Waterproofing products online: when the buyer needs a site assessment, not a cart
A leak or seepage enquiry is a diagnosis question, so route it to a call or site visit with a few triage questions and photos, and keep the cart for small, known repairs on sound surfaces.

"Water is coming through the bedroom ceiling. Which product should I buy?" arrives on the website chat on the first wet evening of the monsoon. Selling a bucket in reply is the quickest route to a one-star review, because the stain is often not directly under the gap. A leak or seepage question is a diagnosis question. Ask four questions and for three photos. Send active leaks, damp rising from the floor and wide cracks to a call or a site visit. Keep the cart for small, known jobs on sound surfaces.
Why the cart is the wrong answer to a leak
Water travels. A failed joint on a terrace can show up as a stain two rooms away. Damp at the bottom of a wall, with white salty marks on the plaster, is coming up from the ground or from a pipe, not down from the rain. A wet patch on a bathroom ceiling may be the floor trap of the flat above.
Each needs a different product. Some need a plumber. The buyer does not know which one applies, and a product page cannot tell them. So a buy button on a leak enquiry does the buyer no favour and does you real damage. The product fails because it was the wrong product for that water, and the review blames the product.
Four questions and three photos before anything is sold
Put these in the website chat, in a WhatsApp quick reply and on a card beside the counter phone. Whoever answers asks them in this order.
- Where do you see the water or damp: the ceiling, the top of a wall, the bottom of a wall, or around a window?
- Is it there only when it rains, or all the time?
- What is directly above it: an open terrace, another flat's bathroom, a water tank, or a sunshade?
- How old is the building, and has this spot been treated before?
Then ask for three photos: the stain from across the room, the stain close up, and whatever is above it.
The answers sort the enquiry into one of three routes.
Cart. A hairline crack on a dry wall, a gap around a pipe or a window frame, a sound terrace the owner wants coated before the rains, a small sunshade. Send the product link with the surface preparation steps from the data sheet.
Call. Water only when it rains, under a terrace the buyer can photograph, with no visible cracks. Someone who knows how to read the photos decides on the call whether it is a coating job or a visit.
Visit. Water all the time, which may point to plumbing. Damp rising from the floor. Wide or growing cracks. A leak below somebody else's flat. Anything treated once already that failed.
Who you are really selling to
In an apartment, the terrace belongs to everyone. The top-floor owner who is getting wet does not decide; the association secretary or the committee does, and nobody goes up with a bucket of coating until they agree. Sell to the top-floor owner and your inspection report becomes the document carried to the committee meeting. Write it so a treasurer can follow it: what was found, where, what you suggest and what it costs.
In an independent house the owner decides, but with a mason or contractor in the room who has a favourite brand. Ask early who will apply it. If it is the owner's mason, send the data sheet to the mason, not just the owner.
What to tell a buyer in the middle of the monsoon
Many coatings ask for a dry surface on their data sheet, and the enquiry arrives in the rain. Check the sheet for each product you sell, and give the buyer a two-part answer. First, what can be done now to limit the damage: clearing the terrace outlets, sealing an obvious gap, a sheet over the worst spot. Second, the proper treatment once the surface has dried.
Book the inspection now and the work for the first dry stretch. The dealer who says "wait, and here is why" keeps the customer. The one who sells a coating for a wet terrace gets the complaint.
For example: a Mangaluru dealer and the bathroom upstairs
Take an invented case: a waterproofing dealer in Mangaluru whose website sells terrace coatings by the bucket, with a buy button and no questions. A buyer in a second-floor flat orders a terrace coating for a stain on the bathroom ceiling, sure the rain is getting in. The building's mason coats the terrace on the roof. The stain stays, because the water was coming from the floor trap of the bathroom directly above, in the third-floor flat. The review calls the product useless.
Nothing was wrong with the coating. The mistake was selling it before anyone asked what sat above the stain. The dealer now runs the four questions in the chat before any terrace coating is sold, adds a line on every coating page saying "Not sure where the water is coming from? Send us three photos first", and books paid inspections through two applicators it trusts. Chat replies got slower, and some buyers who only wanted a bucket went elsewhere.
When not to offer a visit
An inspection is only worth offering if someone can do it well. If you have no applicator you trust, and nobody at the counter can read a photo of a damp wall, do not promise a visit you cannot staff. Sell the cart jobs, and pass leak enquiries to a named applicator with the buyer's photos attached.
Skip the questions, too, for buyers who have already diagnosed the job. Contractors and applicators want a trade price list and the cart. So does an owner recoating the same terrace with the product that held last time.
Before the next rains
Print the four questions. Tape them beside the phone that takes leak calls. Whoever answers asks them before naming a product, and writes the answers down. Sorting enquiries this way is lead qualification work, and waterproofing dealers sit in our e-commerce sales and marketing group.
