1100 - Clear Series




NO. 370

1100-CLEAR Series

Provides an impermeable film which optimizes moisture retention.

SEALTIGHT 1100-CLEAR Series Resin-Base Water-Base Concrete Curing Compounds are ready-to-use, true water-base compounds formulated for full VOC compliance.

Technical Description
The SEALTIGHT 1100-CLEAR Series Water-Base Concrete Curing Compounds are formulated from hydrocarbon resins and may be used on interior, exterior, vertical and horizontal concrete surfaces. Once applied, they form a liquid membrane that retains an optimum amount of water present in freshly placed concrete to allow complete hydration of the cement.

NOTE: After approximately 4 weeks, the membrane begins to chemically break down. When the curing cycle is complete, the membrane will eventually wear off the surface. This process usually takes another 3 to 5 weeks under normal traffic and weathering conditions.

The 1100-CLEAR Series meets maximum Volatile Organic Compound (VOC) content of 350 g/L for Concrete Curing Compounds as required by the U.S. EPA Architectural Coatings Rule. SEALTIGHT 1100-CLEAR Series has a substantially lower VOC content than the 350 g/L required in the above noted rules.

The 1100-CLEAR Series has been used on both interior and exterior applications where paint, resilient tile or resilient flooring was applied later. Because of the wide variety of paints and adhesives for carpeting and resilient tile in use, contact the manufacturer of the flooring system for application approval over resin-type curing compounds. A small test application is also recommended.

Advantages and Benefits

bulletWhen properly applied, they produce an impermeable film which optimizes water retention
bulletFurnished as ready-to-use, true water-base compounds
bulletProduce hard, dense concrete...minimize hair-checking, thermal cracking, dusting and other defects
bulletEnhance the functional capabilities of concrete by "sealing in" the performance assets of strength and long life
bulletOffer a compressive strength significantly greater than improperly cured concrete
bulletIncrease tensile strength for greater resistance to cracking and surface crazing
bulletImproves resistance to abrasion and corrosive action of salts and chemicals...minimizes excessive shrinkage
bulletCan be applied quickly and easily with conventional, commercial spray equipment
bulletVOC compliant ... meets the U.S. EPA Architectural Coatings Rule requirements.

Physical Properties
DRYING TIME: Depends on weather conditions and coverage, but will generally dry in 1-1/2 hours. Restrict foot traffic for at least 4 hours, 12 hours is preferable.
FLASH POINT: Greater than 210F (99C).

Application Tools

Manual Sprayer

Power Sprayer


PREPARATION: Application equipment must be clean and free of any previously used materials.

MIXING: 1100-CLEAR Series Curing Compounds are homogenous resin-base materials, which do not normally require mixing. However, after prolonged storage, they should be stirred thoroughly before using. See CAUTION paragraph. NOTE: In the container, 1100-CLEAR Series Compounds appear ivory in color, however they dry to a clear transparent coating with a very slight amber tint.

METHOD OF APPLICATION: Apply in a uniform film to horizontal surfaces as soon as the surface water disappears and the surface will not be marred by walking workmen. On vertical surfaces, apply promptly after the forms are removed. May be applied with a typical commercial hand or power sprayer. Use a Chapin 8005, or equivalent spray tip that produces a flow of 1/2 gallon (1.89 liters) per minute under 40 psi (.276 MPa) of pressure.

COVERAGE: Approximately 200 ft./gal. (4.91m/L).

DRYING TIME: Dries in approximately 1-1/2 hours. Restrict foot traffic for at least 4 hours, 12 hours preferably.

CLEAN-UP: Prior to drying, clean-up can be accomplished with soap and water. Once dried, it will be necessary to clean-up with Mineral Spirits or other suitable petroleum solvent.

5 gallon (18.93 liter) Pails
55 gallon (208.20 liter) Drums

ASTM C 309, Type I, Class B
AASHTO M 148, Type I, Class B

HEALTH HAZARDS: Direct contact may result in mild irritation. Refer to Material Safety Data Sheet for complete health and safety information.

Do not apply if concrete temperature is less than 40F (4C). DO NOT MIX WITH CURES CONTAINING SOLVENT OR ADD SOLVENTS TO "WATER-BASE" CURES SEPARATION WILL OCCUR. SURFACE MAY DISCOLOR DUE TO OVER-APPLICATION. KEEP FROM FREEZING. Do not paint or apply resilient flooring over any 1100-CLEAR cured surface without first checking the specifications and securing the approval of the paint or resilient flooring manufacturer. If removal is necessary, use SEALTIGHT ULTRITE DEGREASER.
