Concrete Maintenance Basics

As concrete ages, many factors play a role in the internal breakdown of the molecular bond. As everything in our universe decays, it breaks apart at the molecular level and concrete is no different. With the use of several maintenance techniques, a poured concrete structure that is open to the elements will remain intact for decades to come.

Cleaning Concrete

One fact about cleaning concrete that is often misunderstood is the pressure washer. Many homeowners rent or purchase pressure washing equipment, planning to clean the algae or stains from the concrete. The process is repeated over and over with the same effect. Every six months you have to pressure wash it again. This is a case of wasted money and time when the best solution for cleaning dirty concrete is to pressure wash it, etch and stain it, sealing it forever from invasive chemicals, nature and erosion.

After a good pressure washing from a quality pressure washer, allow it to dry 24 hours before proceeding with the etching. Using an etching formula like Krud Kutter is a safe alternative to muratic acid and is less toxic to handle. With a pair of rubber gloves on, mix the etcher as directed and scrub onto the concrete using a stiff bristled brush.

Seal Coats

A seal coat is a protective paint or stain that is applied to the concrete, changing its upper layer into a protective composite coating. Typically the concrete paint is colored, changing the appearance of the concrete, but clear coats can be used as well. Aggregates like sand or fine gravel is added to the mix providing a firm anti-slip surface concrete sealer, even when wet. Epoxy semi-gloss concrete stain can be added to interior concrete slabs for oil-free and stain proof finishes perfect for mechanics shops, just like in world class car showrooms around the world.

Clear coats and other concrete stains are easy to apply. Using a heavy nap roller cover and paint roller, spread on the concrete sealer just like you would paint a wall. Keep paint lines down by continually keeping plenty of paint on the roller (AKA loading the roller) and reworking areas. A second coat is often needed on porous concrete to correct holidays.

Yearly Maintenance

Every year after the concrete has been properly sealed, a simple cleaning with an oxygenated bleach product is sufficient. If any concrete stain has peeled up, discolored, blistered or flaked, the area should be pressure washed and allowed to dry for 48 hours prior to a heavy retching and resealing with the concrete stain.
