Pattern imprinted concrete or pressed concrete, as it is sometimes known is a technique of creating decorative, hard wearing, patterned, coloured concrete for use on driveways, patios, car parks, walkways and shopping arcades. It is a product that has been laid now across the world now for over 30 years, and is regularly used by well known companies such as McDonalds and KFC. Imprinted concrete has also been laid to vast areas of the Disney theme parks in Florida and Paris. Imprinted concrete itself is a extremely hard wearing material, but left exposed to everyday use, and the elements, without protection, damage can start to occur. When first laid installers of pattern imprinted concrete will always seal the surface with an acrylic based sealer to finish the job. This concrete sealer will protect the surface from the effects of the sun, frost, snow, vehicular use and staining. One of the great things about imprinted concrete is that routine maintenance of imprinted concrete every few years is a easy diy job. All you really need to do is just wash down the surface with a pressure washer and simply apply one or two new coats of sealer. The problem is if this re-sealing is not carried out every few years problems can start to occur. With imprinted concrete if it is left un- protected it will start to fade, and the surface of the concrete can even start to break up from the effects of snow and ice.

Hopefully your pressed concrete has not started to deteriorate in this way, but if it has, do not worry, will the help of a pressure washer, paint brush, broom, acrylic sealer and some basic repair materials I am sure you can get your driveway or patio looking fresh and new again The first thing to do is make sure that the surface has been properly cleaned, ideally with a pressure washer. Before you start resealing make sure you have enough sealer for the job and some concrete rapid hardening repair compound (available from any decent diy shop or builders merchants) if there are repairs required. For imprinted concrete that has lost colour, you will also require some coloured pigment ( used by bricklayers to colour mortar) to tint the sealer, and mask any repairs. Most areas of surface damage, and cracks can be easily repaired using the concrete repair compound. This material, when mixed with sealer will forms a fast drying paste, this can be simply troweled into defective areas using a bricklayers pointing trowel. Once the repairs are completed and the surface re-sealed, the previously damaged areas become almost undetectable.
