PERMATEC 4000 is a 100% solids, modified epoxy floor topping. The PERMATEC 4000 system consists of a two component resin binder and graded aggregate. It is applied with a trowel or screed rake at 1/8-1/4 inches (125-250 mils) in a one coat application including a silica broadcast. There is no need for a primer or sealer coat. An optional glaze coat may be used to improve the appearance and cleanability.
The vertical formulation of PERMATEC 4000 is trowel applied at 1/8 inches (125 mils).
The primary use of PERMATEC 4000 is as a high strength floor topping for industrial service where severe mechanical abuse and/or chemical exposure is anticipated.
- Process floors
- Containment basins
- Any area in general where harsh chemicals are used
PERMATEC 4000 is a 100% solids system and allows for a fast application where good chemical and wear resistance are required. PERMATEC 4000 can be installed over most sound floors including old or new concrete and most types of repair mortars. At varying thickness up to 1/4 inches, the PERMATEC 4000 system provides long term chemical resistance for splash and spill, or immersion service in many chemicals.
PERMATEC 4000 is similar to PERMATEC 3000 but provides a higher degree of chemical resistance to concentrated acids, caustics and solvents. As with all PERMATEC systems, PERMATEC 4000 provides excellent physical protection even in the harshest industrial settings.
Other Features Include:
- Rapid cure resulting in minimal downtime
- 100% nonporous
- Can be applied over damp concrete
- Nonskid safety finish

Packaging & Coverage
PERMATEC 4000 is available in 20, 100, and 1000 square foot units based on 1/4 inch applications. Each unit consists of pre-measured components. Part A (Resin) and Part B (Hardener). Graded aggregates are available or may be sourced locally.
Application thickness may vary from 1/8 to 1/4 inches, depending on the expected service conditions. Factors to consider are 1) length of chemical exposure (e.g. immersion vs. splash/spill) and; 2) mechanical abuses (e.g., tow traffic, loaded trucks vs cart and foot traffic, etc.)
Note: Some applications may not require a 1/8 or 1/4 inch floor topping (e.g. secondary containment, many vertical applications, etc.)
The cure time of PERMATEC 4000 and other resinous systems are very dependent upon the temperature of the substrate. The ambient temperature may not be the same as the substrate temperature. For example during winter, concrete may be colder than the surrounding ambient temperature. As temperatures during the day may increase, large masses of concrete will be much slower to react. During summer days direct sunlight will increase the concrete temperature over that of the ambient air. The substrate temperature should be monitored and remain at or above 65°F.
*Where heavy chemical abuses are anticipated, longer cure times may be required.
Mixing & Application
The following is a brief summary of concrete preparation and the application procedure for PERMATEC 4000. This information is intended for use in the system evaluation.
New Concrete– The concrete should be well cured for a minimum of 10 days per ACI 308-81, (R-1986) clean, dust free and free of all contaminants. Mechanical methods such as sandblasting, scarifying, or shot blasting should be employed to remove the weak layer of surface laitance. A minimum tensile strength of 200 psi is required of the prepared surface. Acid etching with muriatic acid is acceptable but less desirable. Care must be taken to completely remove all residual acid prior to the application of PERMATEC 4000.
Existing Concrete- Concrete must be structurally sound and free of all contaminants. Weak or contaminated concrete must be removed until sound concrete is realized. Old coatings, toppings, waxes, oils, etc. must be removed prior to application of PERMATEC 4000.
Prior to application, the PERMATEC 4000 (Resin, Hardener, and Silica) and the substrate should be between 65°F and 90°F.
In order to maintain a clean mixer from batch to batch, the Resin (Part A) and a portion of the Silica (Part C) should be added to the mixer and agitated long enough to clean the blades. Add the Hardener (Part B) only when the batch is ready to be applied. Mix for approx. 30 seconds-1 minute, then add the remainder of the silica and mix for another 90 seconds. Pour immediately onto the floor.
A self-leveling tendency will be noticed after the material has been poured on the surface to be coated, however some assistance is required in order to achieve the specified thickness. Conventional hand-trowling and screed raking are the two recommended methods of application. Screed raking is generally preferred because of the uniformity in thickness that can be achieved. A silica broadcast is required for proper filling of the system and for skid resistance. The surface should be saturated and the excess removed after the material has set.
PERMATEC 4000 contains blended epoxies as the resin and blended Amines as the hardener. Protective clothing and gloves are recommended to prevent sensitization to these materials. In case of ingestion or eye contact contact a physician immediately. MSDS are available for this product upon request.
All mixing and application equipment should be cleaned immediately after use. If this is done, soap and water, or biodegradable cleaners can be used. If the material has begun to set, more aggressive solvents will be necessary.
Storage & Shelf Life
PERMATEC 4000 should be stored at 50-90°F out of direct sunlight. All containers should remain unopened until ready for use. If stored as set out above PERMATEC 4000 has a minimum shelf life of one year.
Where PERMATEC 4000 Should Not Be Installed
PERMATEC 4000 should not be applied over substrates:
- subject to hydrostatic pressure
- which are unsound
- which are contaminated and cannot be cleaned
- at temperatures below 65°F
