Selling adhesives and grouts online

Adhesives and grouts have the best repeat-purchase profile in building materials and some of the worst freight economics. They are consumed and reordered, which is what you want, and they weigh a great deal relative to their value, which is what you do not. The businesses that succeed here mostly stop thinking about a shop and start thinking about a selector.

Because the difficult part is not taking the order. It is that the customer does not know which product they need or how much of it.

Why is this category chosen differently?

Nobody wants adhesive. They want a tile to stay on a wall.

The right product depends on what is being fixed, to what substrate, in what conditions — interior or exterior, submerged or dry, over existing tile or onto fresh plaster, large format or small. Get it wrong and the installation fails months later, which is why the decision usually sits with a contractor rather than the person paying.

A product list does not help someone make that decision. It presents twelve options that look similar and asks them to choose, which is exactly the moment they close the tab and phone a dealer.

A selector that asks four questions and returns one product with its data sheet converts far better than a category page. It is also the thing your competitors’ websites do not have.

Why does quantity stop the sale?

Because coverage is a calculation, not a lookup.

Adhesive consumption depends on tile size, substrate flatness and trowel notch — the same bag covers materially different areas at a 6mm notch and a 10mm one. Grout follows a formula across tile size, joint width and joint depth. A customer with a room measurement cannot convert that into bags without help.

So the sequence that works is: help them establish the area, apply your real coverage data, return a quantity in bags, then offer to sell it. Ask them to choose a quantity first and most of them leave.

This is the same mechanic behind Tile Calc, which calculates adhesive and grout alongside the tiles rather than leaving them as a second trip.

What about the freight problem?

It is real and it does not go away, so it has to be designed around.

Approach	Works when	Watch for
Local fulfilment through dealers	Almost always — the default answer	Needs dealer stock and response
Small-pack range only	Repair and small jobs	Not the professional market
Minimum order value	Contractor buyers	Excludes homeowners entirely
Bundle with light items	Tools, spacers, cleaners	Improves value density per order
Regional shipping only	Near your depot	Limits reach, protects margin

The first row is where most of this trade ends up, and we have written about it in detail in selling heavy goods without shipping them.

The fourth is underused. An order of adhesive alone has poor value density; the same order with a trowel, spacers, a sponge and a cleaner is a better basket and a more useful delivery for the customer — they were going to buy those anyway.

What about shelf life?

A real constraint that most online stores ignore until a complaint arrives.

Cement-based products have a finite shelf life, and a bag stored badly or held too long performs differently. Selling online means stock may sit in a warehouse or at a dealer for longer than it would at a busy counter, and the customer has no way of knowing.

Two things worth building. Batch and date awareness in stock, so older stock moves first rather than sitting at the back. And a stated position on what you supply — a business that says it dispatches within a defined period of manufacture is making a claim competitors are not, and it is checkable.

Who is actually buying?

Two audiences who want opposite things from the same page.

Homeowners and small jobs. Buying once, uncertain, need the selector and the quantity calculation. Price sensitive but low volume. They convert on guidance.

Contractors and applicators. Know exactly what they want, buy the same thing repeatedly, and value speed above everything. They convert on a reorder button and abandon anything that makes them navigate.

Serve both by making the selector prominent for new visitors and reordering trivial for returning ones. A contractor who has bought before should be two taps from the same order.

The contractor relationship is the more valuable one, and it extends beyond the store — applicator loyalty schemes, technical training and data sheets are part of the same system rather than marketing extras.

What should you build first?

The selector and the coverage calculator, before the store.

Both are useful without a checkout. They capture enquiries, they answer questions people are actively searching for, and they can route the resulting order to a dealer. If you never build the shop, you have still built the thing customers needed.

Keep coverage data as configuration owned by your technical team rather than hard-coded. Formulations change, and a calculator quoting figures from a superseded brochure is worse than none — it produces confident wrong answers, and the installation failure arrives months later.

Common questions

Should we publish coverage figures publicly?

Yes. They are on your bags and in your data sheets already, and being the site that answers “how much does a bag cover” earns the search traffic. State the conditions alongside the figure — a coverage number without a trowel size is not useful.

Will contractors buy online, or do they stay with their dealer?

For known repeat items, increasingly online. For anything needing credit, they stay with the dealer. Local fulfilment is what lets you have both — the order is placed with you and supplied by the dealer they already use.

How do we handle wrong-product returns?

Opened bags cannot be resold, so the policy has to be clear before purchase. This is another argument for the selector — a customer guided to the right product returns fewer of them, which is a margin benefit rather than a service one.

Is a subscription or repeat-order model worth trying?

For contractors with steady consumption, a saved order they can repeat in two taps captures most of the benefit without the complexity of a subscription. Genuine subscriptions rarely suit a trade where volume follows the jobs won.
