Frequently asked questions

Practical answers on product selection, application, ordering, and delivery — without the sales fluff.

Products & Selection

What types of waterproofing products do you supply?

We supply a comprehensive range of waterproofing solutions including cementitious coatings (rigid and flexible), crystalline waterproofing, polyurethane liquid-applied membranes, bituminous coatings, and elastomeric coatings. Each system is suited for different applications — from basement walls and water tanks to roof terraces and external facades.

Which tile adhesive should I use for large-format vitrified tiles?

For large-format vitrified tiles (above 60×60 cm), we recommend using a C2 or C2TE class polymer-modified tile adhesive with a non-sag formulation. This provides superior bond strength and prevents tile slippage during installation. Our technical team can recommend the best product based on your specific tile size and substrate.

What is the difference between epoxy grout and cement-based grout?

Cement-based grouts are economical and easy to apply, suitable for most residential tiling projects. Epoxy grouts offer far superior chemical resistance, stain resistance, and durability — making them ideal for commercial kitchens, laboratories, food processing areas, and swimming pools. Epoxy grouts are also non-porous, preventing bacterial growth.

Do you provide Technical Data Sheets (TDS) for your products?

Yes, Technical Data Sheets and Safety Data Sheets (SDS) are available for all our products. You can request them by contacting our technical team via the quote form or by emailing us directly. We also provide product selection guidance and application method statements on request.

Are your construction chemicals IS code compliant?

Yes, our products are formulated to meet or exceed relevant Indian Standards (IS codes) as well as international standards including ASTM, EN, and BS specifications. Specific compliance certifications are available in the product documentation upon request.

Application & Technical

How do I apply waterproofing on a roof terrace?

For a roof terrace, the typical process is: (1) Clean and prepare the substrate — remove all dust, oil, and loose material; (2) Repair cracks and fill honeycombed areas with repair mortar; (3) Apply a coat of waterproofing primer; (4) Apply 2–3 coats of liquid-applied waterproofing membrane at a minimum 1.5–2 mm dry film thickness; (5) Protect with a screed or protective layer. Our technical team provides free site-specific method statements.

Can waterproofing be applied on wet or damp surfaces?

Most waterproofing products require a dry or just-damp surface for best adhesion. However, crystalline waterproofing systems and certain polyurethane injection grouts are specifically designed for application on damp and actively leaking surfaces. Contact us to identify the right product for your site conditions.

What is the curing time for tile adhesives before grouting?

Standard cement-based tile adhesives require a curing time of 24 hours before grouting. Fast-setting adhesives may allow grouting in as little as 3–6 hours. Epoxy adhesives typically require 24 hours. Temperature and humidity significantly affect curing times — in cold or humid conditions, allow additional time.

How long does waterproofing last?

The lifespan of a waterproofing system depends on the product type and application quality. Cementitious waterproofing typically lasts 5–10 years. Polyurethane membranes last 10–15 years. Crystalline systems can last the lifetime of the structure as they self-heal minor cracks. Proper surface preparation and application are the most critical factors for durability.

Do you provide on-site technical support?

Yes, our technical representatives can visit your site to provide application guidance, conduct site assessments, and supervise critical applications. For large projects, we offer a complete technical service package including pre-construction consultation, method statement preparation, and quality control inspections.

Ordering & Delivery

What is the minimum order quantity?

There is no minimum order quantity for most products. We supply to individual contractors, construction companies, and homeowners. For bulk orders or project-specific requirements, we offer competitive pricing — please submit a quote request with your estimated quantities.

Do you deliver pan-India?

Yes, we deliver our products across India. Delivery timelines vary by location — typically 2–5 business days for metro cities and 5–10 business days for other areas. For remote locations, additional lead time may apply. Contact us for a delivery timeline specific to your location.

How do I get a quotation for a project?

You can request a quotation by filling out the Get Quote form on our website, or by contacting us directly via email or phone. Please provide details about your project, the type of application, approximate quantities, and your location. We typically respond within 24 business hours.

Do you offer credit terms for contractors and builders?

We offer credit terms for established contractors and construction companies with a documented track record. Credit terms are assessed on a case-by-case basis. Please contact our sales team to discuss credit facilities for your business.

Company & Support

Can you help with product selection for a specific project?

Absolutely. Our technical team specialises in product selection and system design for construction chemical applications. Share your project details — substrate type, area of application, exposure conditions, and performance requirements — and we will recommend the most suitable products and application methodology.

Do you offer training for applicators?

Yes, we conduct training programs for contractors and applicators covering correct surface preparation, product mixing, application techniques, and quality control. Training can be arranged at your site or at our facility. Contact us to schedule a training session.

What are your business hours?

Our office and technical support team is available Monday to Saturday, 9:00 AM to 7:00 PM IST. For urgent site-related technical queries, WhatsApp support is available extended hours.
