New Concrete Care
The following are tips relating to freshly poured concrete in the first few months of its life.
- “Guard” your concrete after the finishers leave to avoid footprints of the rash or naive, paw prints of the oblivious and seekers of immortality (who may wish to write on or otherwise mark the surface of your concrete).
- although our installers will install caution tape to alert people to your new project, it will be vulnerable for a number of hours after it has been finished. The amount of time can vary considerably depending on the temperature. In cool temperatures the hardening will take much longer.
- We do keep an “eye on the sky” and cover your project if we think it is necessary, but weather changes quickly, Do not hesitate to call us if we are not on site and you are concerned.
- Make arrangements for your pets
- Do not walk on the new concrete for at least 24 hours to avoid scuffs and scratches. Although you may not “sink in” a scratch early on can remain visible for a long time.
- wait longer if the weather is cool
- it is best to wait until the colour of the concrete starts to turn “white” before walking on it.
- Do not drive on your new concrete for at least 2 weeks or longer if the weather is cool. Concrete gains strength slowly. Concrete is not expected to reach its full design strength for at least 28 days. Although this can be inconvenient the weight of a vehicle is likely to cause unwanted cracks if the concrete is not strong enough.
- Avoid the use of deicing chemicals if at all possible. They are hard on the environment but they are also hard on your concrete. They are known to increase the likelihood of surface spalling. This is especially true for the first year and even more so if the project was completed late in the season.
- clear snow promptly before it packs or turns to ice.
- Use sand on icy areas
- Avoid having downspouts draining on or around your concrete to avoid staining and freeze thaw damage.
- Avoid oil stains by keeping vehicle seals in good condition. Concrete is porous so oil and other stains penetrate deeply and are difficult or impossible to remove completely.
- Sealers protect the surface to some extent by reducing the penetration of water and corrosive chemicals.
- Concrete enhances the look of exposed aggregate and pattern stamped concrete. The colors are brightened and a gloss is introduced.
- Most concrete mixes are designed to perform well without requiring sealing, but sealer does afford some additional protection.
- Resealing your exposed or patterned is usually done every few years. You will be amazed how the look of your project will be renewed!
- Resealing is something you can do yourself, if you so desire. You will require a pressure washer, a paint roller and brush as well as personal protective equipment. Ask us about a compatible product that you can use.
Sealing and resealing
Concrete is sealed for two main reasons, protection of the surface and enhancement of the look.
