Should you wash concrete before painting it?
Yes, you should wash concrete before painting it to ensure proper adhesion and a smooth finish. Cleaning removes dirt, grease, and any existing contaminants that could interfere with the paint's bonding. Using a pressure washer or a scrub brush with a concrete cleaner can effectively prepare the surface. Allow the concrete to dry completely before applying paint for the best results.

How long should a concrete driveway cure before parking cars on it?
At least 3 days
How long should concrete cure prior to freezing temperatures?
Concrete should ideally cure for at least 7 days before exposure to freezing temperatures to ensure it develops sufficient strength and durability. During this initial curing period, the concrete should be kept moist to prevent cracking and ensure proper hydration. If freezing temperatures are expected before this period, protective measures, such as insulating blankets or heated enclosures, should be employed to safeguard the curing concrete.
How soon can concrete be sealed?
You should wait a minimum of 28 days before you seal concrete. If you pour your concrete in summer, than a minimum of 14 days is acceptable. If you seal concrete any quicker, there is a chance moisture will be trapped inside.
How do you make construction joint in raft foundation?
To create a construction joint in a raft foundation, first ensure that the concrete surface is properly prepared and cleaned to promote good bonding. Next, place a formwork or a jointing strip at the desired location, ensuring it is level and aligned with the rest of the foundation. After the initial concrete is poured and has cured sufficiently, the joint area should be treated with a bonding agent before pouring the next batch of concrete to ensure a strong bond between the two sections. Finally, monitor the joint for any potential movement or cracking as the foundation settles.
