## Frequently asked questions

### Choosing a Product

- **How do I know which DuraCore product is right for my project?** Start by identifying what you want the concrete to do: become harder, resist moisture, repel stains, or improve appearance. Each DuraCore product is designed around one of these outcomes.
- **What's the difference between a densifier and a moisture control treatment?** A densifier strengthens concrete internally, while a moisture control treatment reduces moisture movement within the slab.
- **How do densifiers compare to sealers?** Densifiers work inside the concrete to make it harder. Sealers work on the surface to protect appearance and improve cleanability.
- **When should I use a penetrating repeller instead of a surface sealer?** Use a penetrating repeller when you want protection without altering the concrete's appearance or sheen.
- **Which product is best for driveways and outdoor areas?** A penetrating repeller is usually the best option for outdoor areas, especially driveways.
- **Which product should I use before laying flooring?** Choose a moisture control treatment - the correct one depends on timing and moisture conditions.
- **What's the difference between Moisture Proof and Moisture Prevention?** Moisture Proof treats existing or active moisture issues; Moisture Prevention is applied early to reduce future risk.
- **Can I combine more than one DuraCore product on the same slab?** Yes, as long as the products serve different purposes and are applied in the correct order.
- **Can I use a densifier and a repeller on the same surface?** Yes - this is a common combination when you want both strength and repellency.
- **How do I choose between AquaSeal and Lustre Crete?** AquaSeal gives a low-sheen protective finish; Lustre Crete enhances colour and provides a richer decorative look.
- **Do I need a moisture treatment on every slab?** Not always - only slabs that will receive flooring or have known moisture issues typically need treatment.
- **Which product should I use to reduce dusting?** A densifier such as DensiCrete is the best choice for reducing dusting on concrete surfaces.
- **Can I use DensiCrete on decorative or coloured concrete?** Yes - densifiers are safe for decorative, coloured, stamped or integrally coloured concrete.
- **Which product provides the most stain resistance?** A penetrating repeller provides the most effective protection against staining.
- **Are DuraCore products suitable for polished concrete floors?** Yes - densifiers and certain sealers are commonly used in polished concrete systems.
- **Are any products better suited for high-traffic commercial areas?** Yes - densifiers and densifier/repeller combinations are ideal for high-wear environments.
- **Are any products safe to use indoors?** Yes - all DuraCore penetrating products are low-VOC and suitable for indoor use.

### Application & Preparation

- **How clean does the surface need to be before applying a DuraCore product?** The surface must be clean, unsealed, and free of anything that would stop the product from penetrating.
- **Can I apply these products to old concrete?** Yes - most DuraCore products work well on older concrete as long as it's clean, open, and absorbent.
- **Can I apply products to new concrete? How long should I wait?** Yes - most products can be applied to new concrete once the slab is hard enough for foot traffic and free water has evaporated.
- **Do I need to grind the concrete before applying any products?** Only if the surface is sealed, coated, contaminated, or too dense to absorb the product properly.
- **What tools or equipment do I need for application?** Most DuraCore products can be applied with simple sprayers, rollers, brooms, or microfibre pads.
- **How do I know if the product has absorbed properly?** The surface will stop looking wet and will no longer accept more material.
- **What should I do if residue remains after application?** Most residue can be removed by rinsing, autoscrubbing, or buffing, depending on the product.
- **Can I apply a sealer after using a densifier?** Yes - this is common in polished, decorative, or high-finish applications.
- **Do DuraCore products work on burnished concrete?** Partially - very tight, burnished surfaces absorb less product, reducing effectiveness.
- **What weather conditions are best for applying products?** Mild conditions with stable temperature and no rain forecast.
- **Can I apply products if rain is forecast?** Avoid applying penetrating products if rain may hit the surface before they have absorbed.
- **Can I apply products in very hot or cold temperatures?** Extremes of temperature can affect absorption, curing, and overall performance.
- **What happens if the product dries too quickly?** Rapid drying can reduce penetration and lead to uneven performance.
- **Can I use a pressure washer before or after application?** Before - yes. After - generally not recommended for a few days.
- **How soon can the treated area be walked on?** Most areas can be walked on within a few hours, depending on the product.
- **Can I drive on the surface after treatment?** Yes, but only after full cure, especially for sealers.
- **What is the recommended drying time between coats?** Drying time depends on product type but is usually 1-4 hours.
- **Do I need to mask or protect surrounding surfaces?** Yes - most products can mark or react with glass, aluminium or painted surfaces if left on them.
- **Will these products damage glass or aluminium?** Some products can etch or leave residue if left on sensitive surfaces.
- **Can I apply treatments over painted or coated surfaces?** No - penetrating products cannot absorb through paint or coatings.
- **Do I need to remove old sealers before applying a DuraCore product?** Yes - old sealers prevent penetration and must be removed.
- **How do I clean tools after application?** Most tools can be cleaned with water immediately after use.

### Moisture, Vapour & Slab Performance

- **What is moisture vapour transmission (MVT)?** Moisture vapour transmission is the movement of water vapour through concrete. All slabs release moisture, but high levels can cause flooring and coating failures.
- **How do I know if my slab has a moisture problem?** You know by testing. Visual signs help, but moisture readings are the reliable method.
- **What causes flooring adhesives to fail on concrete slabs?** The most common cause is excessive moisture vapour moving through the slab.
- **Do I still need a moisture membrane if I use Moisture Proof?** Moisture Proof reduces moisture vapour movement but is not a substitute for a building-code-required membrane.
- **Can Moisture Proof be used under timber, vinyl or carpet?** Yes - Moisture Proof is designed specifically to support most flooring systems.
- **How long after applying Moisture Proof can flooring be installed?** Usually the next day, depending on drying conditions.
- **How do I test moisture levels in concrete?** Use a recognised testing method such as RH probes, moisture metres or calcium chloride tests.
- **Does weather affect moisture levels in concrete?** Yes - ambient humidity, temperature and rainfall significantly influence moisture movement.
- **Can moisture treatments fix flooring failures?** They can help stabilise the slab for future work, but they cannot reverse damage already done.
- **Can moisture treatments replace plastic membranes under slabs?** No - moisture treatments support performance but do not replace code-required membranes.
- **Will DuraCore moisture treatments change the appearance of the slab?** No - they are penetrating treatments and do not form a film or alter appearance.
- **Are moisture treatments suitable for basements or below-grade slabs?** Yes - but they only address vapour movement, not liquid water pressure.
- **Can moisture treatments be used outdoors?** Yes, but they are typically designed for indoor flooring preparation.
- **Do densifiers help with moisture issues?** Not directly. Densifiers improve hardness but do not reliably control moisture vapour transmission.
- **What's the difference between moisture curing, drying and sealing?** Curing keeps moisture in new concrete; drying removes excess moisture; sealing protects the surface.
- **Why does new concrete hold so much moisture?** Because concrete contains large amounts of water for hydration and continues to release it as it dries.

### Densifiers (Science & Use)

- **What is a concrete densifier?** A densifier is a penetrating treatment that reacts inside concrete to make it harder, stronger and more resistant to dusting and wear.
- **Can densifiers be used on polished concrete?** Yes - densifiers are an essential step in most polished concrete systems.
- **Do densifiers help prevent dusting?** Yes - densifiers are one of the most effective ways to reduce dusting on concrete.
- **How do densifiers work chemically?** Densifiers react with calcium hydroxide in the concrete to create more C-S-H, which fills microscopic voids and strengthens the slab.
- **Will densifiers make concrete shiny?** Not by themselves. Densifiers increase hardness but do not create shine - polishing equipment does.
- **Do densifiers stop concrete from absorbing water?** No - densifiers reduce porosity but do not create water repellency.
- **Do densifiers improve scratch resistance?** Yes - densifiers harden the surface, which reduces scratching and abrasion.
- **How long does it take for densification to fully occur?** The slab hardens gradually over several days, but initial benefits appear within hours.
- **Can densifiers be used on coloured or decorative concrete?** Yes - densifiers are fully compatible with integrally coloured or decorative concrete.
- **Is one application of densifier enough?** Usually yes, but highly porous or weak surfaces may benefit from a second application.
- **Can densifiers be overapplied?** Yes - overapplication can leave residue or white deposits on the surface.

### Repellers & Stain Protection

- **What stains do penetrating repellers protect against?** Repellers protect concrete from water-based and oil-based stains, including food, grease, dirt, and everyday contaminants.
- **Do repellers change the colour of concrete?** No - penetrating repellers do not alter the colour or gloss of the concrete.
- **How long do repellers last?** Repellers typically last several years, depending on exposure and traffic.
- **Can repellers be used under a surface sealer?** Generally no - repellers make the surface hydrophobic, which prevents sealers from bonding properly.
- **Will repellers make concrete slippery?** No - repellers do not change the texture of the surface, so slip resistance remains the same.
- **Will oil still leave marks even with a repeller applied?** Possibly - repellers slow absorption and make cleanup easier, but they do not make concrete completely stain-proof.
- **How soon can repellers be exposed to water or oil?** Repellers usually reach basic effectiveness within a few hours and full performance within 24-48 hours.
- **Do repellers need maintenance or reapplication?** Yes - like all repellency treatments, they lose effectiveness over time.

### Sealers & Surface Coatings

- **What is the difference between AquaSeal and Lustre Crete?** AquaSeal provides a low-sheen protective finish; Lustre Crete enhances colour and adds a more decorative appearance.
- **Can sealers be used outdoors?** AquaSeal can be used outdoors; Lustre Crete is better suited for internal or semi-protected areas.
- **Can I apply sealer over a previous coating?** Only if the coating is compatible - many sealers require a fully stripped surface for proper adhesion.
- **Do sealers make concrete glossy?** Some sealers add sheen, but most DuraCore film-forming products are designed for low or moderate gloss.
- **How many coats of sealer do I need?** Most sealers require two thin coats for even coverage and best appearance.
- **Will sealers yellow in the sun?** AquaSeal is UV stable, but Lustre Crete may show slight changes if used in high UV areas.
- **How long do sealers last before reapplication is needed?** Typically 1-3 years depending on traffic, exposure and cleaning habits.
- **Do sealers protect against tyre marks?** They help reduce tyre marking but cannot eliminate it completely, especially in hot conditions.

### Appearance, Finishes & Aesthetics

- **Will DuraCore products change the appearance of the concrete?** Most DuraCore products do not change the appearance of concrete. Only the sealers (AquaSeal and Lustre Crete) are designed to enhance the visual finish.
- **Can sealers enhance colour or make the slab look richer?** Yes - sealers can subtly or noticeably enhance colour depending on the product.
- **Will densifiers or moisture treatments alter the colour?** No - densifiers and moisture treatments are invisible once dry.
- **Can products be used on exposed aggregate?** Yes - repellers and sealers work well on exposed aggregate, depending on the desired finish.
- **Are treatments visible on the surface once dry?** Penetrating treatments are invisible. Only sealers leave a visible film.
- **How do I achieve a natural look without gloss?** Use a penetrating repeller - it protects the surface without altering appearance.
- **Will these products help with efflorescence?** Densifiers and moisture treatments can help reduce efflorescence by limiting moisture movement, but they cannot eliminate external sources of salts.

### Durability, Lifetime & Performance

- **How long do DuraCore treatments last?** Penetrating treatments last for the life of the slab. Surface sealers require periodic reapplication.
- **Do I ever need to reapply densifiers?** Not usually - densifiers are considered permanent.
- **How do DuraCore products perform in extreme weather?** Penetrating treatments handle extreme temperatures well; film-forming sealers may require more maintenance.
- **Can DuraCore products extend the life of concrete?** Yes - densifiers, repellers and moisture treatments all support long-term durability.
- **Will these products prevent cracking?** No - cracking is structural and cannot be prevented by surface or penetrating treatments.

### Safety & Environmental

- **Are DuraCore products low VOC?** Yes - DuraCore's penetrating treatments are all low-VOC and suitable for use in enclosed or occupied environments.
- **Are these products safe to use indoors?** Yes - all DuraCore treatments are designed for safe indoor use when applied according to instructions.
- **Do I need special PPE to apply these products?** Only basic protective gear is recommended for most applications.
- **Are DuraCore products safe around pets and plants once dry?** Yes - once cured, surfaces treated with DuraCore products are inert and safe.
