Floor questions, straight answers.

A cementitious, polymer-modified, fibre-reinforced overlay. Mixed and poured in situ, then floated to a polished concrete finish. You get the look of a poured concrete slab without pouring one.

It goes over the floor you already have, at 4mm minimum, 12mm maximum, 6mm optimum. That’s the whole trick: enough depth to behave like concrete, thin enough to sit on almost anything.

No. PSR is cement-based, not a resin or epoxy coating, so it wears, ages and patinas like concrete rather than sitting on top of the floor as a film.

Puur Microcrete is a separate system for walls and other vertical surfaces, when you want the same look running up a wall. Different product, same family.

Usually, yes: screed, sound tiles, ply, cement boards and raised access flooring all work with the right preparation.

What PSR won’t do is rescue a failing floor. It’s a finish, not a structural repair. If the slab underneath moves or cracks, that will show through. We’d rather check that before the pour than after.

Yes. At Headley Barn Conversion we laid 130m² of PSR in RAL 7023 over screed with underfloor heating.

Before you commit, tell us the heating system, the floor build-up and the site conditions. A thin overlay alone can’t tell you your heat output, warm-up time or running cost — those depend on the heating design, insulation and the whole construction.

Based in London, laying floors nationwide for over 25 years. Commercial and residential, from a barn conversion to a 366m² showroom with 20 stair treads.

Natural (white), or pigmented to any RAL classic or NCS colour. Around fifty greys if you’d rather not commit to a decision that big.

Colour is agreed from a physical sample, not a screen.

We hold our ten standard colours as made-up samples in stock, so those can go out straight away.

Want a particular RAL or NCS colour? We’ll make up a physical sample of that for a small charge, which is credited back against a confirmed order.

No. Cement is a variable material, so the sample gives you the direction of the colour and the floor will have its own tone, shade variation and patina. Anyone who tells you otherwise hasn’t worked with cement much.

Approve a physical sample, and judge it in the room in the light the room actually gets. That’s the check that matters.

Try the Puur Visualiser: upload a photo of the room and see PSR or Mono in it, in standard colours or any RAL or NCS colour. Handy for settling a direction early on. It’s an illustration, not a colour standard.

Stairs, yes — at the Milliken showroom we formed 20 treads in tread trays, in the same white PSR as the floor. Walls and other vertical surfaces are Microcrete, a separate system built for them.

Want the finish somewhere unusual? Send a photo and we’ll tell you honestly whether it’s the right system for that job.

Between 4mm and 12mm, with 6mm the optimum for most floors. Thin enough that doors and thresholds mostly stay where they are, thick enough to grind, polish and live with.

Stability, moisture, contamination, existing coatings and repairs, all checked before anything is mixed. Movement joints and transitions agreed before the pour, not discovered during it.

An overlay covers the surface. It doesn’t take on the job of fixing defects underneath, so agree the preparation and any excluded repairs up front — otherwise the cheapest quote may be answering a different question.

It depends on the area, how much prep the substrate needs and the site conditions. We can mix and pour up to 1,000m² seamlessly in one go, but prep, repairs, curing, sealing and protection all take time too.

Tell us your opening or handover date and we’ll tell you whether it’s realistic before you write it into a programme.

That depends on the system, the sealer and conditions on site, so it’s better agreed in the programme than guessed at. We’ll set out curing, sealing and protection dates at the start, and give you cleaning and maintenance instructions for the sealer we actually used.

The technical sheet is honest about this: hairline surface cracks are possible while the material cures. Substrate movement and structural cracks are a separate matter and still need putting right underneath.

No one can guarantee a cementitious floor stays crack-free. That’s not us hedging, it’s how the material behaves — and it’s why we’d rather talk through joints and the substrate before the spec is written.

Our regular finish measures R12 dry / R11 wet, with satin or anti-slip surfaces to suit the area. If it’s an entrance, a wet room or a ramp, tell us before you specify so the finish matches the risk.

For typical retail and office use, yes — that’s most of what we lay. Rolling loads, heavy point loads and industrial traffic are a different conversation, and depend on the build-up and the substrate under it.

Send us the actual use for the space and we’ll say whether PSR is the right answer, or whether something else would serve you better.

With instructions for the sealer actually used on your floor, rather than a generic sheet. We give those at handover, and there’s a full care guide in the Journal.

Yes. It’s a cementitious finish with natural variation, so it picks up a patina with use and cleaning. For most people that’s the point — a floor that looks lived in rather than newly installed for the next twenty years.

Depends on the sealer and how hard the floor works. Ask for a maintenance schedule at handover and you’ll know what to expect and when, rather than finding out from a dull patch.

Sometimes. A patch in a cementitious, patinated floor can show, so the honest answer is: send us a photo before you try anything. We’d rather look at it and tell you what’s achievable.

Depends on the area, the substrate and how much prep it needs, so a price per square metre without seeing the floor is guesswork dressed up as a quote.

Send drawings, photographs and the area through the contact form, and make sure preparation and any excluded repairs are spelled out, so you’re comparing quotes for the same work.

It varies with what’s involved and where it is, so ask us. A small, tricky floor can be worth doing properly; a large one with the wrong substrate may not be.

Yes. Samples, technical data sheet, full specification, and a conversation about substrates, movement joints or programme before any of it goes into a written spec. Cheaper at that stage than on site.

Send drawings, photographs and the floor area through the contact form — you can attach up to five files — or ring us. If you’re unsure whether PSR suits your floor, that’s a perfectly good first message.
