Choices that Work.
Wood
All wood substrates must be primed with Mannington Premium Universal Primer.
1. Wood subfloors require an underlayment (double layer construction) with a minimum total thickness of 1” (25 mm). Use
minimum ¼” (6 mm) thick APA rated “underlayment grade” plywood with a fully sanded face or other underlayment
panel that is appropriate for the intended usage. Install and prepare panels and seams according to the manufacturers’
instructions.
2. Wood Subfloors and underlayment panels shall have the moisture content tested using a suitable wood pin meter.
Readings between the wood subfloor and underlayment panel should be within 3% and have a maximum moisture content
of 14% or less.
3. Many times wood panel subfloors are damaged during the construction process or are not underlayment grade. These
panels must be covered with an appropriate underlayment. Underlayment panels are intended to be used to provide a
smooth surface on which to adhere the finished floor covering. It should be understood that underlayment panels cannot
correct structural deficiencies.
4. Panels intended to be used as underlayment should be specifically designed for this purpose. These panels should have a
minimum thickness of ¼”. Any panels selected as an underlayment must meet the following criteria:
• Be dimensionally stable
• Have a smooth, fully sanded face so graining or texture will not telegraph through
• Be resistant to both static and impact indentation
• Be free of any surface components that may cause staining such as plastic fillers, marking inks sealers, etc.
• Be of uniform density, porosity and thickness
• Have a written warranty for suitability and performance from the panel manufacturer or have a history of
proven performance
5. Any unevenness at the joints between panels must be sanded to a level surface. Gaps between panels, hammer
indentations, and all other surface irregularities must be filled and sanded.
6. Particleboard, chipboard, construction grade plywood, any hardboard and flake-board are not recommended as
underlayment. All have inadequate uniformity, poor dimensional stability, and variable surface porosity. Amtico LVT
Floors will not accept responsibility for adhered installation over these subfloors. QuickStix LVF can be installed over all
wood and wood composition panels provided that they are smooth, flat, structurally sound and free of deflection. If the
surface of the subfloor is not smooth, a ¼” underlayment should be installed over the subfloor. In all cases, the
underlayment manufacturer or underlayment installer is responsible for any underlayment warranties.
Existing Floor Covering
To achieve maximum product performance it is always best to remove existing floor covering and prepare the substrate before
installing new products in commercial settings. Existing flooring can adversely affect the performance properties of the new
flooring, such as indentation or adhesive bond. It is the floor covering retailer’s or installer’s responsibility to determine if the
existing resilient floor covering is suitable as an under floor for installation. If there is any doubt about the suitability of the
existing floor, remove it or cover it with an appropriate underlayment.
The existing resilient flooring should meet the following conditions:
• Be fully adhered (full-spread) and well bonded to a suitable substrate
• Consist of a single layer only
• Be free of all evidence of alkaline salts, hydrostatic pressure, or moisture from the substrate
• Not be a foam-backed or thickly cushioned product
• Not be a perimeter-fastened or loose-laid product
• Not be asphalt tile, self-stick tile, rubber tile, or surface containing residual asphalt-based adhesives
LAYOUT: Layout shall be specified by end user, architect or designer.
1. Establish center marks and determine start point to balance installation in room and have equal tile widths on opposite
sides of room. This can be facilitated by dry laying tiles and marking base lines.
2. Install rows to chalk line making sure tiles are precisely aligned with chalk line and adjacent tiles. Start straight and
stay straight.
3. Pre- cut all wall and trim piece before the removal of the protective paper. When all preparatory work is satisfactorily
completed, including dry fitting cut tiles (if applicable), proceed with installation. Inspect each tile for visual defects before
installing.
