Sauereisen Vinyl Ester Mortar 400 is used in the construction of floors, sumps, trenches, tanks, vessels and bleach towers in chemical processing; food & beverage plants; dairies; laboratories; textile, steel and pulp & paper mills. 400 has excellent resistance to oxidizing bleach solutions, mineral and organic acids, alkaline solutions and some organic solvents. When used with chemical-resistant masonry units and the proper membrane, 400 will protect concrete and steel substrates from chemical attack and physical abuse. 400 is a silica-filled vinyl ester mortar supplied in two parts - Powder and Liquid - which must be mixed together in the proper proportions prior to use.

Sauereisen Vinyl Ester Mortar 400 meets standards of the USDA for use in federally inspected meat and poultry plants.


  • Resistant to strong oxidizing agents, acids, alkalies and bleaches through 250°F (121°C).
  • Low absorption and shrinkage.
  • High bond, tensile and compressive strengths.
  • Rapidly develops physical properties ...initial set time is one hour 70°F.


Temperature of Working Area
Maintain a temperature of 60° - 80°F on air, substrate, 400 Powder, 400 Liquid, and masonry units during mixing, application, and cure. Maintain materials and substrate between 70°F - 80°F for 48 hours prior to beginning work.

At temperatures below 60°F, the viscosity increases, application becomes more difficult and curing is retarded. When using 400 at temperatures between 50°-60°F, 400A Accelerator can be added to the Liquid to hasten the cure of the mortar. Consult Sauereisen for specific recommendations. Above 80°F, working time of the material decreases. In higher temperatures it is recommended that the Liquid be cooled by placing the pail in a large container filled with water and ice or storing in a cool area.

Surface Preparation
All surfaces in contact with 400 must be clean, dry, and free of dust, dirt, grease, oil, and other contaminants. Surface prep should be in accordance with membrane requirements.


Empty correct proportion of Liquid into a clean mixing vessel. Gradually add measured amount of Powder while mixing continuously with a trowel, hoe or mechanical mixer until mortar is uniformly blended to a workable consistency. After mixing, spread mortar in a thin layer onto a mortar pan to ensure the maximum working time of 25 minutes at 70°F.

The recommended mix ratio, parts by weight, is as follows:
Powder Liquid
3.25 1

For application in colder environments, 400A Low Temperature Accelerator may be added to assist workability and cure as needed.

Material which has begun to set cannot be retempered and must be discarded. Never add Liquid or other materials to mixed material or any component part.

Trowel an average 1/8-inch thick bed joint of No. 400 directly on top of membrane or preceding course of brickwork. Apply the mortar by buttering on side and one head joint of each masonry unit. Set the masonry units in place and position by tapping to form an average 1/8-inch wide vertical joint.


Strike extruded mortar off the face of the masonry unit with a trowel. For floors where appearance is a factor, waxed face units are recommended.

When waxed units are used, wait until 400 Mortar has achieved full cure (24 hours at 70°F) and clean face of masonry units using 60 psi (minimum) steam pressure at the nozzle.


All equipment should be cleaned with acetone or MEK before 400 cures. If removal is required after cure, consult Sauereisen for recommendations.


400 is self-hardening due to a chemical reaction which occurs when the Powder and Liquid are mixed together. An initial set occurs in one hour at 70°F.The material is ready for service after 24 hours at 70°F.

Brickwork should not be subjected to water, steam or chemical environment before the mortar is completely cured.

The above quantity requirements are based upon physical dimensions of chemical-resistant masonry units and actual weight of mortar as determined by ASTM C-905. Actual usage rate will vary dependent upon scope of installation, experience of workmen, field conditions and other contingencies. Personnel using the above chart should, therefore, add an appropriate wastage factor.


Joints are to be provided on 20-foot centerlines, around all fixed objects, peripheries of rooms and all points of movement in the base slab. Consult Sauereisen for product recommendations.


400 Liquid: 30 lbs. in a 5-gal pail.
400 Powder: 100 lbs. in 2 plastic-lined 6-gal pail, 50 lbs each.
400A: 2 ounce bottle.


Sauereisen Vinyl Ester Mortar 400 should be stored in unopened, tightly sealed containers in a dry location at 70°F. Avoid freezing.

Under these conditions, the 400 Powder has a shelf life of six months, 400 Liquid has a shelf life of four months and the 400A Low Temperature Accelerator has a shelf life of one year. If there is a doubt as to the quality of the materials, consult a Sauereisen representative.
