BUR and some modified roof systems when ALCO Asphalt and Modified Bitumen Primer is used over existing surface. For Polyurethane Foam, EPDM and aged CSPE-Hypalon™ Systems, see ALCO Reflective and Energy Saving Coatings manual.
