Patio Tiles Over Concrete: Bare Slab to Outdoor Room

Start with a bare slab like this: stained concrete, a few cracks, weeds in the seams and one plastic chair. The plan below is acacia deck tiles over a 10×12 slab, a two-seat bistro set, an in/outdoor rug, string lights and two pots, for $889.81 at the time of writing. The before is an illustrative AI-generated image, not a photo of a real yard, and the after is a concept render of the same view. The render shows more plants, a round table and an extra chair than the list includes, so read it as a mood, and the table below as the plan.

Can you tile over a concrete patio?

Yes, if the existing concrete is hard and even. IKEA’s RUNNEN decking, the interlocking deck tiles in this plan, is rated for “hard, even surfaces, like concrete, stone and wood.” The tiles click together, sit on a plastic base and need no glue or mortar, so they are easy to install and the usual fix for a concrete patio you can’t pour over or dig up. Interlocking patio tiles are the renter-friendly cousin of a paver patio: nothing is permanent, and the outdoor space underneath stays as it was. If a bare slab has the charm of a loading dock, tiles are the cheapest way to hide the loading dock.

The tile is solid acacia on a polypropylene base, 11¾ inches square, nine to a pack, patio flooring that gives a slab a wood deck look without the frame. Each pack is $34.99 at the time of writing and covers about 8.72 square feet. It is for outdoor use only.

Is your concrete slab ready for deck tiles?

Check three things before you order: cracks, level and drainage. An uneven concrete slab is the one thing that spoils an otherwise easy install. Hairline cracks are fine. A slab as cracked as the one in the before image needs patching and weeding first. A wide crack or a slab that has heaved so one side sits higher than the other will make the tiles rock, and the fix comes before the tiles do. Water should run off the slab, not pool on it. If you can’t tell by eye, pour a bucket on it and watch where it goes.

That is our reading of IKEA’s “even surfaces” spec, not a published tolerance, so if the slab is borderline, ask the store or your local pro before you buy 14 packs. For the wider choice between a slab and a raised deck, our patio vs deck guide has the costs and the permit rules.

The honest math

Prices are IKEA US list prices at the time of writing, October 27, 2026. Every line is confirmed on the product page that day. Not in the total: edging strips and corner pieces (IKEA sells them separately, in dark gray at the time of writing), plants and soil, wood stain for the yearly reglaze, and a saw if you don’t own one.

Two places to save. Skip the rug and the total drops to $689.82. Tile only the seating area, say 6 × 8 ft, which is 48 sq ft or 6 packs, and the tiles cost $209.94 instead of $489.86.

What do you put on concrete before laying deck tiles?

Nothing, with this kind of tile. Interlocking deck tiles go straight onto clean concrete, with no adhesive and no grout. Sweep the slab, pull the weeds out of the seams, patch the wide cracks and let it dry. That is the whole installation prep, and it is why this is a weekend job and not a contractor job.

How many deck tile packs do you need for a 10×12 patio?

You need 14. A 10×12 slab is 120 square feet, a pack covers 8.72, and 120 ÷ 8.72 is 13.8, so 14 packs leaves a couple of spare tiles for the cuts. Add a fifteenth pack if the slab has a post or an odd corner, because cut edges waste tile.

Furnish it: bistro set, rug, lights and pots

An empty tiled slab is a floor, not an outdoor living area, so the furniture does the rest of the work. The TÄRNÖ set is outdoor furniture that folds flat, a table, 21⅝ by 21 inches, with two folding chairs: a two-seat bistro, not a dining table. It sits on the tiles without a rug underneath. For four people, swap it for a bigger set and keep the tiles.

The rug is the one extra here, and the one we would skip. Tiles already turn the slab into a floor. A rug on top is a floor on a floor. If you want one anyway, outdoor rugs need polypropylene or an indoor/outdoor-rated fiber, and a regular wool rug will mold within a season.

String lights are the best joy-per-dollar item in any outdoor living space, and the first thing to break, so check the bulbs are plastic before they stay up through a frost. The two pots are small: 7½ inches, enough for herbs or a pair of flowers, not a privacy hedge. For ideas that fit a small slab, see our small backyard patio ideas on a budget.

Are patio tiles over concrete worth it?

Worth it for a slab you are stuck with and a few hundred dollars. Skip it if you will not reglaze. IKEA says wood tiles need reglazing once or twice a year, and signs it is time include color changes, small cracks and a dry surface. Several reviewers on the product page report cracking, fading, curling or mold after one to three years. Those are customer reports, not IKEA’s claim, but they match the pattern with any wood left outside: it is less durable than the concrete under it, and wear and tear shows first at the chair legs.

If you want no upkeep at all, a bare slab with a rug is the cheapest floor you can own. A slab never asks you to find a stain in April, and a paver patio, our patio ideas with pavers shows, is the permanent upgrade if you own the place. For where each surface sits next to a porch or a covered space, see our porch vs patio guide.

Lay the tiles on a clean, level slab, and everything else on this page is easy to move around.
