Do wall tiles need expansion joints?

"One of the most basic and important facts an installer should know when working with ceramic (including porcelain, glass, and natural stone) tile is to always have expansion joints in place. If expansion joints are not part of the installation, failure is lurking in the shadows waiting to strike.

Where do you put expansion joints in tiles?

On suspended floors, stress-relieving joints should be inserted where flexing is likely to occur...for instance, over supporting walls or beams. And, as always, joints must be situated directly over any joints in the substrate, and at any changes in the substrate, such as timber to screed.

Should there be a gap between tile and wall?

Use caulk to fill a gap between tile and wall. In fact, where a tile floor meets a wall, there should be a 1/8 inch (6 mm) gap between the tile and the wall. This helps account for heat expansion and your house settling. If your tile is flush against the wall, a settling house can crack tiles or grout.

Do you leave expansion gap for tile?

When you install ceramic tile on the floor, you must take care to create an expansion joint between the walls and the tiled floor. The Tile Council of North America recommends at least a quarter-inch gap between the tile floor and the walls. Never fill this gap with grout, because tile grout is not flexible.

Do wall tiles expand?

Ceramic, porcelain, and stone tile expands and contracts with thermal and moisture changes in the environment as do all building materials. The expansion or contraction will rarely be seen with the naked eye. However, it is still present.

Do you grout where tile meets wall?

Grout fills the joints between tiles.

The sole purpose of grout is to fill the spaces between tiles after the tiles have been glued in place on a floor or on a wall. Grout keeps the tiles from shifting, and also protects the edges of tile from chipping. There are two types of grout, sanded and unsanded.

How do you fill gap between wall tiles?

If you're fixing a gap between a tile floor and wall, such as in a shower or a bathroom, go with a silicone caulk so you can create an airtight, waterproof seal. Look for silicone caulk at home improvement stores, hardware stores, and online. Silicone caulk is generally clear in color.

Are expansion joints necessary?

Expansion joint failure can happen for several reasons, but regardless concrete needs a buffer as it goes through the natural cycles of expansion and contraction. So, this has always been the case, and this is why expansion joints are necessary.

How wide should a tile expansion joint be?

Australian NATSPEC recommends rectangular bays at 3 metre to 5 metre spacings. The Tile Council of America's Handbook to Ceramic Tile Installation suggests joins at 12 to 16 feet (3.6 to 4.8 metres) for all external tiled pavement and for interior tilework exposed to sunlight.

Can you lay porcelain tile without grout lines?

Well, the short answer would be a simple no – you should not attempt to install tile without grout.

Can you use caulk instead of grout between tiles?

Caulk is strong enough to adhere to tile surfaces without crevices. Caulk is flexible enough to adhere to two different materials such as glass and tile. Caulk may shrink or dry out over time, which is why it shouldn't be used in large installations or as a replacement for grout.

Do you grout between tile and wall in shower?

Grout, which is a cement-based material, is great for filling the spaces between tiles. But it isn't flexible enough to stay intact where a shower pan or tub meets surrounding walls. Nor is grout the right material for filling the corner joints on the walls. For these spaces, the right material is caulk.

What is the difference between a control joint and an expansion joint?

Control joints can be isolated within the plane being treated (brick facades, concrete sidewalks) while expansion joints must bisect the entire structure thereby creating a gap throughout all of the building elements—foundation, walls, curtainwalls, plaza decks, parking decks, floors, and roof.

Should wall tile sit on floor tile?

Experts recommend leaving at least a quarter-inch of space between your floor and wall tiles when installing. It would help if you didn't fill this gap with grout. Grout is not flexible and can't handle the floor and wall movement.

Can you tile over expansion joints?

Some manufacturers have proprietary products where they will guarantee a tile installation (when their products are used in accordance with their methods) over control joints, so long as vertical deflection does not occur. However, expansion joints must be used in the tile layer.

What is the use of joints in tiles?

Movement joints must be installed in certain areas and positions to prevent tiles or grout from cracking...and in some cases prevent the tiles from tenting and becoming debonded from the substrate. A movement joint is the interruption of the surface to allow for movement.

What is a cold joint in tile?

A cold joint is formed when one mortar setting bed has cured and another adjoining mortar bed is placed next to it. The common cold joint locations are found at the place where the mortar and tile backsplash and counter top meet and where the mortar and tile shower floor and wall meet.

What are tile expansion joints?

According to the NTCA (National Tile Contractors Association) Reference Manual, an expansion joint is, “A joint through the tile, mortar, and reinforcing wire down to the substrate.” By integrating these “stress relievers” into the tile assembly, expansion and contraction take place without compromising its integrity."

What happens if you don't put expansion joints in concrete?

Concrete expansion joints give the slabs just enough room to move which helps prevent cracks & buckling. Without these joints, even a little movement creates pressure and stress on the concrete. Eventually weak spots can crack or buckle.

How often should you put expansion joints in brick walls?

With respect to horizontal expansion joints for vertical movement the outer leaf should be supported at intervals of not more than every third storey or every 9 metres whichever is less.

Should you caulk around tile?

Since you are joining two different materials together, you should use caulk in the space where the floor tile and tub meet. Grout is not flexible, so it's not the best material for the job, while caulk allows for movement and also provides a better sealant.
