Prepare the concrete floor by cleaning the concrete, applying metal strips at the doors, filling any voids and applying a self-leveling primer. Mix the self-leveling concrete, and pour it over the floor. Large areas require two people: one to mix and one to pour.Continue Reading
Sweep the surface of the floor, and then clean it with a pressure washer to remove oil, grease and other stains.
To contain the product to the work area, apply a metal strip to all doorways using duct tape. Make each strip taller than the intended depth of the self-leveling concrete.
Use concrete filler to patch any holes, deep cracks or pits in the floor.
Mix the self-leveling product according to the manufacturer's directions. Add water to the mix, and stir the solution using a mixing paddle and power drill.
Begin at one end of the room, and work toward a door so you don't trap yourself. Work from side to side, pouring even strips about 1 foot wide. For large rooms, enlist a second person to mix more product as you pour. Cover the entire floor in one session for best results.
