No-Glue Vinyl Sheet Questions

I am getting ready to cover the plywood sub-floor in my new basement bathoom and it looks as if no-glue vinyl sheet is the way to go. I have a couple questions:

(1) The subfloor is even and the only rough sppots are where the screws are. The paint guy at HD told me to just put down a coat of Killz 2, but I have found other information that says to use Skimcoat. I have also been told to use nothing at all. Does anybody have advice?
(2) Are there any glaring disadvantages of no-glue flooring that I should keep in mind.

ARMSTRONG Ashton Modified Loose Lay Installation System

Ashton is designed for modified loose lay installation using Vinyl Flooring Tape. The tape must be used under seams and at other selected areas with heavy movable appliances. Tape can also be used at doorways when needed. The flooring is cut and trimmed 3/16" to 1/4" away from all vertical surfaces such as walls, cabinets, pipes, etc. This gap will be covered with moldings or wall base. Do not use the tape around the entire perimeter of the room and do not install base cabinets on top of the vinyl flooring.

The flooring's unique structure creates a product that is dimensionally stable and lies flat. It will span minor subfloor irregularities and tends to hide seasonal changes that sometimes become visible at underlayment joints of fully adhered products. In certain areas of the country, where suspended wood subfloors are common and where seasonal moisture and humidity changes are severe, the movement in the wood subfloor can cause raised area or a buckle in the vinyl near a perimeter pinch point. Typically, if this happens, it will occur during prolonged periods of cold weather when indoor conditions become very dry and the wood subfloor/underlayment components dry out and shrink. Should this happen and buckle occurs, the flooring should be gently lifted or pulled back from the pinch point and retrimmed. If the flooring shows fullness at a doorway or other area where tape has been applied, gently lift from the tape and push out the fullness and rebond. Use a fresh section of tape if necessary.

Over all substrates and wherever practical, the No-Glue vinyl sheet should be allowed to float freely. This is particularly important over wood subfloors as the wood can grow and shrink with changes in moisture content. The following guidelines will help to minimize the effects of seasonal movement when installing over wood subfloors:

The flooring must be cut 3/16" to 1/4" away from all vertical surfaces such as walls, cabinets, pipes, etc., to allow an expansion zone for seasonal movement. (This gap will be covered with moldings or wall base.)
Door trim, where the expansion zone cannot be covered with wall base, must be undercut to allow for free movement of the flooring underneath.
Moldings and wall base covering the expansion zone must be raised slightly to allow for free movement of the flooring. The wall base should be nailed into the wall surface, not the floor surface.
Use Vinyl Flooring Tape only at seams, under heavy movable appliances and where needed at doorways. At doorways, transition strips, similar to a "T" molding that cover the edge of the vinyl flooring while at the same time allowing for some movement of the flooring beneath the molding are preferred. Depending on the job situation, a molding such as this could be substituted for the Vinyl Flooring Tape in a doorway to avoid further restricting the flooring. Do not use tape around the entire perimeter of the room.
Plan the layout for a minimum number of seams.
Do not install over particleboard subfloors.
Always keep the flooring rolled face-out until ready to install.
NOTE: Installation on stairs is not recommended. Installation in bathrooms is acceptable; however, the Vinyl Flooring should be used where the flooring butts up against tubs, shower stalls or toilets. To prevent water seepage and damage to the subfloor, silicone caulk must be used to seal the edges of the flooring at these fixtures. Leave a smaller gap of approximately 1/16" to 1/8" between the floor and these bathroom fixtures. Fill the gap with a neat bead of caulk at the floor/fixture juncture using a high quality, nonshrinking, pigmented caulk of appropriate color.

Step 1 - Pre-installation Care & Materials Estimating
When transporting or storing floor prior to installation, do not kink or distort.
Always roll flooring face out until ready to install.
Just prior to installation, lay flooring out flat to acclimate to conditions.
Flooring and room temperature should be a minimum of 65 degrees F (18 degrees C) for 48 hours preinstallation, during installation, and 48 hours after installation. Minimum 55 degrees F (13 degrees C) thereafter.
Plan layout for minimum number of seams.
Accurately measure length and width of room. Include recessed areas/doorways.
Allow an extra 1-1/2" of flooring on each end for trimming.
If more than one piece of flooring is needed, allow to correct pattern match at seam.

Accessory products:
Vinyl Flooring Tape
S-564 or S-595 Seam Coating Kit
Armstrong Guaranteed Installation Kit (for Do-It-Yourself installers)

Step 2 - Inspect and Prepare Subfloor; Room Preparation
Subfloor must be structurally sound, clean, dry and smooth.

Suitable Substrates:
Concrete/Ceramic/Terrazzo/Marble
Must be clean, dry, and dust-free. Check for cracks, scaling, levelness, and other damage. If installing over ceramic tile insure that the tile are firmly bonded and smoothed with underlayment as needed.
Suspended Wood Subfloors
Must have a minimum of 18" well-ventilated air space below and have a 1/4" minimum thickness underlayment panels properly installed on top. Underlayment panels should be specifically designed for use with resilient flooring. Do not install over particleboard subfloors or underlayments.
Old Vinyl Flooring
Must be noncushioned-backed and firmly bonded. Check for loose vinyl, gapped seams, cuts, tears, rips, or other damage.

Do Not Install Over:
Particleboard, waferboard or single-layer STURD-I-FLOOR panels
Existing resilient tile floors that are on or below grade
Existing cushioned vinyl flooring
Carpet
Strip wood or plank flooring

Room Preparation:
Remove all baseboard or quarter-round moldings, wallbase, appliances and furniture from room. The flooring will be cut approximately 3/16" to 1/4" away from all vertical surfaces such as walls, cabinets, pipes, etc., to allow expansion or buffer zone against seasonal movements that can occur in certain subfloor constructions due to changes in temperature and humidity. When finishing the job, moldings and/or coved wall base will cover this gap.

The decorative trim an jamb moldings at doorways should be under-cut to allow flooring t slip underneath since you can't hide the expansion zone with wall base i these areas.

After preparation work, be sure to sweep and vacuum entire work area to remove all dust and debris. Check the subfloor one last time for smoothness, cleanliness, loose areas or squeaks. Correct as necessary.

Step 3 - Cutting and Fitting

The No-Glue Vinyl Sheet flooring should be unrolled to allow the roll-up stresses to relax, lay flat and condition to the room for about 15 minutes prior to fitting. Do not lay it out over carpet or other soft surface. The subfloor should be solid to prevent distorting the flooring while working on top of it.

FOR BEST RESULTS...the Do-It-Yourself installer should use the Armstrong Guaranteed Installation Kit
The Armstrong Guaranteed Installation Kit provides the tools and instructions needed to make a pattern of the installation area. The pattern is then used to cut the flooring for correct fit before installation. If more thane one piece of flooring is used, the seams should be double-cut or trace cut as shown in the Guaranteed Installation Kit. It is important that the seam be cut in a straight line using a straight edge as guide. The knife should be held completely vertical to put a clean 90-degree edge at the seam. Seams should be cut net, not full or snug as it can result in buckles. Center the Vinyl Flooring Tape beneath the seam.

PROFESSIONAL INSTALLERS will find the No-Glue Vinyl Sheet flooring easy to cut and fit by a variety of methods including free-hand knifing, straight scribing or pattern scribing. Remember to fit 1/4" away from all vertical surfaces and to let material slip unrestricted underneath undercut door trim moldings. If seams are involved they should be pattern-matched and double-cut using a straightedge prior to placing tape under the seam.

Step 4 - Applying Tape and bonding with Tape

NOTE: Armstrong recommends Vinyl Flooring Tape to install No-Glue flooring. Carpet tapes may "read" through and impact the final installed appearance of your floor. Carpet tapes may also cause vinyl discoloration.

After the vinyl flooring has been properly fit and positioned in the room, gently fold back areas that will be bonded with the Vinyl Flooring Tape. If there is a seam it should be folded back first and the double-faced tape applied, centered under the seam. Before removing the release liner from the top of the tape, use a clean cloth and hand pressure to thoroughly bond the tape to the subfloor. Then, remove the release liner from the tape and carefully reposition the seam for a net fit. Avoid any fullness at the seam as it can lead to problems of peaking or buckling. Thoroughly roll the seam with a hand roller to complete the bond.

Other areas where heavy movable appliances are located, such as a refrigerator cutout, should also be folded back and bonded with tape. The tape should be placed in the form of a large "X", being careful to not overlap the tape. Tape may also be needed under relief cuts that were made to slip around pipes, etc., and at certain doorways where transition moldings cannot be used. Do not overuse tape and do not tape around the perimeter of the room. Wherever practical, the No-Glue vinyl sheet should be allowed to float freely over the subfloor. At doorways, transition strips that cover the edge of the vinyl flooring while at the same time allowing for some movement of the flooring beneath the molding are preferred in place of the tape.

Step 5 - Finish the Job

At doorways where the new flooring meets another floor surface, use a trim molding that covers the edge of the flooring as described above.

Replace or install baseboard moldings or coved wall base to cover expansion zone (gap) around perimeter o room. Fasten molding to the vertical surface; do not nail through new floor. Do not pinch the molding down on top of the flooring; leave a slight clearance between the molding and flooring so any effects of seasonal movement in your home due to temperature or humidity changes will be minimized.

CAUTION: Most damage to new floors is done when moving kitchen appliances. Caution should be observed so any heavy objects, particularly kitchen appliances, do not catch and tear material. When moving heavy objects into place, always use hardboard or underlayment panels to protect floor. Use strips of hardboard under feet of appliances as they are moved into final position. Tilt appliances slightly to remove strips. To further protect against heavy, sharp-edged furniture and appliance legs, the use of floor protectors is recommended. Your Armstrong retailer can help select the right protectors.

An Armstrong Seam Coating Kit must be used to coat any seams at the completion of the installation (Use S-564 for low gloss floors and S-595 for high gloss floors.) The freshly applied seam coating must be protected for several hours from dirt, dust and traffic. Follow instructions on
