PreStain Color
- What it is: A water-based, penetrating color stain for concrete, masonry, wood, brick, and composite surfaces - not a topical paint, so it won’t peel or flake.
- Best for: Homeowners and contractors who want a natural, translucent stone-like color on patios, driveways, walkways, interior floors, countertops, and decorative walls, indoors or out.
- Stands out because: Low-VOC and odorless enough for occupied interior spaces, available in 15 designer colors, and dries in 12–24 hours so you can move to sealing the same day or next.
- Keep in mind: PreStain alone only holds up to light foot traffic - for driveways, garages, or vehicle traffic, plan on topping it with a SEMCO sealer like Titan Shield Gloss or Natural Shield

Reduces Freeze Thaw Damage
Penetrating Color Stain
Low Odor & Low VOC
Made in USA- Color & Finish - Translucent, natural stone-like finish that lets the substrate’s texture and movement show through, so every surface has a one-of-a-kind look. - 15 designer colors spanning warm earth tones, cool grays, charcoals, and deep browns. - Unique catalytic reaction with concrete produces natural color variation rather than a flat, uniform paint look.
- Durability & Performance - Solidifies crumbling or spalling surfaces as it penetrates and bonds. - UV resistant - won’t fade under direct outdoor sun exposure. - Freeze-thaw resistant for climates with cold winters. - Passed EN 13144 and ISO 4624 (pull-off) adhesion testing.
- Health & Environmental - Low VOC (independently noted at roughly 6.4 g/L, well under standard limits) and meets indoor air quality standards. - Odorless and non-toxic — safe for occupied interior spaces with minimal ventilation.
- Application & Cleanup - Applies with sponge, brush, foam roller, or airless/fine pump sprayer (tip size 17). Dries in 12–24 hours before sealing, depending on temperature. Easy cleanup with soap and water, no solvents required.
- Penetrating color, not surface paint. PreStain reacts with and soaks into the substrate rather than forming a film on top, so the color won’t peel, chip, or flake the way a topical paint can over time.
- Truly multi-surface. Unlike most stains that are limited to one material, PreStain is formulated to work across concrete, wood, brick, masonry, stucco, and composite materials — one product for patios, decks, walls, and countertops alike.
- Safe for occupied indoor spaces. Its low-VOC, odorless, non-toxic formula means it can be applied in homes, restaurants, retail spaces, schools, or hospitals without heavy ventilation or fumes.
- Fast turnaround. With a 12–24 hour dry time before sealing (temperature
dependent), a project can go from bare substrate to stained and ready-to-seal in about a day. - Built to handle the outdoors. UV-resistant and freeze-thaw resistant, so exterior color stays vibrant through sun exposure and winter cycles without fading or cracking.
- Designed to pair with a sealer. PreStain is engineered as the color layer in a system - apply it first, then protect it with a compatible SEMCO sealer for the traffic level and finish (gloss or matte) the project needs.
- Concrete patios, walkways, and driveways — refresh dull or aging concrete with rich, lasting color instead of replacing it.
- Interior concrete floors — a low-VOC, odorless stain that’s safe to apply in occupied living spaces.
- Garage floors — as a color layer under a traffic-rated sealer like Titan Shield Gloss.
- Concrete countertops and decorative accents — a controllable, brushable/sprayable finish fornsmaller detailed surfaces.
- Brick, masonry, and stucco walls - adds color to aging exteriors without sealing off the substrate’s ability to breathe.
- Wood decks, fences, and outdoor furniture — enhances natural grain while adding protective, fade resistant color.
- Below-grade concrete — freeze-thaw and moisture-tolerant formulation suited to basements and other below-grade surfaces (substrate must still be within the
product’s moisture limits — see Technical Specs).
Note : PreStain Color can only be applied to unpainted and porous surfaces.
- Prep the surface. Clean and dry the substrate fully. For concrete/masonry, use NuLift Cleaner and Stone Soap to remove mineral deposits or efflorescence; use Power Cleaner plus Nu-Lift Cleaner if there’s oil or grease. For wood, sand with 60-grit sandpaper and remove loose coating/debris — avoid pressure washing wood beforehand. Confirm substrate moisture is at or below 3%.
- Mask off any areas not receiving stain. Remove tape before the material fully cures.
- Apply PreStain with a sponge, brush, foam roller, or airless sprayer (tip size 17). Work in small sections, lightly saturating the surface and immediately back-brushing or using a pad applicator to eliminate puddling and evenly distribute color. Apply thin, even coats — don’t overload the tool or let product pool on the surface.
- Build color as needed. Repeat application for more color saturation, letting each pass dry before the next.
- Let it dry 12–24 hours depending on temperature before applying a sealer.
- Seal for protection. For light foot traffic, PreStain can be left unsealed; for furniture, foot traffic, driveways, or vehicle traffic, apply a SEMCO sealer (Titan Shield Gloss for maximum durability and traffic resistance) over the fully dried stain.
Application conditions: Apply between roughly 40–90°F; avoid application if rain is expected within 24 hours, and avoid direct afternoon sun or temperatures above 85°F, which can cause the product to dry too fast to properly bond. Stir well before use to keep color pigments mixed. Over-application can lead to peeling or cracking, so thin, even coats are essential.
PRODUCT INFO
Engineered for professionals. Easy enough to apply yourself.
SEMCO PreStain Color is a water-based, reactive/penetrating color system that delivers rich, lasting color to concrete, masonry, wood, brick, stucco, and composite surfaces - indoors, outdoors, and even below grade. Instead of sitting on top like a paint or topical coating, PreStain penetrates into the pores of the substrate and reacts with it, so the color becomes part of the surface rather than a film that can peel or wear off. The result is a translucent, natural-looking finish that still lets the trowel marks, texture, and organic variation of the concrete show through — no two applications look exactly alike.
PreStain is low-VOC, odorless, and non-toxic, so it can be used safely in occupied interior spaces with minimal ventilation. It’s also fade-resistant and freeze-thaw resistant, making it equally suited to a sun-exposed exterior patio or a below-grade basement floor. Because it’s a stain and not a wearable topcoat, PreStain is typically finished with a SEMCO sealer (Titan Shield Gloss, Natural Shield, or Sealer Matte) for added protection and traffic resistance.

FOR STEP-BY-STEP GUIDES SPECIFIC TO YOUR PROJECT
Prepare your surface and Gather your materials
• For concrete or brick surfaces we recommend our Preparation D in order to remove any mineral deposits or efflorescence from the surface. For this you will need the following cleaners : Nu-Lift Cleaner and Stone Soap • If there is constant dampness in the substrate, use Natural Shield first to mitigate the moisture. Let it fully cure first prior to applying SEMCO Liquid Membrane™ . Ensure your surfaces are fully cleaned and dried. Gather all the products and tools needed for your project.
Fabric Reinforcement
If you have any cracks wider than 1/4", a Fabric Reinforcement is needed to bridge the crack. Any cracks smaller than 1/4" width, SEMCO Liquid Membrane™ can be applied over it. To apply the Fabric Reinforcement, apply a generous coat of SEMCO Liquid Membrane™ over the crack. Put the Fabric Reinforcement on a press it flat, after 10-15 min apply another coat of SEMCO Liquid Membrane™ over the Fabric Reinforcement to encapsulate it. Let it dry to the touch before applying SEMCO Liquid Membrane™ over the entire surface.
Masking
Mask off areas that are not receiving any coating. Remove masking tape before material has fully cured.
APPLYING COAT
Use a 1/2" nap roller. Allow any pre-treated areas to fully dry. Apply a thin coat (0.015 inch per coat) of SEMCO Liquid Membrane™ with brush or roller over substrate including pre-treated areas. Once you can walk on the surface and not get any residue on your shoe or feet or cannot leave a fingerprint impression it is ready to re-coat. Apply another thin coat of SEMCO Liquid Membrane™ in an alternate direction over the first coat of SEMCO Liquid Membrane™. Let topcoat dry to the touch, approximately 1–2 hours at 70 °F (21 °C) and 50% RH. When last coat has dried to the touch, inspect final surface for pinholes, voids, thin spots or other defects.SEMCO Liquid Membrane™ will dry to a lighter color when it’s dry to touch. Use additional SEMCO Liquid Membrane™ to seal the defects. Required total thickness is 0.03 - 0.04 inches for non submerged applications.
Curing Time
Curing time depends on temperature, humidity and airflow, however typically initial cure is within 6 - 7 days as per specific product recommendations.
Additional Information
• For clean up use warm water to clean brush or roller right after use. • For optimal bonding we highly recommend preparing the surface as mentioned above for best results. • Stir up the product well before use in order to mix up the color pigments. • Avoid application in direct sun light in the afternoon or temperatures of over 85F as it might cause the product to dry too fast before it can adhere to the substrate • Suitable for light foot traffic.For heavy foot traffic or vehicle traffic, we recommend using SEMCO Titan Shield Gloss. • It can not be applied to wet substrates or substrates still containing moisture, else it will not cure correctly and stay tacky. Max. rest moisture in substrate can be up to 3%. If you are unsure about the moisture content, have it measured prior to application. • Ensuring that a surface is pH balanced before applying a coating is crucial for optimal adhesion and performance. Therefore we recommend our preparation methods for optimal adhesion. We do not recommend acid washes. • For applications where the product is fully submerged, 3 coats @20mil each is required and allow a curing time of minimum 6-7 days.Also application must coat entire surface to above the waterline. • Please note that the SEMCO Liquid Membrane may experience slight color variations or discoloration when exposed to water for extended periods of time. • Application on non porous surfaces such as metal or fiberglass : Apply thin coats as this will allow for the product to cure faster. • Cure times are displayed in our curing chart. However if coats have been applied too thick, the surface might feel tacky. This is a sign of trapped moisture. If you have left over product, apply a very thin coat over the entire surface. The surface needs to be fully cured and hard before permitting water. • For applications where SEMCO Liquid Membrane™ is applied on pool plaster, extended curing times might occur as plaster holds more moisture which needs to breath out first. A slight color change may occur when being in contact with water when the product has not fully cured yet. This however will not affect the performance of the SEMCO Liquid Membrane™. • It is always advisable to apply a small test patch in an inconspicuous are to ensure adequate adhesion prior to full application. • If you have multiple containers of SEMCO Liquid Membrane™, we highly recommend to either mix them together or use one container for the last layer to get color consistency.

PRESTAIN APPLICATION
• Apply PreStain Color with sponge, brush, foam roller or airless sprayer with tip size 17 • Apply thin and even coats on to concrete. Do not overload application tool with product and avoid leaving puddles on the surface. • Repeat application if more color saturation is required. • Let it dry for 12 - 24 hours depending on temperature before applying sealer for added protection.
Additional Information
• Must apply between 40-90˚F (4.5-32˚C). Do not use if rain is expected within 24 hours. The concrete surface must be completely dry before application. • Work in small sections lightly saturating the surface and immediately back-brush or use pad applicator to eliminate puddling, remove excess and evenly distribute PreStain. • Over application of stain will lead to surface failure including peeling and cracking. • Stir up the product well before use in order to mix up the color pigments. • For areas with furniture or heavy foot traffic we recommend using Titan Shield Sealer to protect the surface.
Prepare your Non-Skid Additive
• Lightly shake the Non-Skid container prior to mixing • Empty Non-Skid container into Titan Shield Gloss sealer and mix up well.
Titan Shield Application
Use a 1/2" woven nap roller to apply Titan Shield Gloss. Apply the first coat and allow the sealer to dry for at least 30 - 45 minutes, up to 2 hrs in high humidity conditions, or until surface is completely dry. Repeat the application to a minimum of 3 coats or a total thickness of 15-20 mil. Additional coats may be required depending on the porosity of your substrate. For larger areas Titan Shield Gloss can be applied with an airless sprayer with tip size 17. Adjust the sprayer to the lowest possible air setting and try out on a test area first.
Additional Information
• If Non-Skid Additive is used with clear Titan Shield, spray application is recommended • For roller application Titan Shield with color is recommended • Avoid application in direct sun light in the afternoon or temperatures of over 85F as it might cause the product to dry too fast before it can adhere to the substrate • It can not be applied to wet substrates or substrates still containing moisture, else it will not cure correctly and stay tacky. Max. rest moisture in substrate can be up to 3%. If you are unsure about the moisture content, have it measured prior to application. • Cure times are displayed in our curing chart.
Easy Application
Ensure your surface is free of any debris. Gather all the products and tools needed for your project. • If there are any existing wax coatings, please remove prior to application • Use household microfiber mop for application • Pour small amount onto clean surface apply thin coat with microfiber mop. Apply small sections at a time. On wood floors or laminate flooring, apply in the directions of the individual planks.
Additional Information
• If you miss a spot, wait until floor is dry and pour Crystal Coat onto clean microfiber cloth and touch up spot. • Only use when temperatures are above 50F. Allow to dry for 45 minutes before walking on the floor. • Only place heavy objects once surface has cured for 24 hours. • A 2nd coat can be applied if desired. Apply only once floor is dry enough to walk on without any imprints.

• For Cement / Hardiebacker board applications, ensure that boards are properly installed and sound.
Fabric Reinforcement
For any joints between the boards and the joint between floor and wall, we recommend using the Fabric Reinforcement. To apply the Fabric Reinforcement, apply a generous coat of SEMCO Liquid Membrane™ over the crack. Put the Fabric Reinforcement on a press it flat, after 10-15 min apply another coat of SEMCO Liquid Membrane™ over the Fabric Reinforcement to encapsulate it. Let it dry to the touch before applying SEMCO Liquid Membrane™ over the entire surface.
Masking
Mask off areas that are not receiving any coating. Remove masking tape before material has fully cured.
APPLYING COAT
Use a 1/2" nap roller. Allow any pre-treated areas to fully dry. Apply a thin coat (0.015 inch per coat) of SEMCO Liquid Membrane™ with brush or roller over substrate including pre-treated areas. Once you can walk on the surface and not get any residue on your shoe or feet or cannot leave a fingerprint impression it is ready to re-coat. Apply another thin coat of SEMCO Liquid Membrane™ in an alternate direction over the first coat of SEMCO Liquid Membrane™. Let topcoat dry to the touch, approximately 1–2 hours at 70 °F (21 °C) and 50% RH. When last coat has dried to the touch, inspect final surface for pinholes, voids, thin spots or other defects.SEMCO Liquid Membrane™ will dry to a lighter color when it’s dry to touch. Use additional SEMCO Liquid Membrane™ to seal the defects. Required total thickness is 0.03 - 0.04 inches for non submerged applications.
Curing Time
Curing time depends on temperature, humidity and airflow, however typically initial cure is within 6 - 7 days as per specific product recommendations. If SEMCO Liquid Membrane is used as a primary waterproofing, you can tile over the next day with regular tile adhesive of your choice.

Therefore we recommend our preparation methods for optimal adhesion. We do not recommend acid washes. • For applications where the product is fully submerged, 3 coats @20mil each is required and allow a curing time of minimum 6-7 days.Also application must coat entire surface to above the waterline. • Application on non porous surfaces such as metal or fiberglass : Apply thin coats as this will allow for the product to cure faster. • Cure times are displayed in our curing chart. However if coats have been applied too thick, the surface might feel tacky. This is a sign of trapped moisture. If you have left over product, apply a very thin coat over the entire surface. The surface needs to be fully cured and hard before permitting water. • For applications where SEMCO Liquid Membrane™ is applied on pool plaster, extended curing times might occur as plaster holds more moisture which needs to breath out first. A slight color change may occur when being in contact with water when the product has not fully cured yet. This however will not affect the performance of the SEMCO Liquid Membrane™. • It is always advisable to apply a small test patch in an inconspicuous are to ensure adequate adhesion prior to full application. • If you have multiple containers of SEMCO Liquid Membrane™, we highly recommend to either mix them together or use one container for the last layer to get color consistency.
