Dura-Coat Krete-Seal 800
Technical Data Sheet
DESCRIPTION AND RECOMMENDED USES: 100% solids, Dura-Coat Krete-Seal 800 is a two component ambient- temperature curing epoxy coating. It is designed particularly as sealing and protection coating for concrete. Its low viscosity allows the Dura-Coat Krete-Seal 800 to flow easily, sealing cracks and filling pits. Dura-Coat Krete-Seal 800 is convenient-to-use, non-sagging easily applied by brush, roll and spray. It is an excellent primer for using with Dura-Coat concrete top coats.
- It is usually applied with 8-10 mils
- Prevent vapors to rise from substrate
- Suitable for priming concrete with topcoat
- Suitable for immersion and non-immersion service
Application Areas
- Secondary containment
- Chemical tanks
- Concrete walls
- Sumps
- Pump base
- Concrete channels
- Drains
- Chemical processing floors
- Pits
- Neutralization tanks
- Equipment bases

Application Sheet
Surface Preparation
Proper surface preparation is critically important for the long-term performance of the Dura-Coat Krete-Seal 800. The prepared concrete surface must be structurally sound, free from all contaminants and roughened to an >ICRI CSP 3 profile (similar to #60 grit sandpaper). If a vapor barrier is not present, check for vapor transmission.
Surface Cleaning & Profiling Methods
Hydro-Blasting Scarifying
Steel Shot-Blasting Dry Abrasive Blasting
Mixing
Thoroughly mix Activator into Base with mixing stick or drill with low speed mixing blade scraping sides and bottom of container or mixing board. Mix by weight 1.9-part Base to 1-part Activator. Mix thoroughly to produce an even colored and streak-free material. THINNING: Never thin.
Application
Application temperature range 10°C (50°F)-32°C (90°F) (substrate).
Dura-Coat Krete-Seal 800 may be applied by spray system, brush, or roller.
Brush: medium to stiff bristle of sufficient quality that bristles do not pull out and stick in coating (epoxy glued bristles are best). Trim or tape to <1” nap.
Roller: use good quality 1/8” nap.
To avoid sagging on vertical surfaces the maximum wet film thickness should be between 200 μm-250 μm (8-10 mil) per coat
