You need to apply a layer of carpet adhesive or double-sided carpet tape to the back of indoor/outdoor carpeting so the material won't move, roll up or shift.
Pour a bit of underlayment adhesive around the perimeter of the room. This will hold the carpet padding in place as you install it. The padding should cover the entire floor, but should not overlap. Tape the seams together using duct tape, but do not add flooring adhesive anywhere by the perimeter of the room.
As a general rule, you can lay carpet over concrete. Concrete provides a stable subfloor for carpet, and carpet can be installed on it using the tried and true method that virtually all carpet installation contractors use. You can also install it yourself, however, you need many specialized tools.
It will stay put with a quality rug pad. Rug pads provide comfort. Most outdoor rugs are fairly thin so adding a pad helps to make them more comfortable to walk on. Look for a thick rug pad to give yourself an extra soft surface to walk on.
Outdoor carpet is often made from UV-stable fibers like polyethylene and polypropylene, meaning it's not going to fade in direct sunlight. It's also mold and mildew resistant, and even water-resistant.
The answer to this question is yes, off-course you can. As long as you choose a rug that is designed to be used outdoors and is made of a breathable material, you should be able to put it on grass and not worry about your lawn.
The second, more attractive solution to stopping fraying of a piece of carpet is to bind it. You can take your carpet in to a carpet shop and have them bind it with a binding machine, or you can bind it with a carpet binding tape such as Instabind. Doing this will turn a carpet piece or remnant into an area rug.
Outdoor rugs are not often waterproof. But they are water resistant. Simply put, they absorb less water than most indoor rugs, and they dry a lot quicker after getting wet. Thanks to these characteristics outdoor rugs can be left outside and stay outside even in the rain.
Outdoor rugs are designed to be outside all year round and can withstand sun, rain, sleet, and snow.
Why do I need an outdoor rug? An outdoor rug serves the same purpose as an indoor area rug: it pulls your seating area together into a single, unified space that's inviting and comfortable. It shows an attention to detail, allowing you to create a truly personalized decor for your yard.
Almost all outdoor rugs are made of synthetic materials which are not as absorbent as natural materials. This means that outdoor rugs of synthetic material dry quickly and are fairly resistant to dirt and stains.
The damp-proof membranes installed in concrete floors to stop moisture rising through them can be ineffective. As such, it's vital you seal your concrete floor properly before laying any carpet. Any moisture that does reach your carpet can cause it to become moldy and start to rot.
For tack strip-free installation, use an industrial carpet adhesive called carpet seam epoxy. Its ultra viscous synthetic latex resins make great replacements to tackless strips. You can use epoxy on wood and concrete. It doubles as a seam adhesive to stop the edges of the carpet from getting frayed.
As concrete is a cold hard surface and a carpet creates a warm layer on top, there is a danger of condensation and damp forming on the underside of the carpet. For the best results, invest in a good-quality synthetic underlay to provide extra cushioning and a barrier between your carpet and the floor.
Frothed foam padding is a good choice to use on concrete floors, because it responds well in heavy-traffic areas. This can be a plus for carpeting a family room or recreation room that has a concrete subfloor. Frothed foam is densely packed and will adhere well to the concrete and the carpet backing.
Use the carpet adhesive suggested by the carpet's manufacturer. Start at one side of the room and unroll the carpet padding over the adhesive-covered cement. Lay the padding as smoothly and evenly as possible, facing the side with the waffle pattern upward. Go back and smooth out any bumps once the padding is laid.
