What is a “Pop-out” in your Garage Floor?

by Joe Sheehan

October 15, 2010

By definition a “pop-out,” in concrete, is the breaking away of the concrete surface leaving a “shallow, conical, depression in the surface.” In Minnesota, it’s usually caused by freeze / thaw cycles, aggregate expansion (a stone in the concrete slab that may be close to the surface), and/or the constant salt attack (think DOT: winter road salts).

Scenario: The typical home owner is naturally concerned about these “pop-outs” in their concrete. They attract dirt, moisture, water, and every year they progressively worsen. Eventually, the owner goes to a store and buys repair material, such as caulk or bagged cement, with the anticipation of it working.

Question: Should you apply a garage coating over a repaired “pop-out?”

Answer: No. The repairs must be removed and replaced. Once a coating is applied, the concrete slab will equalize with moisture (RH – Relative humidity). Moisture over time will deteriorate the “do-it-yourself” repair at the bond point and “pop-out” again.

Question: How should they be repaired and what is the cost?

Answer: All of our repairs are based off industry standards, recommendations, processes and procedures – in layman’s terms, we jackhammer all the damage and repairs out, and fill them with material that is guaranteed to perform and last. The cost can vary based on damage from nothing to $100’s – pending on how much labor and material is required to bring the surface to our standards prior to coating. Every floor is different.

Conclusion: If the old repairs are left in, and the contractor coats over the repair, the failure (which is inevitable) is now the responsibility of the home owner – therefore nullifying any warranty the coating has.

At G-F One Coatings we remove ALL previous repairs, whether they are poured repairs, cement repairs, or caulked (do-it-yourself repairs).

Through years of experience, we have found that if our processes and procedures for repairing “pop-outs” are not properly executed, the failure factor will come to play and the floor will not last. By not following these guidelines, the garage floor coating is simply put at risk.

Epoxy Floors, Failure and Removal

by Joe Sheehan

October 12, 2010

In the past few years, we’ve experienced a sharp increase in the demand to remove failed epoxy garage floors in the metro area. After asking each and every one of our customers about why their previous floor failed – we got a variety of responses. Some of the floors lasted years, some of them months and some of them just days. Some of them blamed their applicators, some of them blamed the product. Some of them even blamed the neighbor who told them to do it in the first place. Regardless of who did it, or why it happen, one thing was clear – each epoxy floor had separated from the garage surface. The coating simply delaminated from the concrete.

On a positive note: each of the customers found value in having a garage coating. They appreciated the decorative colors that matched their houses or garage interior. They liked the way their vehicles looked parked on the floor. They appreciated the overall “neat / clean” look of the garage. They even noticed that they were less likely to fall on the floor due to the increased slip-resistance of the coating.

To avoid the failure factor – the formula is simple – the “Prep Perfect System,” polyurea / polyaspartic, and an experienced applicator.

Here are some of our finished floors – that are guaranteed to work long-term.

Floor Drains and Minnesota Garage Floor Coatings

by Joe Sheehan

October 12, 2010

The History: This home was built in the early 90’s in an upscale development in Woodbury Minnesota. The garage floor was installed with a center floor drain. A handy and useful feature in any garage. Especially in Minnesota, where snow melts from vehicles in the winter.

The Challenge: However, in this case, the drain simply didn’t work. The reason being, the drain was set too high in the floor, which caused a large ponding area around the drain.

To show this, we placed a level between the drain and the surrounding floor. Surprisingly, this challenge is not that uncommon.

The Solution: The “old school” solution is to build up concrete or repair material around the floor drain so that water flows correctly. We’ve seen this attempted numerous times – generally, this solution is short-lived. Often times, the fill will delaminate due to moisture building up around the drain. Add in freeze / thaw cycles and road salts – delamination is inevitable.

Our solution: instead of adding concrete around the drain, we create drain paths. By cutting notches in the cast iron drain bowl, and drainage paths in the surrounding concrete, our solution allows water to easily flow into the drain. Simple. Furthermore, we give our customers a surface that is easily cleanable, and with a soft double headed foam squeegee the customer can move water and debris to the drain in minutes. Leaving the surface bone-dry and ready for use.

To prove that our thought-process and solution worked. We returned days later and flooded the floor with 10 gallons of water and gave our customer a squeegee and asked him politely to clean his floor. And as you can see from the pictures, it worked perfectly. The floor drain that was unusable for the last 15 years now worked as it should.

Concrete Preparation

Installing Garage Floor Coatings with the “Prep Perfect System”

by Joe Sheehan

October 11, 2010

It’s been said: Preparation is 50% of the job. We, at G-F One Coatings, believe when it comes to long lasting Garage Floor Coatings, it’s 100% of the job – so came the phrase, “The Prep Perfect System.” This system was developed by G-F One Coatings and was specifically designed with industry specifications, proven processes, or as we call it – Facts, not opinion. The coating industry has many governing organizations and guidelines for procedures and processes in the preparation of concrete for a coating system. Using all these guidelines and perfecting these procedures, we can install garage floors that are built to last, with guaranteed results.

By the end of 2005, after considerable research and development, we had a long series of processes all based on completeing a coating project in one day. By the end of 2006, the coating technology – fast-cure polyureas – became common in the industry. With the “Prep Perfect System” and this new concrete coating technology, we had completed our two year quest to develop and perfect a one day installation.

The first national publication for polyurea coating, was released in October of 2006. It was written by Joe Nasvik and featured in Concrete Construction Magazine. A quote from the article, “Joe Sheehan, owner of Garage Floors 1, Oakdale, Minnesota, an application contractor, says he’s developed a system for preparing slabs by diamond grinding with a dry vacuum pick-up to achieve an 80 grit profile. “I know that my preparation is good when the primary coat absorbs completely into the surface.”

Concrete Crack Repair, Concrete Preparation

Repairing Concrete Cracks in Minnesota

by Joe Sheehan

October 6, 2010

When it comes to prepping a concrete floor for polyurea/aspartic coatings, properly filling cracks and saw-cuts is critical to the long-term success of the flooring system. Improperly filled cracks, either with poor process or product, is a recipe for failure.

Cracks are challenging for a number of reasons. The first reason, is cracks are vents for moisture release from the slab. They also collect moisture, debris and may expand as concrete freezes and thaws – especially areas, such as Minneapolis, where the seasons change so drastically. All of these factors make concrete crack repair challenging.

So how do you repair concrete cracks?
After extensive testing, of all the existing products and processes, we have found a method with proven, long-term results. It comes down to two things; the process and the product.

The Process
First, all cracks must be jackhammered open (or chased). This opens the crack and creates fresh concrete for guaranteed adhesion with our crack filler. This also removes weak spots or soft spots in the path of the cracks in the concrete. Once the cracks have been opened, they are cleaned and vacuumed out to remove dirt and debris.

The Product
Next, we mix a two part polyurea quick cure crack material. It is then poured / filled into the crack creating a vertical fill. You can see this in top-most picture. We fill the crack so that it is level with top of the concrete floor surface and let it cure.

Once the crack-material is cured, we grind off the excese material and grind the surface so that it is uniform and smooth. It’s now ready for our pure polyurea/aspartic elastomeric coating system.

Case Study: One Rough piece of Spancrete in Minneapolis

by Joe Sheehan

October 6, 2010

Here’s one for the record books.

This case study was designed to show you how we seal and coat a spancrete. Below are some pictures of the job.

History: The home was built in Roseville Minnesota in the late 60’s on a lake. Underneathe the spancrete garage they had built a theater and exercise room. Soon after they had completed the new rooms, the spancrete had begun to leak – causing considerable damage to the new investment.

The leaking had started in the late 80’s. At that time, there were no coating technologies available to correct the problem. The only solution at the time was to caulk shut all the cracks. After that, the coated the floor with a heavy layer of epoxy and glued directly to the epoxy “old-school,” heavy duty linoleum sheets. It lasted 20 years.

Challenges: The first step would be to remove the existing linoleum, epoxy and caulk. After which, the concrete had to be ground smooth. Once the material had been removed and the concrete ground, we then had to identify and repair any existing cracks.

Solution: The solution was to fill all the cracks with a flexible, “membrane-like,” vertical crack filler. Once the cracks had been filled and ground smooth, we had to apply our polyurea/aspartic, elastomeric coating system.

Conclusion: Harsh Minnesota winters and freeze / thaw cycles can wreak havoc on garage floors – including spancrete. Since spancrete tends to flex and move more than conventional garage floor, the choice of the coatings is absolutely critical to it’s longevity. G-F One Coatings has specialized in repairing, waterproofing and coating spancrete garage floor since 2005. See GFOneCoatings.com for more information or call us at 612.919.4414

Installing Concrete Coatings in Cold Weather

by Joe Sheehan

June 19, 2010

Like many Minnesotans, many of the city dwellers have a cabin up north.

Here’s the story: a family had built a log style detached garage near their cabin about 100 miles north of Minneapolis. With Christmas on the way, the family wanted to have their garage coated before the holiday for a holiday gathering. This wouldn’t be a problem for us at G-F One Coatings. Our coatings can be applied anywhere from below freezing and as high as 100 degrees, something many garage floor contractors can’t do with their products.

To start, we ground the surface smooth to remove all the latents in the surface of the concrete garage floor. Once the concrete had been ground, we filled all of the cracks with our “flexible” vertical crack filler. We also repaired all spalling and pop-outs in the surface. Once the crack filler had cured in the repaired areas, we ground it smooth again.

Once the garage floor was completely smooth. We applied our polyurea/aspartic elastomeric coating material. Once the material was down on the floor, we threw in our decorative vinyl composite chip, which is available in a variety of color choices.

Once the base coat was dry, we collected the remaining chip and applied our long-term, ultra-wear resistant pure polyurea top-coat with slip-resistant additive. See G-F One Coatings for more information or call us at 651-748-5999
