The ceiling is leaking tonight, and the buyer wants to know which product stops it.
Nobody shops for waterproofing for fun. The buyer has a damp patch that spreads each monsoon, a terrace that floods the flat below, or a bathroom that stains the neighbour's ceiling. They search in the middle of the problem and take the first clear answer.
A 90-minute audit call and a written, scored report. Turnaround, reporting and term are agreed in writing after the audit.
In one paragraph
Waterproofing products are the coatings, membranes, additives and sealants used to stop water from entering terraces, bathrooms, basements, tanks and walls. GullySales builds pages around the leak a buyer is trying to fix, a quotation route for applicators and contractors, and a follow-up that carries the enquiry through the site visit.
A product page cannot solve a leak, because the right system depends on where the water enters. So the sale often needs a site visit or a photograph, and the sellers who win are the ones who ask for it early.

Who it is for
This is written for you if you sell waterproofing products online.
- Manufacturers and dealers of terrace, bathroom, basement and tank waterproofing systems
- Suppliers of sealants, crack fillers, crystalline additives and membranes
- Applicator contractors who sell the material together with the labour
- Dealers who serve builders and housing societies with repair work
Not for
It is not the right fit if.
- A seller who cannot visit or review photographs of the site. Waterproofing sold blind comes back as a complaint.
- Sellers whose products are only for new-build projects specified by an architect. The buyer is not searching online.
How buyers choose
What decides the sale of waterproofing products.
Where the water gets in
The search says leaking terrace, seepage in the wall, wet bathroom floor, sump tank leakage. Each place has a different system, so each deserves a different page rather than a single list of products.
Product or applied job
A homeowner wants the leak fixed and rarely wants to apply the coating. The buyer is deciding whether to buy a pack and hire a painter, or pay a specialist to do the whole job.
A photograph of the damage
A buyer who sends a photograph of the stain and the terrace is more serious than one who asks only for a price. Asking for it filters out browsing.
Trust after a failed job
Many buyers have already tried a coating that failed. They ask what is different, how the surface will be prepared and who is responsible if it leaks again.
Where sales are lost
What usually goes wrong when you sell waterproofing products online.
In the words sellers use on the first call.
“Enquiries want a price for a leak we have not seen”
Quoting from a phone call guesses the area and the cause. A short form with photographs, floor and the place of the leak makes a first estimate possible, and a visit confirms it.
“People buy the product and apply it badly”
Waterproofing fails more from surface preparation than from the product. Application guidance has to be part of the page, and your trained applicators should be offered to the buyer who is unsure.
“Buyers do not trust any waterproofing claim”
After a bad experience, they discount promises. Show where the product was applied, what the surface was and what the owner says now, with permission.
“The leak season brings a flood of calls we cannot answer”
Everyone phones in the same fortnight, and the late ones are lost. A form that sorts by urgency and area, and a reply on WhatsApp the same day, hold them until you can visit.
The scope
The work we would propose for waterproofing products.
Measured on purchases and, for trade buyers, qualified enquiries, quotation requests and repeat orders. Anything here that needs a platform or tool we have not used with you is confirmed in the audit before it goes in the scope.
- Pages by leak locationSeparate pages for terrace, bathroom, basement, tank and wall seepage, each with the preparation, the system and the questions a buyer asks, written for the way people describe a leak.
- Site-photo enquiry formA request form that takes a photograph, the floor, the area and the place of the leak, and routes it to the applicator or sales person who covers that pincode.
- Applicator network enquiriesA page and a process for contractors who want to apply your system, with a way to check who is active and who is being sent leads.
- Quotation and site-visit follow-upEvery enquiry has a visit date or a reason for none, and every quotation gets a call before the next rain.
- Completed-job proofPhotographs of finished terraces and bathrooms with the year and the owner's permission, and a note on what was done on the surface first.
Rain-season readiness
Stock, applicators and reply rules are made ready before the first heavy rains, and ads begin only once your team can answer them.
What we do
What you get for waterproofing products.
Each deliverable and what it is there to change.
A leak diagnosis guide
Questions that identify where water is entering, with the matching system for each. It sends the buyer to the right product, not the cheapest.
A site photo enquiry page
A form that asks for pictures, area and location. It makes the first quotation closer to the final one.
A surface preparation sheet
What to remove, clean, repair and prime before applying each system. It reduces failures that are blamed on you.
An applicator directory by pincode
Who covers which area, for buyers who want the job done. It turns product enquiries into labour and material orders.
How the result is measured
- Qualified enquiries with a site photograph
- Quotation requests
- Site visits completed
- Follow-up on each quotation
- Orders won
- Repeat and referral jobs
Recorded as a baseline before work starts, so every later report has an honest comparison.
How it works
From your first message to the first report.
No open-ended retainer. Every step gives you something in writing.
First
Free audit call
90 minutes with whoever handles your enquiries: how they arrive, how fast they are answered, where they are lost.
After the call
Written, scored report
Six areas scored, fixes ranked by return and cost. If you want our help, the scope, the fee and the reporting come with it, in writing.
Before work starts
Baseline recorded
Enquiries by source, reply time, conversion and cost per order, written down so every later report has an honest comparison.
After the baseline
The first fix goes live
Usually the cheapest one on the report: reply time, a follow-up sequence or the marketing-to-sales handover.
As agreed
Report against the baseline
What moved, what did not, and what changes next, in plain words. How often you get it is set in writing before work starts.
At renewal
Renew on the numbers
The term ends and you decide whether to continue from the results. The length is agreed in writing before anything starts.
What we need from you
What to have ready before the audit call.
None of it has to be tidy. We read what you have.
- Your system list, data sheets and application method for each
- Photographs of completed jobs, with address area and year
- The list of applicators you work with and the areas they cover
- Your last twenty enquiries and what happened to each
- Complaints about leaks after application and their causes
Selling in India and abroad
Selling waterproofing products beyond your own market.
Where you sell decides sizes, units, seasons and returns. We work from Bengaluru and have no overseas office, so for a new country we start from your own sales and the platforms you already use.
Climate and building types differ
A terrace in a monsoon city and a basement in a cold country face different water. State the conditions your system was developed for.
Service is the difficulty
Overseas buyers ask who will apply it and who stands behind it. Without an applicator there, sell the product to local contractors, and let your forwarder confirm the import terms.
