Mechanically Fastened/Staple-Down Installations)

• Do not install over ﬂoors that exceed one layer, as the thickness of the ﬂooring materials will prevent an adequate mechanical bond.

•

Make certain that the subﬂooring materials meet minimum requirements.

• Some tile products may be too brittle for staple penetration. Always test an area for breakage before proceeding.

IV. INSTALLING THE FLOOR

eneral Installation Tips

OTE: When installing UNFINISHED engineered ﬂooring, allow a minimum of 72 hours adhesive curing time before applying seals,

stains and ﬁnishes to unﬁnished ﬂooring. Test the moisture content of the wood in accordance with the stain/ﬁnish manufacturer’s

recommendations.

•

Do not staple or mechanically fasten products that exceed 5″ (13 cm) in width.

• Floor should be installed from several cartons at the same time to ensure good color and shade mixture.

• When possible, preselect and set aside boards that blend best with all horizontally mounted moldings used to assure a uniform

ﬁ

nal appearance. Install these boards adjoining the moldings.

•

Be attentive to staggering the ends of the boards at least 4″–6″ (10–15 cm), when

possible, in adjacent rows (Figure 4). This will help ensure a more favorable overall

appearance of the ﬂoor.

•

When installing engineered products of uniform length, begin the rows with starter

boards cut to various lengths. Avoid staggering the rows uniformly to prevent

stair-stepping. Boards cut from the opposite end of the row may be used for the

ext starter boards.

• Always allow a minimum 1/4″ (6 mm) expansion around all vertical obstructions.

Allow 1/2″ (13 mm) for ﬂoating ﬂoors.

OTE: (For Glue Down Installation) When installing products wider than 3-1/4″ (8 cm),

apply a bead of recommended wood glue to all of the end grooves prior to installing into

the adhesive. (For Staple Down Installation) When installing products wider than

-1/4″ (8 cm) but not to exceed 5″ (13 cm), apply a bead of recommended wood glue

to all of the end grooves prior to stapling down.

STEP 1: Doorway and Wall Preparation

(All Installation Methods)

ndercut door casings and jambs. Remove any existing base, shoe mold or doorway

thresholds. These items can be replaced after installation. All door casings and jambs

should be undercut to avoid difﬁcult scribe cuts (Figure 5).

TEP 2: Establish a Starting Point

(All Installation Methods)

•

Installation parallel to the longest wall is recommended for best visual effects;

however, the ﬂoor should be installed perpendicular to the ﬂooring joists unless the

subﬂoor has been reinforced to reduce subﬂoor sagging.

• When possible, always begin the layout or installation from the straightest wall,

generally an outside wall.

•

In at least two places, at least 18″ (46 cm) from the corner, measure out equal distance from the starting wall (Figure 6) and snap

a chalk line. The measurement must be the sum of the width of the ﬂooring plus an additional 3/8″ (9.5 mm) to allow for 1/4″

(6 mm) expansion space and the width of the tongue. Allow 1/2″ (13 mm) expansion when installing ﬂoating ﬂoors. Continue to

tep 3; Staple, Glue or Floating.

STEP 3: Installing First & Second Rows

(Mechanically Fastened/Staple-Down Installations)

• Use the longest, straightest boards available for the ﬁrst two rows. For random and

alternate width products, use the widest plank for the ﬁrst row. Align tongue of ﬁrst

row on chalk line. The groove should be facing the starting wall. Pre-drill 1/2″

(13 mm) from back (groove) edge, 1″–2″ (2.5–5 cm) from each end, and at 6″

(15 cm) intervals when possible (Figure 7). Fasten using 4 or 6d ﬁnishing nails or

1″ (2.5 cm) pneumatic ﬁnish nails/brads. Countersink the nails.

• Pre-drill and blind-nail at a 45° angle through the tongue of the ﬁrst row every

1″–2″ (2.5–5 cm) from the ends and spaced in 3″–4″ (7.6–10 cm) intervals.

Countersink nails to ensure ﬂush engagement of groove with the following row(s).

Continue blind nailing using this method with following rows until stapler can be

used. Alternatively use a pneumatic ﬁnish nailer and install nails/brads at the same

intervals with a minimum length of 1″ (2.5 cm).

• End-joints of adjacent rows should be staggered a minimum of 4″–6″ (10–15 cm),

when possible, to ensure a more favorable overall appearance (Figure 4).

STEP 4: Installing the Floor

(Mechanically Fastened/Staple-Down Installations)

• Always use the recommended stapler for the speciﬁc product being installed (see

“Installation Applications”). Use a minimum 1″ (2.5 cm) staple recommended by

the stapler manufacturer 1″–2″ (2.5–5 cm) from the ends spaced at 3″–4″

(8–10 cm) intervals. Continue to Step 5.

• Set compressor at 70 PSI. If tongue damage occurs, lower air pressure (Figure 8).

• Fasten several sacriﬁcial boards to the ﬂoor. At least two boards, stapled side by

side, must be used to indicate proper machine adjustments.

• Check for surface damage, air pressure setting, tongue damage, edge blistering,

etc., before proceeding. Make all adjustments and corrections before installation

begins. Once proper adjustments have been made, remove and destroy the boards.

• Install the remainder of the ﬂoor working from several cartons.

• The last 1–2 rows will need to be face-nailed when clearance does not permit blind nailing with a stapler or a brad nailer. Pre-drill

and face-nail or pneumatically nail on the tongue side, following the nailing pattern used for the ﬁrst row.

General Information for Glue-Down Applications

• Maximum adhesive working times: Urethane adhesive – 60 minutes; Armstrong ProConnect Professional Hardwood Flooring

Adhesive – 60 minutes. When not in use, keep the adhesive container tightly closed to prevent thickening. Thickening will cause

difﬁculty in spreading the adhesive.

• Open times and curing times of ALL adhesives vary dependent upon subﬂoor porosity, air movement, humidity and room temperature.

Urethane adhesive has a shortened working time in high humidity environments, whereas the working time for ProConnect and

polymeric resin adhesives will be lengthened. In areas of low humidity, open time will be longer with urethane adhesives and shorter

with ProConnect. Adjust the amount of adhesive spread on the subﬂoor accordingly. The adhesive should not be applied if subﬂoor or

room temperature is below 60°F (16°C). WORKING TIME WILL VARY DEPENDING ON JOB SITE CONDITIONS.

• Hold trowel at a minimum 45° angle (Figure 9) ﬁrmly against the subﬂoor to obtain a

40–60 ft.

(4–5.5 m

) per gallon spread rate. The trowel will leave ridges of adhesive and very

little adhesive between the ridges. This will allow you to still see the chalk lines between the

ridges and provide the recommended spread rate.

• For additional application instructions, follow the recommendations on the adhesive container.

• Proper ventilation within the room must be provided. An electric fan is helpful.

• Rolling is not required, but if desired, do not do so until the adhesive has cured for two hours.

NOTE: DO NOT INSTALL FLOORING USING RUBBER MALLETS. STRIKING THE SURFACE

WITH A RUBBER MALLET MAY “BURN” THE FINISH CAUSING IRREPARABLE DAMAGE.

STEP 3: Spread the Adhesive (

Glue-Down Installations)

• Spread sufﬁcient amounts of the recommended adhesive with the recommended trowel

(

Figure 2) in an area that can be covered in 60 minutes (see adhesive information).

• If necessary, nail a sacriﬁcial row with 1″ (2.5 cm) nails on the dry side of your chalk line to help

hold the ﬁrst row in place.

OTE: Avoid installing on the surface of the ﬂooring. If necessary, distribute weight using a

kneeler board.

STEP 4: Installing the Floor (

Glue-Down Installations)

(Figures 10a–10d)

•

Use the longest, straightest boards available for the ﬁrst two rows. For random and alternate

width products, use the widest plank for the ﬁrst row. The ﬁrst row of planks should be installed

with the edge of the groove lined up on the chalk line. The tongue should be facing the starting

all. The ﬁrst row must be aligned and seated in the adhesive, as all additional rows will be

pushed back to this original row. Remove tongue to allow for expansion space, if necessary,

on the row adjoining the wall. Continue to Step 5.

• When installing products wider than 3-1/4″ (8 cm), apply a bead of recommended wood glue

o all of the end grooves prior to installing into the adhesive.

• When installing pieces, engage the end-joint ﬁrst, as close to the side (long) tongue and

groove as possible, then slide together tightly to engage the side (long) joint tongue and

roove. To avoid adhesive bleed-through and memory pull-back, avoid sliding pieces through

the adhesive as much as possible when placing them in position.

• During the installation occasionally remove a piece of ﬂooring from the subﬂoor and inspect

he back for proper adhesive transfer. Adequate adhesive transfer is necessary to ensure

sufﬁcient holding strength.

• If the adhesive skins over and fails to transfer, remove and spread new adhesive to achieve

roper bonding.

NOTE: Clean adhesive from the surface of the ﬂoor frequently, using the recommended adhesive

cleaner. Urethane adhesives become extremely difﬁcult to remove when cured. Do not use 3M

cotch-Blue™ 2080 Tape before adhesive is removed from the surface. Use clean towels,

changed frequently, to prevent haze and adhesive residue.

• Check for a tight ﬁt between all edges and ends of each plank. End-joints of adjacent rows

should be staggered 4″–6″ (10–15 cm), when possible, to ensure a more favorable overall

appearance (Figure 4).

•

It may be necessary to align the product with a cut-off piece of scrap as shown

(Figure 11 – keep scrap angle low to avoid edge damage).

•

To eliminate minor shifting or gapping of product during installation, use 3M Scotch-Blue

2080 Tape to hold the planks together. After installation is complete, remove all of the 3M

Scotch-Blue 2080 Tape from the surface of the newly installed ﬂooring. Do not let the tape

emain on the ﬂooring longer than 24 hours. Avoid the use of masking or duct tape, which

leaves an adhesive residue and may damage the ﬁnish.

• If necessary, use weights to ﬂatten boards with bows until adhesive cures, in order to

revent hollow spots. Boards that cannot be ﬂattened should be cut in length to reduce the

bow, or not used.

•

Be sure not to spread adhesive too far ahead of your work area (Figure 10d).

• Complete the installation using this same technique for the remainder of the ﬂoor.

•

Avoid heavy foot trafﬁc on the ﬂoor for at least 24 hours. Lift the furniture or ﬁxtures back into place after 24 hours.

General Information for Floating Floors

loating ﬂoors can be installed over any structurally sound surface that meets or exceeds local building codes. Any width of ﬂooring

can be installed in this manner but wider widths are preferred.

• Plan the ﬂoor layout (in width) to avoid having to rip the last row narrower than 1″

(2.5 cm). This may require ripping the ﬁrst row to assure the last row is at least the

minimum width.

• Allow 1/2″ (13 mm) expansion around all vertical obstructions.

STEP 3: Installing the Underlayment

(Floating Installations Only)

• Install the underlayment in the same direction the hardwood ﬂooring is to be installed.

• Extend the underlayment a few inches up the wall.

• Trim excess prior to installing trim or moldings.

• The ﬂoating ﬂoor underlayment already has double-sided tape for ease of taping

the precut overlapping seams (Figure 12). If a non-adhesive underlayment is used,

tape all seams with the included tape.

STEP 4: Installing the Floor

(Floating Installations Only)

• The ﬁrst row can be installed using one of two methods after the layout has been

completed (Step 2). Allow 1/2″ (13 mm) expansion.

• Sacriﬁcial board: If the wall is not straight, scribe the ﬁrst board (Figure 13) as

necessary to maintain alignment with the chalk line. Install a sacriﬁcial board (with

a straight edge) using the appropriate fasteners for the subﬂoor. If a board is used

for the starter row make certain the groove faces the wall.

• Wedges: Align the ﬁrst row with the wall using wedges to maintain a 1/2″ (13 mm) expansion in place and to stabilize the product.

If the wall is not straight, scribe the ﬁrst board (Figure 13) as necessary to maintain alignment with the chalk line.

• Select the ﬁrst board. All

installations should begin with the

groove side against the wall using

the longest boards available.

Apply a continuous 1/8″ (3 mm)

glue bead to the inside bottom of

the groove on the end of the

board. Do not apply glue to the

groove side at this time (Item C,

Figure 14). Products with the end

tongue on the left should be

installed right to left, opposite

tongues should be left to right

(Item D, Figure 14). If a sacriﬁcial

board was used DO NOT glue

the ﬁrst row to it.

• Complete the ﬁrst row. Cut the last board allowing for 1/2″ (13 mm) clearance between the wall

and the ﬂoor. (Use the remaining end of the cut board as a starter board for any row following row three). Install a wedge on the

end of the board between the hardwood ﬂooring and the wall, allowing 1/2″ (13 mm) expansion space. Avoid installation of any

boards shorter than 16″ (40.6 cm) in the ﬁrst four rows (Item F, Figure 14).

• Use a pull bar to pull the last board into place from the opposite end. Install wedges into the gap and tighten (Item B, Figure 14).

• If any glue gets on the surface of the ﬂooring, wipe off immediately with a clean damp cloth.
