Frequently Asked Questions
If the paint film of the antiviral mineral coating is damaged (e.g., scratched, cracked, or in contact with acidic substances), will the antiviral/antibacterial performance in that area be affected?
Yes. The antiviral/antibacterial effect of the coating depends on the integrity of the paint film. If the film is locally damaged by mechanical action (scratches, cracks, impact) or eroded by acidic/alkaline/solvent substances, the functionality in that area will decrease significantly or even be lost.
Recommended steps for remediation:
- Remove the damaged or powdery coating.
- Repair the substrate as needed, allow it to dry, and sand it smooth.
- Reapply the antiviral mineral coating (1–2 coats) to the repaired area to restore film continuity and integrity. The antiviral/antibacterial effect will then be reinstated.
Is the antiviral mineral coating suitable for high-humidity environments like bathrooms, and how does humidity affect its performance?
The antiviral mineral coating is designed for indoor inorganic substrates such as cement and calcium silicate board walls. For high-humidity spaces like bathrooms:
- It can be applied to walls that are not directly exposed to prolonged water contact (e.g., walls outside the shower area, walls above the sink), provided ventilation is good and the substrate is dry.
- It is not recommended for areas under constant direct water exposure or where water accumulates (e.g., inside shower enclosures, bathtub rims with frequent water contact), as persistent moisture may reduce the durability and function of the coating and substrate.
- In environments with sustained high humidity but no standing water, if the coating remains dry and free of mold, its antiviral/antibacterial and mold-resistant properties can still function. If walls show persistent condensation or mold growth, address the moisture source first; a full renovation may be required if necessary.
If water or other media are accidentally added to the antiviral mineral coating during application, will it affect the antiviral performance and warranty?
The technical data sheet specifies that the coating should be applied as supplied, without dilution.
If water or other media are added during application:
- It may lead to insufficient film thickness, altered pore structure, and reduced antiviral/antibacterial and protective performance.
- It may also cause issues such as poor opacity and weakened adhesion.
Therefore, any dilution or mixing not approved by the manufacturer is strongly discouraged. Such modifications are not covered under the manufacturer’s quality assurance or warranty.
What is the best way to remove the coating if it accidentally gets on furniture or flooring, especially after drying?
The antiviral mineral coating is water-based. Cleaning methods are as follows:
- If still wet: Wipe promptly with a wet cloth or sponge using clean water. A small amount of neutral cleaner may be added if necessary.
- If dried:
- Gently lift the film using a plastic or wooden scraper. Avoid metal tools to prevent damaging the surface.
- For wood or tile floors, applying warm water or covering with a damp cloth for a short time can soften the film for easier removal.
- Do not use strong solvents (e.g., lacquer thinner, toluene) directly on furniture or plastic surfaces, as they may cause discoloration, stickiness, or coating damage.
The coating works best on inorganic substrates like calcium silicate boards and cement plaster. What surface preparation is required for non-ideal substrates such as previously painted walls or wooden boards?
Previously painted walls:
- Check adhesion of existing paint. Remove loose, peeling, blistering, or powdery areas down to a sound substrate.
- Clean off grease, smoke residue, mold, and dust. A neutral cleaner may be used; ensure the surface is completely dry.
- Fill cracks and holes with suitable interior filler, let dry, and sand smooth.
- Depending on absorbency and smoothness, apply a sealing or adhesion-promoting water-based primer to minimize color and absorption differences.
- Apply one coat of undiluted antiviral mineral coating as primer, followed by 1–2 topcoats.
Wooden boards (e.g., plywood, wood-based panels):
- Sand the surface smooth and remove dust. Seal knots and resinous areas if needed.
- Apply a suitable wood sealer/primer (preferably water-based) to seal pores and prevent resin bleed.
- If leveling is required, use a low-shrinkage wood filler, let dry completely, and sand smooth.
- Apply one coat of antiviral mineral coating as primer, then 1–2 topcoats.
For non-standard substrates, always test on a small area first to confirm adhesion and appearance.
Does cleaning the coating with general cleaners or soapy water affect its antiviral performance?
Routine cleaning with diluted neutral cleaners or soapy water using a soft cloth will not significantly impair the coating’s antiviral function. Keeping the surface clean and dry helps maintain its performance.
Important notes:
- Avoid prolonged or repeated use of strong acids, alkalis, disinfectants, high-alcohol solutions, or solvents, as they may damage the film.
- Do not use abrasive cleaners or rough pads, which can wear down the coating and reduce its effectiveness.
If the film is damaged due to improper cleaning, repair it following the method described in point 4.
Is there a return or exchange policy? What are the terms?
- Keep your purchase receipt. Returns/exchanges must be processed through the original purchase channel (distributor, store, or platform) in accordance with local policies.
- Only unopened, undamaged, and original products in their original packaging are eligible. Opened, custom-colored, or non-genuine products are not eligible.
- For confirmed quality defects (e.g., severe clumping, spoilage), the manufacturer’s quality team will assess and handle according to official policies.
Is periodic recoating needed to maintain the antiviral effect? What is the recommended frequency?
The coating’s antiviral and mold-resistant properties are inherent to its inorganic mineral film. If the film remains intact, dry, and free of heavy soiling, recoating is generally driven by aesthetic or wear considerations rather than functional decay. In typical indoor residential settings, a full repaint cycle is often around 5 years, adjustable based on actual conditions. No fixed recoating schedule is required solely for antiviral maintenance.
Does the Continental Coatings Architecture series have a shelf life? How long can it be stored after opening?
The Architecture series is a water-based coating. Unopened and stored under normal conditions (cool, dry, away from sunlight and freezing), it has a shelf life of 2 years. Refer to the batch number and labeling on the container for specifics.
Does the antiviral/antibacterial protection of Continental Antiviral Mineral Coating expire?
The coating works by using its alkaline, porous film to adsorb and neutralize viruses and bacteria. Under normal indoor conditions with the film intact, clean, and dry, the effect is designed to be long-lasting without a set expiration date. Actual performance can be influenced by environmental factors (e.g., heavy soiling, chemical exposure, prolonged dampness) and film damage. Laboratory test reports provide the basis for the stated antiviral/bacterial efficacy, which is not intended for medical or therapeutic use.
How can consumers verify product authenticity and avoid counterfeits?
Purchase only through authorized channels: manufacturer-authorized distributors, official online stores, or partnered platforms.
Check for:
- Complete packaging with clear Continental branding, product name, model, batch number, and production date.
- Legible Chinese/English labels listing key ingredients, uses, application instructions, and safety notes without signs of tampering.
- Intact, unbroken seals on unopened containers.
If in doubt, share container photos and batch numbers with the manufacturer or general distributor for verification. Avoid products from unclear sources or with suspiciously low prices.
