A Fast Secure Way to Waterproof a Wet Room

Kerakoll’s Laminate No Crack Waterproofing system allows wet room floors to be waterproofed fast and effectively even when the screed is cracked or has residual moisture.  It is safe for foot traffic immediately allowing other trades to finish off without having to wait for the floor to dry. 

Apply a layer of Biogel No Limits or Revolution on to Keracem Eco or any suitable screed and lay the Green-Pro membrane on top to fix the membrane to the screed.  Next,cover the joins, edges and corners of the Green-Pro membrane with Aquastop 120 waterproofing tape over a layer of Aquastop Fix to ensure water-tightness.  Aquastop Fix is a waterproofing product which uses nano-technology to make it totally water-repellent and give it high chemical stability.  

There is no waiting time before laying coverings on top of Aquastop Fix, so you can fix the tiles immediately using Biogel No Limits or Revolution to create a secure adhesive bond between the tiles and membrane.

Then waterproof the wet room walls with Nanodefense Eco, a single component waterproofing product that has very low levels of VOCs.  It is applied with a roller directly on to the levelled walls and any joints are taped with Aquastop 120 before fixing tiles with Biogel No Limits or Revolution.  Use Fugabella Color grout to grout the joints and Silicone Color to fill the movement joints for both walls and floors.

The Green-Pro Membrane

The Green-Pro membrane is composed of 3 layers – the first has hydrophobic PA fibres which ensure a secure bond with the tile adhesive as well as restricting water movement in the adhesive, the second is an HDPE waterproof structure which bends with the movement in the floor and compensates for stresses caused by hyrgrometric shrinkage and cracks, the third is a non-woven breathable fabric which allows vapour to disperse.  Together these create an uncoupling mat that allows safe installation of tiles and stone over cracked and uncured screeds where waterproofing is required.

Technical Advice and Problem Solving

Every project is unique and it is important to take into account any particular issues that may be present.  The best way to do this is to get the Kerakoll’s technical team involved when choosing the products and to get in touch with them for advice should an unforeseen issue occur on site.

How to lay thin porcelain tiles the Kerakoll way

It is very important to adhere to the British Standard when fixing large size thin porcelain tiles and panels as they are fragile and easy to damage during handling and they can crack if they are not laid correctly leading to failure of the installation.  Handle the tiles using suitable lifting equipment taking special care with corners and edges.

For floors, the substrate should be totally level and stable.  Laying on top of an existing sound tile installation is ideal, otherwise the use of a self-levelling compound such as Keratech Eco R10 which hardens rapidly is recommended.  Adequate time should be left to ensure that all substrates are properly cured to avoid movement after tile installation.

Care should be taken when fixing to ensure that there are no air cavities under the tiles and that the back of the tile is entirely covered by adhesive.  The Standard recommends the use of both back buttering the tile and a layer of adhesive spread across the floor, spreading only enough adhesive for one tile at a time to avoid a skin forming on the adhesive which could prevent proper adhesion.  Biogel adhesives are perfect for this sort of installation, as they thoroughly wet the back of the tile, do not shrink and hold their shape meaning that the tile is fully supported.  Biogel No Limits has an open time of up to 60 mins at 23°C making ‘skinning’ before the tile is laid extremely unlikely.

Grout joints should be at least 5mm for 3m long tiles to allow adequate room for potential movement and avoid damaging fragile edges and corners.  Movement joints should also be built in to allow for shrinkage of, or movement in the substrate.  Under no circumstances should the tiles be butt-jointed.  Kerakoll recommends the use of Fugabella Color grout which can be used on joints from 2 – 12mm, and is extremely durable, waterproof and colourfast with low Volatile Organic Compounds (GEV-Emicode 1).  All joints should be clear of adhesive as far as possible to avoid cracking of the grout where there is not adequate depth of coverage.

Movement joints should be filled with Silicone Color.

The same principles apply for wall tiles.  It is imperative that the substrate is totally solid and not flexible.  Tiling onto plywood is now outlawed by the British Standards and a suitable tile backer board should be used instead.  Any of the Biogel adhesives can be used to fix the tiles with Fugabella Color and Silicone Color for grout and movement joints in the same way as for floor tiles.

More details on the products can be obtained from the Kerakoll team, who will also be delighted to answer any questions and offer technical advice on particular projects.

The natural way to provide resistance to microbial attack

Many micro-organisms do not grow in environments with a pH value greater than 9 and the pH value of cementitious binders is higher than this. However, over time, their pH value drops due to salinification and this allows mould, fungi, and bacteria to grow.

There are various ways to limit the growth of such micro-organisms, although some of them engender other problems. The use of chemical, anti-mycotic and bactericide substances in the formulation of products for the building industry can lead to a wide range of diseases

and dysfunctions depending on the active principle used. That is to say that several of these substances, which to all intents and purposes are common pesticides, have been

classified as potential carcinogens based on their inherent toxicity and tendency to migrate and enter the atmosphere. While their use in farming is very strictly regulated,

there is no similar regulatory system governing their use in indoors, although it is the major area of exposure for most people. 

Rather than using harmful chemical substances to prevent the growth of micro-organisms, Kerakoll tackled the problem by pursuing alternative, natural methods. The company worked with researchers in the Microbiology Department of the CSTB (Technical Scientific Centre for Construction) in France to identify a way of using NHL (natural hydraulic

lime) to provide permanent resistance to the growth of bacteria and fungi.  

Samples of both Fugabella Color, Kerakoll’s resina-cemento hybrid grout range and Fugalite Bio, the company’s water-based resin grout range were tested by the CSTB and found to be B+ and F+, that is not to allow growth of either bacteria or fungi whether the grout is clean or dirty, making them a natural alternative to anti-bacterial treatments.
