Advantages Of Slate Tile Flooring

Advantages of Slate Tile Flooring

Slate tile offers a host of benefits as a flooring option. Extreme durability makes it a great product for areas that receive heavy traffic and possible moisture, such as a foyer or a bathroom. Because it is long lasting and beautiful, slate tile flooring raises the value of most properties. It is fire and slip resistant, and environmentalists like slate because chemicals are not used in its manufacture.

Disadvantages of Slate Tile Flooring

Slate tile flooring requires proper sealing and periodic re-sealing. It sometimes flakes or chips, but repair usually demands little effort. Slate tile is more expensive than many types of flooring, and certain chemical cleaners may discolor or damage the surface of the tile. Because of varied colors and patterns, it can sometimes be difficult to create a consistent appearance with slate tile. Different areas produce different colored tiles, so if you're worried about consistency, then ensure that all tiles for the job come from the same quarry.

Slate Tile Flooring Colors

A wide range of colors is part of what makes slate tile a popular flooring product. Tiles can contain tints of brown, tan, gray, blue, green, red, and orange. Veins of color often run through the tile for a striking presentation.

Slate Tile Flooring Patterns

Manufacturers sometimes cut shapes into the tile to create attractive patterns. Homeowners can also create their own floor pattern by combining tiles of different sizes and colors into a large motif.

The company has a large presence in home improvement stores and offers a variety of colors. Cabot also quarries materials from China and enjoys a large online presence. This company's tile receives high marks for its durability and wide array of colors and designs. Janeiro quarries all materials from Brazil, and products range from very basic to highly artsy. Contractors approve of Janeiro tile for its precise cut and smooth edges.

How To Install Slate Tile Floors

Slate may be installed over dry wood or cement floors. A plywood sub floor requires the use of backer board or underlayment to ensure stability. Below are all the steps for installing slate tile floors.

Setting the Tile

  1. Make sure the area for installation is cleaned and coarse-sanded (if floor is painted or varnished).
  2. Lay out the slate in the preferred pattern, cutting tile if needed with a diamond-blade wet saw.
  3. Apply two coats of penetrating sealer to all tiles. Let it dry and reapply.
  4. When the sealer is dry, start setting tile in the farthest corner of the room. Spread thinset mortar on the floor with a notched trowel and place the tile. Use 1/4-inch or 3/8-inch spacers to create grout space between each tile. Mortar and place successive tiles, moving back and forth along the floor toward the entry.
  5. Make sure each tile bonds securely by pressing the slate firmly into the thinset mortar.
  6. When all tiles are placed, allow 24 to 36 hours of curing time.

Grouting Slate Tile

  1. Make sure all equipment, joints and tile surfaces are clean.
  2. In a pail, mix penetrating sealant with grout in place of water for a stronger bond. To avoid hardening, only mix enough grout for roughly 30 minutes use. Add sealant slowly to create a damp-sand texture, and press the grout deeply between the joints with a grout float until filled completely.
  3. Wipe excess grout with the trowel or a damp sponge, and rinse these materials often with clean water.
  4. When the grout is hard set, rub vigorously with a cloth over the tiles and along the grout lines to clean.
  5. Allow the floor to cure for at least three days, but preferably for a week.
  6. Using a sponge mop, wash the floor again with clean water, and dry it with a clean cloth or towel.
  7. To finish, re-apply sealer in a thin coat with a paint pad or clean cloth, and let it dry for 24 hours.

Slate Tile Flooring Maintenance

After installation, slate tiles may flake or chip for a period of a few months. During this time, daily sweeping helps keep floors clean and dust-free. To wash slate tiles or any tile, homeowners should use a mop and stone cleaner or a neutral-pH detergent. Acidic cleaners containing vinegar or lemon can damage slate tile floors and should not be used. Mop tiles with clean water to remove soap and allow flooring to dry. In between washings, dry mop or vacuum the slate floors.

For scratches, clean and dry slate and apply mineral oil to the affected area with a soft cloth. Rub mineral oil into the scratch until it is no longer visible. Re-seal slate tile flooring every two to three years (indoors) and every one to two years (outdoors) to keep floors looking nice. Place a rug or welcome mat at all entrances to protect slate floors from outdoor dirt and gravel.
