Cover The Concrete With Plastic Sheets

One of the most effective materials to guard against rain is plastic sheeting visqueen.

Cover the concrete with plastic sheets.

Should you cover concrete with plastic to help curing. Adverse weather conditions such as rain snow or freezing temperatures often make it necessary to protect concrete by covering it. Curing concrete with plastic sheeting requires covering all exposed areas of the concrete as soon as possible without damaging the concrete finish. Use bricks boulders or stakes to hold the plastic in place and keep small animals out.

Plastic sheets should be firmly placed on the concrete surface and all edges and corners must be kept well covered. A plastic polyethylene covering retains moisture in the concrete and improves temperature control. In cold weather plastic clad concrete curing blankets are often used to protect the surface from snow and insulate the concrete from freezing. Another method to prevent discoloration is to place dry straw directly onto the concrete then put the plastic on top of it.

Curing compounds are chemical products usually sprayed directly over the concrete surface and allowing it to dry. Lap joint should be minimum 300 mm between the sheets. When plastic sheeting is used over flat surfaces such as pavements or slabs it should extend beyond the edges of the slab by a length of at least twice the thickness of the slab. It is a common misconception that concrete cures by drying out like a pie crust that hardens as it.

The sheets should be in close contact. However there are some precautions need to be exercised when this method is used. When plastic sheeting is used over flat surfaces such as pavements or slabs it should extend beyond the edges of the slab by a length of at least twice the thickness of the slab.
