Physical properties were determined on specimens prepared under laboratory conditions using applicable ASTM procedures. Actual field conditions may vary and yield different results; therefore, data is subject to reasonable deviation.

Sauereisen VEMatte Reinforced System No. 470 is a multiple layer, 120-mil, fiberglass reinforced lining for chemical-resistant construction of sumps, dikes, containment areas, trenches, walls, and floors. This series of novolak vinyl ester linings offers superior resistance to mostinorganic acids, caustics, oxidizing solutions, solvents, and bleaches up to 250°F.

The VEMatte system includes VEPrime No. 550, VEMatte basecoat and topcoat No. 470, fiberglass reinforcement and
Saturant No. 471. A topping of VEGlaze No. 472 is used for aesthetics and ease of cleaning, if required. The Sauereisen VEMatte System is available in a modified vinyl ester formulation as the No. 420 Series.

CHARACTERISTICS

  • Resistant to most solvents, oils, acids and acid salts (except hydrofluoric) over a pH range of 0.0 to 14.0.
  • Maximum service temperature of 250°F (121°C).
  • Superior tensile/flexural strengths.
  • Fast chemical set; less down time.
  • Low porosity.

AREA PREPARATION

Temperature of Working Area
Maintain a temperature of 60°-85°F on air, substrate, Powder, Liquid, and Hardener components during mixing, application, and cure. The monolithic components and substrate should be maintained at 65°F to 85°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 made free of oil, grease, water, and other contaminants that may inhibit bond. This can be achieved by chemical cleaning.

Metal - Abrasive blast to a nominal 2.5 mil profile employing SSPC-SP10 Near White Metal Blast for immersion and SSPC-SP6 Commercial Blast for other service conditions. All welds must be continuous, free of flux and have a smooth rounded radius without any sharp edges.

Concrete - Concrete must be dry, firm, have attained 3000 psi compressive strength or be structurally sound as specified by the architect/engineer. Concrete should be floated free of ridges or depressions; all structural cracks must be repaired; voids filled, and slopes reestablished.

Abrasive blast or high-pressure water blast to remove laitance and obtain uniform sound substrate.

If chemical cleaning is utilized to remove contaminates, substrate must be neutralized. 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 profile, repeat surface preparation procedure.

APPLICATION

Mixing
With each component of the mat reinforced system; remix contents of Resin Part B component for a minimum of 2 minutes with a slow-speed paddle or "Jiffy" mixer. Add Hardener to resin and mix for a minimum of 2 minutes until thoroughly blended. For basecoat, mix resin and hardener for one minute. Gradually add powder while mixing continuously for 3 minutes.

Mix only complete batches. Material which has begun to set must be discarded. Do not try to retemper the material.

Installation
The VEMatte reinforced system is installed in five steps: Primer, VEMatte basecoat, Reinforcement, Saturant, and VEMatte topcoat. VEGlaze can be added as a smooth topping when desired. Installation steps are as follows:

Step one
Apply VEPrime No. 550 by roller to a thickness of 5-8 mils using a short nap roller with a non-degradable core. Allow primer to become tack-free for a minimum of six hours at 70°F before proceeding.

Step two
After mixing, trowel the VEMatte basecoat No. 470 to 1/16" (approx. 104 ft2 per unit) over the Primer.

Step three
Immediately press woven fiberglass matte reinforcement into VEMatte No. 470. Apply fiberglass cloth in a uniform
manner. Be careful not to wrinkle or intertwine material. Use 2" overlaps on the adjacent strips of cloth. Smooth matte reinforcement with a short nap mohair roller to eliminate air entrapment or pinholes.

Step four
After mixing, apply Saturant No. 471 by brush, roller, or spray until fiberglass becomes translucent (approx. 105 ft2 per unit). Allow installation to cure a minimum of 8 hours at 70°F before proceeding.

Step five
After Saturant No. 471 has cured, trowel another 1/16-inch thickness of VEMatte topcoat No. 470 onto the surface of applied system. Use a short nap mohair roller lightly moistened with acetone or MEK to provide a pinhole-free finish, eliminate voids, and remove trowel marks. Allow to cure at least 48 hours at 70°F prior to chemical exposure.

Step six (optional)
For applications where aesthetics or ease of cleaning is required, a topcoat of VEGlaze No. 472 can be applied. Contact Sauereisen for recommendations.
