FAQs about concrete sealers

Why Does My Concrete Floor Sweat?

Causes of Surface Dampness on Concrete Slabs and Garage Floors:

Humidity—warm and humid air condenses into surface moisture when it comes into contact with the cool surface of your concrete floor or slab.

Faulty/Missing Vapor Barrier—moisture from the ground can seep up and through the concrete.

Bone Dry's Etch-a-Crete is a great solution to open pores in a concrete slab. Moisture absorbs into the concrete instead of beading up on the surface.

What is the Source of Your Concrete Dampness?

How to fix concrete floor sweating

A Simple Test to Find the Source of Concrete Moisture:

To discover whether your concrete moisture is caused by humidity or vapor barrier issues—

  • Tape a 2 x 2 foot square of plastic sheeting onto dry concrete
  • Wait 48 hours at minimum
  • Remove plastic and check for moisture condensation

If there’s beaded moisture: a faulty or missing vapor barrier is a likely culprit—Bone Dry Products is your best solution
No beaded moisture: your issues are likely related to humidity—improving ventilation and controlling temperature will fix humidity problems

Why Does Concrete Crack?

What are the Main Causes of Cracking and Breakage in Concrete Floors?How to Prevent Concrete Cracks

Most common factors of concrete cracks include, but aren’t limited to:

  1. Water evaporating too quickly from the surface of the concrete – moisture is one of the leading factors of concrete floors cracking or breaking. Moisture mitigation products from Bone Dry are the best way of preventing more cracking or breakage happening in your concrete floor!

  2. Poorly-compacted soil underneath concrete causes shifting – soil beneath concrete floors has the potential to shift around and move over time, or water pooling underground can either raise or lower the land beneath the concrete. 

  3. Drying concrete shrinking due to temperature changes – a wide range of temperatures and weather patterns can affect the way cement dries

  4. Corrosion of steel underneath concrete – Oxidation of reinforcing steel bars beneath the concrete can cause cracks to form in the cement.

  5. Pressure from exceeding the weight limit – cracks can form in concrete due to having too much weight on it for extended amounts of time. Cars generally aren’t heavy enough to form cracks, but larger vehicles like semi-trucks can cause breakage in concrete surfaces if they cause pressure for a long enough time.

How Do You Prevent Concrete Cracking?

Cracks in concrete can happen for a variety of reasons, but exposure to heavy weights, moisture penetration, and a wide range of temperatures are the leading causes of it. There are so many factors to consider for when cracks occur in concrete, but the best way to prevent it is to take every possible precautionary measure when pouring it. Some of the precautions to take include:

  • Structural design – Contraction, expansion, and isolation joints need to be constructed at reasonable intervals beneath reinforced concrete. Proper width and spacing is required to making concrete flooring as strong as possible.

  • Mixing materials – Cement mixtures are strongest when not contaminated with foreign materials, like clay or dirt. A larger amount of aggregate in the cement plays an important role in crack prevention, and because of that, shrinkage can be reduced with the smaller amount of water in the concrete mixture.

  • Placement – A properly compacted subgrade (the ground beneath where the cement is being poured) is important for preventing cracks occurring in concrete. A careful inspection of the subgrade, as well as an evaluation of the climate in which the cement is being poured, is essential in preventing cracks forming.

  • Finishing and curing – Curing cement as quickly as possible helps make it stronger and reduce the risk of cracking. A dehumidifier can be used to encourage concrete to dry more quickly since it can reduce the dew point of the air surrounding the cement.

Want to Prevent Cracking? Bone Dry Products Can Help!

Bone Dry concrete moisture mitigation products are water-based, penetrating sealers which produce a waterproof barrier deep within your concrete floor, helping you prevent cracking and breakage within the cement. Epoxies and other sealants aren’t as versatile as Bone Dry sealers, and can be up to four times as expensive – Bone Dry products are much more affordable and easy to apply.

How does BONE DRY seal concrete?

Bone Dry penetrates below the surface of the concrete slab using a blend of products to react, solidify, and fill the pores below the surface of the concrete. This creates a barrier beneath the surface of the slab while the concrete surface remains unchanged. The result is a sealed concrete slab which protects surface coatings from concrete moisture and a concrete surface which allows surface coatings to bond as they normally would to any concrete slab.  

Why does BONE DRY work better than other so-called penetrating sealers?

The secret to effectively sealing concrete with any silicate based material is to get the silicate to access as much of the free lime and alkali present within all concrete.

How is BONE DRY applied?

For large areas, low pressure airless backpack spray equipment is very efficient. For medium sized jobs, a simple hand pumped garden type sprayer can be used. Bone Dry can also be applied with a brush or roller in confined areas.

How long do I have to wait before I can walk on the concrete slab after BONE DRY has been applied?

You can work on the slab almost immediately. This creates minimal downtime on your job. Be careful as the concrete will be slippery.

Are there any temperature minimums or maximums for the concrete?

Yes. Bone Dry should be applied to clean, damp concrete at temperatures ranging from above freezing (40 degrees recommended) up to a maximum of about 90 degrees for a minimum 24 hour period.

Is BONE DRY compatible with all adhesives and skim coatings for both carpet VCT and wood floor adhesives?

Yes, Bone Dry is compatible with all types of skim coatings and adhesives.

How soon after the concrete is poured/finished may your product be applied?

There are many variables when applying Bone Dry to green concrete. Please contact us to discuss your project.

What effect does temperature play with respect to how well the Bone Dry will work?

As sealing concrete with Bone Dry is a chemical reaction, one could expect that this process would be retarded by cold and freezing temperatures. Although the reaction may take somewhat longer in cold temperatures, the resultant seal will be every bit as effective as when the material is applied during average temperatures.

Will the product work faster or create a dryer slab if the temperature is above a certain threshold?

"Room temperature" would be ideal and the product will work a little faster under these conditions; but no, the concrete will not be dryer. The Bone Dry has a voracious affinity for the calcium hydroxide and will find it regardless of the temperature, aside from freezing, as we explained above.

How is BONE DRY packaged?

Bone Dry products are packaged in one and five gallon pails and 55 gallon drums. 

Can Mold Grow on Concrete?

Moisture Can Cause Mold and Bacteria to Grow on Concrete Substrates

Mold growing in and around homes is a serious problem for many people. It can slowly overtake walls and floors as well as trigger allergy symptoms in people who spend too much time around it. The bacteria that mold produces can also degrade concrete floors, compromising its strength and durability. Mold won't feed on the concrete itself, but rather on the moisture, algae, salt, pollen, dirt, dust, and other particles trapped inside the concrete substrates.

Can Mold Grow on Concrete

The conditions which allow mold to grow in concrete floors include:

  • Humid weather – concrete itself isn’t an insulator, so airborne moisture will condense on the concrete surface and cause mold to grow there. Environments with a high relative humidity (RH) tend to grow more mold and bacteria.
  • Ground water intrusion – concrete floors in basements and garage floors may become saturated with ground water. Without proper drainage, these floors can collect moisture and become a breeding ground for mold and bacteria.
  • Bad ventilation – when it comes to indoor concrete substrates, a badly ventilated room can cause moisture to condense and mold to grow on the concrete floor. Particularly during the winter, wet cold air in the home can hold more moisture than warm air.

Prevent Mold Growth with Bone Dry Products 

Don’t let excess moisture in concrete floors lead to mold and bacterial growth – get Bone Dry for the best effective penetrating sealers applied to your concrete floors! Moisture mitigation is important when you want your concrete floor to be finished with vinyl, paint, wood, VCT, or carpeting.
