DUOGARD

VOC COMPLIANT Form Release Agent

Description
DUOGARD Multi-Reactive Form Release is composed of an organic chemical which reacts 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 and a non-reactive, chemically inert ingredient to assist in clean, quick, form release and removal. These exclusive ingredients combine the effectiveness of a chemically reactive type and an inert barrier type to provide a doubly effective separation... DUO... and the ultimate in form release. DUOGARD meets maximum VOC content of 450 g/L for Form Release Compounds as required by the U.S. EPA Architectural Coatings Rule.

Uses
DUOGARD can be used on various types of forms (wood, steel, fiberglass and aluminum, as well as fiber tubes). Wood forms should be saturated prior to first use. DUOGARD increases the life of wood forms by penetrating into the wood to waterproof and prevent deterioration. It also reduces maintenance requirements on metal forms by forming a rustproof film that makes the metal form essentially self-cleaning and rust-free.

DUOGARD should be applied to fiber tube forms even though they may be pre-coated. Tubes will strip mcuh 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.

DUOGARD also cuts machine cleanup time because it minimizes concrete build-up. Pavers, trucks, mixers, spreader-finishers, buggies, chutes and other types of equipment should be sprayed daily with DUOGARD for easy cleanup and rust prevention.

DUOGARD can be applied on forms for pre-stressed and pre-cast concrete to produce a better and cleaner cast. The product will not stain or discolor concrete. DUOGARD is available in a true waterbase formula, DUOGARD II (Refer to Catalog Number 311)

bulletReady-to-use...requires no additional mixing

Application
SURFACE PREPARATION: Clean form surfaces thoroughly prior to application. Remove all rust, scale and/or previously used form release agents from the forms in accordance with good concrete practices. It is imperative, when using new wooden forms of all types, (plain wooden, plywood, rough cut, etc.) that DUOGARD be applied and re-applied until complete saturation has been accomplished prior to first use. Do not use on plaster coated molds.

METHOD OF APPLICATION: Spraying is the ideal method of application. Use a Chapin 8001 spray tip that produces a flow of 1/10th of a gallon per minute. DUOGARD 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.

Clean-up
Clean application equipment with soap and water.

Coverage
600-1500 ft/gal (14.7-36.8 m/L), depending on the type and porosity of the form surface.
