How to Use a Concrete Planer (Scarifier) Effectively

How-To Use A Concrete ScarifierAs a seasoned do-it-yourselfer, you’ll come across projects that require specialized equipment to get the job done right. Say you’re re-flooring a barn, workshop or warehouse building on your property, or you want to re-surface your long concrete driveway – these kinds of projects need tools that can accomplish surface preparation such as removing epoxies, elastomerics and masterplate for planing concrete and asphalt with ease. These are times when a concrete planer comes in handy.

What is a Concrete Planer?

A concrete planer is sometimes called a surface planer, milling machine or scarifier. Planers use multi-tipped cutter assemblies that rotate really fast, creating a pummeling action that chips away at a concrete surface and removes old coatings. The cutting wheels or flails are interchangeable, depending on how smooth a surface profile you need to achieve for any job.

The EDCO™ CPU12-38K Gasoline Self-Propelled Concrete Scarifier

This 800-lb concrete planer moves by itself, which cuts down on the work you’ll do to operate it, but makes cutting through and removing old concrete or asphalt quite efficient. The hydrostatic drive transmission moves the machine forward and backward while you control the speed, milling a 12-inch wide surface area with each pass to complete as much as 1,500 square feet in one hour. In addition, the hydraulic-powered drum lowers and raises itself with the touch of a lever, to a depth of up to ¼-inch into the surface.

The Edco CPU12-38K also has a cam-operated fifth wheel that allows you to reposition or change direction while the engine is still running. If you use the Standard Outrigger Axle Assembly, you can follow the contours of uneven surfaces more closely, which provides uniform surfaces removal.

Create Curb Appeal with Concrete Resurfacing

Repair Your Cracked and Eroded DrivewayToday’s the day for that do-it-yourself concrete repair project you’ve been meaning to accomplish for a while now: restoring your driveway, walkway and patio. The weather’s been cooperating all week long — there’s been no rain and temperatures are ranging between 70° and 75°F — which is not only great for your mood, but perfect for your concrete, which needs to maintain a surface temp of at least 50°F before you can repair those cracks or crumbles successfully.

No jackhammer needed. Unless your concrete has extremely wide cracking and an uneven surface, there’s no need to tear it out, repair the sub base and pour new concrete. The existing concrete can be restored to look like new with a little repair and resurfacing. Smaller cracks are relatively simple to fix, if you have these tools and products on hand:

*A quick note about power trowels: available for rent, this equipment comes with accessories for working out surface imperfections and creating a satin smooth concrete finish with ease. As always, let us know what questions you have, or if you need advice on which tools will help you effectively complete a project.

Small cracks up to a half-inch wide are the simplest to repair. Use a wire brush or chisel to scrape any debris from the crack, then spray or hose clean with water. A latex concrete patch can be injected with a caulking gun or troweled into the crack, leveled and smoothed out.

Tiny cracks up to a quarter of an inch wide should be worked with a chisel to widen slightly, enough to help hold the patch material in place. Spray the crack clean with water and let dry before applying a concrete adhesive, then a concrete patch compound. Level the patch with a trowel. Once any crack is filled, cover the repair with plastic and allow it to dry slowly before moving on to resurfacing.

If you plan to resurface your concrete, mask the expansion joints. These are the dividing areas of large slabs that help control cracking. Mask them with duct tape before applying a dressing. Mix the resurfacer with a portable mixer or electric drill fitted with a mixing paddle, pour it onto the clean slab and spread it out immediately with a trowel. Remember to texture the surface with a push broom, to create slip resistance.

Time is of the essence. Experts say is takes about one hour to resurface 60 square feet of concrete. If you use a polymer-based cement resurfacer, you’ve got less than 30 minutes to apply once water is mixed in, so prepare it in batches. The treated surface can be walked on after about two hours; wait six hours before driving a car onto a driveway. After 24 hours, protect the new surface with a clear, waterborne masonry sealer.

The 7 Step Process to Restore Your Cracked and Eroded Driveways

Cracked DrivewayMany homeowners spend a lot of time, and money, on landscaping and home improvements to give their home that “curb appeal.” But often, the first thing people notice when they come to your home is the condition of the driveway.

How Do Driveways Wither Over Time?

  • Erosion – Wind and rain can cause cracks on the surface of driveways
  • Sun Rays – The harsh effect of the sun weakens the concrete and causes expansion joints on concrete driveways.
  • Water – Annual freezing and thawing cycles as water permeates through the cracks in the concrete to settle at the base, weakening the foundation.
  • Gas, Spills and Grass – Gas and oil spills, and the growth of grass through the cracks break down the driveway even more.

Repairing the Damage

One however need not spend a fortune relaying damaged driveways. It is possible to restore driveways using driveway sealants and driveway expansion joint fillers.

Restoring your Driveway

Tools needed to restore the driveway:

The Restoring Process

  1. Fill the cracks – If the cracks are small, which is less than half an inch deep, rubberized crack fillers available in small tubes may suffice. For medium sized cracks, joint fillers are required. Squeeze the patch filler into the cracks, until it reaches the level of the driveway. Use a trowel to spread the joint filler and ensure a level surface.
  2. Repair crevices – When large cracks, gaps between the concrete blocks that constitute the driveway or crevices in the driveway are present, it is better to use grout instead. Use cement-based grout, which is a mixture of cement, fine gravel and water. Use a grout hand pump to mix the grout and make the task easy.
  3. Wait for grout to dry – Allow the grout to dry for a day or so before you proceed.
  4. Clean the driveway – Next, use a push broom to remove any dirt or debris, and wet the driveway with a garden hose lightly.
  5. Water and solvent-based sealants – Water-based sealants are environment friendly, but solvent-based sealers are more durable and better suited for heavily used driveways.
  6. Apply the sealant – Mix the water based or solvent based grout sealer, as per the manufacturer’s instructions, and apply the sealant over the driveway in thin coats. This helps the driveway resist water, oil and other contaminants. Use the push broom to spread the sealant evenly.
  7. Wait for sealant to set – Do not use the driveway until the sealant has completely set in, which may take as much as 48 hours.

If you want your driveway to have the bright look all the time, you can seal it annually. Most good seals will last two or three years, depending on the type of winter you have and how much stress is put on the asphalt from plowing or snow blowing during the winter.
