Guide
Before application, forms need to be dry, clean and free of rust. Rust and dirt will transfer to the concrete surface. We often recommend treating new regular plywood with a lime water solution prior to it's first use in forming. This solution will neutralize the naturally occurring wood sugars in the plywood.
Apply form releases only during dry weather. Apply with a low pressure spray using a wide angle, low flow, flat, fan type spray nozzle. Do not use a spray nozzle designed for curing compounds, it will over apply the material. All new wood forms require a heavy application of form release prior to their first use. This application should be heavy enough to saturate the wood forms. Multiple coats of form release are often necessary to accomplish this saturation, and we recommend waiting at least 5 to 6 hours between coats. On smooth, dense forms, i.e. steel or treated aluminum, the best performance will be achieved by spraying the form release followed by wiping down the forms with a clean soft cloth.
Do not over apply. Over application can result in surface dusting and the formation of bug holes. Bugholes are caused by the "curtaining" formed by the excess release retarding the vertical movement of the entrapped air as the concrete is consolidated; rather than rising, the entrapped air follows the line of the "curtaining" creating bugholes. Neutral releases will not cause as much buildup on forms nor will they cause dusting as the reactive release will in the event of over application.
Avoid over spraying onto reinforcing steel; it may act as a bondbreaker on reinforcing steel.
All form releases do not behave the same when exposed to weather. In heavy rains, for example, some light bodies form releases will wash off the forms. We recommend checking the form release you are using for its "body" or thickness.
 Masons promotes 2 types of releases:
Reactive releases that contain fatty acids that react with the alkali in the concrete to form a soap, a process known as saponification. The thin film of soap created allows the form to easily release from the concrete.
Neutral releases contain fatty acids that is partially neutralized. These are more forgiving than reactive should they be over applied.
The following section has these 2 types of releases broken down into sections for your identification. Also included is a chart to show compatibility with your form surface. If you have any questions that are not covered in this section, call your nearest Masons Supply branch for more information.

Steelguard SP

| UN 5GSP |
5 gal. pail, 50 lbs., 36/pallet |
DESCRIPTION:
A Nonstaining form release agent formulated especially for production of high visual impact architectural precast concrete. It reacts with moisture in air to form polymerized films that are highly water and heat resistant. It produces a film that adheres to forms is not easily removed by abrasion and not affected by water or steam. This unique class of form coating offers superb release characteristics for pre-cast applications where weather exposure, abrasion, and steam leave conventional form coatings ineffective.
APPLICATION:
Recommended in hard to release situations and where abrasion can be a problem. Offers economical usage as a multiple release agent. Effective as a protective coating for long term storage of steel casting forms and pans. Effective on fiberglass forms and is recommended for use on tunnel forms as well. It is ready to use and requires no mixing, do not dilute. May be applied by all conventional methods; however, spraying is the most economical method of application. It may be applied in a very thin film on the surface of the form and allowed to "dry" on the form before pouring, usually 20 minutes. Forms should be clean and dry prior to application. When architectural or exposed surfaces are involved, it is important to remove all buildup, dirt, rust, mill scale and existing form oils prior to application.
