The ARDEX Natural Stone Range

Eliminating the Risks of Water Staining, Curling and Warping in Natural Stone Installations

Natural and agglomerated stones such as granite, marble and limestone are naturally durable materials that can last a lifetime. However, like any product, problems may occur if they are not installed properly.

The main issue associated with natural stone is determining whether the stone is moisture sensitive or not and, following that, using the correct products to fix it. In most instances natural stone tiles will not have a sensitivity to moisture, and non-specialist products can be used with confidence; however, using such products to fix moisture sensitive stone can lead to permanent defects in the finished result.

Typically occurring during the bedding and grouting process, moisture from traditional adhesives and grouts can migrate into the stone and cause discolouration, staining and even warping.

For tile fixers using moisture sensitive natural stone or agglomerated stone, or for those who are unsure, ARDEX has developed a system of products specifically designed to eliminate these problems, helping to ensure a risk free installation every time.

ARDEX natural stone products incorporate our unique ‘RAPIDRY FORMULA’ technology and ‘lock’ the mix water within the mortar, virtually eliminating the risk of water staining, curling and warping.

Council House Refurbishment

In 2014 Wrexham council started a refurbishment program for all their council houses built in the 1960s. The existing subfloors were a mixture of quarry tiles or concrete, and following moisture testing, the R.H (Relative Humidity) readings were over 85%, which was probably the result of an absent or ineffective damp proof membrane.

ARDEX UK is a system solution provider of high-performance speciality building materials, and the brand choice for installers and distributors throughout the construction industry.

ARDEX products used on the project:

  • ARDITEX NA – Ultra Rapid Setting Subfloor Latex Levelling and Smoothing Compound
  • ARDEX DPM 1 C – One Coat Surface Damp Proof Membrane

Around 5,000 properties will be refurbished each year, with another three years to go on the project. ARDEX are working in partnership with Tarkett, using Safetred Spectrum Vinyl Flooring.

For The Perfect Floor You Need the perfect subfloor

Established in 2009, House to Home Furnishers, based in Stranraer, Wigtownshire, is a family run business offering a complete home furnishing service. Since opening, they have continually strived to bring their customers the best in quality home furnishings and fitting services, from new flooring installations, furniture and more, along with a customer service which is second to none.

House to Home Furnishers regularly install Luxury Vinyl Tile floorcoverings using ARDEX products, and Jamie Nelson, owner, commented “We have a great relationship with our local ARDEX Area Sales Manager, Morris Pate, who introduced us to ARDEX K 39 last year. Since then we always carry it in stock as one of our preferred levelling compounds.”

“ARDEX K 39 has amazing flow; it’s super smooth! Other levelling compounds leave joint marks and ridges, which usually means additional prep work and rubbing down the next day. ARDEX K 39 guarantees a perfect subfloor, and gives me peace of mind that, when I come back the next day, I’m ready to fit the floorcovering with no delays.”

In this particular installation, Jamie used the following ARDEX products:

  • ARDEX MVS 95 – One Component Residual Moisture Vapour Suppressant
  • ARDEX K 39 – Extended Workability, High Flow Levelling and Smoothing Compound
  • The hall and front porch were fitted with Neobo, Amber Glaze Parquet. The kitchen and dining area were fitted with Karndean Art Select Melbourne.

Tottenham Court Road Underground Station Refurbishment

Tottenham Court Road Underground Station opened as part of the Central London Railway (CLR) on 30th July 1900. Today, its location in the capital means it connects over 150,000 passengers daily; a figure that is expected to increase to over 200,000 when Cross Rail serves the station in 2018.

Throughout 2015 DMC Contracts Ltd, a main contractor for refurbishment works on London Underground, working alongside Taylor Woodrow BAM Nuttall (TWBN), used ARDEX products to complete the Central Line’s Tottenham Court Road Station upgrade.

Dave McCartney, Chief Executive of DMC Contracts Ltd commented “We have a long standing relationship with ARDEX UK, having worked for many years with their team, developing designs and completing a number of major projects across the UK to the satisfaction of our clients”

The design required DMC Contracts Ltd to complete a full wall and floor tiling installation that included the bespoke production of pre-cast skirtings and treads for the stairs and walkways, and breaking back to the existing substrate, making repairs using ARDEX Fast Track Repair Mortars and Screed Cements.

London Underground Ltd recommend the use of EXPAMET 267 Stainless Steel Rib Lath. The metal sheets provide a solid, secure background, and are ideal for use in the refurbishment of damaged, old and deteriorated walls; commonly found in the underground environment. ARDEX AM 100 Tile Render was applied to the Rib Lath, which were profiled to suit the natural curve of the walls. ARDEX AM 100 provided a smooth surface, which was ready for tiling in the shortest possible time, just two hours after application, meaning the area could be opened up to public access without additional hoarding.

ARDEX MICROTEC® X 78 was specified to fix the floor tiles because of its extremely high bond strength. Additionally, the semi-pourable consistency of the product helped the tile fixers quickly and easily achieve solid bed fixing, speeding up the installation process.

Due to the demanding environment of the underground, ARDEX MICROTEC® X 77 was specified on the walls. The adhesive is resistant to moisture ingress and has a high bond strength, meaning it can cope with both the vibrations from passing trains, and heavy trafficking of the passages and platforms.

The following products were specified for use in this project:

  • ARDEX A 38 – Ultra Rapid Drying Cement for Internal & External Screeds
  • ARDEX AM 100 – Rapid Hardening Tile Render
  • ARDEX A 46 – Multi-Purpose Repair Mortar
  • ARDEX MICROTEC® X 78 – Flexible Semi-Pourable Floor Tile Adhesive
  • ARDEX MICROTEC® X 77 – Flexible Wall & Floor Tile Adhesive
  • ARDEX FLEX FL – Rapid Setting Flexible Tile Grout

Paul Forrester, ARDEX Business Development Manager, commented “Since its opening the station has seen many modifications over the years, and this project has been the biggest yet. The main benefits ARDEX offered DMC Contracts Ltd were, not only the rapid drying times and strength of the finished products, but the technical and onsite support at every stage of the project.”

ARDITEX NA – Ultra Rapid Setting Latex Subfloor Levelling and Smoothing Compound reduces the need for intensive preparation and priming, and was used directly over the existing subfloor, which was contaminated with old adhesive residues. In addition, the ultra rapid setting properties of ARDITEX NA meant that the final floorcovering could be applied after just 4 hours.
