DIY: Artificial Concrete Flagstone Pathways

Place your flagstone tile mold on a flat surface. Pour cooking oil onto a paper towel and rub it along the inside of the mold.

Pour water into a bucket with the premixed concrete. Add water until the mixture is the consistency of peanut butter.

Fill the mold with concrete and run a trowel over the top to smooth it. Shake the mold to level the mixture and eliminate air pockets. Let the concrete set for 24 hours.

Turn the mold over and shake it to release the mold from the concrete. Move the tiles outside and cover them with tarps for seven days.

Brush concrete sealer onto the tile with a clean paintbrush. Let the sealer dry completely.

Lay out the tiles along your pathway. Arrange the tiles until you like the layout. Cut any tiles that need to be sized with a masonry saw.

Mix one part Portland cement with two and a half parts masonry sand. Add enough water to make a paste with a peanut butter consistency.

Lift a tile and spread ½ inch of the cement mixture on the bottom of the tile. Set the tile in place. Wipe away any cement residue with a damp sponge. Repeat for all tiles. Let the tiles set overnight.

Mix another batch of Portland cement, masonry sand and water in approximately the same ratio as in step 7. Use slightly less water to create a thicker paste.

Scoop up some of the cement mixture with a tuck pointer. Spread the mixture in between the tiles, completely filling the space. Wipe away the excess with the side of a trowel. Repeat for all of the tiles.

Dip a sponge into clean water and wipe the tiles to remove excess cement. Wipe the tiles again with a dry sponge until all of the cement and sand are removed.
