PORCELAIN & CERAMIC TILE

CERAMIC/PORCELAIN TILE - GENERAL .1

Apply tile or backing coats to clean and sound surfaces.

.2

Lay out work so that fields are centred on areas, with no tiles of less than half-size included. Maintain heights of panels in full courses to nearest indicated dimension.

.3

Lay-out and install tile surfaces in accordance with tile pattern drawings. Advise Consultant of problems encountered achieving patterns illustrated prior to installation.

.4

Fit tile around corners, fitments, fixtures, drains and other built-in objects. Maintain uniform joint appearance. Cut edges smooth and even.

.5

Maximum surface tolerance 1:800.

.6

Make joints between tile uniform and approximately 1.5 to 3.0 mm wide (1/16 to 1/8 in.) wide, plumb, straight, true, even and flush with adjacent tile. Ensure sheet layout not visible after installation. Align patterns/joints of wall and floor tiles.

.7

Make internal angles square, external angles rounded (bullnosed).

.8

Use round or bullnose edged tiles at termination of wall tile panels, except where panel abuts projecting surface or differing plane (internal angle).

.9

Install manufactured control joints at ceramic tile (CT and CMT types) flooring directly over concrete slab pour joints. Caulked joints are not acceptable as control joints.

.10

Install specially formed, non-ferrous metal divider strips at junction of tile flooring and dissimilar materials.

.11

Allow minimum 24 hours after installation of tiles, before grouting.

.12

Prevent traffic and work on newly-laid floors by barricading areas for at least 48 hours following installation.

CERAMIC/PORCELAIN TILE - MORTAR BED INSTALLATION .1

Place tile in accordance with applicable Details 301EJ-97 to 324RF-97 as listed in the Specification Guide and Installation Manual 09300 (1997) published by the Terrazzo Tile and Marble Association of Canada (TTMAC).

.2

All floor tile for "Wet" areas where excessive moisture and barefoot traffic prevails such as showers, drying rooms, wet area toilets, etc. shall be set in nominally 38 mm portland cement mortar setting bed which includes thickness of tile. Apply tile with neat cement only. "Thinset" mortar is unacceptable for these areas but shall be used in dry areas. Filename: 09310-CeramicTile.2011119.DOC

PORCELAIN & CERAMIC TILE

.3

Precede application of setting bed with a scratch coat of sufficient material and pressure to form good, full key and full bond on masonry or concrete surfaces. Bring scratch coat to an even surface ready to receive mortar setting bed. Scratch to a rough surface. Allow to dry and cure. Reinforce scratch coat on walls, curbs and thin mortar bed on floors with selffurring bronze woven wire cloth, 2-1/2 mesh as specified, to resist shrinkage and cracking.

.4

Apply mortar bed in uniform thickness and to follow slopes indicated to produce required slopes to drains.

.5

Use sub-screeds and floating method of installing mortar bed on the floor.

.6

Soak tile at least 1/2 hour in clear water. Remove from water and stack on edge to drain off excess water before setting. Do not set tile that has free water on the back or shows drying out of any part.

.7

Bring every fourth course, vertical and horizontal, to plumb, straight and/or level continuous lines.

.8

Thoroughly back up with mortar all cove, cap, nosing, trimmer and moulded or shaped pieces and secure firmly in place.

.9

Leave or cut openings to correct sizes to receive accessories, fittings, or other built-in work. Drill tile for hardware and for pipes where possible; otherwise at pipes and fittings, fit tile closely so that escutcheons cover cuts.

.10

Cut and grind tile accurately, and without damage, to fit openings and at intersections and against trim finish. Rub exposed edges smooth with abrasive stone.

.11

Lightly tap tiles with a solid object. If there is a hollow sound, remove tile, check for adhesion and re-tile area.

.12

Use cove base at mortar bed tile installations - wet locations.

CERAMIC/PORCELAIN TILE - THIN-SET INSTALLATION .1

All floor tile on this project is to be installed using mortar bed installation methods.

.2

Base installation may be of thin-set type.

.3

Use dry thin-set mortar as specified in accordance with manufacturer's directions.

PORCELAIN & CERAMIC TILE

Place tile in accordance with Specification Guide and Installation Manual 09300 (1997) published by the Terrazzo Tile and Marble Association of Canada as follows: .1 Detail 305W-97 for wall tile on water resistant tile backer board (cement board). .2 Detail 303W-97 for wall tile on masonry. .3 Detail 310F-97 for floor tile set in mortar bed (include waterproof membrane at wet areas). .4 Detail 311F-97 for floor tile set in thin-set method (dry areas only). .5 Detail 310F-97 at sloped floors in showers and/or drying areas (also applicable for flat floor slab/sloped mortar bed) - see also Details 302W-97 and 303W-97 for possible wall conditions. Use 4.8 mm notched trowel for application of adhesives, bond coats, etc.

CERAMIC/PORCELAIN TILE BASE .1

Install in accordance with TTMAC Details 303W-97 or 302W-97 depending upon floor/wall interface conditions.

.2

Cove Base: Make transition from floor detail condition to wall detail condition in such a manner as to maintain structural integrity of transition, avoid cracks at base locations, and to allow even alignment of base tiles with both floor and wall tiles. Use cove-type ceramic tile base at all mortar bed (floor tile) installations and at all (thin set floor tile) locations where floor and wall tile meet - wet locations.

.3

Top-Set Base: Gap under base at hard surface flooring shall be fully filled with grout to prevent seepage of water during floor cleaning operations. Use top-set ceramic tile base at thin set tile installations at dry areas.

CONTROL JOINTS AND CAULKING .1

Install/fabricate control joints at ceramic tile at the intersection of all walls and ceilings in all tiled areas, over any similar joints in concrete or masonry, at junction of different materials and as shown. Form by temporarily blocking out the joint as the work proceeds, extending clear through the tile, setting bed to the scratch coats.

.2

Install pre-manufactured control joint strips at floor tile installations (caulked control joints not acceptable). Install at cold joints in concrete pours at floor slab, at all significant cracks in concrete substrate and at all locations where supporting (suspended) structure changes direction (inspect from below) and is likely to develop cracks due to differential flexing or deflection. Co-ordinate locations with Consultant.

.3

Unless shown otherwise control joints shall be 6 mm wide at walls, 10 mm wide at floors.

Caulk tile control joints and around piping and fittings extending through tiled surfaces. Tool to a smooth, flush surface, free from air bubbles and contamination. Provide backer rod under sealant.

GROUTING .1

Remove all spacer string, wet joints and tile that have become dry before grouting. Force maximum grout into joints using trowel, squeegee or brush application method.

.2

Scrape off excess grout using rubber squeegee in accordance with manufacturer's directions. Grout joints (in finished condition) are to be slightly concave with edges of joints slightly below top surface of tiles. Excessively low or deep joints will be rejected by Consultant. Rejected joints shall be raked out and re-grouted.

.3

Rinse tile and grout areas with water once grout has achieved partial set in accordance with manufacturer's directions. Buff with cloth to remove surplus grout.

.4

At all floors, walls and other areas, use polymer modified grout, coloured. Grout colour(s) to be selected by Consultant.

CLEANING .1

Clean all tile surfaces at proper time (in grout set period) to remove grout "haze". Rinse tile areas thoroughly with clean water.

.2

After grouting has cured, clean and polish tile. Cleaning shall be in strict accordance with TTMAC recommendations for treating new work as specified in its 'Maintenance Guide'; the specific system shall be as required for the type of tile to be cleaned. Do not use acid for cleaning.

.3

Clean all tile surfaces again just prior to turning these areas over to Owner.

FLOOR SEALER AND PROTECTIVE COATING .1

Protect all tile surfaces from construction soiling until tile/grout sealers have been installed/applied.

.2

Apply proper sealer for each type of tile/grout combination in accordance with manufacturers instructions and TTMAC recommendations and after consultation with Owner's maintenance personnel. Sealer is not required at epoxy grouts.
