NovolaK VEGlaze No. 472 is specifically formulated to accommodate vertical and overhead applications. No. 472 can be applied by roller or spray as an economical option to protect concrete and steel in the power, petrochemical and pulp & paper industries.
- Characteristics
- NovolaK Vinyl ester polymer offers superior chemical resistance.
- Spray or roller application.
- Fast chemical set - less down time.
- Easily cleaned surface.
- Low porosity.
- High Temperature resistant for flue gas applications.

- Cure Method
- Area Preparation
Temperature of Working Area
- Maintain a temperature of 60°-85°F on air, substrate, Hardener and Resin components during mixing, application, and cure. The materials and substrate should be maintained at 65°F to 80°F for 48 hours prior to beginning work.
- At temperatures below 60°F, the application becomes more difficult and curing is retarded.
- Above 85°F, the material working time decreases. It is recommended that the material components be stored in a cooler area prior to mixing. Shading the substrate and using ice water to cool mixing equipment is not uncommon. In extreme temperatures it may be necessary to postpone the application or to apply during cooler hours.
Surface Preparation
- Surfaces should be dry and made free of oil, grease and other contaminants that may inhibit bond. This can be achieved by chemical cleaning.
- New Concrete - Abrasive blast, high-pressure water blast, or acid etch concrete to remove laitance and obtain uniform surface texture.
- Old Concrete - Concrete must be dry, firm and structurally sound as specified by the architect/engineer. All structural cracks must be repaired. Abrasive blast, high-pressure water blast, or acid etch concrete to remove laitance and to obtain a uniform, sound substrate.
- If abrasive or high-pressure water blasting is used as the method of surface preparation, all sand and/or debris must be removed by thoroughly vacuuming the area with an industrial vacuum cleaner. If surface does not have desired characteristics, repeat surface preparation procedure.
- Metal - Abrasive blast to a nominal 2.5 mil profile employing SSPC-SP5 White Metal Blast for immersion and SSPC-SP10 for other service conditions. All welds must be continuous, free of flux and have a smooth rounded radius without any sharp edges or protrusions.
- Application
Mixing
- VEPrime No. 550 and NovolaK VEGlaze No. 472 are each packaged in premeasured containers consisting of Hardener Part A and Resin Part B which must be mixed together before use. Individual components should be remixed before combining. The following procedures are applicable to the mixing of both products.
- Completely empty contents of Hardener Part A into Resin Part B container. Using a slow-speed drill motor with a "Jiffy" type blade, mix for a minimum of three minutes until thoroughly blended.
- Mix only complete batches. Material which has begun to set must be discarded. Do not try to retemper the material.

Technical Details & Test Data
- Coverage
- VEPrime No. 550
- 260 ft² per one gallon unit at 6 mils wet film thickness, resulting in a dry thickness of approximately 5 mils.
- VEGlaze No. 472
- 160 ft² per gallon at 10 mils wet film thickness, resulting in a dry thickness of approximately 6 mils.
All coverage data is theoretical and will vary depending upon surface conditions, porosity, application techniques and project specific conditions.
- VEPrime No. 550
- Setting/Curing
- VEPrime No. 550 may be topcoated after twelve (12) hours at 70°F. If the duration before topcoating exceeds 24 hours, consult Sauereisen for proper solvent wipe procedures.
- NovolaK VEGlaze No. 472 will take an initial set in two hours at 70°F. Do not allow water or chemicals on the material surface for a minimum of 24 hours. For temperatures below 70°F, cure a minimum of 72 hours prior to water or chemical exposure.
Safety & Health
- Clean-Up
All equipment should be cleaned by scrubbing with a stiff brush and MEK or MCT (monochlorotoluene) at the end of each working period or when build-up becomes pronounced.
