ReflectASeal 405


REFLECTASEAL-405 is a flexible two-part epoxy designed to protect a variety of vertical and horizontal surfaces, including stucco, concrete, cinder block, brick, stone, wood, and others. It is especially suited to applications where surface movement may defeat the protection of a rigid coating.

Advantages & Benefits
Designed for vertical and horizontal application.
Adheres to damp surfaces without priming.
Stays flexible through years of harsh service.
Withstands attacks from most chemicals, and severe environments.
Retains flexibility in sub zero conditions.
Rain will not destroy coating during application.
Provides a secure barrier to water penetration. 


Surfaces must be cleaned free of grease, oil, films, dust, or any other contaminants. Most surfaces should be pressure washed to remove any barrier films. Hard-finished concrete should be etched to provide profile or “tooth” for optimal adhesion. These preparation procedures are general guidelines. Consult REFLECTASEAL technicians for further details or special preparation procedures. The preparation procedures above are general guidelines. Detailed preparation methods are available through SSPC at or 412-281-2331 or NACE at or 281-228-6200.

The mixing of parts A & B is very important! REFLECTASEAL-405 has a mixing ratio of 2 parts “B” to 1 part “A”. Agitate each part separately before combining the two. Use a power mixer to thoroughly combine both parts. Mix for at least 1 minute per gallon. Allow idle activation time for at least 10 minutes. Lacquer Thinner should only be added after the activation process is complete.

REFLECTASEAL-405 can be applied by air-less spray equipment, brush, or roller at approximately 200-sq. ft. per gallon. A two-coat application is recommended to help insure complete protection. Surfaces subject to significant movement or other difficult conditions may require heavier applications. Surface configuration, weather, or area surroundings may dictate application method.

Dry Film Application Rate:
To yield dry film of Apply Sq. Ft/gallon
12.5 mils: 100 Sq. Ft.
6.25 mils: 200 Sq. Ft.

DO NOT apply product heavier than 8 wet mils per coat. If more is needed, apply in multiple coats. Allow REFLECTASEAL-405 to become tack-free before applying additional coats or approximately 5 hrs at 80ºF.

If thinning is necessary, thin no more than 3/4 pint of lacquer thinner per gallon of epoxy. Lacquer thinner should only be added after idol activation process is complete. Thinning retards cure time and may cause sag.


REFLECTASEAL-405 should be applied in well-ventilated areas. Surfaces should be free of foreign matter. DO NOT apply near an open flame.


Clean Up:
Application equipment should be cleaned immediately with lacquer thinner. Use Apple Cider Vinegar to clean hands and skin. Do not allow coating to remain on tools! Once it sets and is cured, it is difficult to remove.


Flammable during application
Will not support combustion when cured
