  • Won't change how your surface looks. No gloss, no color shift — just added protection, so your concrete, stone, or stucco still looks like itself.
  • Deeper protection, longer lasting. 6x more active ingredients than typical penetrating sealers, penetrating into the pores instead of sitting on top.
  • Works where other sealers can't. Safe to apply on damp surfaces — it can even help dry out a damp substrate before other coatings go on.
  • Stops the damage that adds up over time. Guards against freeze-thaw cracking, efflorescence, and mold or mildew staining.

Reduces Freeze Thaw Damage
Penetrating Sealer
Low Odor & Low VOC
Made in USA
  • Durability. Penetrates into the pores and stabilizes the substrate from within, prolonging the life span of the surface and reducing long-term maintenance.
  • UV and alkali resistance. UV-resistant and highly alkali-resistant, with effective protection against freeze-thaw damage.
  • Built for commercial and industrial use. Excellent chemical resistance and an industrial-strength finish suited to demanding commercial and industrial environments, not just residential touch-ups.
  • A real waterproofing sealer. Low water permeability makes it suitable for wet rooms and showers, and it can be applied to damp surfaces where many sealers can’t
    be used.
  • Extends the life of what you already have. Protects the investment in existing mortar, tile, stucco, brick, and natural stone rather than requiring a full resurface.
  • Reduces efflorescence and staining. Enhanced water beading, reduced
    efflorescence, and protection against stains caused by mold and mildew.
  • No change in appearance. The treated surface doesn’t become glossy — it stays tackfree with a natural, unsealed look and feel.
  • Easy application and clean-up. Apply with an airless sprayer, pump sprayer, or
    roller; clean up with SEMCO Stone Soap and water.
  • Protects without changing the look of your surface. Natural Shield penetrates into the pores rather than forming a film on top, so treated concrete, stone, or block keeps
    its natural color, texture, and matte finish — nothing looks “sealed.”
  • 6x more active ingredients than most penetrating sealers. A more concentrated formula means deeper penetration and longer-lasting protection compared to typical
    off-the-shelf penetrating sealers.
  • Fights the damage moisture causes over time. Reduces water absorption enough to help prevent freeze-thaw cracking, pitting, spalling, and alkali-silica reaction (ASR) damage in concrete and masonry.
  • Works on damp surfaces, even mitigates moisture. Unlike most sealers, Natural Shield tolerates damp substrates and is even used on its own to help mitigate constant dampness before other coatings are applied.
  • Commercial and industrial grade, DIY-simple application. Delivers solvent-basedlevel performance and chemical resistance, but goes on with a roller or sprayer and cleans up with water.
  • Protects a wide range of surfaces, not just concrete. Suited to existing concrete, stucco, porous natural stone, slump block, tilt-up walls, and X-Bond Microcement - one product across most of a property’s exterior masonry.
  • Existing concrete. Penetrates weathered or previously uncoated concrete to reinforce and stabilize it from within, extending the life of older slabs without changing their appearance.
  • Stucco. Soaks into porous stucco to reduce water absorption and efflorescence while keeping the original textured look fully intact.
  • Porous natural stone. Protects natural stone’s pores against water intrusion and staining without adding shine, preserving the stone’s natural texture and color.
  • Slump block. Seals the highly porous surface of slump block against moisture penetration and efflorescence - common in retaining walls and garden walls.
  • Block wall and tilt-up wall. Bonds into vertical masonry and tilt-up concrete panels to repel water and resist freeze-thaw cracking, pitting, and spalling over time.
  • PreStain finishes. Locks in stained concrete color while adding water and stain resistance, without adding the gloss that would alter the stain’s natural look.
  • Cinder block. Works well on cinder block walls to repel water and reduce efflorescence - though cracks wider than hairline need to be filled first, since Natural Shield does not bridge cracks the way a membrane does.
  • Brick. Penetrates brick and mortar joints to reduce water absorption and protect against freeze-thaw damage and mold or mildew staining.
  • Not recommended for: painted surfaces (the sealer needs open pores to penetrate) or areas with heavy foot or vehicle traffic — for those, SEMCO recommends Titan Shield Gloss instead.
  • Ideal projects: exterior stucco and masonry walls, retaining walls, natural stone patios and facades, garden and block walls, brick veneer, existing concrete slabs, showers and wet rooms, and as a moisture-mitigation pre-treatment ahead of other SEMCO coatings.
  1. Prep the surface. Sweep all debris off the surface. For concrete or brick, remove mineral deposits or efflorescence first with Nu-Lift Cleaner and Stone Soap. The surface must have open pores — Natural Shield cannot penetrate a painted or
    previously coated surface.
  2. Fill any cracks first. Natural Shield does not bridge or span cracks, so cracks need to be filled before application.
  3. Apply the first coat with a 1/4" nap roller, HVLP sprayer, pump sprayer, or airless sprayer (tip size 15 at roughly 400 PSI). Avoid letting the product puddle - puddling causes a white haze.
  4. Apply the second and third coats without letting the sealer dry in between. This is the opposite of a topical sealer: Natural Shield needs to stay wet through all 3 coats to bond and penetrate properly.
  5. Apply a minimum of 3 coats. More porous surfaces such as concrete or block may need additional coats.
  6. On vertical surfaces, apply from bottom to top to avoid runs, and avoid overspray.
  7. Let it dry and cure. Dry to the touch in about 30 minutes at 72°F; full cure takes about 7 days at 72°F (as fast as 4 days at 100°F).

Good to know: Avoid application in direct afternoon sun or above 85°F. Clean tools with warm water (and Stone Soap, if needed) right after use.

PRODUCT INFO

Engineered for professionals. Easy enough to apply yourself.

Natural Shield is a ready-to-use, water-based penetrating sealer built for concrete, masonry, stucco, and natural stone. Unlike a topical sealer that sits on top of the surface, Natural Shield’s low molecular weight lets it soak into the pores of the substrate, where a chemical reaction creates a solid, breathable membrane from within. The result is durability and performance that matches a solvent-based system, with the easy application and water clean-up of a water-based product.

Because it penetrates rather than coats, Natural Shield leaves your surface’s natural look completely intact — no gloss, no color change, no shift in texture. That makes it the go-to choice for protecting existing concrete, stucco, block walls, and natural stone from water intrusion, efflorescence, and freeze-thaw damage, in both commercial and industrial settings, without changing how the surface looks or feels.

  • Type – Water based Silane and siloxane
  • Coats required – Minimum 3 coats, applied wet-on-wet (do not let the sealer dry between coats 1-3)
  • Coverage – 150–350 sq ft per gallon (3 coats)
  • Application tools – 1/4" nap roller, HVLP sprayer, pump sprayer, or airless sprayer
  • Application temperature – 50°F to 90°F
  • Dry time – only ~10-30 minutes needed between coats at 72°F
  • Cure time – 7 days at 72°F (as fast as 4 days at 100°F)
  • Shelf life – 2 years in controlled ambient storage (60–72°F)

Laboratory test results: water - excellent; alkali resistance - excellent;
used motor oil - good;
transmission fluid - good;
10% hydraulic acid - good.
Application notes: Do not allow the sealer to puddle during application - puddling causes a white haze. Do not apply over an existing coating; the surface needs open pores for Natural Shield to penetrate. On vertical surfaces, apply from bottom to top to avoid runs, and avoid overspray.

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.

3

Masking

Mask off areas that are not receiving any coating. Remove masking tape before material has fully cured.

4

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.

5

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.

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.

• 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.
• 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.
