How Do I Install a Concrete Paver Floor Inside?


The concrete industry has evolved over the years to create a selection of concrete pavers in numerous colors, textures and shapes. The concrete paver once used only for outdoor purposes is now used inside the house to create a rustic and warm living area. The weight of a collected group of concrete pavers requires a solid concrete base for installation. Any concrete floor basement or slab home with a concrete floor is ideal for placing concrete pavers. Lay the concrete pavers like ceramic tile except use mortar instead of grout.

Things You'll Need

  • Broom
  • Dustpan
  • Pry bar
  • Hammer
  • Carpenter's tee
  • Level
  • Pencil
  • 1/4- to 1/2-inch spacer board
  • Ruler
  • 1 x 4's, 8-feet long
  • Hammer drill
  • Masonary screws
  • Thinset mortar
  • Plastic container
  • Water
  • Notched trowel
  • Rubber mallet
  • Concrete pavers
  • Grout
  • Grouting float
  • Sponge
  • Silicone sealer
  • Paintbrush
  • Finish nails
  • Locate the center of the room. Stand in the main entrance way and walk directly across the room to the opposite wall. Have another person hold a chalk line on the opposite wall of the doorway. Take the end of the chalk line and walk across the room to the main entrance. Snap a chalk line across the floor. Use a carpenter's square and check to see the chalk line is square with the main entrance. Make adjustments to square the line before beginning.

  • Lay a dry run of pavers on the floor. Begin setting the concrete pavers along the snapped line and doorway. Add a spacer between the pavers. Use a piece of 1/4- to 1/2-inch board to create a uniform separation between pavers. Stop placing pavers once a complete paver will not fit.

  • Lay a 1x4, 8-feet long, directly against the last full paver placed on the floor. Use a hammer drill and masonry screws to secure the board to the floor on each end. This will be the guide to set the pavers perpendicular to the first row. Use more than one 1x4 according to the width of the area.

  • Lay pavers along the 1x4 perpendicular to the first set row. Place a spacer between the pavers to get uniform placement. Repeat the process on the opposite side of the center row. The design will now look like the letter T.

  • Measure the distance between the last paver on each arm of the T shape. The distance should be the same. Add the two measurements together and divide by two. This is the distance the pavers should be from the wall for centering purposes. Measure from one wall and snap a line at the determined distance. Connect the line with the end of the 1x4 secured to the floor. This is the starting place for laying the concrete pavers.

  • Remove the pavers from the concrete floor. Begin in the squared corner of the room by the last snapped line and attached 1x4. Use a grooved trowel and place a layer of thinset cement mortar over a 2-foot by 2-foot area of the cement floor.

  • Set the first cement paver. Gently push the paver into the thinset. Work each paver into the thinset as it is placed. Set the spacer between the pavers to insure uniform placement. Use a level to make sure the pavers are on a level plane. Tap any high pavers down with a rubber mallet. Add more thinset under a paver if it is too low. Repeat the process until all full pavers are laid. Let the pavers set for 24 hours to dry.

  • Cut the pavers to fit around the edge of the floor where full pavers will not fit. Place the spacer board along the wall adjacent to a full paver. Lay a paver directly over the full paver to make a stack. Place a second paver over the previous placed full paver and slide it against the spacer. Draw a line across the first paver. This is the line to cut so the paver will fit exactly in the opening. Repeat the process for each paver being cut.

  • Use a notched trowel and apply thinset to the concrete floor. Place the cut pavers along the edge making sure to insert the spacer between each paver. Let the floor sit for 24 hours to dry.

  • Mix the grout according to the instructions. Apply grout to the concrete pavers with a grouting float at a 45-degree angle. Work the grout into the spaces between the pavers.

  • Remove excess grout with a sponge. Be careful not to dig the grout out of the spaces between the pavers.

  • Wipe the entire floor with a sponge after the grout has set to remove excess grout residue. Read the instructions for proper setting time.

  • Wipe the floor with a sponge for the next three days to help the grout attain a resilient solid surface.

  • Wait one week from installation and wipe a coat of silicone sealer over the grout.
