How do you use top cast?
Before starting your project always prepare small test panels to determine the suitable grade and etch. Apply top cast uniformly to the wet concrete after the evaporation of the initial bleed.
How do I remove top cast?
Early removal of Top-Cast can be accomplished by the use a stiff bristle brush/broom and a garden hose. Wash until clear water runs from the surface. The Top-Cast surface may also be removed using a buffer with an 80 grit carbide bristle brush with water. Follow up with a power washer to rinse.
What are the different concrete finishes?

- Troweled Finish.
- Broom Finish.
- Stamped Concrete Finish.
- Salt Finish.
- Exposed Aggregate Finish.

- Polished Finish.
- Colored Finish.
What is broom finish concrete?
Broom Finish concrete is concrete finished by dragging a horsehair broom, or something similar, over its wet surface. Brushing the concrete makes for a textured surface with small, but noticeable grooves. Broom Finish concrete has been the preferred utilitarian texture for exterior concrete for decades.
What is a concrete retarder?
Retarding admixtures are used to slow the rate of setting of concrete. By slowing the initial setting time, the concrete mixture can stay in its fresh mix state longer before it gets to its hardened form. Use of retarders is beneficial for: Complex concrete placement or grouting. Special architectural surface finish.
Who is top cast?
Top-Cast® is a water-based, top-surface retarder which does not require covering with plastic for protection. It is available in 11 depths of etch, each one color and number coded for safety and convenience.
What is the most durable concrete finish?
Epoxy Painted Concrete Floors
Epoxy Painted Concrete Floors
Epoxy is the most durable concrete finish and can be poured into cracks and crevices to help level the surface. But epoxy also is available in a variety of colors, allowing you to create unique hues and designs on your floor so you can even make a concrete floor look pretty.
What are the 4 types of concrete?
Let’s take a quick look at the most common types of concrete and what they are used for:
- Reinforced Concrete.
- Lightweight Concrete.
- High-Strength Concrete.
- High-Performance Concrete.
- Precast Concrete.
What happens if you broom concrete too early?
Groove depths also are a function of timing or how hard the surface is when broomed and downward pressure is placed on the broom. Brooming too early can create deep grooves and an irregular and rough surface; whereas, brooming too late may create very shallow grooves.
How long do you leave concrete before brushing?
When it comes to brooming, timing is critical—brush too early and the surface will be weak, brush too late and there won’t be enough texture. It must be done while the slab is still soft, but after the bleed water has dissipated. Depending on the weather, this can take anywhere from 20 minutes to 4 hours.
What happens if you put sugar in concrete?
Sugar increases the setting time of cement up to 1.33 hrs at dosage level of 0.06% by wt of cement. There will be no effect on workability, compaction by the use of sugar as admixture in concrete. Higher long-term compressive strength is achieved in concrete by the use of sugar as admixture.
Does plasticizer weaken concrete?
Now and again, plasticizers are utilized to diminish the concrete substance and warmth of hydration in mass cement.
Which caste is top in India?
A hierarchical system wherein generally the Brahmins were at the head of the hierarchy, but this hierarchy was disputed in some cases. In various linguistic areas, hundreds of castes had a gradation generally acknowledged by everyone.
What is the best sealer to use on concrete?

What Sheen is best for concrete floors?
A matte finish gives concrete floors some light reflectivity, yet won’t overpower the area. If you’re after more subtlety and warmth, this type of finish is your best choice.
What is the strongest concrete?
Ultra-High Performance Concrete (UHPC) is a cementitious, concrete material that has a minimum specified compressive strength of 17,000 pounds per square inch (120 MPa) with specified durability, tensile ductility and toughness requirements; fibers are generally included in the mixture to achieve specified requirements …
What is the strongest concrete mix?
C40 concrete is the strongest and most durable mix and for good reason townhomes for sale san diego. It can handle almost any abuse, including withstanding corrosion, making it ideal for farm-based and laboratory environments.
How long after pouring concrete can you finish it?
You can use your concrete for light foot traffic 3 to 4 days after placement, and you can drive and park on your concrete after 5 to 7 days, but curing isn’t complete until the 28 day mark. Once the concrete is fully cured, apply a protective sealer to prevent stains and prolong the life of your slab.
Do I need to wet new concrete?
ANSWER: Keeping concrete moist helps the curing process. Concrete hardens as a result of a chemical reaction, called hydration, between cement and water, not because it dries. The hardening, or curing, continues as long as moisture remains in the concrete.
What happens if you dont water concrete?
Concrete that is not moist-cured at all dries too rapidly, and reaches less than half its potential design strength. It will also have a greater number of shrinkage cracks.
Can you trowel concrete too much?
If you haven’t done this before or only done it a few times you are likely to make two mistakes; troweling too soon and troweling too much. Both of these have the effect of pulling fines and water to the surface. This can lead to a weakened surface, tiny cracks and a white dusty surface.
Does vinegar dissolve concrete?
Will Vinegar Damage Concrete? Cleaning concrete with vinegar will not damage it! However, saturating concrete for an extended period will damage the cement that binds concrete together. Over time, vinegar erodes the concrete itself, so be careful.
What happens if salt is added to concrete?
The answer is yes, salt does indirectly damage your concrete driveways, patios and sidewalks. Bumps and potholes don’t just appear due to regular wear and tear – salt damages concrete over time by causing corrosion to occur under the surface, leading to discolored, cracked and crumbling concrete.
