Section B: Pre-Installation Site Inspection
1. Subfloor Moisture Testing of ConcreteSpringflex can be installed in rooms with normal humidity levels on sub-floors that are firm, level, and dry. To determine if a concrete subfloor is dry, several methods can be used:
Method A: Place a sheet of plastic film on the surface of the subfloor and seal the edges with duct tape. If, after 24 hours, condensation or darkening does occur, refer to Method B.
Method B: Should method A exceed tolerance, a 72-hour calcium-chloride test needs to be conducted on the concrete subfloor (ASTM F-1869). For emission levels of up to 6lbs. of pressure, use Polyfelt with fully taped seams. For levels up to 10lbs., use 6mil. plastic underneath as a secondary moisture barrier with fully duct-taped seams. For readings in excess of 10lbs., corrective measures must be taken in order to successfully install Springflex. See section E. figure 1 for additional information on Secondary Vapor Barrier.
Section C: Preparing For Installation
1. Subfloor Tolerance:Subfloors can be any firm surface such as concrete, plywood, sheet vinyl, or smooth tiles, etc. Surface variation should not exceed 3/16" within a ten-foot radius. To Determine flatness of the subfloor, use the edge of the Springflex flooring board. Correct minor low spots by filling with tar paper or roofing felt. Extensive low spots may require a leveling compound. Scrape, sand, or grind any high areas.
2. Clean the SubfloorScrape subfloor clean and sweep up all debris from construction. Any debris left on the floor could compromise the secondary vapor barrier, in the event that subfloor moisture requires an additional layer of 6 mil. plastic.
3. Determine the Direction of InstallationDecide which direction your flooring will be installed. The rule of thumb is to run the length of the flooring with the length of the room. Other considerations are to install planks parallel to the incoming light source or parallel to the direction of traffic flow.
Section D: Expansion and Contraction Planning
1. Planning for ExpansionIt is vital in the planning of the job layout that you understand the unique nature of the Springflex product. This is not a veneer product (plywood); it is solid wood throughout. Always allow for proper expansion space around the perimeter of the floor. the rule is 1/4" expansion space for every 10 feet of width ON BOTH SIDES! The rule for expansion on the length is 1/8" for every 10 feet of length on both ends.
2. Expansion Space -- Doing the MathTo calculate the correct expansion space for width of floor use the following table:
Expansion Formula = 1/4" per 10 foot span each side -- 1/2" per side minimum.
20 ft. span = 1/2" expansion per side
30 ft. span = 3/4" expansion per side
40 ft. span = 1" expansion per side
50 ft. span = 1 1/4" expansion per side
