Sealers:
Shaw does not endorse any concrete or floor sealers against moisture. IF MOISTURE IS PRESENT, DO
NOT INSTALL FLOOR. Some sealers will protect the installation against alkalinity. Some also serve as a
barrier between old and new adhesives to deaden old adhesive tack, prevent plasticizer migration and
seal over dust or old cutback adhesives. Most latex- and acrylic-based sealers are compatible with Shaw
adhesives. Apply sealers to the floor according to the manufacturer’s instructions. Be sure to apply the
product evenly across the entire surface of the floor. There must be no gaps in the installation. Allow
sealer to dry completely before applying adhesive.
NOTE: Shaw warranties its Tile and Adhesives to be free of defects. The condition of a
subfloor, which causes adhesion problems due to not recommended, improper, incorrectly
prepared sealers, embossing leavers, patches, concrete, gypsum based products ect,
becomes the sole responsibility of the installer and/or manufacturer of the particular sub-
flooring product.
Existing Resilient Floors:
When installing Shaw floor tile where there is an existing resilient floor, it may be best to remove the
present floor and prepare the structural floor for a fresh application of the Shaw.
If existing resilient tile and sheet vinyl floors are in good condition and thoroughly bonded to the structural
floor, it may be possible to install. The exception is that any tile or sheet that is a cushion construction
must be removed. Note: A layer of resilient or soft underlayments like lauan may compromise the
inherent strength of Shaw Tiles and Planks to resist indentations. Do not install over more than one layer
of existing flooring.
Note: The use of levelers on non-porous subfloors will not create a porous subfloor.
Existing tile or sheet resilient floor must be stripped using Shaw approved stripper to remove wax or
other contamination and rinsed with clear water and allowed to dry. This is also the case when new sheet
vinyl is used. Very smooth or high-gloss floors need to be lightly abraded to rough up the surface to
allow proper adhesive bonding.
In some areas it has become common to use underlayment. Call Shaw Technical Support for special
requirements for such products.
Quarry Tile, Terrazzo, Ceramic Tile:
Properly cleanse substrate using a commercial degreasing/dewaxing solution. Grind any highly polished
or irregular surfaces. Fill any low spots, holes, chips and seams that may telegraph through the new
flooring. Test for porosity and use the appropriate adhesive application method. Bond tests are required.
Moisture and PH Testing:
A moisture test should be done several days before installation. The installer is responsible for moisture
testing. Shaw recommends all concrete subfloors (new and old) be tested using Calcium Chloride Test
ASTM F1869.Unacceptable results using this method would be over 5 lbs for 24 hours per 1000 square
feet. Electronic meter testing is not considered a replacement for a Calcium Chloride Test; the following
moisture readings are just an indication that a Calcium Chloride test should be performed.
Concrete subfloors must have moisture barriers installed under the slab and be determined, through
testing, to be dry and not subject to water absorption.
