Decoupling & Crack Bridging Systems for Tiles

Decoupling Layer

When tiling floors with porcelain or ceramic tiles it is necessary to protect the tiled surface from movement and stresses in the underlying floor (the substrate) which can cause the tiled surface to fail or crack. Here are some of the reasons that can cause the substrate to move;

  • Thermal expansion and contraction. For example: the warming or cooling of a heated screed, or external temperature changes on a patio between day and night. Tiling behind large areas of south facing glazing are also particularly prone to movement.
  • Moisture movement in wooden floors. Wooden structures expand when humidity increases and shrinks when it decreases.
  • Shrinkage of a newly laid sand & cement, anhydrite or concrete screed. In the days and weeks after a new screed is laid it will shrink as it dries and cures.

Decoupling and crack bridging systems provide a layer between the tiled surface and the flooring substrate. This layer ensures that the stresses caused by horizontal movement are not passed on to the tiled surface, which may cause deformation and cracking.

Decoupling and crack bridging systems will not accommodate vertical movement and deflections, however. These are typically found in poorly braced timber floors, between adjoining substrates (i.e. a join between a timber and screeded substrate), or when covering an expansion joint. Timber floors must be well braced to prevent deflection (bounce).

In addition, expansion joints will generally be required over a substrate expansion joint or between adjoining substrates. Additional movement joints will also be required round perimeters, columns, over supporting walls and in large areas.

Always read the manufacturers detailed fixing instructions.

Most systems require fixing to the substrate, but BAL Flexbone2Easy is a loose lay system that speeds us install time. This can also be particularly useful if later refurbishment is expected, or you’re fixing over an anhydrite screed. Orbry and Marmox boards can be mechanically fixed to timber flooring and any fleece-based system can also be fixed to dry sand and cement screeds using Ardex AF200 vinyl adhesive.

We currently stock ten different De-Coupling and Crack Bridging systems that offer varying functionality and pricing. We offer solutions for low height systems, anhydrite screeds, easily removable, indoor or outdoor, integral waterproofing, fast tracking traditional screeds, vapour equalisation and integrated electric cable grids.

What Are The Differences Between Cement Based Adhesives?

Tile adhesive being applied for tiles

There are many different types of tile adhesive available today, each for a different purpose and application. Selecting the correct adhesive your job is of paramount importance to ensure your tiled surface looks great and remains strong and stable during its lifespan.

This help sheet only relates to cement based adhesives, excluding ready mixed and resin based options which have their own features and benefits. Cement based adhesives are primarily split into two different classes, C1 and C2 – but what do these mean?

C1 Cement Based Adhesives

C1 adhesives are basic cement based adhesives and not stocked by Tile Fix Direct. As these adhesives are generally not suitable for Porcelain tiles, the most common type of floor tile.

C2 Cement Based Adhesives

Improved adhesives that often have their polymers modified, resulting in increased adhesion and bond strength. This also adds a degree of flexibility as well as water repellent characteristics. This type of adhesive is suitable for most tile types and on a wide range of background surfaces.

Suffixes and Additional Adhesive Properties

These C1 and C2 adhesives may also have some suffixes after their name that tell you a bit more about the tile adhesive and indicate it’s additional properties. You may see some of the suffixes listed below, so we’ve created a handy guide to let you know what they mean!

F = Indicates that this tile adhesive is Fast Setting or Rapid Setting, shortening curing time and allowing you to grout and complete your project quicker.

T = This indicates that the adhesive is Thixotropic or Slump resistant/Non slip. This can be particularly useful for wall tiling as the adhesive will not slump with gravity and weight.

E = Indicates Extended Working Time or pot life and can apply to both fast setting and standard setting adhesive. Extended pot life means you don’t have to rush, and is particular useful when tiling larger areas or projects with a complex design where a lot of tile cutting is required.

S1 = The S rating relates to how Deformable the adhesive is. S1 tile adhesives are suited to most tiling surfaces subjected to limited movement or subject to vibration, such as well braced timber floors. S1 adhesives are the industry standard tile adhesives for flooring as they have flexibility and strong support for your tiles.

S2 = This indicates that the product is a Highly Deformable adhesive. A highly deformable adhesive may seem the ideal product for floors with more movement, however, the S2 adhesive doesn’t provide as much support to the tile as an S1 version. This means that thinner or softer tiles may not have the strength to cope with the deformable nature of the adhesive and a less than stable background.

British Standards

All adhesives conforming to British standards should have packaging marked with the appropriate adhesive coding e.g. C2 FTE S1. Using the suffixes above, we can tell that this product would be an Improved Cement Based Adhesive, Fast Setting, Extended working time with some deformability.

Product Feature: Lithofin Stain-Stop

Had enough of stained tiles? Look no further than Lithofin Stain-Stop. It will help protect all types of natural and engineered stone including polished marble, so the tiles will keep that freshly installed look for longer.

What Stain-Stop Does

Lithofin Stain-Stop is an impregnator that provides protection for porous natural stone and artificial surfaces. Lithofin Stain-Stop penetrates into the surface of the tile and coats the capillaries with an extremely thin, invisible film. Oil, grease and water cannot penetrate through this film and so are not absorbed into the tile, instead remaining on the surface. The dirt can then be easily removed without leaving stains.

Where to Use Stain-Stop

Lithofin Stain-Stop is ideal for protecting unglazed ceramics against stains and to help facilitate every-day maintenance. We highly recommended using this product in kitchens, bathrooms and other areas which frequently come into contact with water and oil.

How to Use Stain-Stop

  • The surface to be treated must be completely dry and clean.
  • Always test the product in an inconspicuous area prior to use.
  • On highly absorbent surfaces: evenly and generously apply Lithofin Stain-Stop with a brush or roller. Avoid foam.
  • After approx. 20 minutes, apply Lithofin Stain-Stop again to ensure that the entire surface is saturated. Then carefully remove all surface residues with a cloth.
  • Do not allow any product to dry on the surface.
  • On highly absorbent surfaces, a second application after approx. 24 hours may be necessary.
  • Attention! the liquid product must sink into the surface.
  • Dry residues will not be removable once product is fully cured.
  • Lithofin Stain-Stop can only be used on absorbent and completely dry surfaces. Glass, ceramics, wood, and other surfaces sensitive to solvents must be protected against splashes.
  • Application Temperature: the temperature of the surface should be between 5°C and 25°C. Switch off under floor heating.
  • Drying Time: most solvents will evaporate within two hours. The product will be fully effective after approx. 48 hours.

For invisible protection against staining and for aiding the maintenance of all natural stone surfaces, including polished marble, use Lithofin Stain-Stop. Perfect for use on wall and floor surfaces in the kitchen and bathroom, as well as on table tops, window sills and other sensitive surfaces. It’s even suitable for both indoor and outdoor use.

The 10 Tiling Tools You Need in Your Toolbox

Tile adhesive being applied

It is said that a bad workman blames their tools, so a wise one knows to keep their toolbox happy with what we think are the top 10 tiling tools any tiler needs.

  1. Tape Measure: Making sure you measure accurately is probably the most essential part of any tiling job. Once the tiles have been cut and adhered to the substrate, if the measuring was off to begin with then there’s no going back. It is therefore vital that you have a good quality tape measure (with no obscured markings) before you start and measure both the surfaces you intend to tile on to and the tiles themselves before moving on to the next task. We recommend measuring it all a second time, just to be 100% sure.
  2. Pencil: Pencils are often overlooked until you are in the middle of a tiling job and desperately need to mark up accurately, then they are like gold dust. Therefore, though it may seem a bit ridiculous to have placed pencils in our top 10 list, you’ll be very thankful when you reach for that pencil and there’s one waiting for you. We recommend investing in a pack of chinagraph pencils – they’re great for marking on hard, glossy surfaces such as ceramic and porcelain.
  3. Manual Tile Cutter: The tool in your toolbox which will most likely become your most treasured is the manual tile cutter. Powerful, versatile and easy to use it can transform your hardest project into a walk in the park. With a manual tile cutter, the cut will be clean and precise, and it won’t affect the quality of the surface material, whether you’re working with ceramic or porcelain.
  4. Tile Spacers: Picture this, the perfect tiles have been selected, the cut and lay is just right, but when you go to grout you realise the spacing is a disaster – it’s every tilers nightmare. All this can be avoided with just a few small tile spacers. These tile spacers help you create equal space during the tile installation, by pushing between four corners of adjoining tiles or being turned on edge and positioned where the edge of one tile sits atop of another. We sell T, Y and X tile spacers so there’s no need to try and adapt them for an unusual shaped tile.
  5. Tile Trowels: No matter what type of tile you are installing, you’ll need to fix them to the surface with some form of tile adhesive . The tile trowel means you can apply the mortar cleanly and evenly to get the best, most professional finish. There are many different options available to suit the tile size and material – one option we love is the Genesis Trowel Set which comes with a range of interchangeable blades so you’ll always have the one you need handy.
  6. Tile Levelling System: There is a fine art to creating a perfectly level tiled surface, and sometimes you need a bit of help getting it. To avoid lipping and achieve the best possible finish a tile levelling system really is an irreplaceable tool.
  7. Grout Float: Comprising of a flat rubber base topped off with a handle, a grout float, similar to a kind of trowel, is used to press the grout into the gaps between your freshly laid tiles. The rubber part prevents damage to the tiles when applying grout. A grout float is an essential tool for those wanting to achieve a professional finish.
  8. Mixing Paddle: Whilst this tool is not considered by everyone to be essential, it is always a good one to have on hand. Whilst you can mix grout and adhesive with an improvised stirrer like a trowel, having the equipment designed for the job will make your life much easier. Mixing paddles are normally made form steel and are designed to fit most power drills.
  9. Sponge: It is the end of the job, the adhesive has cured, the grout has taken hold between the tiles, but it’s likely that there is grout over the surface of the tiles as well. This is where a heavy duty sponge comes in handy – it means you can clean up as you go. We recommend purchasing a proper, dense-celled sponge to remove any excess grout without pulling it out of the joints.
  10. Bucket: Alongside the sponge a proper bucket (not just any old washing up bowl) can help minimise any mess you will make during the tiling process. By buying a proper sturdy bucket, and having a sponge on hand, you can radically reduce your post-project clean-up. A bucket is also essential for mixing up grout and adhesive – pick a good one with with measurements printed on the side to make life easier.

So, there it is, the 10 tiling tools we think of as essential. By keeping all these crucial tools in one place you’ll save both time and energy (no digging through the back of your van for a tape measure or having to go to the nearest DIY store), meaning you can focus on the tiling project at hand.
