DURACERAMIC INSTALLATION PROCEDURES
SAFETY
Safety for yourself and others on the job site is your responsibility as a professional flooring installer. Read and observe the following safety precautions.
-
Read and follow the safety precautions and warnings printed on the label of the installation accessory products being used. Obtain the appropriate MATERIAL SAFETY DATA SHEETS (MSDS) for information that may be required for products which may contain hazardous materials. DuraCeramic does not have MSDS because it is classified as an "article" and not a chemical. MSDS are available for the adhesive, joint sealer, and grout. You may obtain an MSDS for these products by calling or writing to your Congoleum distributor or contacting Congoleum at the address or phone number listed on this page.
-
Various safety precautions should be taken when preparing subfloors.
-
Wood and concrete: If working on wood or concrete subfloors, use proper safety precautions when sanding or grinding. Avoid creating dust. Concrete and cementitious patching compounds contain crystalline silica, which is a known carcinogen. Wood
dust is classified as a nasal carcinogen in humans. Airborne wood dust may also be an explosive hazard.
-
Resilient Flooring
-
WARNING
Do not sand, dry sweep, dry scrape, drill, saw, beadblast, or mechanically chip or pulverize existing resilient flooring, backing, lining felt, asphaltic "cutback" adhesive, or other adhesive. These products may contain asbestos fibers and/or crystalline silica. Avoid creating dust. Inhalation of such dust is a cancer and respiratory tract hazard. Smoking by individuals exposed to asbestos fibers greatly increases the risk of serious bodily harm. Unless positively certain that the product is a non-asbestos containing material, you must presume it contains asbestos. Regulations may require that the material be tested to determine asbestos content and may govern the removal and disposal of material. Whenever possible, existing flooring should be left in place and the new floor installed over the top. If you must remove old flooring material, contact your retailer or Congoleum Corporation, Installation Department, PO. Box 3127, Mercerville, NJ 08619, for a copy of recommended work practices for the removal of resilient floor coverings. These practices should be followed.
NOTICE
Various federal, state and local government agencies have regulations covering the removal of in-place asbestos containing material. If you contemplate the removal of a resilient floor covering structure that contains (or is presumed to contain) asbestos, you must review and comply with all applicable regulations. Regulations outside the United States may vary.
Copies of the Resilient Floor Covering Institute (RFCI) Recommended Work Practices for the Removal of Resilient Floor Coverings are available from:
| Congoleum Corporation |
Resilient Floor Covering Institute |
| Installation Department |
401 East Jefferson Street |
| P.O. Box 3127 |
Suite 102 |
| Mercerville, NJ 08619 |
Rockville, MD 20850 |
Please note that the RFCI Recommended Work Practices are subject to change as new practices are incorporated. It is your responsibility to determine that the recommended work practices you use are those in effect.
MOLD AND MILDEW ISSUES
Prior to removing an existing floor following the RFCI Recommended Work Practices for Removal of Resilient Floor Coverings (unless state or local law requires other measures), if
there are visible indications of mold or mildew or the presence of a strong musty odor in the area where resilient flooring is to be removed or installed, the source of the problem should be
identified and corrected before proceeding with the flooring work. In virtually all situations, if there is a mold issue, there is or has been an excessive moisture issue. Visible signs of mold or
mildew (such as discoloration) can indicate the presence of mold or mildew on the subfloor, on the underlayment, on the back of the flooring, and sometimes even on the floor surface. If mold or mildew is discovered during the removal or installation of resilient flooring, all flooring work should stop until the mold or mildew problem (and any related moisture problem) has been
addressed.
In areas where flooding has occurred, it is recommended that damaged flooring be removed following the RFCI Recommended Work Practices for Removal of Resilient Floor Coverings (unless state or local law requires other measures). Any underlayment and subfloor should be allowed to thoroughly dry and, if necessary cleaned, disinfected, and otherwise remediate consistent with the U.S. Environmental Protection Agency (EPA) guidelines referenced below. Any structural damage or signs of mold or mildew must be corrected before reinstalling
resilient flooring. This may include, for example, replacement of the underlayment and/or subfloor.
For water damage caused by leaking fixtures, the source of the moisture leak must be located and corrected. Any structural damage must be repaired and any signs of mold or residual moisture must be addressed before replacing the resilient flooring in the affected area.
To deal with mold and mildew issues, you should refer to the EPA guidelines that address mold and mildew. Depending on the mold and mildew condition present, those remediation
options range from clean up measures using gloves and biocide to hiring a professional mold and mildew remediation contractor to address the condition, Remediation measures may require
structural repairs such as replacing the underlayment and/or subfloor contaminated with mold and mildew as a result of prolonged exposure to moisture.
The EPA mold guidelines are contained in two publications "A Brief Guide To Mold, Moisture and Your Home" (EPA 402-K-02-003) and "Mold Remediation in Schools and Commercial
Buildings" (EPA 402-K-01-001), Appendix B of the "Mold Remediation in Schools and Commercial Buildings" publication describes potential health effects from exposure to mold, such as allergic and asthma reactions and irritation to eyes, skin, nose and throat. These publications can be located on EPA's website at
www.epa.gov/iaq/molds
-
Keep work areas free of obstructions, such as tools and scrap or loose tiles, and dispose of scrap materials promptly and properly to eliminate a slip or trip hazard.
-
Always use the correct lifting practices.
-
Use only UL® approved electrically powered tools equipped with a dust collector. Read and follow the safety precautions and recommended procedures for using power tools.
-
Use heavy-duty extension cords and keep them in good repair.
-
If using minerals spirits as suggested in this guide, CAUTION: Mineral spirits is a flammable material. Read and follow cautionary instructions on the labels of these products.
-
Wear non-conducting rubber-soled shoes and use a ground fault interrupter (GFI) when using power equipment in damp or wet areas.
-
Wear protective equipment when appropriate such as safety glasses, respirators, NlOSH-designated dust masks, kneepads, gloves, etc.
DuraCeramic, DuraCeramic Options and DuraPlank
DuraCeramic is an innovative flooring product with unique installation procedures that vary from traditional ceramic and natural stone. Its proven success has paved the way for DuraCeramic Options and DuraPlank.
DuraCeramic Options is a floor and wall tile with embossed lines through the center of the tile in both directions. The tiles can be installed like DuraCeramic, in a full 16"x 16" format or the embossed lines can be scored with a sharp utility knife and flexed to separate the tile to create
an 8" x 8" format. This feature provides opportunities for creating custom floors with coordinating wall, base and backsplash by adding accent colors, borders and insets or
combining it with DuraCeramic for different size formats.
DuraPlank comes in 4'1/2" x 36" planks in a variety of real wood colorations. DuraPlank features the beauty of real wood with the durability and moisture resistance of DuraCeramic. Use DuraPlank in any room in the home or combine it with DuraCeramic or DuraCeramic Options to create custom borders and insets.
DuraCeramic, DuraCeramic Options and DuraPlank are constructed with a limestone composite base that is fortified with a polymeric resin. It provides toughness and flexibility to resist breaking from normal subfloor deflection, expansion and contraction. This feature permits fast, easy installation using a pressure sensitive adhesive over a wide variety of wall and subfloor surfaces without extensive preparation.
16" x 16" DuraCeramic Options with embossed lines
Score and separate into 8" tiles for an 8" x 8" grouted installation
OVERVIEW
Use Congoleum DS 100 DuraSet Adhesive, for all approved floor and wall applications. Set tiles and planks into tacky dry adhesive for floor applications and semi tacky dry adhesive
for wall applications. PL® Polyurethane Construction Adhesive can also be used for wall, backsplash and base applications, (not recommended for flooring applications). Mortar, mastic or other adhesives are not recommended.
Depending on the desired appearance, tiles can be installed with or without grout.
-
Grouted floor and wall tiles* are laid with a1/16" to l/4" space at the joints depending on the desired grout line width. (DuraCeramic Options that are scored and separated must be grouted.) Congoleum DuraCeramic Premixed Grout can be applied immediately after tile is installed. Do not use cement, epoxy or other premix grouts.
-
Ungrouted floor and wall tiles* are laid with no space at the joints. The joints on an ungrouted tile floor should be sealed with Congoleum DS200 DuraCeramic Joint Sealer
to lock out surface water and aid cleaning. Sealing is highly recommended for all ungrouted floors. Do not use DS200 Joint Sealer on walls or other vertical surfaces.
-
DuraPlank is designed as a flooring product but it can also be installed on the walls to create a durable easy to clean surface. DuraPlank is always installed with no space
between the joints. Do not seal the joints with DS200 Joint Sealer or apply grout to joints.
* Do not apply grout or joint sealer to the embossed center lines when installing DuraCeramic Options in a full 16" x 16" format. Apply grout or joint sealer to the tile joints only.

GENERAL INFORMATION
-
Always store and transport cartons on a flat surface stacked no more than 10 cartons high. Handle tiles, planks and cartons with care. Tiles and planks can be damaged if dropped.
-
Condition the room(s) and all flooring and setting materials at a constant temperature between 65°F (18°C) and 85°F (29°C) for 48 hours prior to, during and 48 hours after installation. Thereafter, maintain a room temperature between 55°F (13°C) and 100°F (38°C).
-
When installing flooring from two or more cartons, check the code on the side of the cartons to ensure that the pattern and shade numbers are the same. Mix tiles from several different cartons to achieve the best appearance.
-
For the best visual results, the directional arrows printed on the back of the tile should be installed following the illustration in Figure 1, with tiles turned randomly, i.e. north, south, east and west. Install planks with arrows pointing in the same direction following the illustration in Figure 2.
Special Instructions for DuraCeramic Options
DuraCeramic Options is designed with embossed center lines. To create an 8"x8" format, score the embossed line(s) with a sharp utility knife (Fig. 3) and flex the tile to separate the sections (Fig. 4). If necessary, use a sanding block with 100 grit open face sand paper to remove roughness at the separation edges. Once DuraCeramic Options is separated, it must be grouted.
Fig. 3 - Score with a sharp utility knife.
Fig. 4 - Flex tile and separate into 8" tiles

Subfloor Recommendations
DuraCeramic tile and DuraPlank may be installed directly over dry concrete on all grade levels, suspended wood, qualifying old resilient floors, ceramic tile and terrazzo. DuraCeramic tile and DuraPlank can also be installed over Congoleum UnderFlor, an optional floating underlayment system by Congoleum.
The surface must be clean, dry and free of dust, dirt, grease or other extraneous material that will inhibit bonding. Thoroughly vacuum floor to remove dust.
-
Deviations in the flatness of the subfloor cannot exceed 1/16" in 1' or 3/16" in 10'. Check the surface with a straightedge and fill low areas with a portland cement-based latex patching compound. Gypsum-based patching compounds are not recommended.
-
The use of a high-quality latex primer that is specifically designed to improve adhesion may be used over wood, porous concrete and patching compounds prior to adhesive application. The primer will help seal the surface and tie down dust that can interfere with the adhesive bond. Do not use paint primers.

Moisture vapor emissions should not exceed 5 lbs./1000 ft.²/24 hrs. when tested with the calcium chloride kit. Do not install DuraCeramic tile or DuraPlank over expansion joints; instead, cut the tile neatly to each side of the joint and fill it with an elastomeric polyurethane joint filler or cover with an expansion plate cover.
Wood Floors
Wood subfloors must be structurally sound and free of movement with at least 18" of well-ventilated air space below. Single layer floors and strip wood floors must be covered with a 1/4" or heavier underlayment to achieve a total subfloor thickness of 1". Position underlayment joints so they offset the joints in the tile by at least 3". Sand underlayment joints level and fill gaps wider than 1/32" with the recommended patching compound.
CONGOLEUM UNDERFLOR
The all-in-one underlayment system for floating installations of DuraCeramic tile and DuraPlank. Congoleum UnderFlor provides an economical solution for installing DuraCeramic, DuraCeramic Options and DuraPlank as a floating flooring system over a variety of subfloor surfaces. Now, one underlayment covers it all; wood, concrete, most old hard surface flooring, gypsum topping, even old adhesive residue in painted surfaces. Congoleum UnderFlor is constructed in 6' wide rolls, and since it is a floating underlayment, it requires no fasteners or special tools so it's quick and easy to install.
Recommended Use

Congoleum UnderFlor Installation
Install Congoleum UnderFlor with the vinyl side down just prior to installation of finished flooring. Determine the appropriate seam location and direction of the underlayment (depending on the finished flooring selection).
Important
For tile installation, position UnderFlor with seams at least 4" away from the joints in the finished floor tile. (Fig. 5)
For DuraPlank always install UnderFlor with seams running perpendicular to the long dimension of the plank flooring (Fig. 6). Install planks with staggered end joints positioned at least 2" away from the seams in the Congoleum UnderFlor.
Unroll the first sheet and trim it to fit allowing a 1/4" space between the edge of the sheet and the wall.
Unroll the second sheet and position it with the seam edge butted lightly up to the first sheet. If necessary, to adjust the seam location to ensure proper placement, overlap the sheets and double-cut a new seam in the desired location. Use a straightedge and utility knife to cut the seam.
Tape the sheets together with 2" wide clear packaging tape or other thin single face plastic tape available through office supply stores and most home centers. Apply the tape, centered directly over the top of the seam edges. Roll the tape with a steel seam roller.
Suitable Packaging Tapes Include:
Do not use masking tape, fiber reinforced tape, duct tape or other thick tapes that might telegraph through the finished flooring.
Install finished flooring immediately after installing Congoleum UnderFlor.
Installing DuraCeramic Tile and DuraPlank over Congoleum UnderFlor
Follow installation instructions for the finished flooring being installed. Install finished flooring with Congoleum DS100 DuraSet Adhesive using the recommended trowel notch size. Do not apply excess adhesive. Allow adhesive to dry completely to a tack prior to flooring installation. Slight growth (buckles) in the UnderFlor may occur immediately after adhesive application. This is normal and will not affect the finished flooring installation. Install finished flooring allowing a 1/8" ti 1/4" space around the entire perimeter. If necessary to adjust or remove a tile or plank, use a heat gun to warm it up first. Roll finished flooring on completion of the installation.
All finish trim and transition moldings must be installed so they do not bind or restrict the finished flooring from moving when expansion and contraction occurs during seasonal changes. Fasten the trim to the wall not to the subfloor. Do not drive fasteners into the floor or underlayment.
Seal all areas that may be exposed to surface spills, i.e. tubs, toilet and showers with a silicone caulking.
DURACERAMIC TILE INSTALLATION
Tile Layout

Layout is slightly different for grouted and ungrouted floors. The grout line width must be added to the tile dimension for layout on grouted floors. Additional chalk lines are also used to keep the joints straight. Nominal tile size is 15 5/8" x 15 5/8". DuraCeramic Options is 7 13/16" x 7 13/16" when scored and separated.
-
It is important to avoid positioning the tile joints directly over underlayment joints or seams in UnderFlor or existing flooring. If this should occur, reposition chalk lines to offset joints by at least 3" or half of the tile dimension.
Square Layouts
-
Place a mark in the center of the floor at each end of the room. Then snap a chalk line between the marks.
-
Find the center of the line and snap a second chalk line at a right angle; use the 3', 4', 5' method to form a right angle (Fig. 7)
Fig. 7 Square Layout
-
Make a dry layout in one quadrant along the center and perpendicular chalk lines. Remember to allow the desired grout line space between tiles. A story pole (board marked with tile dimensions, including grout line width) can also be used in place of a dry layout.
-
Measure the distance between the last whole tile and the wall. If the distance is less than half a tile, snap a new chalk line one-half the dimension of a full tile away from the original chalk line (Fig. 8). This will provide a balanced layout with larger cut tile at the bor
