Selecting the proper plywood type and overlay for your upcoming project is one of the first and most important tasks that must be completed. The plywood selection process may seem daunting when you consider there are nearly 30 different APA - Engineered Wood Association that produce plywood in North America. Consulting with UFP Concrete Forming Solutions at the beginning of this process will help provide you the confidence to make the right decision for your specific project. There is no one-size-fits-all approach when it comes to plywood performance.
It is very common for traditional distributors to represent the product of a single mill. This limits your quality and price options. As the largest customer of North America's concrete forming plywood mills, it is our responsibility to keepyou informed of all options available. We will consult with you on changing market conditions, mill order files and plywood performance expectations so that you can make the best decision for your specific project.
An essential component to our success is our experienced field buyers, located throughout the country. Our buyers have decades of experience and relationships with the mills. By keeping their finger on the pulse of the mills, they keep us and, in turn, you informed of any issues or opportunities that arise.
It’s simple: with UFP Concrete Forming Solutions, you are going to get the very best from the mills. We want to make the plywood selection process easy and allow you to be confident that you are getting the best value.
Plywood Selection Process - Factors to Consider
1) APPLICATION - Is the plywood going to be used in vertical or horizontal forming?
2) HANDLING - Are you using a panelized forming system or will it be a handset system?
3) SURFACE - Is the concrete going to be covered or exposed?
4) FINISH - What kind of concrete finish is required? Gloss or Matte? Is telegraphing of wood grain onto the concrete acceptable?
5) CYCLING - How many uses do you require on the panels to complete the project?
6) CONCRETE MIX DESIGN - It is imperative that you carefully review your concrete mix in advance of selecting your overlaid plywood type. If any of the factors below are present with your mix, it may adversely affect the durability of standard plywood overlays, and a discussion regarding enhanced overlay technology is necessary:
a. SCC Mixes
b. Utilize white Portland cement
c. Utilize Type III Portland cement
d. Utilize high-range water reducers at dosage rates greater than 14 oz per 100 lbs of cementitious materials
e. Contains more than 150 lbs per cubic yard of Class C fly ash or blast furnace slag.
f. Contains more than 750 lbs per cubic yard of Type I/II Portland cement
g. Contains more than 750 lbs per cubic yard of cementitious materials consisting of any combination of Type I/II Portland cement, Class C fly ash and blast furnace slag.
h. Low slump concrete mixes that will require aggressive internal vibration
7) FORM RELEASE - Based on the overlay type you choose, you will then need to ensure the form release you intend to use is a compatible, chemically reactive product that is produced for this specific overlay and complies with all local VOC regulations. It is crucial to follow the manufacturer's application rates based on the overlay type you have selected. Nearly all APA mills factory apply form release from Nox-Crete Products Group during their manufacturing process. Nox-Crete has a chemical solution for every forming situation and use of their product is highly recommended by UFP Concrete Forming Solutions.
