Sand the Surface and Wash the Concrete Finish by fine-tuning with light sandpaper, until the surface is perfectly smooth. We recommend using a hand planer to smooth and compact the surface. If the concrete dries a lot then we recommend that you add water to the surface, this will help you give it a good finish.
What is smooth concrete?
The most basic type of concrete finish is a smooth surface created through the use of screeds and trowels. Immediately after concrete has been placed in forms, concrete finishers utilize a screed to level out the concrete surface.
What is the strongest concrete mix ratio?
A strong concrete mix would be something like 1:3:5 (Cement, Sand, Coarse Gravel). In this case, both the sand and gravel are the aggregate. In pre-mix concrete, the aggregate is already mixed with the cement.
Is it cheaper to mix your own concrete?
One of the least expensive ways to get concrete is to mix your own. You can buy bags of the mix from a home improvement store. Typically, you only have to add water for it to be ready to pour. Otherwise, you risk getting a weaker concrete once it cures, which could lead to cracks or crumbles within a couple of years.
What is the top layer of concrete called?
Concrete spalling, also referred to as scaling, occurs when the top layer of concrete – which is about 1/16th of an inch thick – chips, flakes or peels away. Scaling five millimeters or deeper can cause the aggregate to appear.
Why do we Broom concrete?
Broom finished concrete is popular for patios, driveways and more. Sometimes called brushed concrete, a broom is used to create a slip-resistant texture on the surface of the concrete. Broom finished thin overlays add skid resistance and upgrade a deteriorating concrete surface.
What are the different concrete defects?
Different types of defects in concrete structures can be cracking, crazing, blistering, delamination, dusting, curling, efflorescence, scaling and spalling. These defects can be due to various reasons or causes.
How do you make a concrete floor smooth and shiny?

Class 1 finishes should generally be specified only for selected small elements contained in a single pour, and not for entire building facades, since they are costly to achieve and difficult over large areas.
Which is the weakest concrete?

Can you mix Portland cement with just water?
Cement mixed with water alone creates a grout which can be used for repairing any damage on concrete structures. This cement-based grout mix is also used in situations where normal concrete won’t work, such as underwater concreting.
What happens if you put too much cement in concrete?
Since major force transfer in a concrete/mortar matrix is from sand-sand interaction, excess cement will turn the mortar very brittle since cement particles cannot transfer normal contact force – they are good at providing shear strength.
What is poor man’s concrete?

What is concrete called before it hardens?
Portland cement is a type of hydraulic cement, which means that when water is added through a process called hydration, it starts the chemical reaction that causes the cement to harden and set, holding the aggregates together in a rocklike mixture—concrete.
How do you fix a bad broom on concrete?
There are two things you can do fix the rough finish. One is, you could grind or polish the surface which would remove the rough broom finish and smooth the surface of the concrete. Some of the aggregate would be exposed giving you a nice smooth decorative look to your sidewalk and patio.
