Garage Epoxy Flooring Concrete Repair

Epoxy floors aren’t only elegant but also durable. For this, epoxy flooring is widely used for basement and garage flooring. However, the exposure to constant pressure every time you park your vehicle weakens the concrete over time. The floor doesn’t only lose its attractive polished sparkle but the shrinkage cracks pose a danger to garage users and your vehicle’s tires.

In this simple yet practical guide, we lay down common garage epoxy flooring problems. We also highlight the steps that you need to follow to restore the floor’s sparkle.

Signs that Garage Epoxy Flooring Concrete Needs Repair

Floor coating peeling

This often happens if the epoxy garage floors coating didn’t bond with the concrete slab. The problem is especially amplified if your contractor made the concrete too smooth making it hard for the resin to stick on the concrete.

The peeling can also be caused by soaked-in grease and oils, high humidity, and exposure to extreme temperature levels.

Air bubbles

If an epoxy coat is mixed too fast or applied on a non-porous concrete slab, air bubbles often form underneath the surface. This creates an uneven surface with the sunken points likely to crack under pressure.

Moisture buildup and clogging

When laying the garage surface, the surface must be completely dry before you apply an epoxy coat. If the coat is laid on a wet slab, moisture is trapped underneath the epoxy coating. This moisture doesn’t only force open the epoxy coat but it can also split the yet to dry concrete creating cracks on the newly completed surface.

Improper drainage

An ineffective drainage system can lead to structural damages that may render your garage unusable.

A tell-tale sign of poor drainage or blocked eaves troughs is the formation of water pools on your garage surface. With time, the floor starts to chip or crumble and also loses the surface shine.

How to Repair Garage Epoxy Flooring Concrete

Cracks

For small cracks, fill in the affected areas with a concrete mix then spread and smooth it out. Once dry, clean the surface and apply an epoxy coat. You can also use a filler to mask the cracks out of view for a short period.

If the cracks are widespread on the surface, it’s paramount to call in a professional to assess the cause and extent of the damage. This can save you unnecessary costs such as constant refilling when you need to replace the whole floor surface.

Crazing

Crazing occurs when several small cracks get interconnected to form a huge crack. Crazes often have a hexagonal shape. To prevent crazing, spray a monomolecular curing compound on the concrete slab during the laying stage. Always let all bleed water to escape on your wet concrete slabs to make them strong before applying the epoxy.

If the crazing occurs when the garage is already in use, call in a contractor to do the repairs or replace the floor in its entirety.

Epoxy Floor Blistering

Cratering and pinholes occur when the concrete is exposed to direct sunlight during the curing process making it dry too fast. When an epoxy coat is applied, the floor surface develops a blistered appearance.

To fix blistering on epoxy floors, buff the surface to even it out and then apply a new coat of epoxy. Sanding the affected areas ensures that the concrete slab is porous making it easy for the epoxy to stick. If you haven’t worked with resin in the past, call in an expert to ensure you get a long lasting surface.

Final Word

A tattered epoxy floor makes your garage appear run down and potentially harmful to users. By leverage on the tips above, you can carry out a DIY repair project and restore the surface. If the issue is beyond your skill level, it’d help to call in a professional flooring contractor to complete the project to your satisfaction.
