and door mullions.

SC9100 DTM Epoxy Mastic

Substrates: DTM or to concrete.

ROC Prime 100

Substrates: All surfaces

Note: Lower temperature and higher humidity will lengthen
the dry and cure times of primers.

All surfaces to be painted must be entirely free of dust, dirt, oil, grease, and other contaminants. Completely remove all loose, flaking, or chalking paint from the surfaces. Use a NIOSH approved respirator when sanding and when working
with old, loose paint particles. Provide adequate ventilation. Properly prime the clean, dry surface with a primer from our recommended list and allow the surface to dry completely—preferably overnight. Do not apply in temperatures below 50°F/10°C. Note: Lower temperatures and/or higher humidity will lengthen the dry
and cure times. Higher temperatures and/or lower humidity will speed up the dry and cure times.

Mix three (3) parts Colorfast EX Base (Component A) with one (1) part Activator CFEXU1000032 (Component B) by volume. Mix well (Hand Stir). No induction time required. Pot Life- 2-3 hours at 75° ± 5°F.

Colorfast EX can be brushed, rolled, or sprayed onto any paintable surface. Stir the paint thoroughly before using.

BRUSHING: Use a high-quality brush recommended for solvent or oil based paints. Usually, no reduction is required for brush or roll application.

ROLLING: Use a high-quality roller recommended for solvent or oil based paints. When rolling, work in approximately 4-foot wide sections, keeping a wet edge.

Depending upon the application environment, there may be times were the Brush & Roll Additive is needed to promote flow, leveling and air release for pre-mixed and activated Colorfast EX ZERO VOC Acrylic Polyurethane.

SPRAYING: Use an HVLP, Airless spray unit or an Air Assisted Airless spray unit. Use equipment manufacturer’s recommended tip sizes for solvent borne paint. Thin as needed—but carefully—as over thinning may result in loss of hide and a reduction of the desired appearance. Typically, 10-25% reduction with Colorfast EX Reducer will provide maximum atomization and flow characteristics. When spraying, use a properly-fitted NIOSH approved respirator
per the manufacturer’s instructions.

Clean brushes, rollers, tool, and equipment with compliant wash solvent immediately after use. Do not reuse containers and properly dispose of empty containers. As these products have a 2-3 hour pot-life, all application equipment, spray guns, pressure pots, etc. should be cleaned up immediately after use. Only activate enough material to be used within 2 hours of mixing.
