27 Fibered Perfectseal Aluminium Exterior Coating

27 Fibered Perfectseal Aluminium Exterior Coating

Available in: 5 gallon pails & 55 gallon drums

KARNAK #27 Fibered Perfectseal Aluminum Exterior Coating is made of selected asphalts and pigment flakes of pure aluminum, blended with petroleum solvents and mineral fibers. When KARNAK #27 Fibered Perfectseal Aluminum Exterior Coating is applied to the roof, the aluminum flakes leaf to the surface, forming a reflective, metallic shield over the base material.

The advantages of this metallic aluminum shield are twofold:

A. The asphaltic oils in the base coating are protected from harmful intense rays of the sun by the reflective properties of the aluminum. Over 50% of the sun’s rays are reflected by this aluminum shield, thereby preventing these oils from being “cooked” out of the base coating. The coating, therefore, retains its resilient characteristics and will not prematurely crack or dry out.

B. During the hot summer months, KARNAK #27 Fibered Perfectseal Aluminum Exterior Coating will help reduce indoor building temperatures and improve inside living and working conditions. KARNAK #27 Fibered Perfectseal Aluminum Exterior Coating prevents the sun’s rays from penetrating the roof coating and passing the heat into the building interior.

The combination of these protective materials – aluminum, asphalt and reinforcing fibers – by the exclusive KARNAK process results in a self-protecting roof coating with longer-lasting heat resistant features. KARNAK #27 Fibered Perfectseal Aluminum Exterior Coating remains tenaciously bonded to the base material, thus assuring longer roof life, with subsequent savings on roof maintenance.

Preparation & Application

SURFACE PREPARATION:
All surfaces should be clean, dry and free of dust, dirt, oil and other foreign matter. Repair all cracks and blisters. New BUR asphalt roof surfaces should weather a minimum of 180 days before being coated with KARNAK #27 Fibered Perfectseal Aluminum Exterior Coating. However, KARNAK #27 Fibered Perfectseal Aluminum Exterior Coating can be coated on roofs 3 to 5 days after KARNAK asphalt emulsions have been applied. Badly weathered or alligatored asphalt surfaces should be
primed with KARNAK 100 Non-Fibered Emulsion or 220 Fibered Emulsion prior to coating with 27 Fibered Aluminum Coating. Allow emulsion primer to cure a minimum of 3-5 days before application of aluminum coating.

APPLICATION:
KARNAK #27 Fibered Perfectseal Aluminum Exterior Coating should be spread uniformly over the roof surface. Care should be taken not to overwork the coating during application. This could have a damaging effect on the leafing of the aluminum. Pour the correct amount of aluminum coating to cover a given area and apply uniformly. Be sure to mechanically mix the aluminum coating thoroughly before using. KARNAK #27  Fibered Perfectseal Aluminum Exterior Coating can be applied with a soft roof brush, roller or spray.
