Outline (Read all instructions before starting):

Clean and prepare the concrete

• Mask off area
• Dilute stain with water 1:1
• Spray on first coat and brush in
• Let first coat dry and then wait an additional hour
• Rinse with clean water, scrub to remove residue and rinse again until rinse water runs clear
• Apply second coat to ensure complete coverage in lighter areas
• Wait 2-4 hours
• Clean and neutralize concrete
• Allow to dry overnight or longer until completely dry
• Apply 2 coats of SRI Clear Acrylic Sealer letting dry about 12 hours in between coats
• Use a mop on floor wax a few times per year (depending on traffic) to preserve the sealer finish

RENAISSANCE™ Concrete Chemical Stain penetrates concrete in varying degrees of intensity depending on the composition of the concrete resulting in mottled shading of colors. While these are the very characteristics that render a natural appearance, a test section should be produced for approval prior to the general application of the chemical stain. Whenever possible, this test should be applied on the actual concrete slab to be stained. An adequate size sample should be produced so a good judgment of the final appearance can be made. It is important that the same worker, equipment, and techniques that produced the sample be used for the finished project. Due to differences in cement, aggregate, admixtures, and finishing techniques used when placing concrete, chemical stain may produce results that are completely unexpected. Owners should be made aware of this potential issue and should understand that there are no guarantees with coloration, unusual fading, or even darkening over time.

COVERAGE RATE

• One gallon(diluted or full strength) covers 200-250 square feet
• Recommended dilution is 1:1 with water, therefore if you buy one gallon, after dilution you will have 2 gallons.
• Two applications are recommended for most jobs

SURFACE PREPARATION

New concrete should be allowed a minimum of fourteen (14) days to cure. Cooler climates, (highs not reaching 50 F) require curing times of twenty-one (21) to twenty-eight (28) days. Liquid curing agents should not be used. Concrete must be thoroughly cleaned and rinsed before chemically staining. Water must easily penetrate the surface. Spotting the surface with water can check this. The water should darken the surface and be readily absorbed into the concrete. If water “beads” and does not penetrate, additional curing and/or surface preparation must be done.

NOTE: If adequate curing time has elapsed and water still does not penetrate, then a curing compound may be present and must be stripped. If this occurs, testing or other investigation may be required to determine what type of stripper to use.

The concrete surface should be pressure washed with a fan tip or cleaned with a rotary machine and swept. Clean all dirt and loose debris from surface using detergent(such as TSP: TriSodium Phosphate) when necessary. A commercial degreaser works well in removing some mild oil and grease stains. Oil, grease, and other petroleum stains that are permanent will not accept chemical stain. Chemical stain should not be used over petroleum stains.

NOTE: Since RENAISSANCE™ Concrete Chemical Stain reacts with cement paste, aged or broom-finished concrete may not produce the variegated appearance that new troweled concrete produces.

PROTECTION

Surrounding areas and foliage should be protected prior to staining. The work area should be roped off. All adjacent vehicles should be removed and the roped areas closed to foot or vehicular traffic. Any adjoining walls should be masked. Wear approved acid vapor respirator NIOSH/MSHAA TC 23C. Provide adequate ventilation and sufficient local exhaust as needed to maintain exposure below TWA and TLV limits. Wear chemical-resistant gloves and chemical splash goggles. Wear suitable protective clothing, chemical resistant apron and boots to avoid skin contact.

APPLICATION

RENAISSANCE™ Concrete Chemical Stain should be applied by using a pump-up sprayer with all plastic components. RENAISSANCE™ Concrete Chemical Stain contains hydrochloric acid and will corrode metal components. Liberally apply one coat of chemical stain while agitating surface with an acid-resistant brush. For best results, maintain a wet edge. Brushes should be uncolored, acid-resistant nylon bristles with a medium stiffness and able to hold liquids. Airless sprayers are not recommended. Do not splash, drip or allow the chemical stain to puddle in joint areas or other depressions unless a changed color affect is desired in those areas. Do not walk on the wet surface. Footprints will appear darker than the adjacent areas. If stepped on by accident, the footprints should be brushed out immediately.

The liquid chemical stain color will not resemble the final color produced on concrete surface. The color changes as the chemical reactions take place. RENAISSANCE™ Concrete Chemical Stain has a slight bubbling or fizzing action when applied. Use a circular motion and keep the brush in constant contact with the surface in a continuous motion. To avoid lap marks, previously reacted chemical stain should not be spread to the new work areas. It should be brushed back over the section just treated.

RENAISSANCE™ Concrete Chemical Stain should be diluted for use. Dilute one(1) part stain to one(1) part water for normal usage. Color as well as shading may change depending on dilution. Other dilutions may be used, but dilution should be no more than one (1) part chemical stain to four (4) parts water. Test samples should always be produced to inspect results of diluted solution.

When applying chemical stain to vertical surfaces, application should start at the bottom and work upward. Excessive run down should be avoided.

Two applications are normally required on concrete. However, color is related to number coats as well as time before rinsing. Premature rinsing will generally lighten the color but may cause undesired, dramatic shading. Final coat of chemical Stain should be allowed to dry before rinsing unless different effects are desired. When multiple colors of chemical stain are to be layered, the first color residue should be cleaned off before the application of the second color and/or the third color, etc. This allows the color effect to the last color applied to be evaluated before another color is applied.

One coat usually produces the desired results when staining polymer cement. Polymer cement accepts chemical stain more readily than concrete. RENAISSANCE™ Concrete Chemical Stain may completely change the color of the polymer cement.

CLEAN-UP & NEUTRALIZING

After staining, rinse until the rinse water is completely clean. A solution of 5-10% sodium bicarbonate(baking soda) and water should be applied to the surface to neutralize it. Use an acid resistant nylon bristled brush to scrub the surface and to remove all residue. If available, a rotary floor scrubber or buffer should be used to clean the surface. Rinse the surface again to remove all residue and neutralizing solution. An all plastic, acid resistant shop-wetvac can be used to collect all wash water. All residue, run off, cleaning water, and absorbent materials must be discarded and disposed of in accordance with all local, state, and federal regulations.

SEALER

Two coats of SRI Clear Acrylic Sealer are required to complete the project. The surface must be clean, completely dry and at least 45° F during the sealer application. Open the pail of sealer and mix thoroughly with drill. To apply with roller, use a solvent resistant, 1/4″ nap. Apply one thin coat forcing the sealer into the low areas of the texture. Allow sealer to dry (this could take up to 12 hours) then repeat the process(for second coat use non-skid modified sealer if desired). To apply with an airless sprayer, use a size 8/13 reversible tip and spray evenly onto the concrete surface.

CURE TIME: Allow twenty-four (24) hours before permitting foot traffic on sealed area. Allow seventy-two (72) hours before permitting vehicle traffic on sealed area.

SRI 25% Clear Sealer

Acrylic Concrete Sealer

DESCRIPTION

SRI 25% Clear Sealer is a tough, high solids (25%), pure acrylic concrete sealer in a solvent base. It is designed to protect and beautify all types of concrete with a high gloss durable clear coating. SRI 25% Clear Sealer is non-yellowing to preserve the appearance of all types of decorative concrete.

USES

SRI 25% Clear Sealer protects and beautifies all types of concrete such as colored, stamped, and exposed aggregate. It also protects pavers, terrazzo, stones, and stained concrete. SRI 25% Clear Sealer can also protect and add gloss to Chattahoochee stone. Paver joints will be stabilized and pavers will be sealed.

TOOLS REQUIRED

Use brush for cutting in tight spots. Use short nap roller for smooth concrete and longer nap roller for rough concrete. If using tray, do not use thin plastic. Use metal or heavy duty plastic container. Alternately an airless sprayer can be used.

COVERAGE

• Two coats are recommended. One coat application is possible if applied at proper rate and cross-rolled.
• Exposed Aggregate concrete-Apply at rate of 100 square feet per gallon
• Textured and stamped concrete-200 square feet per gallon
• Broomed concrete-NOT recommended due to highlighting of imperfections in concrete and darkening of concrete.
• Trowel finish, tile, terrazzo and other slick surfaces-Apply at rate of 300 square feet per gallon.
• Pavers- 100 square feet per gallon. Use metal sprayer.

PREPARATION

Clean dirt, wax, grease, oil and other contaminants from the surface. Be sure to remove any foreign coating unless previous coating is same or similar oil based sealer or stain. Make sure the surface is clean, dry and sound. Clean oily concrete with SRI CONCRETE CLEANER DEGREASER or other degreasing soap. Use a bristle brush for heavily oiled spots. If surface is slick, etch with SRI ETCH & CLEAN. Rinse well with a pressure washer. Allow 24 hours to dry. Apply only when surface and air temperatures are above 50° F and below 90° F. Do not apply to excessively hot surfaces as rapid drying may cause bubbles to form. For pavers, sweep away any loose sand.

PROTECTION

Wear Safety glasses and gloves.

APPLICATION

Brush may be used where roller won’t reach. Do not pour directly from can to concrete. Apply evenly from can or other metal container with appropriate roller. Use a long nap roller for exposed aggregate, a medium nap roller for textured surfaces and a short nap roller for smooth surfaces. Keep roller soaked by dipping on every stroke. Every few feet turn perpendicular to the first coat, and cross roll without re-dipping. Wait until the surface is tack-free before applying a second coat. The continual dipping with the first coat gives a heavy application and the cross-rolling allows for an even application. If spraying, use a metal container and clean up immediately with aromatic solvent such as A-100, Xylene, toluene, or lacquer thinner containing the previously mentioned solvents. Do not thin product.

DRY TIME

Dries to walk on in 4 hours to a glossy shine. May be driven on in approximately 72 hours. Cooler temperatures will increase drying time significantly.

FINISH

SRI SUPER SEALER WAX is recommended for slick troweled interior or covered concrete, such as garage floors. SRI SUPER SEALER WAX will add a deep gloss finish. It is a sacrificial coating that adds scuff and skid resistance. SRI SUPER SEALER WAX protects the SRI 25% Clear Sealer, and will add to the life of the coating and should be re-applied as necessary as a part of your routine maintenance.

SLIP RESISTANCE

On slick concrete floors, you may add SRI SUPER GRIP as a non-skid paint additive to the second coat of SRI 25% Clear Sealer.

CLEAN UP

Clean application tools and equipment with Aromatic Solvent such as A-100, Toluene, Xylene, or Lacquer Thinner containing one or more of the previously listed ingredients. These solvents are flammable, and proper caution should be exercised.

STORAGE

Product will not freeze. Re-seal unused product completely and store in ventilated area away from open flames. One gallon can will close by hammering lid on can. Five gallon pail cannot be adequately re-sealed. If you smell solvent after closing lid, finish using product or discard.

MAINTENANCE

Clean floor with water. Do not use ammonia based cleaners. For interior floors SRI SUPER SEALER WAX is recommended as sacrificial coating to protect the hard sealer film from scratching.

LIMITATIONS

Not recommended for brick due to bricks tendency to absorb moisture from under seal. Sealer will melt plastic, asphalt, or any petroleum-based product. Any surfaces not mentioned should be tested in small areas before applying sealer. NOTE: Gasoline and other Auto parts cleaners containing hot solvents will melt stain. Wiping will smear stain. Allow to dry. Either leave be for protection or re-coat with stain for best appearance. If floor will be regularly exposed to chemicals, it is highly recommended that you test a spot before proceeding with whole floor.

TROUBLESHOOTING

If discoloration, streaking, splotching, and/or cracking occurs, it is usually due to insufficient coating (see Application rates). A second coat is recommended. If fogginess occurs due to insufficient drying of concrete beforehand, apply an aromatic solvent such as A-100, Xylene, toluene, or lacquer thinner containing the aforementioned solvents to melt sealer and release moisture. If buildup occurs due to years of repeated application, application of aromatic solvent such as A-100, Xylene, toluene, or lacquer thinner is recommended to restore shine. Protective coating
should last 2-4 years. However, the gloss will fade sooner if exposed to the sun. Bubbles may sometimes occur, but will dissipate and not affect the seal. SRI 25% Clear Sealer may be used on fresh concrete to cure and seal and on old concrete to protect and beautify.
