2、old concrete that will not chip, fade, crack or peel. Staining solutions contain inorganic salts that when dissolved in water, react with the minerals in concrete to create a beautiful variety of colors.Acid Stains are not paints; they are chemical solutions that react with minerals in concrete. The
3、 chemicals penetrate through concrete pores to form a durable and permanent color. User must understand that this is a chemical process and exercise appropriate safety precautions as described in the Application and Caution sections below.Created to color new and old concrete alike, Triple-S offers
4、a variety of stain colors to choose from. However, because they react with the minerals within concrete, every stained floor will be different. Any concrete surface will contain the proper minerals that are essential to the staining process but every floor will have different concentrations of these
5、 specific minerals. Resultantly, every stained floor will be unique in its appearance. Even certain parts of a particular concrete floor will have a higher concentration of minerals than other parts and therefore, these areas could have brighter and more vibrant coloration. The mottled and varied ap
6、pearance of acid stained floors is common and of the main reasons the process has so much appeal. Acid Stains are very durable and the colors they yield are longer lasting than any concrete coating. Acid Stains penetrate the surface of the concrete and actually react with the top layer, 1/16th to 1/
7、32nd of an inch. They will not chip, fade, peel, scratch or wear off as most paints or acrylic stains will do in time. As a result of this penetrating process, the only way to remove Acid Stain is to grind off the top layer of the concrete. This is a permanent process! Additionally, it should be not
8、ed that Triple-S Acid Stains will not cover blemishes in the concrete. These are not paints and therefore, any blemish in the concrete that was visible prior staining will still be visible afterward. Prior to staining, attempt to repair as best as possible any major blemishes such as holes or crater
9、s.USAGE:Triple-S Acid Stains have been used to decorate outdoor walkways, basements, game rooms, living rooms and bedrooms, kitchen counter-tops, potions, restaurants, retail stores, store fronts, decorative statues and tables, backyards, garages and portions of highway dividers. Uses are limitless.
10、 Triple-S Acid Stains are sold ready to use. However they can be diluted with water if the resulting color is too intense for the purchasers taste. Due to the nature of Acid Stains, too much dilution will neutralize the effects of the acid in the solution and therefore no more than a 20-30% dilution
11、 is recommended. REGARDING OUTDOOR USAGE AND UV LIGHT: Triple-S Offers over 20 colors of Acid Concrete Stains which can be viewed on the color chart. All off our color can be used indoors and outdoors. However, in highly sunlit areas there are five colors that can fade due to Ultra-Violet light: Bur
12、gundy, Brick, Sea Blue, Yellow and Violet. For these colors, the concern is color fading and we recommend using our UV resistant UT-9500 Polyurethane sealer. In our tests, using a UV resistant polyurethane sealer has mineralized the fading of these colors. Nonetheless, we do consider these five colo
13、rs UV unstable and they are recommended for indoor use and/or in low sun-lit, outdoor conditions.COVERAGE:Coverage is dependant on several factors. Generally speaking, Triple-S Acid Stains will yield 200-250 square feet per gallon. However, there are several circumstances that can greatly affect thi
14、s approximation: porosity of the surface, the age of the concrete, the composition of the concrete and the weather at the time of application. The porosity affects the coverage area because a flatter, smoother surface will absorb less stain than a very porous surface; therefore less than a gallon of
15、 stain may be needed to cover a very smooth 200 square foot area. The age of the concrete is important because through normal wear, the surface may not have the necessary minerals needed to react with an acid stain. Normal erosion over time may leave the surface devoid of the necessary minerals. Thi
16、s is even more probable with an outdoor surface that has been exposed to the elements. We recommend to always test a small area of such surface to evaluate the color prior to full use. See Preparation section below. The composition of the concrete is important because as mentioned before, certain co
17、ncrete surfaces may have more or less of the necessary minerals for acid staining. Some concrete slabs simply do not accept acid stain very well. In all cases, we strongly recommend testing a small area prior to full project use! Lastly, the weather can be important because concrete expands with hea
18、t. Therefore, more concrete pores will be exposed on warm days and resultantly more Acid Stain will be absorbed than if applied on a cooler day. On hot days, you can attempt to cool down concrete by wetting it lightly with water and once it dries, apply the stain. If the stain color is too dark, wat
19、er dilution is possible. No more than a 30% dilution is recommended. If one gallon of stain is diluted20% with water, the square footage yielded will also increase by 20%.EQUIPMENT:The most important equipment of all is safety gear. Please wear the appropriate safety gear at times including safety g
20、oggles, rubber gloves, boots and protective clothing. Triple-S Acid stains contain harmful chemicals such as hydrochloric acid and iron chloride. Avoid breathing in their vapor and mist. Avoid contact with skin, eyes and clothing. First Aid: Eyes-Hold lids away from eyes and flush eyes immediately w
21、ith plenty of water and seeks medical attention immediately with plenty of fresh water and seeks medical assistance. Ingestion-drink plenty of water and seek medical attention immediately. Skin-Flush skin with plenty of fresh water and wash with soap. Seek medical attention. SEE CAUTION SECTION BELO
22、W PRIOR TO USE.Cleaning before usage requires the following: a mild detergent, a mop or broom and plenty of fresh water. An acid-resistant wet-vac can facilitate the preparation and clean up process as well. If a wet-vac is not used, please use paper towel, saw dust or old rage to soak up the excess
23、. If the surface has a coating or has been previously stained, a grinding and/or sandblasting machine may be necessary. Application requires paintbrushes, sponges, rollers, lambs wool applicators or a hand pump sprayer, and an acid-resistant plastic bucket. Do not use brushes that have colored brist
24、les as the acid may cause the color to run. We recommend hand pump sprayers that can be bought at hardware store; they are the same sprayers generally used to spray insecticides on plants. They must be completely plastic because the acid solution will corrode metal parts! PREPARATION:This is most im
25、portant step because the end result is very dependent on this process. On the other hand it is a fairly simple process for new and old concrete alike. After a test area has been stained and approved, then staining of the larger area may commence. First the surrounding areas such as walls and shrubbe
26、ry should be partitioned Tape the walls where they meet the ground and it may be necessary to place plastic sheets on the wall as well-this will protect the walls from a spray application. Acid Stains contain chemicals that may cause harm to greenery. Do not allow the solution to come in contact wit
27、h plant life or animals. Partition these areas from outside interference such as pedestrians, cars or animals. Secondly, if the concrete is newly poured, it must cure for 3-4 weeks to properly accept the Trip-S Acid Stain at the desired intensity. It is highly recommended to wait one month for full,
28、 natural curing; no liquid curing materials should be used. Thirdly, both new and old concrete must be thoroughly cleaned prior to staining. They must be cleaned free of oil, sealers, waxes, grease, water repellants, dust, paint, act. Natural debris such as dust and dirt can be removed with warm wat
29、er and mild detergent. A wet-vac may be useful for indoor use; a mop and bucket or a hose and broom may suffice for outdoor cleaning. Make sure the cleaning process is thorough. Results are dependant on the thoroughness of this step. Rinse the area until the run off water is completely clear. There
30、should be nothing on surface prior the staining procedure. Paints and sealers can be removed with a mild, non-acidic paint stripper and a scraper but if the surface is porous, remnants may reside in the pores. Therefore, grinding or sandblasting may be required to remove synthetic substances such as
31、 concrete sealers, paints or oil stains. Grinding and/or sandblasting might also be necessary if a test area is prepared and it becomes clear that the concrete is too weathered to accept the stain. This may happen with outdoor concrete that has been exposed to the elements for a number of years. The
32、 necessary minerals may have been washed away with time and therefore a new layer of concrete should be sought-achieved with grinding, sandblasting or adding a micro topping. Do not acid wash the concrete surface as it will almost certainly kill and remove the necessary reactants in the concrete and
33、 staining may become impossible. Always defer to grinding and/or sandblasting if the surface has a topcoat. Grinding and/or sandblasting will bring a brand new layer of minerals and aggregate to the surface and consequently, better staining. Lastly, once all the proper cleaning procedures have been
34、taken and the surface is believed to be free of any substance, the concrete should absorb water. If water is poured on the surface and the concrete absorbs it and darkens, it is ready to be stained; it is ready to be stained. However, if water beads off in any section of the surface, these areas may
35、 not accept the stain and therefore may not change color. Further cleaning and preparation may be necessary.TESTING:The resulting color of acid stained surfaces will vary from floor to floor depending on the composition, age, texture and temperature of the concrete. As a result, the color may not be
36、 predictable and a test area is highly recommended! Cleaning the test area just as you would the entire to-be-stained area is very important as this can also affect the outcome. The test area should be stained just as the rest of the surface is going to be stained: the same utensils, the same stain
37、solution and the same preparation methods. Once the test has been conducted and the color is acceptable, keep in mild that a sealer will make it a few shades darker. You can seal the test area to see the final outcome, but note that this area will no longer be penetrable by any other solution. Note
38、that is always easier to stain an area darker but it is near impossible to stain an area lighter. Therefore, if you believe the stain will be too dark, make the first test with a diluted solution. If it is too light, then simply use more concentrated stain by repeat application. However, if the area
39、 is too dark from the outset, it will be difficult to cover it with a lighter stain as the darker shade will dominate.Additionally, there are some outdoor floors that will not accept Triple-S Acid Stains. Concrete exposed to hash elements such as rain, water run-off and snow may lack the necessary m
40、inerals for acid staining. Over time exposure to the elements may have washed away the necessary minerals and these floors will not be stainable. In these situations the top layer may have to be grinded off to reveal a new layer of aggregate that will accept the stain, or a micro topping of new conc
41、rete may need to be applied. For floors that do not accept stain very well, a thin layer of concrete, poured on top of the original concrete can be very beneficial. Not only does it cover any all blemishes in the concrete, it also allows you to choose the color of the concrete.White concrete micro-t
42、oppings provide a wonderful surface to stain because of their light color-the colors are usually very vibrant if the micro-topping is lighter than normal cement. Concrete stain generally shows up very well on micro-toppings and if the floor has a lot of blemishes, has a thick topcoat or has been pre
43、viously stained, this is a very good option to consider.APPLICATION:Once the surface has been cleaned thoroughly and all debris has been removed, allow the surface to fully dry. Once dry, the adjoining walls and plants should be taped off so as to prevent contact from potential runoff, spills or ove
44、r spray. Follow SAFETY PRECAUTIONS as described in USAGE AND CAUTION SECTIONS. For a large area, stain solutions are best applied by spraying but application with a paintbrush or roller is suitable as well. Spraying applies the stain more liberally and equally than any other application method (the
45、sprayer MUST be all PLASTIC, the solution will corrode metal parts). If the area is small, then rolling or brushing is suitable. When brushing, use circular motion so as to prevent visible brush marks on the concrete. Avoid splashing, dripping and pudding as these areas will be darker when dry. Also
46、, only use fresh stain on new surface areas. Do not spread reactive residue from an already stained area to a new area. Always use fresh stain. When Triple-S Acid Stain is applied, it will “fizz” and a reactive odor and gas may arise. Some colors will fizz more than others and this can be for any nu
47、mber of reasons. Some concrete may be too weathered and devoid of the necessary minerals to react with the stain. This may also depend on which particular Triple-S Acid Stain is being used. Five of Triple-Ss Acid Stains contain coloring agents dyes along with acid and other inorganic minerals. These
48、 colors are Burgundy, Brick, Violet, Yellow and Sea-Blue and these stains may not fizz as mush as other Triple-S Acid Stain. When applying Triple-S Acid Stains to a larger area, spraying is the recommended method. The walls should be taped off and the floor, approximately six inches from the wall, s
49、hould be stained using a brush or roller. If this is done, there is less risk of residual spray affecting the walls. Then, with a plastic hand pump sprayer, spray the remaining sections of the floor. Apply enough stain to fully saturate the surface of the floor but avoid pudding. Also, keep the spray tip at least 12 inches way from the surface of the concrete in order to apply the stain liberally. Most of the time, if a second color is applied; we recommend not washing off th
