Frequently Asked Questions
A concrete overlay is a process used to resurface an existing slab of concrete with a decorative element or is used as part of a restoration project. Our overlays are a polymer modified cement product. Features of our concrete overlays include:
- Freeze-thaw resistance
- Salt and alkali resistance
- Stain resistance
- Outstanding flexural properties (allows for concrete thermal expansion)
- Cured product is non-flammable
- Can be applied from feather edge to 2-plus inches thick
- Provides excellent weathering capabilities for application to exteriors and garages
- Provides a permanent seal against water and moisture contamination and erosion
First the surface is grinded and pressure washed to clean off dirt, remove loose aggregate, paint and open the concrete pores. Next a bonding agent is used for adhesion. Then, a coat of the modified cement mix is applied by trowel. This is to provide maximum absorption into the pores of the concrete. Patterns are laid out using reinforced tape. When this coat is dry, the tape is pulled, revealing the patterns, and 2-3 coats of solvent based cure and seal is applied using a roller. This cure and seal coat penetrates all coats and bonds all layers to the concrete. When dry, these two layers become a permanent part of the existing concrete, providing outstanding weather and stain resistant properties.
The protective properties of the cure and seal coat leave a non-porous finish. The majority of stains due to oil and grease wash off with mild detergent. In addition, because of its unique UV (ultraviolet) additive, it will not discolor due to exposure to sunlight, even in the harshest of conditions. It should be noted however, that periodic cleaning will help to maintain its beauty for many years to come.
The systems should not show any abnormal wear provided the seal is replenished as wear occurs. We estimate this to occur no sooner than every 3-4 years under normal conditions. As long as the cure and seal is in place, this protective coating should absorb any wear. Any scuff marks, etc. generally disappear with a fresh application of cure and seal.
Currently there are many standard colors to choose from. Our unique highlighting system provides unlimited color combinations. Custom colors are available.
All products carry a 5-year manufacturer’s limited warranty against excessive fading, delamination and product failure. In addition, we provide a 1-year workmanship warranty on all of our work. It is strongly recommended that seal be reapplied at least every 3-4 years to provide a long product life and protect the various stains
Although the systems are extremely durable, they are not indestructible. The rule of thumb is this; if it will scratch, chip or damage concrete, chances are it will also damage the decorated surface. Exercise caution when setting heavy things on it. Take care not to drag heavy items that could scratch it. Periodic washing is all you should have to do to maintain the surface. Clean oil spills and the like as quickly as possible to keep it looking new.
Expansion joints or control joints are necessary to prevent cracking of the concrete. Concrete must be allowed to expand and contract with temperature changes. These joints provide a ‘controlled crack’ for this movement. All expansion joints are left in place, we cannot cover them up. We also re-cut all existing joints a little deeper to ensure that when it does move, it moves where we want it to and not at some undisclosed weak spot.
All cracks are repaired using high strength epoxies prior to applying the skim coat. New tension control joints are then placed, or existing ones cut deeper to alleviate the tension and allow for the movement that created the crack initially. Note: Due to the multitude of parameters that can cause cracks, cracks cannot be guaranteed against re-cracking; however, cracks that return are often barely noticeable, and if necessary repairs are virtually undetectable.
Most definitely. The modified cement products are the ideal solution for pool and spa areas. They are non-skid, cooler than concrete, and will not stain or be adversely affected by pool chemicals. They also provide a perfect transition from pool to yard and add that finishing touch like no other product can. Because of its versatility, a stencil can be used to indicate depth markings or areas of safety concern.
