- Surface Preparation
- A successful application for a durable and beautiful floor will be the result of a thoroughly prepared substrate. This is time well spent and crucial in achieving a long-lasting floor.
- New concrete should be allowed to cure a minimum of 28 days. For concrete brick, the mortar must also be allowed to cfor ure 28 days.
- Moisture present on or in the concrete will compromise the floor coating.
- Bare concrete should be tested for pH and have a level between 7 and 11 by using a pH test kit. Refer to ASTM F-710, (“Standard Practice for Preparing Concrete Floor to Receive Resilient Flooring”) for further information on pH testing.
- Testing for moisture may be done with the following tests. ASTM D-4263 (Plastic Sheet Test) Using 2” Duct Tape, secure an 18”x18” sheet of transparent polyethylene to the slab, sealing it completely. Leave for at least 24 hours. Moisture under the plastic will indicate excessive moisture in concrete and a requirement for further testing.
- ASTM F1869 (Standard Method for Measuring Moisture Vapor Emission Rate of Concrete Sub Floor using Anhydrous Calcium Chloride Moisture Emissions Test) can be used to determine the rate of moisture emission. A small dish of calcium chloride is weighed and placed under a plastic cover for 24 hours. The dish is removed and weighed again. The amount of water gained in the water vapor moisture will then determine the emission rate of the concrete. Moisture vapor transmission rate should not exceed 3 lbs. per 1000 sq. ft. in 24 hours as tested.
- ICRI (International Concrete Repair Institute) Guide 03732 (Selecting and Specifying Concrete Preparation for Sealers, Coatings, and Polymer Overlays) can be used to determine the suitability of the concrete for this floor system.
- Do not apply when the relative humidity of the concrete is greater than 75% as tested to the ASTM F2170-02 (Standard Test Method for Determining Relative Humidity in Concrete Floor Slabs Using In Situ Probes).
- The concrete must be structurally sound and free of all and dirt, oil, grease, curing compounds, form release chemicals, coatings, andbeforetaminants before any abrasive blasting. Wis oil or grease are present, and successful penetration and adhesion of the PRECIDIUM™ LS1150D will be at risk.
- A simple test for grease that may not be visible is to mist water on the surface of the concrete. If the water beads up, contaminants are present and must be removed. If the water is absorbed into the concrete surface, oils are not present.
- If any contaminants are present, the use of proper detergents may be required. Standards for cleaning concrete are available in SSPC (Society for Protective Coatings) SP-13.
- Do not apply the PRECIDIUM™ LS1150D when the temperature of the concrete substrate exceeds the surrounding air temperature by more than 10°C; 18° F, due to outgassing. The porosity in concrete contains air. When the temperature of the concrete rises, the air in the pores expands, causing blisters or pinholes in the coating. An increasing surface temperature is a strong indication that outgassing will occur.
- Keeping the concrete slab and ambient temperature within the stated range is essential as outgassing is further aggravated when abrasive blasting or scarifying breaks the thin concrete crust, thus opening more air pockets and bug holes. Concrete is very dynamic. It crackbreaths, shrinks, moves,s, breaths, absorbs water and honors water vapor. By honoring the dynamics of concrete when applying this floor system, the best possible outcome is achieved.
- Abrasive shot blasting or grinding of cobeforeurfaces is reapplied to the coating application to provide a suitable surface texture for proper adhesion. A visual standard for an acceptable concrete profile is available in ICRI CSP 2-4.
- If repair and crack filling is required, the use of PRECIDIUM™ 2100 would be used. Follow mixing and application instructions on the product’s technical data sheet. Before using any alternative concrete repairs, consult Quantum Chemical for compatibility.
- Using or combining any other products with the PRECIDIUM™ LS1150D without prior written approval from the manufacturer will void the defective product warranty.
- Product Application
Product Mixing
PRECIDIUM™ LS1150D is a two-component system mixed 1:1, Resin:Iso. Thoroughly mix the resin component prior to combining it with ISO. Using graduated plastic mix containers, combine equal parts, by volume, of Resin and Iso. Thoroughly mix Resin and Iso with a low-speed drill and mixing attachment, taking no longer than 1.5 minutes and being careful not to incorporate any air into the mixture.
Mix only the amount of material that can be applied within 10 minutes. On average, a ten-minute batch of PRECIDIUM™ LS1150D is 1 - 3 quarts of mixed material. Pour ribbons of PRECIDIUM™ LS1150D over the application area. The above amount will be enough material to pour out 2 - 4 ribbons.
Equipment
When applying the PRECIDIUM™ LS1150D, proper equipment is essential. The standard application tool for applying the primer coat, base coat, and final clear top coats, will be a high-quality 18” epoxy roller cover with an adjustable 9 - 18 ” roller cage.
Accents - For the decorative accents, applicators must be properly trained on the application techniques required to achieve the various decorative finishes. Spiked shoes will be required to apply this multilayered floor system.
Do not use a roller tray. Ribbons can be squeegeed over the area and back-rolled with an epoxy roller sleeve. During the project the roller should be rolled dry every 100 - 300 sq. ft. This will prevent the roller from becoming tacky and will increase its life of the roller. After the initial roll, it is important to back-roll the floor. Back-rolling is done to ensure even application and will help with breaking any balloons that may have formed from filling pinholes. On average a roller cover will do 500 - 1000 sq. ft. before replacement.
RSF Layers
When PRECIDIUM™ LS1150D floor coating is used as a layered system, the optimum mil thickness of each layer will vary from 3 - 10 mils depending on project specifics and the layer being applied. Individual technical data sheets with detailed application instructions are available from Quantum Chemical for each component of the layered system.
- Primers - The PRECIDIUM™ 2100 is excellent for repairs, leveling and crack finishes but the modified PRECIDIUM™ 2200 Primer is an excellent primer as it has a lower viscosity and therefore better penetration into the concrete. It adds a degree of impact resistance and has excellent adhesion but is not recommended for floors that would come into contact with harsh solvents and chemicals. The PRECIDIUM™ LS1150D is also often used as the primer on properly prepared concrete. Based on the preparation (shot blasted or diamond ground) it would typically be thinned with 10% Xylene to increase penetration into the concrete. The thickness would be ~3 - 4 mils. Once tack-free (1 - 3 hours), the color base coat would be applied. For concrete that isn’t shot blasted or ground, discuss the suitability of this floor system with the manufacturer.
- Color Base Coat - Apply the PRECIDIUM™ LS1150D color base coat at ~4 - 7 mils. Again this could vary depending on whether this will be a cast coat for broadcast media or the base color coat for the accent system. For accent colors allow the 5 - 7 mil color base coat to cure until tack-free (1 - 3 hours depending on temperature and humidity).
- PRECIDIUM™ PUD Accents - Contact the distributor or manufacturer for proper application equipment for the desired finish. This one-component system has unlimited pot life. Excess materials can be returned to the containers for future use. For accent colors, the first accent is applied once the surface is tack free. Due to the relatively short cure-time, additional accent colors can typically be applied within 10 - 30 minutes. One to three accents are typically applied.
- Color Base Coat And Broadcast Media - When using color chips or quartz the first color coat would be applied at 3 - 4 mils. Once tack-free, apply a second coat at 2-3 mils and immediately apply color chips or quartz to the surface. Allow the surface to cure for approximately 3 - 4 hours. Remove excess chips or aggregate with a stiff brush.
- Clear And Clear Non-skid Top Coats - The final clear coat(s) will vary depending on the floor system. A chipped floor may require ~10 mils or more of clear coat to ensure zero exposure of chips while leaving enough texture to provide a suitable coefficient of friction. When accent colors are used, a clear coat of ~3 - 4 mils would be applied followed by a final clear coat non-skid coat of ~2 - 3 mils. This is a guide only and must be carefully reviewed for appropriateness for a project and adjusted accordingly to comply with project-specific requirements as determined by the qualified applicator during the initial site visit.
Allow the finished system to cure 24 hours before being put into service, however, the longer the floor can be cured or at least protected, will improve the overall success of this floor system.
- Clean Up
Clean tools and application equipment immediately after use with solvent such as MEK, Xylene or Acetone. Clean spills or drips immediately with solvent. Cured PRECIDIUM™ LS1150D must be mechanically abraded for removal. Do not use alcohol or lacquer thinner blends that contain alcohol to clean equipment or tools.

- Limitations
- Lower temperatures and humidity will slow cure time.
- Do not install over a grade concrete slab unless a moisture barrier has been placed under the slab.
- PRECIDIUM™ LS1150D is not recommended for pool applications.
- Maintenance & Care
The PRECIDIUM™ LS1150D is easier to clean because it is seamless and also non-porous so dirt and debris remain on the surface. It also has a high chemical resistance with superior performance over many other types of flooring.
- Clean the PRECIDIUM™ LS1150D regularly to remove all dirt, stains and debris as these do remain on the surface of the floor and damage the finish in heavy traffic environments.
- Do not use soap because it will create a film that is difficult to remove with rinsing. This film will become slippery when wet, plus it attracts dirt and debris, causing the floor to look dirty much sooner.
- Floor stripping agents, citrus-based cleaners and corrosive chemical degreasers not recommended as they damage the floor if they are applied and remain on the floor for an extended period of time.
- A simple mixture of a pH neutral cleaner, diluted with water, is recommended for regularly scheduled cleaning.
- Thoroughly clean the soiled area with a synthetic mop, scrubbing stains with a soft-bristled brush. Cotton mops will catch on chips, quartz and the more aggressive non-skid additives.
- If a cleaning chemical is required, use a commercially available alkaline cleaner or degreaser.
- Thoroughly rinse the cleaned area to remove remaining dirt and cleaning agents.
- Use a foam squeegee to remove excess water.
- Allow the surface to dry before returning to service.
- Contact the manufacturer for removal of stains that are resistant to the above cleaning instructions.
