Apply with a soft brush (avoid excessive brushing), roller or airless spray. Allow Kool Seal® RV Rubber Roof Primer to dry 24 hours prior to applying any Kool Seal® Elastomeric topcoat. This product has excellent suspension and requires
minimal stirring. DO NOT THIN.

Airless Spray:
• Pressure: 3,300 psi
• Spray tip: Reversible, self-cleaning tip
without diffuser pin. Size .031" with a fan
angle of 60° (ex. 631).
• Hose Size: At 300’ total hose length,
use 250’ of ¾”- ½”
10’ swivel whip end 3/8" hose.
• General: The longer the hose, the
smaller the tip orifice size.

• Soft brushes or a ¾” nap roller may be
used. May require multiple coats to
achieve proper coverage.

Once the surface has been properly prepared coat the entire roof with Kool Seal® RV Rubber Roof Primer. Do not apply the primer when the temperature is below 50° F or if the temperature is expected to drop below 50° F before the coating has completely dried.

NOTE: In areas where dew accumulates in the early evening it is best to stop coating by
3 P.M. to prevent wash off which will occur if dew, fog, or rain arrive before the coating dries. Allow 4 - 6 hours for coating to dry prior to being subjected to rain,
heavy dew or temperatures below 50° F.
