The garage is the busiest and the neglected place in the house. It is directly exposed to the harsh working conditions.

The garage floor is used for storing redundant materials and for parking vehicles. It has to carry all the weight of parked vehicles and stored items.

Oil and chemicals can leak most frequently from the vehicles during the parking and servicing. The oil can penetrate through the concrete and stain the surface.

The oil stains reduce the life of the concrete if it is not removed. The floor surface can also get damaged from the falling objects and tools.

This can impose permanent holes, cracks or dent on the floor surface. These stains and cracks can make the surface ugly and bad looking.

It is therefore imperative to seal the garage floor to protect the concrete surface from all the above mentioned ills. Multiple types of sealing elements are available in the market. In this article we will highlight the common pros and cons of sealing the garage floor.

At the end we will also shed light on the popular type of sealers.

Pros of Sealing Garage Floor

The sealing of the garage floor has a number of benefits. The most notable pros are listed below.

Covers cracks & holes

The concrete surface of the garage floor is directly exposed to wear & tear. It can get cracks, holes or dents from falling objects.

The concrete surface can also depress under the load of heavier vehicles. Applying a suitable seal on the surface conveniently hides all the visible cracks, holes and dents imposed on the concrete layer.

The coating not only covers the existing cracks, it also excellently restricts the new potential holes or dents.

Thus a sealer layer helps to protect the concrete surface and enhances the life of the concrete. A concrete layer without a suitable sealer can get damaged quickly.

Impact Resistant

The garage floor surface has to bear heavier loads of vehicles and power tools. Tools can also fall from the hands of the technicians during the repair and maintenance activities.

The falling objects and tools can incur a dent and damage the concrete surface. The sealers are designed to withstand heavy loads and resist impact as well.

By resisting the impact the seal coating also increases the life of the concrete surface. This is also a great feature of the sealers to protect the garage floor surface.

Avoids Chemical Stains

Chemical solvent spills commonly from the vehicle during the repair and maintenance activities. It causes stains on the floor surface which are difficult to remove if not cleaned.

The concrete surface can easily absorb the chemical spillage and make the surface ugly and unpleasant. The sealers coating makes the surface glossy.

It effectively resists the chemical penetration into the concrete surface and makes the surface clean. A suitable sealer layer is really useful to protect the concrete surface against the effects of the chemical spillage.

Prevents Oil Stains

Oil stain is the major cause of black spots on the garage floor surface. Oil leaks frequently from the vehicles during the oil change.

The oil can quickly penetrate through the concrete surface and make it black. The oil penetration stains are difficult to remove from the floor surface.

A sealer surface efficiently resists oil staining and also enhances the life of the concrete surface. A good quality sealer not only resists staining it also increases the life and reliability of the concrete layer.

High Sheen Finish

A naked concrete surface gives a rough and dirty look. It also leaves a lot of dust and dirt and makes the floor dirty and ugly.

A suitable sealer coating imparts high sheen finish to the floor surface. The sealers are added with different additives which make the surface glossy.

The vehicles reflect beautifully on this glossy surface and give a nice look to the users. The glossy layer is also easier to clean and maintain. This surface can be easily cleaned with a wet cloth or mop.

Repels Moisture

The garage floor surface is also exposed to the elements and rain water can enter the floor most often. The moisture can cause rusting and corrosion to the parked vehicles.

It can also destroy the tools and spares stored in the garage. A sealer coating creates a barrier between the concrete slab and moisture. The moisture cannot seep to the concrete surface and thus prevents rusting effects.

A good quality sealer layer repels moisture effectively and protects the floor surface against the side effects of the moisture.

The moisture is the most dangerous element that not only rusts the vehicles it also makes the surface slippery. The slippery surface causes slipping and falling accidents. So the sealer layer is helpful to avoid falling accidents in the garage.

Protects Against Frost

Frosting is also similar to the moisture. The only difference is it is caused in seasonally low temperature regions. The floor surface can get wet after absorbing water in the winter season.

The frosting also makes the work difficult. A sealer coating efficiently prevents frosting in the garage floor. It prevents water seepage to the concrete surface and protects it against the harmful effects of the frosting as well.

Every kind of sealer is not useful for the low climate area. It is therefore imperative to choose a right sealer according to the climate conditions to make the surface resistant against frosting and low temperature.

Frosting can remove the surface coating of low quality. A high quality sealer which is compatible with the climate conditions must be used for these regions.

Increase Durability

The concrete floor can be damaged due to impact of falling objects and load of heavy vehicles. A sealed surface effectively resists staining, impact and moisture.

By applying a good quality sealer a barrier layer is created between the concrete slab and top layer of floor surface. The concrete slab is therefore protected against all the side effects of the garage.

A sealer layer helps to increase the durability of the floor surface. It is therefore necessary to apply a suitable sealer layer on the garage floor surface to protect the concrete and enhance the durability of the floor surface.

Dust Proofing

Simple concrete gets a lot of dust and makes the floor dirty and untidy. The cleaning of concrete surface is tough in comparison to the high finish sealer layer.

The sealer layer restricts the dust accumulation on the floor surface and makes it tidy and clean. A high quality sealer layer must be applied to make the floor surface dust proof.

Cons of Sealing Garage Floor

The sealing of the garage floor also has some disadvantages which must be taken care of.

A bit Expensive

Several type sealers are available in the market. Epoxy is the most widely used sealer for the garage floor. Good quality epoxy sealers are very expensive and you have to spend a lot of money to cover the entire length of the garage floor.

The high sheen gloss finish comes with a hefty price. Low price sealers are available in the market. But the problem is the service life of these sealers is not very high.

Layers of low quality sealers start chipping away after some time. Low quality sealers are required to be recoated after some time, so it also increases the price of coating.

Requires Maintenance

The sealer coating is not the final step to make the floor surface resistant against staining and cracking. It needs regular maintenance to keep it in good shape.

The floor surface has to be coated again to maintain its look and quality. This again requires some money to keep it maintained.

Becomes Slippery When Wet

A Sealer coating provides a high sheen finish to the garage floor surface. This glossy surface becomes slippery when it gets wet.

The slippery surface can cause slipping and falling accidents. It is therefore necessary to clean and dry the floor surface on a daily basis to avoid slipping and falling incidents.

Some sealers are reinforced with the anti-slip additives which give the surface stone finish. This stone and rough surface conveniently resists the slipping.

Again the problem is money, this type of sealer is more expensive than the common sealers.

Take Time for Sealing

A sealer coating does not quickly seal the surface. It may take a few days to completely settle. Sealer may take 5-10 days to dry and seal the surface thoroughly.

During this time the garage floor surface cannot be used for parking and maintenance activities. For commercial garages this results in a downtime.

Shifting of Store Material

The items stored in the garage have to be removed to apply the sealer coating. For sealing the concrete is prepared and then the first and finish coat are applied to make the sealer surface hard and tough. Shifting material also takes some and labor cost.

Types of Sealers

The most common type of the sealers is listed here under:

Epoxy

Epoxy coating is the most commonly used sealer for the garage floors. The epoxy coating is a bit expensive but it is the most durable and reliable sealer for coating the garage floor surface.

It can be easily applied on the floor surface. The epoxy coating excellently protects the concrete surface and enhances the life span of the concrete.

The epoxy coating is not a permanent solution for sealing the floor surface. It required regular and proper maintenance to maintain the surface in a good shape.

Polyurethane & Poly aspartic Coating

The polyurethane sealers are provided with the additives that make the surface rough and hard. This type of coating layer is scratch and slip resistant.

It also restricts the staining of the floor surface. It is best suited for the high traffic garage. The setting time of this type sealer is also comparatively lower than the epoxy coating surface.

The only problem is that it is more expensive than the other sealers.

Stained Concrete

The stained concrete sealer is another viable sealer for the garage floor. It provides a marble like finish to the floor surface. The application of this sealer is also easier and efficient.

The durability of this type sealer is very high. It also enhances the beauty and aesthetics of the floor. The problem is these are prone to scratches.

It can get quickly damaged due to rain and moisture. The yearly maintenance is also required for maintaining the floor surface.

Paint Concrete

The painting is one of the easiest and quick fixes to the floor surface. It can be applied easily over the entire length of the garage floor.

The cost and maintenance of the painting is also very low. The shape of the painted floor surface becomes dull after a short period of time. The chipping of the painted floor surface starts quickly and it lasts for less time than the epoxy coating.

It is not very good resistant to the staining and rain water. It is therefore recommended to touch up the surface twice in a year to make it durable and effective.

The Final Word

The naked concrete surface of the garage floor is exposed to the water, moisture, staining and load. The surface can quickly get damaged if it is not protected against all these elements. A sealer coating is the best and viable solution to keep the floor surface safe and secure. Sealing the floor surface has some pros and cons which have been highlighted above.

A high quality sealer not only protects the concrete surface, it also imparts a beautiful high gloss finish to the surface which changes the overall look of the garage floor. The existing cracks and holes are also covered conveniently. Oil and chemical stains can also be prevented by applying a suitable sealer coating. It makes the cleaning maintenance of the floor surface easier and efficient.

A Sealer coating is a bit expensive and requires some money for coating and maintenance. It also takes a while to completely settle down and seal the surface.
