MSI Paper Film Faced Mosaic
- These instructions are provided as a general guideline for the installation of paper-faced mosaic cast glass tile. An experienced, professional tile installer, who has read and understands these instructions, should perform the work.
- Some installations require a more detailed specification. Please refer to the TCNA Handbook for Ceramic, Glass, and Stone Tile Installation for additional details.
MATERIAL INSPECTION
These cast glass tile products are handmade
Variation in colour, shade, tone and size is normal. In many cases, there will
be folds, wrinkles and bubbles in the glass. These surface characteristics are
inherent to the cast glass manufacturing process and should be expected. Upon
delivery open and inspect each box of tile. The owner or owner’s
representative is responsible for determining the acceptability of the product
prior to installation as well as approving the first five square feet of the
installed tile prior to the tile installer proceeding with the installation.
Mosaic tile – verify sheet-to-sheet colour consistency by first comparing each sheet, from the backside to one another. Next, compare the faces of the sheets by laying them adjacent to one another and comparing the visible portion (edge) of the mosaic tiles.
SUBSTRATE PREPARATION
In general, there are four types of acceptable substrates for Glass Tile products:
- Concrete – Cured a minimum of 28 days, may require additional surface preparation
- Cement Mortar – Cured a minimum of 7 days Walls: Two-coat cement mortar bed reinforced with 2.5lb galvanized metal lath Floors: Wire-reinforced cement mortar bed over membrane or bonded cement mortar bed
- Cement Backer Board (CBU) – Durrock, Fiberock, Hardibacker, PermaBase, Wonderboard
- Drywall – Dry locations only
The tile installation’s substructure, location and substrate type (i.e. CBU or concrete) will influence the details of how the substrate should be prepared. The following substrate preparation methods are detailed in the Tile Council of North America’s “TCNA Handbook for Ceramic, Glass, and Stone Tile Installation” and are organized by alphanumeric designation (i.e. W244C). Use the following chart to identify which TCNA method is appropriate for your installation and refer to the current edition of the TCNA Handbook for details. The TCNA handbook is available for purchase at www.tcnatile.com.

- This method is not recommended for freeze-taw applications. Proper drainage and a pre-sloped waterproof membrane (ANSI A1118.10) are required BELOW the mortar bed
- Wood or Metal
- Use only cementitious Backer Unit (CBU) or Fiber Cement Board
- Refer to the “Pool & Water Feature Installation” document
UNACCEPTABLE SUBSTRATES
- Single-float mortar bed walls (cement mortar beds, which do not employ cured scratch coats)
- Cement mortar beds reinforced with metal lath less than 2.5 lb per square yard (i.e. chicken wire)
- Wood Products such as plywood, luan, MDF, pressboard and composites
SUBSTRATE REQUIREMENTS
- Shower receptor floors require the waterproofing below the mortar bed to be sloped 1/4″ per foot toward the drain and the weep holes to be unobstructed per TCNA B414 and B415.
- For unmounted glass tile, install horizontal, solid blocking in the framing at a maximum spacing of 36″ on the centre and such that all edges of the CBU are continuously supported.
- Solid blocking for the anchoring of fixtures, such as shower doors and towel bars, must be installed prior to installing the tile substrate.
- A vapour barrier membrane (asphalt laminated paper, 4 mil polyethylene, etc.) is required behind CBU and mortar beds in wet or exterior applications.
- Installing translucent glass tile over crack isolation/waterproof membranes or non-absorptive substrates (e.g. steam showers, coated glass mat gypsum, coated foam backer boards, etc.) is generally not recommended.
- Cement mortar beds must be cured a minimum of 7 days prior to tile installation.
- Treat CBU joints with mesh tape and thin-set per the CBU manufacturer’s instructions and allow them to cure 48 hours prior to tile installation.
SUBSTRATE BUILD-UP (installing glass tile next to thicker tile materials)
When installing Glass Tile products adjacent to thicker materials, with the
intention of the two tiles finishing in the same plane (flush), the substrate
must first be brought up to a level such that the glass tile can be installed
with the appropriate amount of thin-set.
Caution: Installing glass tile over fresh excessively built-up thin-set
mortars may result in tile cracking due to mortar shrinkage.
INSTALLATION MATERIALS
THIN-SET
The use of specific white is recommended for the installation of Glass Tile
products (see list below), however, these products will vary in their degree
of whiteness and color consistency. Due to the translucent nature of glass
tiles, the color of the thin-set will affect the installed tile’s
appearance.Some of the thin sets listed below are specifically manufactured
for use with translucent glass tile and are marketed as “bright-white” and
controlled for bag-to-bag colour consistency. Confirm the thin-set colour is
acceptable prior to installation. For projects that require multiple bags of
thin-set, select a color-controlled product or confirm bag-to-bag color
consistency. Carefully follow the manufacturer’s mixing instructions and
measure liquid/ powder to achieve maximum performance.
ACCEPTABLE THIN-SETS
The thin-set mortars listed below are recommended for use in interior,
exterior, dry and/or intermittent wet installations.
Refer to a specific “Pool & Water Feature Installation” guide for the list of
products recommended for use in submerged applications.
- BOSTIK: Glass-Mate mixed with 425 Admixture*
- CUSTOM BUILDING PRODUCTS: Glass Tile Premium Thin-Set * †
- LATICRETE: Glass Tile Adhesive *
- MAPEI: Adesilex P10 Bright White Thin-Set Mortar mixed with Keraply Mortar Additive * †
- TEC SPECIALTY PRODUCTS: Super Flex Thin-Set Mortar
NOTES
- Organic adhesives (mastic) are not recommended due to low bond strength and yellowing.
- Epoxy adhesives are generally not recommended, however, in certain applications they may be acceptable.
GROUT SELECTION
The type of grout recommended for a Glass Tile installation will vary by tile
product line, opacity and the installation’s exposure to water. In all
applications, cement-based, sanded grouts are compatible with our products
(will not scratch the tile). However, in some specific instances, unsanded
grout or urethane-based grout may be an option.
CEMENT-BASED SANDED GROUT
- ARDEX: FL Sanded Grout
- BOSTIK: Ceramic Tile Grout
- BOSTIK: Hydroment Vivid
- CUSTOM BUILDING PRODUCTS: Polyblend Sanded Grout
- CUSTOM BUILDING PRODUCTS: Prism SureColor Grout
- LATICRETE: 1500 Sanded Grout
- LATICRETE: PermaColor or Perma Color Select Grout
- MAPEI: Keracolor S
- MAPEI: Ultracolor Plus FA
- TEC: AccuColor Premium Sanded Grout
- TEC: Power Grout
CRACK ISOLATION/WATERPROOFING MEMBRANES
There is a wide variety of crack isolation and waterproofing membranes
available for use in tile installations. Each membrane product will vary in
type, application and performance; consult the membrane manufacturer for
specific recommendations and limitations. Some common membrane materials are:
- ARDEX: 8+9
- BOSTIK: GoldPlus
- CUSTOM BUILDING PRODUCTS: RedGard
- LATICRETE: Hydro Ban
- MAPEI: Mapelastic AquaDefense
- TEC SPECIALTY PRODUCTS: HydraFlex
Caution: The use of topical crack isolation/waterproof membranes directly behind the tile bond coat (thin-set) is not recommended when installing translucent glass tile.
MOVEMENT JOINTS
- Movement joints are essential for the success of most tile installations. Follow recommendations on Movement Joints EJ171 in the current edition of the “TCNA Handbook for Ceramic, Glass and Stone Tile Installation”.
- Movement joint requirements will vary based on substrate, climate and size of installation. An architect or design professional should be consulted when specifying the exact number and location of each movement joint. Not all sealants are recommended for
- submerged or heavy water use; consult sealant manufacturer for use recommendations.
PAPER-FACED MOSAIC INSTALLATION
For mosaics with a side longer than 2″, use a 1/4″ x 1/4″ square-notch trowel. For all other mosaic products, use a 3/16″ x 1/4″ v-notch trowel.
- To initiate the bond coat, use the flat side of a trowel and firmly apply a thin set to the substrate.
- To establish the proper depth of the setting bed, use a notched trowel to apply additional thin-set and comb full notches in one direction.
- Use the flat side of the trowel to flatten the notches and achieve a smooth, consistent thin-set setting bed.
- Apply mosaic sheets to the thin-set setting bed, paper side out, with light, even pressure. Periodically, check the thin-set for skinning (slight drying). If skinning occurs, remove the thin-set and reapply.
- To achieve the flattest possible surface, lightly tap the sheets with a wooden beating block and a finish hammer. To unify sheet transitions, tap from one sheet to the next.
- After 15-30 minutes, (floors can be removed sooner) lightly wet the paper. Keep the paper wet by wiping with a damp sponge several times over a 5-10 minute period. After the paper has absorbed the water, the glue will release.
- Peel the paper from the tile starting at the corner. Removing the paper while the setting material is still fresh allows for individual tile adjustment and re-inspection of colour consistency.
- Straighten individual tiles and press in any pieces that have not achieved 100% contact. To eliminate the sheet pattern pay particular attention to sheet transitions.
- After a full 24 hours (some installations may require extended cure times) use water and a nylon scrub brush to remove residual glue from the tile. Clean rinse and towel dry.
- The Grout application and cleaning process will vary based on the type and brand of grout. Refer to the grout manufacturer’s instructions for details.
- Allow grout to set up (firm) and smooth finish with a damp sponge. After approximately 2 hours remove grout haze with a lightly damp sponge.
- For final removal of grout haze, polish with a clean, soft cloth.
- Seal cement-based grout with High Performance Penetrating Sealer.
- Apply sealer with a spray bottle, paintbrush or sponge applicator.
- Allow sealer to penetrate for 1-3 minutes. Buff unabsorbed sealer from the surface with a clean cloth.
MESH-MOUNTED MOSAICS
- Glass Tile mesh-mounted products should be installed using a 1/4″ x 1/4″ square-notch trowel and standard thin-bed tile installation practices (ANSI A108.5) in conjunction with the Material Inspection, Substrate Preparation, Installation Materials and
- Sealing and maintenance specifications are found within this document.
SEALING & MAINTENANCE
Glass Tile installations should be sealed, protected and maintained.
WARNING: Certain acids will damage glass tiles. DO NOT allow products
that contain hydrofluoric, hydrochloric, muriatic or phosphoric acid to come
in direct contact with the tile.
SEALING
Glass tile is impervious and does not need to be sealed. However, cement-based
grout and natural stone should be sealed to protect against staining. Seal all
installations that include cement-based grout with either a High-Performance
Penetrating Sealer (natural look) or a High-Performance Enhancing Sealer
(colour enriching).
RESEALING
To maintain optimal performance, sealers should be periodically reapplied. The
recommended period for reapplication will vary by installation location,
environmental exposure and maintenance. As a general guideline, tile and/or
grout installed in any exterior, wet or high-traffic installations should be
resealed every 12-24 months. All other installations should be resealed every
36-48 months.
WET CUTTING MOUNTED MOSAIC TILE
Glass Tile products can be cut to meet job site dimensions with the use of a high-quality wet tile saw equipped with a continuous, smooth-rim, diamond glass tile blade. The cutting process detailed below can be used with face- mounted mosaics to fully support the tile, reduce chipping and protect the mounting system from saw overspray.
- Cover the saw tray with a piece of cement board. This provides continuous support for the sheet and prevents pieces from falling into the tray’s cutting channel.
- Adjust the blade height so the blade cuts through half of the cement board thickness.
- Cut another piece of cement board that is larger than a sheet of mosaics. Apply a strip of self-adhesive foam weather strip to one edge of the cement board.
- With the saw turned off, place the mosaic sheet, paper side up, on the cement board-covered saw tray and align the cut.
- Place the second piece of cement board on top of the mosaic sheet. Cover the portion of the sheet that is to be installed (keeper) with the weather strip side down and against the blade. The board will protect the sheet from saw overspray.
- Place downward pressure on the top layer of the cement board, turn the saw on and cut slowly. The pressure should be sufficient enough to compress the weather strip and prevent water from flowing under the board.
- Once cutting is complete, turn the saw off, carefully remove the top layer of cement board and quickly towel dry the mounting paper.
- Towel dry the back of the sheet and install as normal.
RECOMMENDED GL ASS TILE BLADES
- Alpha Professional Tools – Vetro
- Husqvarna – Superlok Glass+
- Lackmond – Pro Series Glass Tile Blade
- MK Diamond – MK 215GL or MK 215GL-XL
- Montolit – CPV
- Rockstar Diamond – G Series Blade
- Rodia – Glass Tile Blade
- Saw Master – Cheetah Series Glass Blade (Fine)
- World Diamond Source – Pro Series Glass Tile Blade
Note – To maintain cut quality, periodically dress the diamond blade with
a dressing stone.
WARNING: DO NOT DRY CUT TILE. Dry cutting causes excessive
chipping/cracking and can produce harmful dust.
DRILLING
- Glass Tile products can be drilled using a diamond core bit designed for drilling dense materials (e.g. glass or granite).
- Use sufficient water to keep the bit cool and lubricated during drilling.
- The diameter of all drilled holes must be large enough to allow a fastener to pass through the tile and substrate without making contact.
Filmed-Faced Mosaics Installation Instructions
- The following information is provided as a general guideline for the installation of Filmed Faced Mosaics; some installations require a more detailed specification. An experienced, professional tile installer, who has read and understands this information, should perform the work.
MATERIAL INSPECTION
The owner or owner’s representative is responsible for determining the acceptability of the product prior to installation. Upon delivery, open and inspect each box of tile to verify order accuracy and sheet-to-sheet colour consistency. Any discrepancies should be communicated immediately to the point of purchase. Due to the handmade, artistic nature of this product, variation in colour, shade, tone, shape and size should be expected. No adjustments will be made after installation.
SUBSTRATE PREPARATION
In general, there are three types of acceptable substrates:
- Cement Mortar – Two-coat cement mortar beds reinforced with 2.5 lb galvanized metal lath, cured a minimum of 7 days
- Cement Backer Board (CBU) – Durrock, Fiberock, Hardibacker, PermaBase, Wonderboard
- Drywall – Dry locations only
The tile installation’s substructure, location and substrate type (i.e. CBU or concrete) will influence the details of how the substrate should be prepared.

FEATURE STRIP INSTALLATION
(installing next to thicker tile materials) When installing adjacent to
thicker materials, with the intention of the two tiles finishing in the same
plane (flush), the substrate must first be brought up to a level such that the
glass tile can be installed with the recommended amount of thin-set.
Caution
Installing glass tile over fresh excessively built-up thin-set mortars may
result in tile cracking due to thin-set shrinkage.
CUTTING & DRILLING
Art glass can be cut to meet job site dimensions with the use of a high-
quality wet tile saw equipped with a continuous, smooth-rim, diamond glass
tile blade or with score and snap glass cutting tools. To minimize chipping of
tile and back coatings, fully support the tile during cutting, cut or drill
slowly and cool the cutting or drilling tool with liberal water flow.
INSTALLATION PROCESS
- To initiate the bond coat, use the flat side of a trowel and firmly apply a thin set to the substrate.
- To establish the proper depth of the setting bed, use a 3/16″ x 1/4″ v-notch trowel to apply additional thinset and comb full notches in one direction.
- Apply mosaic sheets to the thin-set setting bed, plastic film side out, with light, even pressure. Periodically, check thin-set for skinning (slight drying). If skinning occurs,remove thin-set and reapply.
- To achieve the flattest possible surface, lightly tap the sheets with a rubber grout float. Pay particular attention to the sheet-to-sheet intersections.
- After a full 24 hours (some installations may require extended cure times) starting at the corner; peel the plastic from the tile.
- If necessary, remove excess thin-set from the grout joints with a razor knife prior to grouting.
- Apply grout per the grout manufacturer’s instructions. When grouting with sanded grout, use care during application to minimize scratching.
NOTE: Grout application and cleaning process will vary based on the type and brand of grout. Refer to the grout manufacturer’s instructions for details.
