How to finish concrete
Achieving a good finish is crucial after pouring concrete if you want a durable, smooth surface. If you get the concrete finishing process wrong, it can lead to a damaged, unattractive slab.
Here, we’ll show you how to finish concrete properly to get the best results.
• Use a square shovel to spread the wet concrete.
• Get rid of excess concrete with a straight board or screed tool.
• Use a bull float to level ridges.
• Create tidy, rounded edges with an edging device.
• Use a concrete groover to joint the slab and prevent cracking.
• Unless you’ll be adding a decorative finish, use a steel trowel to produce a dense surface.
After finishing your concrete, it will need time to dry, and it can take around a month to cure completely. You can then apply a sealant to prevent stains and prolong the life of the slab.
Do’s and don’ts of concrete finishing
It can take years of training and experience to be able to get a professional concrete finish. Here are some do’s and don’ts for beginners:
• Place the concrete as near as possible to its final location.
• Avoid overhandling.
• Don’t use a round-edged shovel to spread the concrete.
• Avoid tamping high-slump concrete.
• Do the bull floating before excess moisture or bleed water appears.
