1 Spraytek Acrylic FAQ s Question: What is the Concrete Coatings, Inc. SprayTek System? Answer: Concrete Coatings Incorporated Spray Tek Acrylic System is a combination of a modified acrylic resin and specially formulated Portland cements. Colorants are added as needed. We combine the strength of cements with the durability and bonding power of acrylics. A penetrating sealer is applied to provide superb durability, weather and UV resistance and ensure a long product life. Question: How long has this product been in use? Answer: Acrylic resurfacing has been in use since the early 1970 s. Polymer was added in the 1980 s to provide superior bonding properties, and increase strength, durability and longevity. Question: How does this product bond to concrete? Answer: First, the surface is etched with muriatic acid and pressure washed to clean off dirt, remove loose aggregate, and open the concrete pores. Next, a very thin "skim" coat of the acrylic 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 the skim coat is dry. A second coat is applied using a drywall hopper in a random spray pattern, or troweled for multi hued color variations. When this coat is dry, the tape is pulled, revealing the patterns, and two to three coats of solvent based sealer is applied using a roller. This sealer coat penetrates and softens the skim and spray 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.

2 Question: How thick is it applied? Answer: Total thickness is approximately 1/8 3/32". We are more concerned about the acrylic penetrating the concrete than building up the surface. Actually, the thinner it is, the better flexural properties it has, which is very important to allow for expansion and contraction of concrete during freeze/thaw cycles. Skim coats can be applied thicker for holes and spalling (chipping, flaking). Larger and thicker areas are filled or rebuilt using highdensity acrylic mortar called Fast Patch. Question: Will my concrete still heave in the winter? Answer: We cannot eliminate the heaving of concrete. However, after application, the surface will be denser, and much less porous. Large cracks that previously allowed greater amounts of water penetration can be reduced. Consequently, less water is retained and the effects of heaving caused by freeze cycles should be noticeably reduced over a period of time. Question: Is it affected by cold weather? Answer: No. Because it is an acrylic, it remains flexible, yet extremely durable. Freeze/thaw cycles cause concrete to expand and contract. Because the Spray Tek system is essentially part of the concrete surface, it moves with the concrete and not against it, as do other products like tile, slate, pavers, asphalt or concrete patches. Question: How does it stand up against oils, stains, salts and discoloration? Answer: The protective properties of the sealer coat leave a non porous finish. The majority of stains due to oil and grease wash off with mild

3 detergent. Salt, deicers, etc. have no effect on it. 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 maintain its beauty for many years to come. Cleaning can be performed with a mild detergent. Question: Will it wear or chip off? Answer: Concrete Coatings Incorporated Spray Tek Acrylic System should not show any abnormal wear provided the acrylic sealer is replenished as wear occurs. We estimate this to occur no sooner than every two to three years under normal conditions. As long as the sealer is in place, this protective coating should absorb any wear. Any scuff marks, etc. generally disappear with a fresh application of sealer. Question: What are the color choices? Answer: Currently there are 27 standard colors to choose from. Our unique highlighting system provides unlimited color combinations. Custom colors and personalized logos are available at an additional cost. Call for details. Question: How is it maintained properly? Answer: Although the Concrete Coatings Incorporated Spray Tek Acrylic System is extremely durable, it is not indestructible. The rule of thumb is this: if it will scratch, chip or damage concrete, chances are it will damage the

4 Concrete Coatings Incorporated Spray Tek Acrylic System surface also. 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. Question: What about expansion joints? Are they covered up? Answer: Expansion joints and cold 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. Question: What about heaved sunken or severely damaged concrete? Answer: Heaved (raised) concrete, is generally ground down, or the adjacent section is built up using a variety of materials. Severely damaged sections can be torn out and replaced if necessary. This helps to minimize the cost and time of replacing the entire area. Question: Can cracks be repaired? Answer: ABSOLUTELY! All cracks are repaired using high strength epoxies prior to applying the skim coat. New tension control joints are then cut, or existing ones cut deeper, to alleviate the tension and allow for the movement that initially created the crack. (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.)

5 Question: Can it be applied around pools? Answer: MOST DEFINITELY! Concrete Coatings Incorporated Spray Tek Acrylic Systems are the ideal solution for pool and spa areas. They are nonskid, cooler than concrete, and will not stain or be adversely affected by pool chemicals. It also provides a perfect transition from pool to yard, adding 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. Question: How soon can it be used after application? Answer: For normal foot traffic, excluding high heels, cleats, or spikes: 24 hours *; Vehicle traffic: 3 5 days* (* Under normal temperature and weather conditions) Question: What surfaces can it be applied to? Answer: Concrete Coatings Incorporated Spray Tek Acrylic Systems can be applied to any concrete surface, vertical or horizontal.
