What it is

Politura is Achtis’s own microcement, launched in 2016 and built on decades of microcement experience. It’s made from quartz sand, which at Mohs 7 is a full step harder than the calcite or silica sand (Mohs 3 to 6) most microcements use. That makes it one of the hardest microcements on the market, scratch resistant to a steel file rather than just a coin or fingernail. One contractor who tested it against other microcements called it “the Bugatti Veyron” of microcements.

Politura Medium is the whole system: base and finish in one product. It’s fully powdered with the polymers already in it, so you just add water, and it’s supplied pre-coloured to your chosen shade, so every batch on a job matches. Laid in three coats on floors and two on walls, it builds to a seamless 2–3 mm finish in two to three days.

It’s hard enough to polish without wax, so it looks similar to polished concrete without the upkeep or bacteria build-up that wax finishes bring. It’s rated for underfloor heating and needs no reinforcing mesh.

In bathrooms, use Politura on floors, walls and worktops away from direct water. For showers and wet rooms, choose an ErreLAB resin system instead.

Four finishes from one product

The finish comes from how the trowel and sander work the final coats, not from a second material. Ask for a sample before you decide.

TexturedRipples and movement worked into the coats. The hardest to match, so approve a sample first.

Salt and PepperA flatter, industrial look.

Smooth PolishedThe closest finish to polished concrete, burnished and finished up to 2000 grit.

CloudySubtle marbled movement, similar to Venetian plaster.

Works with Politura Medium

Key features

Mohs 7 quartzOne of the hardest microcements on the market.

Just add waterThe polymers are already in the powder.

Pre-coloured to order27 named colours with no pigment to measure on site, or a neutral base if you’d rather tint it yourself.

FastA 2–3 day system, quicker than most microcements.

Polishes without waxA true concrete look with no wax build-up.

Underfloor heatingRated for use with underfloor heating.

No chatter marksGoes down smoothly with very little effort.

UV stableFor floors, walls, stairs and worktops.

Tested performance

Independently verified in third-party testing.

7 MohsQuartz sand hardnessA full step harder than the calcite or silica sand in most microcements.

46 N/mm²Compressive strengthWith a bending tensile strength of 10 N/mm².

83 Shore DHardnessScratch resistant to a steel file.

R9Slip resistanceAs standard. Anti-slip additives raise it further.

Light foot traffic after 8–10 hours at 20°C, and 18–24 hours after sealing. For more grip, add KA 150 to APU48 or RT 10 to Micro Sol+.

Three ways to seal it

Choose the sealer for what the room needs: true colour, maximum water resistance, or both.

Pre Seal and APU48Water-based and true to the sample colour. For homes, kitchens, bathrooms and commercial floors. Full cure in 28 days.

Micro Sol+Solvent-based and the most water resistant, for commercial and light industrial use. It darkens the colour. Full cure in 7 days.

All three togetherPre Seal, APU48, then Micro Sol+, for true colour with industrial-grade resistance.

Installation

Skilled DIY or professional. Politura is one of our easiest microcement systems and ideal for a first project. It goes down in four stages over two to three days.

How Politura is applied

Check the substrate: rigid, solid, level, dry and keyed, at least 35 N/mm², with new screed cured for 28 days. Remove any resin coating and take off existing wall tiles (see the questions below), then repair cracks and tape joints.
Prime: Politura Primer on concrete, metal or gypsum, EP72 on damp substrates, or EP80 with sand broadcast to rejection on timber.
Mix each 10 kg tub of Politura Medium with 3.2 to 3.8 litres of water and trowel it on, keeping a wet edge. Recoat after 3 to 4 hours, sanding between coats with a 50-grit diamond pad: 3 coats on floors, 2 on walls.
Work and sand the final coat for your chosen finish.
Seal with Pre Seal and APU48, Micro Sol+, or all three. Allow 18 to 24 hours before foot traffic and 28 days before heavy use.

Mrs Microcement answers the questions we’re asked most.

Quick answers

Can Politura go in bathrooms?

Yes, on floors, walls and worktops outside direct water contact. It isn’t recommended for showers or other areas that are constantly wet. For those, ask about our ErreLAB resin systems.

Which sealer should I use?

Pre Seal then APU48 keeps the colour true and suits most domestic jobs. Micro Sol+ is stronger and more industrial but darkens the colour. Use all three together for maximum protection without the darkening.

How long until I can walk on it?

Politura Medium takes 8–10 hours for light foot traffic. Once sealed, allow 18–24 hours before foot traffic.

Does it work with underfloor heating?

Yes. Run new underfloor heating for at least 28 days, then switch it off before starting the system.

What substrates does it go on?

Concrete, metal, timber and gypsum, each with its own primer.

Can it go over existing wall tiles?

We recommend taking them off. Tiles can be covered with the right preparation, but Politura has no tile primer of its own, so going over them needs a different system. Once they’re off, the wall behind is primed like any other standard substrate.

How many colours are there?

27, all named and pre-coloured to order, with no mixing or measuring pigment on site. Contractors can also order a neutral base and tint only what each job needs.

Do I need a reinforcing mesh?

No. Politura has enough flexibility and strength not to need one.

Is it slip resistant?

It’s R9 as standard. Anti-slip additives increase this further: KA 150 for APU48, RT 10 for Micro Sol+.

Can I get a sample?

Yes, small samples or full sample kits. Call or email us to order one.

What’s the lead time?

Everything is kept in stock in the UK. Orders are usually processed in 1–2 days, with next-day UK delivery.

Do you offer training?

Yes. Our Start here course gives hands-on Politura training, whether you’re new to microcement or adding it to your skills.
