Sauereisen ConoSpread™ - VE NovolaK 450 is a versatile vinylester flooring system designed for standard pour & spread application methods.

This product offers excellent application properties and diverse chemical resistance. Typical installations involve the application of a basecoat slurry that is topped with a broadcast for additional skid resistance. Sealing of the broadcast is required to ensure proper cure. Sauereisen VEGlaze 472 may be used for the sealer coat.

ConoSpread™ 450 is packaged as a unit to facilitate project needs. Refer to the estimating table for coverage of the system.

ConoSpread™ is commonly specified as protective flooring for process areas in the food & beverage, chemical processing, pharmaceutical, steel, mining, power, and metal finishing industries. The ConoSpread™ system should be used with an appropriate Sauereisen primer to enhance bonding. Consult Sauereisen for a primer recommendation depending on the type of substrate and surface conditions.


  • Excellent thermal shock resistance.
  • Resistant to a wide range of acids, alkalies and some solvents.
  • Special formula available for fluoride environments.
  • Available colors: 53 gray, 01 black.


Temperature of Working Area
The monolithic components and substrate should be maintained at 65°F to 85°F for 48 hours prior to beginning work.

For optimum conditions, maintain a temperature of 65°-85°F on air, concrete substrate and material components during mixing, application, and cure.

At temperatures below 65°F, the application becomes more difficult and curing is prolonged. Above 85°F, the material working time decreases.

Application in direct sunlight and rising surface temperatures may result in blistering of materials due to expansion of entrapped air or moisture in the substrate. Concrete that has been in direct sunlight must be shaded 24 hours prior to application and remain shaded until after the initial set. In rising temperatures, it may be necessary to postpone the application or to apply during cooler hours.

Surface Preparation
Refer to SSPC-SP13/NACE 6 "Surface Preparation of Concrete" for detailed guidelines.

All concrete must be dry, firm and structurally sound as specified by the architect/engineer. Concrete shall have a
tensile pull-off strength of 200 psi or greate. Abrasive blast, high-pressure water blast, or acid etch concrete to remove laitance and to obtain uniform surface texture resembling coarse sandpaper.

All sand and/or debris must be removed by thoroughly vacuuming the area with an industrial vacuum cleaner.

If surface does not have desired texture, repeat surface preparation procedure.

New Concrete - Concrete should be floated free of ridges or depressions and all voids filled with Sauereisen Underlayment F-120 or Filler Compound 209, depending on the severity of the voids. Concrete should be sloped a maximum 1/8 inch per foot for drainage. Too much slope may result in inconsistent coverage or require a stiffer mix. Consult Sauereisen for recommendations.

Sauereisen considers acid etching to be the least preferred method of surface preparation, but it remains an option when carefully controlled. Refer to ASTM D-4260 "Standard Practice for Acid Etching Concrete" for the appropriate procedure. All acid and residue must be removed prior to placing the ConoSpread™ system. In addition, the surface must be thoroughly dry before applying the primer or slurry.

Old Concrete - All structural cracks must be repaired and slopes reestablished with Sauereisen Underlayment F-120. Finished substrate should be sloped to a maximum 1/8 inch per foot.

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 texture, repeat surface preparation procedure. Afterward, the application should not ensue until the surface is dry.


Joints are to be provided on 14-foot centerlines and over existing expansion/control joints. Joints should also be placed around all fixed objects, peripheries of rooms and all points of movement in the base slab. Consult Sauereisen for recommendations.


Primers - An appropriate Sauereisen primer should be applied prior to the vinyl ester flooring installation. VEPrime™ 550 or Hi-Temp Primer 560 may be used depending on the conditions of the substrate. Review the primer data sheets for mixing, curing, and application instructions.

Mixing of ConoSpread - GENERAL - When using ConoSpread™, empty contents of Part A Catalyst, Part B Resin and Part D Pigment into clean container and mix thoroughly with a drill motor and "Jiffy" blade for at least 3 minutes. Immediately pour entire contents onto floor and spread with a trowel, roller, or screed rake to the specified thickness.

Mixing of ConoSpread™ – UNFILLED SYSTEM - When using ConoSpread™ as an unfilled coating or sealer, mix as above and add one unit of Gel Coat Additive to the resin.

Slurry mixes - When using 450 as a slurry, empty Parts A, B, D, as above into a clean mixing vessel and mix for at least two minutes.

Add Aggregate Part C to obtain the desired consistency. Aggregate loading rates will vary depending on the thickness specified.

Regular Unit 135 sw. ft 1 pt. (0.73 lbs.) 5-gal. (35 lbs.) 3 bgs (150 lbs.) 1 pt. (0.4 lbs.)

Installation of Basecoat Slurry – Pour the material in a narrow band starting at any convenient wall or joint. Spread using a screed rake or cam rake. After the material has been spread, backroll using a 1/4 inch short nap roller and spiked roller. Workers should wear spiked shoes to allow the slurry to selflevel.

When building towards a total system thickness of 1/4 inch, distribution of the basecoat slurry may be by assisted with a trowel.

Broadcast Procedure – Immediately after backrolling, additional Aggregate should be broadcast into the slurry to thicken the basecoat and/or provide skid resistance.

For a uniform surface texture, Aggregate should be broadcast to rejection. For fluoride resistance, alternate aggregates may be required. Please consult Sauereisen.

Sealing Procedure - The final step of a sealer coat is required. Left unsealed, the basecoat may not cure properly. Sealing may be done with either an unfilled gelcoat (consisting of 450 components A, B, and D) or with a topcoat of Sauereisen VEGlaze 472.

Sauereisen recommends either VEPrime™ 550 or Hi-Temp Primer 560 to enhance the bond of vinylester ConoSpread. Allow the appropriate primer to cure in accordance with its data sheet prior to applying ConoSpread™. The maximum cure time for primers prior to the ConoSpread™ application is 24 hours.
