What Is Concrete Resurfacing?
Important Point
Concrete resurfacing is the process to provide a brand new look to damaged concrete. In the process of resurfacing of concrete, a concrete coating is applied on the surface of existing concrete.
Concrete resurfacing is a time-consuming process, and it’s very much labour-intensive process so, it’s a little bit expensive also.
In this process, a special bonding agent is added to the cement mixture to get a smooth cementing surface.
Types of concrete resurfacing-
- Stamped Overlays
- Pool Deck Resurfacing
- Concrete Crack Repair
- Driveway Repair
- Resurfacing Patios
- Resurfacing Products
How to Resurface Concrete?
There are generally four steps of resurfacing concrete, those are
Step 1. Concrete Cleaning
- Concrete cleaning is done by a mechanical machine of high pressure of near about 3500 psi.
- This process is done to remove dust, algae and other hazardous materials because a cleaned surface has a better power of bonding with new materials.
Step 2. Patch Spelled Areas
- In damped concrete, resurfacer is used to fill those patches.
- Resurfaced is made by one part of water with seven-part of resurfaced in a five-gallon bucket.
- Then we need to fill up that place and smooth the area with a trowel.
Step 3. Spread the Resurfacer
- Walkway joints are filled with resurfaced.
- The resurfaced is only workable for 20 minutes.
Step 4. Trowel Operation
- Trowel operation is done to spread the resurfacer.
- The thickness of the resurfacer is ¼ to ⅛ inch.
- We need a total of six hours to use it again.
Concrete Resurfacing Material
The general materials of resurfacing concrete are
- A unique blend of Portland cement
- Sand
- Polymer modifiers
- Many other additives
This is mainly used to repair shrinkage cracks, thin repairs, etc. A fair concrete resurfacing material is defined by its flexibility, sprayable, easy for trowel operation, etc.
Here are some condition of resurfacing concrete before we purchase it from the market-
- It must be water-resistant
- It must be non-slippery
- It should be UV resistant
- It should have the ability to withstand the freeze that cycle
- It should have the ability to resistant against chemicals
- It should have the ability to overcome the heavy foot and vehicle traffic.
Now some readymade products are available in the marketplace, those are-
- Overlay Mix
- MT resurfacer
- Overlay foot mixes
- Versa-Crete resurfacer smooth mix
- Floor top STG
- Top Cap resurfacer

Concrete Repair and Resurfacing
Concrete Repair
Concrete repair is a process where we fix the problem of the concrete internally. There are several types of concrete repair techniques available, they are
- Epoxy Injection
- Routing and Sealing of Cracks
- Stitching
- Grouting Method
#1. Epoxy Injection
- Epoxy injection is a type of concrete repair process. It’s applied where the concrete cracks are not more than 0.002 inches or 0.05 mm.
- In this process, epoxy resins are entered into the cracks and exposed on the concrete surface.
- Epoxy injections are used in building cracks repairing, dams, bridges and other structures. Epoxy resin techniques need a high skill full labours.
#2. Routing and Sealing of Cracks
- Routing and sealing are applied where structural repair is not applied.
- This is applied where cracks are in the face of the concrete. Sealing is useful in a plane surface than a curved surface.
- The materials used in sealant are epoxies, urethanes, silicone, polysulphide, asphaltic material, polymer mother, etc.
#3. Stitching
- Stitching is another method of concrete repair technique.
- In this process, two holes are drilled in both sides of the concrete cracks. After that, steel bars are used to maintain the crack.
#4. Grouting Method
- In the gravity dam, wide cracks are developed in the dam’s wall.
- This process is by Portland cement grout. This method is very effective to prevent water leaks.
Concrete Resurfacing
- Concrete resurfacing is the process to provide a brand new look to damaged concrete.
- In the process of resurfacing of concrete, a concrete coating is applied on the surface of existing concrete.
- Concrete resurfacing is a time-consuming process, and it’s very much labour-intensive process so, it’s a little bit expensive also.
- In this process, a special bonding agent is added to the cement mixture to get a smooth cementing surface.

Types of Concrete Resurfacing
Types of Concrete Resurfacing are as follows
- Stamped Overlays
- Pool Deck Resurfacing
- Concrete Crack Repair
- Driveway Repair
- Resurfacing Patios
- Resurfacing Products
#1. Stamped Overlays
- Stamped overlays is a type of concrete resurfacing which gives us aesthetic beauty and texture. This is only used on existing concrete.
#2. Pool Deck Resurfacing
- This is the process to repair damaged concrete. This process is a tiny layer of cement, sand, polymer and resin.
#3. Concrete Crack Repair
- This is one of the most important processes where repair materials are poured into cracks.
#4. Driveway Repair
- Naturally driveway doesn’t need repairs, but sometimes it requires.
#5. Resurfacing Patios
- This is done by the cement-based overlay, which is durable and strong.
#6. Resurfacing Products
- In this type, there are many types of readymade resurfacing products available in the marketplace.

What Is Concrete Resurfacing
Concrete resurfacing is a thin cement based overlay that is mixed with special bonding agents. It is poured over existing concrete and adheres to create a beautiful and smooth new surface. As your new surface dries it gets stronger and more durable.
Concrete Resurfacing Material
Concrete Resurfacer is a special blend of Portland cement, sand, polymer modifiers and other additives designed to provide a shrinkage compensated repair material for making thin repairs to sound concrete which is in need of surface renewal.
Can You Resurface Concrete?
Resurfacing is a proven method of restoring the durability and appearance of dilapidated concrete by applying a thin layer of pre-blended, polymer-modified flowable mortar on top of an existing surface. Resurfacing concrete is a significantly less expensive than replacing it.
How Much Does It Cost to Resurface a Concrete Driveway?
If you have a concrete driveway, you can have it resurfaced for around $3 to $5 per square foot. If it’s too damaged or crumbly to resurface, the cost of a new concrete driveway goes for around $2 to $15 per square foot on average.
Can You Resurface a Concrete Driveway?
If sprucing up your concrete driveway is on your list of home improvement projects, consider resurfacing. Resurfacing is a great way to make your existing concrete surface look brand new. You can apply a coating directly to your concrete surface without having to rip anything out—saving time, hassle, and money.

Concrete Repair and Resurfacing
Concrete repair:
The process of concrete repair typically involves identifying the cause of the damage, cleaning and preparing the surface, and applying a concrete repair material to fill in the damaged area. The repair material may be a cementitious mix, epoxy, or other specialized material depending on the type and severity of the damage.
Concrete resurfacing:
Concrete resurfacing involves applying a thin layer of concrete or concrete-like material to an existing concrete surface. This is done to improve the appearance and durability of the surface, and to protect it from future damage.
