Most of the time, you or your contractor will spray the concrete form and framework with a release agent or oil to prevent sticking. This is common practice with wood and steel forms. For insulated concrete forms, the styrofoam formwork often remains in place after construction, so you don’t need to treat it beforehand. Foam concrete forms made out of melamine also may not need treatment beforehand, as the material naturally won’t stick to the concrete after it’s cured.

The standard thickness for a concrete driveway is four inches for an area that holds cars and pickup trucks. Larger vehicles like motor homes, heavier trucks, and trailers should be thicker to accommodate the added weight without cracking. Plan to pour concrete five inches thick for driveways that need to accommodate large, heavy vehicles.

The method used to repair cracks in your concrete driveway will depend on the extent of the damage, but the most common method for small cracks is to use a driveway resurfacing compound. This solution is either cementitious or made of polyurethane, and it will seal the crack and make your driveway appear undamaged. 

For more severe cracks, you will likely need to hire a professional driveway repair service. They can use mudjacking, epoxy injections, partial driveway replacements, or a combination of these to fix more serious cracks in your concrete driveway and to prevent recurring issues.

You should sand concrete before painting, as it helps remove any irregularities and pieces that stick out from the surface. This not only helps the paint look better but it prevents any unwanted water absorption.
