Wood Installation
Mu Wood Installation Instructions

MU wood tiles, like any wood product, can be used on floors, walls, backsplashes, etc, but should NOT be used in a wet location, that is, constant exposure to water. Occasional exposure, like a kitchen backsplash, is fine, but a tub backsplash/surround would not be recommended. All wood tiles (with the exception of 'Teak' which holds its oils naturally) are pre-soaked for several hours in a penetrating sealer, and are then finished in a matt urethane finish. The wood needs no additional sealing or finishing; although, if it is to be used in an area exposed to dampness, such as steam in a shower area, you may wish to add a finish coat of urethane to the front and edges of the wood. Remember, 'MU' is NOT to be used in a 'WET' location. Please note that the first 6-8 inches of floor space in front of a shower dam or bathtub are frequently exposed to large amounts of water, and for this reason, we recommend installation of a border of non-wood material for that area, that is, do not butt MU wood tiles up against a bathtub or shower dam. Clean like any pre-finished wood, just a damp mop or towel, no chemicals should be used that can scratch or dull the finish. In our tests, the wood was not affected by changes in temperature or humidity.

All wood tile products should be delivered to the job site to acclimate for several days prior to installation, just like hardwood floor products.

Remember, 'MU' is NOT to be used in a 'WET' location.

With regard to installation, EPOXY thinset and grout must be used.  We recommend Laticrete 'Latapoxy 300' Thinset and Laticrete 'SpectraLOCK Pro' grout.

All wood tiles should be installed on a solid, non-flexible, non-water absorbing substrate, such as hardieback, DensShield Tile Backer, or other similar product, to avoid warping of installation. Please refer to the more detailed instructions found in the Price Binder 'MU' section.

G. Grouting or Pointing:NOTE TO SPECIFIER: select one of following and specify color for each type/color of rearmesh-mounted wooden tile, mosaic, paver, trim unit:

1. Chemical Resistant, Water Cleanable Tile-Grouting Epoxy (ANSI A118.3): Follow manufacturer's recommendations for minimum cure time prior to grouting. Store liquid components of LATICRETE® SpectraLOCK(TM) PRO Grout for 24 hours @ 70-80°F (21-27°C) prior to use to facilitate mixing and application. Substrate temperature must be 40-95°F (4-35°C). Verify joints are free of dirt, debris or grout spacers. Sponge or wipe dust/dirt off tile faces and remove water standing in joints. Apply grout release to face of absorptive, abrasive, non-slip or rough textured tile that are not hot paraffin coated to facilitate cleaning. Cut open pouch and pour LATICRETE SpectraLOCK PRO Grout Part A Liquid into a clean mixing pail. Then open pouch and pour LATICRETE® SpectraLOCK(TM) PRO Grout Part B Liquid into the mixing pail. Mix by hand or with a slow speed (<300 rpm) mixer until the two liquids are well blended. Then, while mixing, add LATICRETE SpectraLOCK PRO Grout Part C Powder and blend until uniform. Install LATICRETE SpectraLOCK PRO Grout in compliance with current revisions of ANSI A108.1 (A-1 through A-3) and ANSI A108.6 (A-4.4.1, A-4.4.3 through A-4.4.4). Spread using a sharp edged, hard rubber float and work grout into joints. Using strokes diagonal (at 45° angle) to the grout lines, pack joints full and free of voids/pits. Then hold float face at a 90° angle to grouted surface and use float edge to squeegee off excess grout, stroking diagonally to avoid pulling grout out of filled joints. Once excess grout is removed, a thin film/haze will be left. Initial cleaning of the remaining film/haze can begin approximately 20-30 minutes after grouting (wait longer at colder temperatures). Begin by mixing cleaning additive packet with 2 gallons (7.6 l) of clean water in a clean bucket to make cleaning solution. Dip a clean sponge into the bucket and then wring out cleaning solution until sponge is damp. Using a circular motion, lightly scrub grouted surfaces with the damp sponge to dissolve grout film/haze. Then drag sponge diagonally over the scrubbed surfaces to remove froth. Rinse sponge frequently and change cleaning solution at least every 50 ft2 (4.7 m2). Discard sponges as they become gummy with residue. Within one (1) hour of finishing first cleaning, clean the same area again following the same procedure but utilizing a clean white scrub pad and fresh cleaning solution. Rinse scrub pad frequently. Drag a clean sponge diagonally over the scrubbed surfaces to remove froth. Use each side of sponge only once before rinsing and change cleaning solution at least every 50 ft2 (4.7 m2). Allow cleaned areas to dry and inspect tile/stone surface. For persistent grout film/haze (within 24 hours), repeat scrubbing procedure with undiluted white vinegar and clean pad. Rinse with clean water and allow surface to dry. Inspect grout joint for pinholes/voids and repair them with freshly mixed LATICRETE® SpectraLOCK(TM) PRO Grout. Cautions: Do not use undiluted white vinegar on polished marble or limestone unless a test spot in an inconspicuous area indicates no change in finish appearance; Do not use acid cleaners on epoxy grout less than 7 days old.

Use the following LATICRETE System Materials:

LATICRETE® SpectraLOCK(TM) PRO Grout (Best Option)

H. Expansion and Control Joints: Provide control or expansion joints as located in contract drawings and in full conformity, especially in width and depth, with architectural details.

1. Substrate joints must carry through, full width, to surface of tile, brick or stone.

2. Install expansion joints in tile, brick or stone work over construction/cold joints or control joints in substrates.

3. Install expansion joints where tile, brick or stone abut restraining surfaces (such as perimeter walls, curbs, columns), changes in plane and corners.

4. Joint width and spacing depends on application - follow TCA Handbook for Ceramic Tile Installation Detail EJ-171 Expansion Joints or consult sealant manufacturer for recommendation based on project parameters.

5. Joint width: >=_ (3mm) and <=1 (25mm).

6. Joint width:depth ~2:1 but joint depth must be >=_ (3mm) and <=_ (13mm).

7. Layout (field defined by joints): 1:1 length:width is optimum but must be <=2:1. Remove all contaminants and foreign material from joint spaces/surfaces, such as dirt, dust, oil, water, frost, setting/grouting materials, sealers and old sealant/backer. Use LATICRETE® Latasil 9102 Stone Primer for sandstone and limestone installations. Use LATICRETE Latasil 9118 Swimming Pool Primer for underwater or permanent wet area applications. Install appropriate Backing Material (e.g. closed cell backer rod) based on expansion joint design and as specified in § 07920. Apply masking tape to face of tile, brick or stone veneer. Use caulking gun, or other applicator, to completely fill joints with sealant. Within 5-10 minutes of filling joint, 'tool' sealant surface to a smooth finish. Remove masking tape immediately after tooling joint. Wipe smears or excess sealant off the face of non-glazed tile, brick, stone or other absorptive surfaces immediately.

Use the following LATICRETE System Materials:

I. Adjusting: Correction of defective work for a period of one (1) year following substantial completion, return to job and correct all defective work. Defective work includes, without limitation, tiles broken in normal abuse due to deficiencies in setting bed, loose tiles or grout, and all other defects which may develop as a result of poor workmanship.

3.5 CLEANING

Clean excess mortar/epoxy from tile surfaces with water before they harden and as work progresses. Do not contaminate open grout/caulk joints while cleaning. Sponge and wash veneers diagonally across joints. Do not use acids for cleaning. Polish with clean dry cloth. Remove surplus materials and leave premises broom clean.

3.6 PROTECTION

A. Protect finished installation under provisions of §01500 and §01535. Close areas to other trades and traffic until tile being installed has set firmly. Keep traffic off horizontal Portland cement thick bed mortar installations for at least 72 hours at 70°F (21°C).

B. Keep floors installed with epoxy adhesive closed to traffic for 24 hrs. at 70°F (21°C), and to heavy traffic for 48 hours @ 70°F (21°C) unless instructed differently by manufacturer. Use kneeling boards, or equivalent, to walk/work on newly tiled floors. Extend period of protection of tilework at lower temperatures, below 60°F (15°C), and at high relative humidity (>70% R.H.) due to retarded set times of mortar/adhesives. Replace or restore work of other trades damaged or soiled by work under this section.

PART 4 - HEALTH AND SAFETY

The use of personal protection such as rubber gloves, suitable dust masks, safety glasses and industrial clothing is highly recommended. Discarded packaging, product wash and waste water should be disposed of as per local, state or federal regulations.
