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.

Why Does Paint Peel?

Wednesday, June 18th, 2014

Paint that is peeling, blistering, bubbling, or chipping, is unsightly and can cause a lot of mess as it spreads and paint falls off the wall. There are many reasons paint can peel, some of which such as proper installation, can be controlled. Others, such as the weather, cannot. Though peeling paint does not have any implications as far as structural integrity is concerned, it still looks unprofessional, and can be difficult to fix on your own. If you need professional painting services in Baltimore to fix your peeling walls or to paint a new structure, Consolidated Coatings has the experience and skills to paint your structure right the first time so it won’t peel or chip in the future. With that being said, here are a few reasons why paint peels.

 

Why Does Paint Peel?

Water Damage

Water damage can spell disaster for a lot of structural components, including paint. Moisture impedes paint’s ability to bond to the surface on which it was painted, and will inevitably cause it to peel.

Too Many Coats

Walls that have been painted many times may have problems with paint peeling. As the layers of paint accumulate and become heavier, their ability to hold new layers is weakened. Paint may start to peel when there are simply too many coats on the wall.

Weather

Weather can be a factor in paint chipping, especially in areas that are not conditioned by HVAC. Fluctuations in temperature between hot and cold cause the paint to expand and contract much like pavement, which causes the paint to buckle and chip.

Improper Painting

If the paint was applied improperly in the first place, the evidence of this will manifest in the form of chips and peels. The surface may not have been properly cleaned before the paint was applied, or it may have been uneven, both of which cause paint to peel over time. Another possibility was that the wrong primer or paint was used, or that an incompatible coat was applied over an old one, for example, latex-based paint over oil-based paint.

Tips for Cleaning Up After a Flood

Tuesday, June 10th, 2014

If there’s one word for the clean up process of a flooded building, it is “extensive.” Floods can cause all kinds of water damage to buildings both in the short and long term, which is why it’s important to start dealing with the effects of a flood as soon as it is safe to do so. If your building has recently flooded, here are a few tips for cleaning up.

Tips for Cleaning Up After a Flood

 

Safety First

Before you even enter the building, make sure you take the proper steps to protect yourself. The power to the building should be shut off and an analysis of its structural integrity made before you enter. You’ll also want to wear gear to protect yourself, as the water may be contaminated with bacteria, pesticides, oil, and other substances picked up from the runoff. Waders, rubber gloves, eye protection, and an organic vapor respirator are all advised. Once inside, open windows to ventilate and use a portable fan if possible.

 

Look for Saturation

Find the water line by removing portions of wet walls and insulation. Now measure 15 to 20 inches above it. Everything below this line should be removed and disposed of. If the flooring is removable, remove it and look for saturation underneath.

 

Dry, Discard and Clean

The quicker you begin the drying process the better, as mold can begin to form quickly. Keep the building well ventilated, with air moving and temperatures moderate. Any porous items should be disposed of, as they’ve been contaminated. Clothing, however, can be saved with a soak in detergent and hot water. Clean wall cavities and exposed durable materials with detergent and pressure washing.

 

If you need help cleaning up after a flood, the best course of action is to enlist the services of a building restoration company that knows how to restore previously flooded buildings, ensure they are safe to occupy, and prevent them from suffering future water damage with building waterproofing services. For building restoration from water damage, and waterproofing and protection, contact Considated Coatings in Baltimore today.

The Many Layers of EIFS

Wednesday, June 4th, 2014

EIFS, which stands for Exterior Insulation and Finish System, is a method of cladding exterior walls that offers several benefits to structures, including drainage and temperature regulation indoors. The system consists of several layers of materials that provide insulation and drainage, as well as reinforcing layers and exterior finishes. These layers can vary depending on the manufacturer, which may have their own proprietary system, but generally follow the following schema.

The Many Layers of EIFS

Substrate – The most interior layer, which may be covered by a water-resistant barrier.

Adhesive – The adhesive joins the substrate and the insulation board, and also provides a drainage plane to move moisture down and out of the structure.

Insulation board – The insulation board provides temperature regulation for the structure’s indoors. Usually made from expanded polystyrene.

Base Coat/Mesh – The base coat rests on top of the insulation, and is water resistant to act as a weather barrier. It is also reinforced with a glass-fiber mesh that is embedded in this layer.

Finish Coat – The final coat of the EIFS system, the finish is what is visible on the building’s exterior. “A finish coat typically uses colorfast and crack-resistant acrylic co-polymer technology.

 

According to the EIFS Industry Members association, choosing EIFS confers several advantages on a structure. EIFS offers excellent thermal and moisture control, which translates into energy savings and a longer lifespan for the cladding and the structure. EIFS also offers improved indoor air quality and continuous insulation. Color and style options for EIFS are numerous, which makes them great for cladding any structure.
