You don't
measure it.
You guess.
Every brickie does. ProDoses puts the exact dose in every mix — so you stop weakening your mortar without even knowing it.
“I've laid slabs for 25 years and I still guessed the dose every time. So I fixed it.”
The guess vs the dose
What guessing costs you
You know how to lay. But nobody measures plasticiser — and the dose you can't see is the one that bites you later.
Over-dose
Too much air entrained. Weaker mortar that looks fine today and crumbles in five winters. That's a callback you didn't budget for.
Under-dose
Mix won't work. So you add water to loosen it — and you've just dropped the strength of every joint on the job.
Different every mix
Batch to batch, your dose drifts. Inconsistent colour, inconsistent strength, inconsistent finish. The dose nobody checks.
One bottle. One mix. Done.

Built by a tradesman, not a chemist
“25 years on the tools. Still guessing the dose. So I made the thing I wished existed.”
ProDoses isn't a chemical brand trying to sell to trades. It's a product made by someone who's mixed mortar on real jobs for a quarter of a century — and got tired of pouring plasticiser by eye and hoping.
Same concentrated chemistry the pros already trust. Pre-measured into one bottle per mix. No measuring jug, no waste, no weak mortar. Just tip it in and get on with the job.
Why ProDoses
Perfect dose
The right amount in every single mix. No eyeballing, no guessing, no weak joints.
Concentrated
One small bottle replaces a glug from the tub. Same strength, none of the waste.
Less plastic
Recyclable bottle, concentrated formula. Less material per mix than the bulk tub.
Trade-made
Designed on real jobs by a 25-year tradesman. Made for the mixer, not the lab.
