Today's Standard In Concrete Form Panel Performance

ultiPour High Density Overlaid (HDO) plywood sets a new standard in predictability of concrete finish, cost-per-pour and number of reuses in a concrete form panel. MultiPour HDO incorporates approximately twice as much overlay on each working face as Regular HDO for extra durability and smoothness. It is recommended for use in engineered systems, gang forms and job-built forms and is the ideal plywood panel for architectural concrete surfaces where high reuse is also desired.

BENEFITS
1.  Combines relatively low cost-per-pour with smooth concret.

2.  Low cost per pour. With reasonable care, up to 50 reuses can be expected in gang forms. For basements and foundations, hundreds of reuses are possible.

3.  MultiPour HDO is far more reuseable than standard BB Plyform. Cost savings can be realized after only ten pours in job-built forms.

4.  Available with one or two working faces for your choice depending on your project requirements.

5.  MultiPour HDO promotes uniform hydration, is highly resistant to concrete alkalinity, and greatly reduces surface blotching.

6.  There are no wood sugars in MultiPour HDO overlay material. Surface retardation and dusting associated with wood sugars are eliminated. MultiPour HDO also controls water migration, promoting uniform surface smoothness and hardness.

7.  Stripping is simple. MultiPour HDO releases cleanly and easily, with minimal clean-up required for the next pour. No heavy scraping or chipping of residual concrete is needed, so there's less chance of damaging the panels face.

8.  MultiPour HDO's thickness tolerance of ±1/64" means less joint offset, so panel shimming and concrete surface grinding at joints is greatly reduced.

CARE AND HANDLING
1. Apply Release Agent
Olympic Panel high density overlay panels are not factory release coated. Lightly coat panels prior to first pour and before each subsequent pour with a chemically reactive release agent that will not bond with, stain, or adversely affect concrete surfaces. This makes stripping and cleaning easier and provides more uniform concrete surfaces an all pours. Follow the manufacturer's recommendations for application. Release agents have a significant influence upon the finished concrete surface. Castor oil or forming release agents containing castor oil are not recommended.

2. Pouring and Vibrating
MultiPour HDO panels are highly resistant to abrasion and impact. However, as with any surface, they can be damaged through improper use. Rate of pour should be limited to that assumed in the design of the form. The use of rubber-tipped vibrators is recommended, and care should be exercised not to damage form faces during vibration.

3. Stripping
Most form panel damage occurs during stripping. Use wood wedges, rather than metal bars or pries, to separate the form from the concrete. Form panels should be lowered, not thrown or dropped.

4. Cleaning and Storage
Clean panels after each use, using burlap or flat, non-scratching tools such as plastic or wood scrapers. While MultiPour HDO panels are factory edge-sealed, it is important that any cut edges or exposed wood be resealed with two coats of a high quality polyurethane varnish. To minimize surface degradation and warping, store panels flat in a protected area and avoid direct sunlight.

5. Surface Repairs
Clean any concrete and release agent from damaged area and, using a putty knife, apply a solid coat of polyester-resin based auto body putty.
