Stone Soap
- What it is: A concentrated, pH-neutral, biodegradable heavy-duty cleaner that removes dirt, grime, mineral deposits, and efflorescence without damaging finished or unfinished surfaces.
- Best for: Prepping concrete, natural stone, tile, and grout before applying any SEMCO sealer, stain, or waterproofing product — and for general surface cleaning and maintenance.
- Stands out because: Neutral pH means no acid-etch damage or adhesion-killing residue, works in hard or soft water, and is 100% biodegradable and safe for confined spaces.
- Keep in mind: It's a cleaner, not an acid etch — for surfaces that genuinely need chemical etching, SEMCO's guidance is still to avoid muriatic acid, since acid residue is a common cause of coating adhesion failure.
- Keep in mind: It's a rejuvenating topcoat, not a structural repair or a permanent refinish — expect to recoat periodically to maintain the shine, and always test on an inconspicuous area first.
Size:1 Quart (up to 250 sq ft)
Quantity:
- Cleans without damaging the surface. A concentrated, neutral-pH formula that lifts dirt and grime without etching, discoloring, or degrading finished surfaces the way acidic cleaners can.
- The right prep step for every SEMCO coating. Whether you're about to apply SEMCO Liquid Membrane, PreStain Color, Titan Shield Gloss, Natural Shield, or Sealer Matte, Stone Soap (often paired with Nu-Lift Cleaner or Power Cleaner depending on the substrate) is the recommended first step.
- Works in hard or soft water. Performance doesn't depend on your local water chemistry.
- 100% biodegradable. Breaks down naturally and is safe to use in confined or occupied spaces.
- No harsh rinsing chemicals required. Simple dilution with water, applied with a standard pump sprayer.
- One of SEMCO's founding products. Part of the original three-product lineup the company launched with in 1991 — over three decades of use in the field.
Cleaning Performance
- Concentrated, heavy-duty formula that removes dirt, grime, mineral deposits, and efflorescence.
- Neutral pH — won't etch or damage finished or delicate surfaces.
- Equally effective in hard or soft water.
Health & Environmental
- 100% biodegradable.
- Can be safely used in confined environments.
- User-friendly, environmentally-responsible formula.
Practical Use
- Doesn't need to be rinsed off to remain effective, though rinsing before coating is still recommended.
- Simple dilution ratio and application with a standard pump sprayer.
- Suitable for countertops, floors, concrete, stone, tile, and more.
- Concrete and masonry surfaces — remove mineral deposits and efflorescence before applying a sealer, stain, or waterproofing membrane.
- Natural stone and ceramic tile/grout — clean without etching or dulling the finish.
- Existing sealed or coated surfaces — general cleaning and maintenance without degrading the existing finish.
- Prep before SEMCO Liquid Membrane, PreStain Color, Titan Shield Gloss, Natural Shield, or Sealer Matte — the standard first-step cleaner in SEMCO's surface-prep process (often paired with Nu-Lift Cleaner for mineral deposits/efflorescence, or Power Cleaner where there's oil or grease).
- Countertops, floors, and general household/commercial surfaces — everyday cleaning beyond just pre-coating prep.
- Gather materials and prep the space. Ensure the surface is free of debris.
- Mix the solution. Combine 1 part Stone Soap with 4 parts water.
- Pre-dampen the surface with plain water — this keeps the cleaner from penetrating too deep into the substrate's pores.
- Apply the Stone Soap mixture lightly with a pump sprayer and let it sit for 2–3 minutes.
- Scrub the surface using a scrub machine or nylon brush.
- Rinse thoroughly, making sure no residue is left behind.
- Let the surface fully dry before applying any sealer or coating.
Additional notes: Do not use muriatic acid to prep surfaces — acid residue can cause coating adhesion problems. Getting a surface properly pH-balanced before coating is critical for adhesion and performance, which is why SEMCO recommends its standard prep methods (like Stone Soap) over acid washes.
PRODUCT INFO
SEMCO Stone Soap is a highly concentrated, heavy-duty, pH-neutral cleaner built to strip dirt, grime, mineral deposits, and efflorescence from a surface without harming or etching what's underneath. Unlike acid washes, it won't leave behind residues that compromise adhesion, and unlike many commercial degreasers, it's 100% biodegradable and gentle enough for confined spaces.
It's one of SEMCO's three original products — Stone Soap, Power Cleaner, and Nu-Lift Cleaner were the company's founding lineup back in 1991 — and it remains the standard first step in prepping concrete, natural stone, tile, and other surfaces before applying SEMCO Liquid Membrane, PreStain Color, Titan Shield Gloss, or any other sealer in the lineup. It works equally well in hard or soft water and doesn't require rinsing to remain effective, though rinsing is still recommended before coating.

- Application tools – Pump sprayer, scrub machine or nylon brush
- Shelf life – 2 years in controlled ambient storage (60–72°F)
How Stone Soap Compares to Other Surface-Prep Methods
Stone Soap is positioned specifically as a safer alternative to acid-based surface prep. Here's how a neutral-pH cleaner concentrate compares to the other common surface-prep chemistries, based on published, sourced information (not a specific named competing product).
| SEMCO Stone Soap (Neutral-pH Cleaner Concentrate) |
Muriatic Acid Wash | Solvent-Based Degreaser | |
|---|---|---|---|
| pH | Neutral | Strongly acidic; requires neutralization after use | Not pH-based; strong solvent chemistry |
| Risk of adhesion failure from residue | Low — no acid residue to trap in pores | Real risk — residual chloride salts and unneutralized acid can cause osmotic blistering and adhesion failure under coatings | Can leave oily residue if not fully rinsed |
| Safe for finished/delicate surfaces | ✓ | ✗ Etches and can damage finished surfaces |
Varies — can dull or discolor some finishes |
| Biodegradable | ✓ 100% |
✗ Hazardous waste disposal considerations for acid rinse water |
✗ |
| Safe for confined spaces | ✓ | ✗ Fumes require ventilation and PPE |
✗ Solvent fumes require ventilation |
| Rinse required | Recommended before coating, not required for effectiveness | Required, and must be fully neutralized, not just rinsed | Required |
This comparison reflects general, publicly available information about surface-prep chemistries as a category, not a specific competing branded product.

Step by step
FOR STEP-BY-STEP GUIDES SPECIFIC TO YOUR PROJECT
-
1
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.If you need assistance with which cleaners are needed for the Prep, feel free to use our live chat or call us! -

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. -

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.

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.

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. -

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. 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.
