- Uses
Arctic Cap HV is designed to protect and seal a variety of roof systems and can be used as either a base or surface coating. When the substrate is properly prepared, Arctic Cap HV can be used on BUR and granulated modified bitumen membranes; this product is also approved over most metal roof systems and PVC single ply. Arctic Cap HV can be applied to concrete and most rigid cover boards. Usage to certain substrates may be limited or require additional preparation.
- Application Instructions
Surface Preparation:
- All surfaces to receive coating must be clean, dry and free from any foreign matter such as dirt, oils, grease or other debris that could inhibit the adhesion capabilities of the newly installed products.
- Metal surfaces that display rusting or other oxidation, to be prepared with a grinder or wire brush as needed to remove surface contaminants.
- Existing roof systems to be visually inspected for conditions that may adversely affect adhesion of performance of newly installed products.
- Visually inspect all metal and non-metal flashings, edges, drains, valleys and through-roof penetrations and repair as needed by project conditions.
- Do not apply to wet or visibly damp surfaces, or surfaces previously covered with coal tar based products or Kynar® finishes.
- Concrete surfaces cured with wax/resin based compounds can inhibit adhesion.
Application:
- Mix well prior to application.
- Arctic Cap HV is recommended to be applied with high pressure sprayer for best appearance and coverage, however may be applied by roller or brush applications.
- Apply Arctic Cap HV at 24 wet mils (1.5 gallons per 100 square feet) per coat. Typical application conditions require Arctic Cap HV be applied in two coats at 24 wet mils per coat.
- Allow coating to dry overnight prior to applying second coat.
- To minimize potential voids or pinholes in coating application, apply second coat perpendicular to the first.
- Apply only when ambient temperatures are 50°F and rising. Cold weather could result in uneven application and improper curing of product. Do not apply if there is a threat of inclement weather within 24 hours of application.
- Do not thin product. Do not heat outside of container. Do not apply at temperatures greater than 120°F.
- Prior to using this product on new cap sheets (smooth or granulated), it is recommended to wait 30 days for weathering.
- Spray Equipment
Arctic Cap HV can be applied by conventional airless spray equipment designed for the purposes of field application of fluids, paints and coatings. The following minimums are recommended:
Pump: 1 gal/min output; 2,000 psi
Gun/Tip: Airless hand gun with 30 mesh screen. Reversible tip with orifice sizes ranging from .027–.039 and a fan angle of 40° or 50°.
Hose: Minimum inside diameter of high pressure nylon hose of 3⁄8" to 75'; 1⁄2" to 200'.
Refer to equipment manufacturer product guidelines.
