Concrete Resurfacing

What Is 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-

  • Stamped Overlays
  • Pool Deck Resurfacing
  • Concrete Crack Repair
  • Driveway Repair
  • Resurfacing Patios
  • Resurfacing Products

How to Resurface Concrete

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

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

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.

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.

Short Note

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.
