DUOGARD II

WATER-BASE CONCRETE FORM RELEASE
Cuts stripping time to a minimum and reduces form cleaning and repair.

SEALTIGHT DUOGARD II Form Release Agent is a true water-base formula designed to form a clean-release film on concrete forms, equipment and tools.

Technical Description
DUOGARD II Form Release Agent is composed of organic chemicals emulsified in water that react with the alkali content of concrete to form a release film that effectively prevents the bonding of the concrete to the form. In addition, the product also contains a high molecular weight, non-reactive, chemically inert ingredient to assist in clean, quick form release and removal. This exclusive combination of physical and chemical reactive components provides a doubly effective separation... DUO... and the ultimate in form release efficiency. DUOGARD II meets maximum VOC content limit of 450 g/L for Form Release Compounds as required by the U.S. EPA Architectural Coatings Rule.

Uses
DUOGARD II Form Release Agent can be used on various types of forms (wood, steel, fiberglass and aluminum as well as fiber tubes). DUOGARD II increases the life of wood forms by penetrating into the wood to waterproof and prevent deterioration.

It reduces maintenance requirements on metal forms because it forms a rustproof film that makes the metal form essentially self-cleaning and rust-free.

DUOGARD II should be applied to fiber tube forms even though they may be pre-coated. Tubes will strip much easier, even 60 to 90 days later. If tubes are stripped in 5 to 10 days, hand rubbing is greatly facilitated when tubes are coated with DUOGARD II.

DUOGARD II cuts machine cleanup time and minimizes concrete build-up. Pavers, trucks, mixers, spreader-finishers, buggies, chutes, and other types of equipment should be sprayed daily.

DUOGARD II can be applied on forms for prestressed and precast concrete to produce a better and cleaner cast. The product will not stain or discolor concrete.

Application
SURFACE PREPARATION: Form surfaces are to be thoroughly cleaned prior to application. All rust, scale and previously used form release agents must be removed in accordance with good concrete practices.

METHOD OF APPLICATION: Spraying is the ideal method of application... Use a Chapin 8001 spray tip that produces a flow of 1/10 of a gallon per minute. DUOGARD II may also be applied by roller coating, mopping or brushing. A thin film should be applied for maximum economy and efficiency. Runs or puddles need to be brushed out. For metal forms, the best results are obtained with a spray-on "fog" application of DUOGARD II.

CLEAN-UP: Tools and equipment used to apply DUOGARD II clean up easily with soap and water.
