Superior Concrete Bonder™ (J-41)

Product Description:

Superior Concrete Bonder is a reemulsifiable/rewettable polyvinyl acetate (PVA) emulsion for use as a bonding agent or admixture for grouts, patches, mortars, stucco and plaster. Superior Concrete Bonder is a thick milky white liquid available with a red dye upon request.

Uses:

Superior Concrete Bonder is a PVA emulsion that can be used for bonding new to new or new to old concrete in interior and some exterior applications. Superior Concrete Bonder can be uses when there is a delay between primer application and subsequent topping or coating. For example, the primer could be dry and up to nine days old and it will still rewet or reemulsify. Superior Concrete Bonder is excellent for use in bonding mortar beds for setting tile and terrazzo. It is also effective in appropriate areas when used as an admixture with cementitious products such as patching compounds, grouts, cement plasters and stucco mixes. As an admixture, Superior Concrete Bonder promotes not only a strong bond, but it also improves the curing, long term durability and resistance to cracking of the finished product. Do not use where long term exposure to constant water is possible, i.e., repair of swimming pools. In those applications, use Dayton Superior's Ad Bond (J-40).

Advantages:

• Reemulsifiable/Rewettable
• Excellent Bonding Agent/Superior Adhesive Strength
• As an Admixture - Dramatically Increases Durability, Adhesion and Curing
• Can Be Used When There is a Delay Between Primer Application and Subsequent Topping or Coating (i.e., Primer Could Be up 9 Days Old)

Technical Data:

Surface Preparation:

The surfaces should be clean and sound and all loose materials and deteriorated concrete should be removed. It should also be free of all dirt, oil, grease, paint, curing compounds and form release agents.

For increased performance, concrete surfaces should first be "roughed up" using acid etching, sandblasting, shotblasting or wire brushing. Surfaces etched with muriatic acid (10% solution) should then be thoroughly rinsed with water. Before installation, the surface should be soaked with water and then all standing water should be removed.

Bonding Coat:

Coat with Superior Concrete Bonder mixed with an equal volume of water at a coverage rate of 150/250 square feet per gallon with a brush, broom, roller or spray. Apply topping or new concrete finish after Superior Concrete Bonder is dry to the touch or clear in appearance. Recoat any areas not covered within a 9 day period. Do not attempt to use Superior Concrete Bonder on surfaces colder than 50 degrees F.

Admixture:

Dilute 2 volumes of Superior Concrete Bonder with 4 volumes of water in a separate container. Dry mix 1 part cement, 3 parts sand, then add the dry mix to the dilute Superior Concrete Bonder slowly in sufficient amounts to obtain a workable mortar. The drier the mix, the stronger the mortar. Apply mortar to the predated concrete surface. Screed and trowel to desired finish. The resultant topping or patch will have a high degree of resiliency, and will cure to a high tensile strength with lasting adhesion to existing concrete. 3/8" pea gravel may be added to mortar for thick overlayments (greater than 1" thick) to produce a more economical mixture. Run mechanical mixing equipment at slow speeds to avoid entrapping air. Do not use in areas to be cleaned with hot water or stream.

CURING

Do not use curing compounds over concrete mixes using Superior Concrete Bonder as an admixture. Surfaces should be covered with wet burlap for the first 24 hours, particularly if the weather conditions are windy or sunny and hot. Do not over-trowel the surface and clean the trowel often. Do not use below 50 degrees F.

Coverage:

Bonding Agent -150 to 200 sq. Ft./gallon after dilution 1-1 with water or 300 to 400 Sat ft./gallon with no dilution

300 lb. Sand
Add water to achieve desired consistency.

Drying Time:

Concrete repairs with Superior Concrete Bonder - wait at least 1 day at 70 degrees F. Before opening up to foot traffic. Primer- 1-2 hours at 72 degrees F.

Packaging:

1 gallon units/4 per case, 5 gallon pails and 55 gallon drums.

Cleanup:

Tools and Equipment use: Clean Water

Limitations:

Use only when water exposure is only intermittent or inconsequential. Do not use below 50 degrees F. Maintain 45 degrees F. As a minimum temperature for 48 hours. Low temperatures or high humidity will extend curing time. Do not use air entrained cement when using Superior Concrete Bonder as an admixture. Do not allow the stored product to freeze.

Warning:

May cause irritation of skin and eyes. Flush affected areas with water. Do not take internally.
