Cemher Clay One Rustic

|

Rated 4.5/5 by hundreds of happy customers

£95.00 (incl. VAT)
  • Size: 10kg

Clay One Rustic® is a ready to use clay-based, waterproof mortar.  It benefits from both the organic aesthetic of earthy materials and the superior technical performance of a Cemher microcement. Incredibly natural, stony patina for a time-weathered look. This exciting new product can be used on almost all surfaces including bathrooms & outdoors.

  • Clay-based microcement, natural, stony patina
  • 100% Waterproof, ideal for bathrooms & wet rooms
  • Tactile rustic effect, one colour only

Uses / Areas of Application

Unlike other mineral coatings, Clay One Rustic® comes ready to use, eliminating mixing errors and reducing application time. Its consistency and body allow it to be worked with different tools to achieve more organic or mineral effects, depending on the pressure and movement of the applicator.
Fully waterproof and requiring no catalysts, Clay One Rustic ® stands out as a new-generation technical and aesthetic solution, designed for projects seeking natural visual character, structural solidity, and timeless finishes.

The formula of the Clay One Rustic® microcement line, is characterised by being incredibly versatile, as it consists of two possible products in one.

Clay One Rustic® can be applied in a single-component, as ‘ready-to-use’ microcement with a hardness of 27 MPa. Choose Clay One Rustic Plus ‘dual component’ microcement with the addition of Microne Plus Comp B (Catalyst), which increases its hardness to 50 MPa.

Clay One Rustic® ‘ready to use’ has an incredible elasticity, which makes it forgiving on small movements in the substrate.

Unlike may microcements on the market, Clay One Rustic is completely waterproof, even before sealers. This is essential for wet environments like showers, wet rooms and bathrooms. Where it does the jobs of a tanking product and a decorative surface finish in one.

Thanks to its high impermeability it is not necessary to apply pre-sealers, two coats of AquaMax is enough to avoid dust and stains. Which, due to the low absorption rate of Clay One Rustic, is extremely easy to apply.

Clay One Rustic facilitates one of the quickest microcement installation times known at 3 – 4 days.

Clay One Rustic is the ideal choice for:

• Tanking and decorating shower enclosures, shower trays, wet rooms and bathrooms
• Highly decorative continuous coatings for interior floors, walls and ceilings
• Coating of interior and exterior furniture, shelves, kitchen countertops, counters
• Not suitable for swimming pools or continuously immersed surfaces
• Covering of old ceramic tile surfaces

Characteristics / Benefits

• Clay-based microcement, natural, stony patina
• 100% waterproof microcement
• Pre-mixed for easy installation, excellent workability
• Can be applied on almost any type of surface: plaster, plasterboard, cement board, Aqua4ma panels, concrete, self-leveller, composite timber boards, tiles, metals
• Non-yellowing
• Applicable in interiors and exteriors
• Must be applied thinly, no thicker than the grain

Clay One Rustic® is pre-mixed, and only comes in one colour. All you need to do is give it a good mix to loosen it.

To do this, mix thoroughly with a microcement mixer head attachment on a cordless drill.  If it still feels stiff, you can add up to 10% water to loosen & mix further.  That’s a maximum of 1l per 10kg.

Let the mixture rest for a few minutes before applying.

It’s important that you go as thin as the grain with Clay One Rustic.

Using a Microcement Trowel, work your way out from one corner creating a random edge pattern. Keep trowel movements small and random, avoid long sweeping arches – as these will show through to your final finish.

Use the grain in the microcement as your level – if you apply the microcement thicker than the size of the grain, the finish won’t be as strong and will require a lot more sanding. Run the trowel back over each section that you have put down to smooth it out and remove excess product.

Completely cover each surface without stopping. For complete rooms, start with ceilings, then walls from left to right (or right to left) and then the floor.

Run your finger or a corner trowel along internal corners to push the microcement into the corner and then gently trowel away the excess product.

Once dry, apply a thin coat of Microne Fine Neutral over the Clay One Rustic.

I’ve been using relentless microcement for quite a few years now, great product range. They have pretty much everything you need for your projects whether it be inside, outside, worktops, bathrooms, and flooring. Richie and sally are easy to talk to and they know everything you need to know about their products. 5 stars everytime

We’re over the moon

Amazing product and service as always from Relentless. Just finished my living room floor and walls and we’re over the moon with the finish. Thanks Relentless 👍

There’s a product for every need!

I’ve done quite a few jobs now over the past four years and can’t fault it. There’s a product for every need! It’s easy to apply once you get the hang of it and anything that you’re not sure about relentless are there to advise you. The only problem you’ll have is deciding which colour to choose !

Products are great

Products are great and we have purchased them several times, but the highlight is costumer servise. It’s rare to have prompt and professional costumer service – this is the main reason why we are choosing this company. We had issues once with the delivery and Sally handled it in the best way possible. Overall delivery is actually super quick.
