4.  Remove existing resilient floor covering; remove all residual adhesive, 
paint or other contaminants following RFCI recommended work 
practice.  
5.  The use of adhesive removers or solvents in the abatement or removal 
of existing or old adhesives on concrete prohibited and may void any 
warranty.  
6.  Perform corrective actions necessary for elevated moisture or high 
alkalinity conditions.  
7.  Surface Flatness for all Subfloors: The surface shall be flat to 3/16” 
(3.9 mm) in 10 ft. (3050 mm) and 1/32” (0.8 mm) in 1 ft (305 mm) 
Bring high spots level by sanding, grinding etc. and fill low spots. 
Smooth surface to prevent any irregularities or roughness from 
telegraphing through the new flooring.  
Leveling and Patching For concrete subfloors, use only high-quality Portland 
cement -based materials (minimum 3000 psi compressive strength 
according to ASTM C109). Mix with water only, do not use latex. 
CAUTION: Do not lightly skim coat highly polished or slick power troweled 
concrete surfaces. A thin film of floor patch will not bond to a slick subfloor 
and may become a bond breaker causing flooring to release at the 
interface of the subfloor and patching material. If in doubt, perform a bond 
test prior to commencing with the installation.  
WARNING: ASBESTOS & SILICA - Refer to the current Resilient Floor 
Covering Institute (RFCI) document “Recommended Work Practices for 
Removal of Existing Resilient Floor Coverings” for guidance (www.RFCI.com). 
CONCRETE 
•  The concrete must be free of any curing compounds or adhesives. 
Even after old glued down carpet has been removed, and the subfloor 
has been scraped, it should NOT be assumed that the concrete is 
porous. Often the old adhesive has sealed the floor.  
•  A porosity test, using water, should be taken. Be aware that porous 
subfloors may take a different adhesive than non-porous subfloors. 
See Manufacturer adhesive instructions. 
•  If oil, grease, or other contaminants have deeply penetrated the 
concrete, and cannot be thoroughly removed, luxury vinyl flooring 
cannot be installed. If latex liquid has been used to seal off old cutback 
adhesives, the concrete has become non-porous.
