Concrete Joint Sealer vs. Concrete Joint Filler

Friday, February 20th, 2015

When it comes to concrete joints, is there any difference between sealers and fillers? You might be surprised to learn that yes, there is a difference. These two masonry tools are used for different applications in masonry repair, but they’re both important components of joint repair. This week, we’ll talk about the differences between sealer and filler, and how they’re used in masonry repair.

Concrete Sealer

Concrete sealer is soft. This allows it to expand and contract in the joint as the concrete expands and contracts naturally due to temperature changes. The sealer prevents water, ice, dirt, and other from debris from getting into the joint, where it can cause water damage, or freeze and causing cracking. Sealer also prevents intrusion from under the concrete slab.

The best sealers have the following characteristics:

  • The ability to create a strong bond to the concrete.
  • Impermeability, in order to prevent the ingress of water.
  • The ability to handle repeated expansion and contraction.

 

Sealer should be applied once the concrete slab has undergone its natural shrinkage. Sealers will need to be checked at least once annually and assessed. If the sealer has degraded, it will be necessary to reseal in order to prevent damage.

Concrete Filler

Concrete filler on the other hand is hard. The goal of filler is to support the edge of the joint when it needs to bear a lot of weight. Note that filler is only used with saw-cut joints. Joints with a rounded tooled edge cannot use filler.

Fillers, like sealers, should only be applied after the concrete slab has shrunk. This can take up to a year, but fillers will not be effective if applied before this process is complete. Fillers should also be inspected annually to determine if they need to be reapplied.

Taking Care of Concrete in the Winter

Wednesday, January 28th, 2015

Winter weather is here in Baltimore, which means rain, snow, ice, wind, and general poor weather. This weather can damage concrete due to the freeze thaw cycle and expansion and contraction. Learn more about the effects of winter weather on concrete, and how to protect your concrete in Baltimore.

Concrete Problems in the Winter

Freeze Thaw Cycle

The freeze thaw cycle occurs continuously as water freezes and melts. When water freezes, it expands, and when it melts, it contracts. This means that if there are any cracks in the concrete, water in them will expand when it freezes, making the crack bigger. The bigger crack lets more water in, this water freezes, and the crack gets bigger and bigger all winter. The greater the number of freeze thaw cycles, the worse this problem becomes.

Salt

Salt is not kind to concrete. There are several things that salt does to concrete.

  • Salt is slightly acidic. This lowers the pH in concrete, which increases the size of the pores in concrete. This lets water into the pores, the water freezes, and cracks develop.
  • Salt attracts and retains water in the pores of concrete because it is hygroscopic. This creates another problem known as slapping, where the surface of the concrete chips and flakes.
  • Salt accelerates carbonation of concrete, which reduces its pH.
  • Salt introduces chlorides into concrete, which corrodes steel reinforcements in the concrete.

How to Take Care of Concrete in the Winter

Seal It

This tip is technically for before winter, but using a protective coat of sealant on concrete will actively protect it from salt and ice in the winter. Seal concrete in the fall before winter weather for best results.

Remove Snow and Ice

When it snows, remove snow and ice from concrete surfaces as soon as possible.

Use Sand, Not Salt

Lay down sand on snowy walkways, not salt. Sand won’t help melt the ice, but it will give you traction, and it won’t hurt the concrete.

Avoid Deicers

Deicing chemicals are sometimes used to melt snow and ice. While they can do a good job, they’re harmful to concrete. If you do use deicers, use them only according to the manufacturer’s directions.

Concrete Repair Contractor in Baltimore: Consolidated Coatings

Wednesday, December 3rd, 2014

If you’re in need of a concrete repair contractor in Baltimore, now is the time to act. With the winter coming up fast, it’s a good idea to do your concrete and masonry repair work now before the ice of winter makes things worse.

Ice: Concrete’s Worst Enemy

In the winter, your concrete and masonry can be severely damaged by ice. Water gets into cracks in the masonry, and when it freezes it has to expand. So what does it do? It makes the crack bigger in order to expand. It might seem surprising that concrete can be moved by just a little frozen water, but water yields to nothing if it becomes frozen. It will expand even if it means breaking concrete to do so.

So what ends up happening is throughout the winter, the many freeze thaw cycles cause those small cracks in your concrete and masonry to get bigger and bigger, until suddenly they’re not such small cracks anymore. They also start to become less of a cosmetic problem and more of a structural problem. The end result is that the concrete you started the winter with will not look like the concrete you end the winter with. However, if you enlist the help of a concrete repair contractor in Baltimore, you won’t have this problem.

Consolidated Coatings: Your Concrete Repair Contractor in Baltimore

Concrete develops cracks naturally over time. But with regular concrete repair and maintenance, these cracks won’t turn into big problems. Take care of your concrete, and it will be well-prepared for a longer winter. A little preventative maintenance now goes a long way, and could save you from having to do some major repairs in the spring. If you’re looking for a concrete repair contractor in Baltimore, you can trust Consolidated Coatings. Contact us today for more information.

Loxon Concrete and Masonry Primer/Sealer

This acrylic concrete and masonry primer is used to seal and condition porous above-grade masonry surfaces. It can be used on everything from concrete and plaster to brick, stucco, fiber cement siding, and EIFS exterior insulated siding. Other advantages include:

  • It tolerates the high pH common in new masonry.
  • Ensures a uniform look.
  • Masks pinholes and surface imperfections.
  • Prevents peeling caused by alkali salt damage.
  • Fast curing saves time and money.
  • Long lasting finish.

 

Loxon Topcoat

This exterior acrylic coating is used for exterior above-grade masonry surfaces. It offers a high performance protection for concrete, cement composition panels, concrete block, brick, and stucco.

What’s the Science Behind My Concrete Walkway?

Friday, October 10th, 2014

concrete

You walk on it, your kids draw with chalk on it, maybe you’ve put your handprints in it before, but what is concrete? It’s something that we don’t think much about because we see it every day. We take concrete for granted, but have you ever considered what it’s made out of? It’s liquid at one point, and then hardens forever. How does that happen? We’re here to tell you the science behind your walkway!

You might use the words “cement” and “concrete” interchangeably. However, the two are actually very different. Cement is actually begins as a powdered material, and later becomes concrete when combined with other elements. Concrete is the hardened material that you are familiar with on your sidewalks or walkways.

So what is concrete composed of?

  1. Cement. This is actually a powdered material made up of limestone and clay that chemically reacts with water and different aggregates to form the thick liquid that is poured into place, and later hardens to become concrete.
  2. Water. This is needed to allow the cement to react in the way it’s supposed to. Water is necessary for hydration, a chemical process that bonds molecules together. This process is what makes the cement mixture harden into concrete. It is also important to control the water-to-cement ratio. For example, if the ratio of water is lower, there will be less permeability within the concrete. Less permeability, or liquidity within the cement mixture means greater strength in the final concrete product.
  3. Aggregates. Another word for aggregates is “collections”, or  “combinations”. Aggregates within concrete include sand, gravel, or crushed stone. These aggregates compose most of the concrete and are bound together by the cement and water mixture. Aggregates can be very fine, or can be large and unique, allowing for a decorative pavement. 

So now you know the basics of the composition of concrete! Next time you’re walking along the sidewalk with a friend, impress them with your newfound knowledge. If you’re looking into laying cement on your property, contact the professionals at Consolidated Coatings Incorporated. We’ll give you all the information you need about what type of concrete is best.

Why Does Concrete Crack?

Wednesday, June 25th, 2014

Concrete cracks are a common sight in old concrete found outdoors which has been subjected to years of freeze thaw cycles and weather. Indoors, concrete is protected from the elements, but not from poor installation, which can cause concrete to crack. In general, the two leading causes of concrete cracking are the elements, and improper installation.

Why Does Concrete Crack?

Exposure to the Elements

All outdoor concrete is exposed to the elements, and this exposure results in the contraction of concrete during times of cold weather and its expansion during times of hot weather. This flux creates small cracks, which grow over time and especially during freeze thaw cycles, when water gets in and freezes, which expands the cracks.

There are several ways to mitigate cracks in concrete as a result of the elements. First, proper installation goes a long way in preventing cracks. Second, use sand instead of salt when there is ice or snow on concrete surfaces. The sand does not accelerate the freeze thaw cycle like salt does, which makes it easier on the concrete. Third, proper maintenance can help prevent cracking or repair existing cracks. An acrylic silicone solvent based sealer helps protect concrete from cracks, and epoxy injections can seal cracks and prevent them from growing.

Poor Installation

Another leading cause of concrete cracks is poor installation by a contractor that is unfamiliar with proper concrete installation practices. Often, contractors will add too much water to the mix. While this makes it easier to install, it also causes it to shrink and pull apart as it dries. Contractors may also use the wrong strength concrete for the job or neglect to install control joints correctly. Improper curing is also a culprit of concrete cracking, as the concrete dries too fast and water is not added at the right times. A skilled concrete contractor knows how to properly install concrete surfaces to minimize the risk of cracks.
