Why Kerakoll? The system behind a tidy tile job

Why Kerakoll? The system behind a tidy tile job

Why this brand · Kerakoll #1 · The brands Saniso stocks, and why  

Walk onto a tiling job in the Netherlands and there's a good chance you'll see the green-and-white Kerakoll buckets and bags. Why do so many tilers, and more and more DIYers, stick to this one brand from the first coat of primer to the last bead of sealant? In this first edition of our new series Why this brand we look at the Kerakoll tile system: where the brand comes from, how primer, adhesive, grout and sealant fit together, what makes the brand strong (in a reader-friendly SWOT), and which Kerakoll products you can order at Saniso today.

In short

Who: an Italian manufacturer from Sassuolo, founded in 1968, specialised in tile adhesives from day one.

Why a system: primer, adhesive, grout and sealant from one maker, with one colour code for grout and sealant.

Colour: 50 KK colours, shared by Fugabella Color, Fugalite Color and Silicone Color.

Adhesives: from a classic gel adhesive in a bag to a ready-to-use bucket and a hybrid gel for demanding jobs.

At Saniso: 8 Kerakoll products in this guide from €17.55, prices incl. and excl. VAT.

Who is Kerakoll, and where does the brand come from?

Kerakoll was founded in 1968 by Romano Sghedoni in Sassuolo, in the heart of the most important ceramic district in Italy. The name says it all: it combines the Greek kéramos (ceramic) and kólla (glue). The company started with tile adhesives, and the H40 name you still see on its best-known gel adhesive goes back to the 1970s, when Kerakoll launched H40 Flex for porcelain stoneware tiles. In 2010 it adopted the tagline The GreenBuilding Company, and in 2023 it obtained B Corp certification. The full sustainability story is already on our blog, in the article on how Kerakoll approaches green building, so here we focus on what the brand means on your tile job.

Why do tilers choose one brand for the whole tile job?

A tiled wall or floor is a stack of layers: substrate, primer, adhesive, tile, grout and sealant. When every layer comes from the same manufacturer, the products are developed and described with the same approach. You read one style of technical data, you work with one colour code for grout and sealant, and you have one logic for the whole job. For a tiler that means fewer questions on site and a finish that looks the same in every room. For a DIYer it means one clear shopping list instead of a shelf full of guesswork. Many Kerakoll packs also carry the brand's own GreenBuilding Rating, a quick way to see the product's environmental profile at a glance.

What does the Kerakoll tile system look like, from primer to sealant?

Here is how the layers fit together. The full step-by-step method for tiling (layout, notched trowel, spacers, grouting) is already explained in our guide on how to tile a wall, step by step, so we keep this to the brand overview.

What are Kerakoll's strengths and opportunities for your tile job? (a positive SWOT)

A SWOT usually looks at a brand from a boardroom. We wrote this one for the person holding the trowel: what the brand does well, where it opens doors for you, where it fits best and why we stock it.

Strengths

  • One maker for every layer: primer, adhesive, grout and sealant that are developed side by side.
  • One colour language: 50 KK colours across Fugabella Color, Fugalite Color and Silicone Color, so the sealant matches the grout.
  • An adhesive for every situation: a gel adhesive in a bag (H40), a mineral classic (Bioflex), ready-to-use (Biogel Ready) and a hybrid gel (Biogel Extreme).
  • Healthy to work with: the product pages of H40 Gel and Bioflex mention very low VOC emissions.
  • Experience: more than 55 years of tile adhesives, from the heart of Italy's ceramic district.

Opportunities

  • Large-format tiles: H40 Gel is suitable for formats up to 3000 × 1500 mm, ideal for today's popular big slabs.
  • Coloured joints: dark, warm and stone-look joints are popular, and with the KK palette every corner bead matches.
  • Renovation: deformable adhesives such as the Biogel range are made for substrates that move.
  • Conscious building: clients who ask about healthier, more sustainable materials will recognise B Corp and the GreenBuilding approach.

Where Kerakoll fits best

  • Bathrooms and showers, where grout, sealant and waterproofing have to work as one.
  • Kitchens and splashbacks, especially with stain-proof Fugalite Color.
  • Large floors and walls with big porcelain tiles.
  • Pools, spas and saunas, which the product pages of H40 Gel and Silicone Color name as suitable.

Why Saniso carries Kerakoll

  • It completes a full tile job in one cart: tiles, Kerakoll products and tools from our range.
  • Clear prices incl. and excl. VAT, so both pros and private customers see what they pay.
  • A wider Kerakoll range is available on request: add products to your Project List for a bulk quotation.
  • Thousands of products in stock in the Netherlands and next-workday delivery when it fits in a parcel.

How do you start the Kerakoll way: with a primer?

A primer is the step people skip most often, while it decides how well everything on top of it holds. It binds dust, evens out how much moisture the substrate draws from the adhesive and helps on smooth, non-absorbent surfaces. Check the technical sheet of your adhesive for which substrates need a primer.

Active Prime Fix 5 kg (Kerakoll primer)

Active Prime Fix 5 kg (Kerakoll primer)

What is it for? The first coat on a dusty, porous or very smooth substrate, so the adhesive or levelling compound that follows gets a good grip.

How do grout and sealant end up in exactly the same colour?

This is where the system really shows. Every KK code exists as Fugabella Color (resin-cement grout), Fugalite Color (waterproof resin grout) and Silicone Color (sealant). Pick your colour once, and the joints and the corner beads match. Which colour suits your tiles is covered in choosing the right grout colour, and the choice between the two grouts in Fugalite or Fugabella. A full overview of the colour system is in Kerakoll Color Fill: grout and sealant.

Is Kerakoll also a good choice for DIYers?

Yes. The same products tilers use are easy to work with at home. H40 Gel and Bioflex don't slip down the wall, so tiles stay where you put them. Biogel Ready needs no mixing at all, perfect for a weekend job. And because grout and sealant share one colour code, you don't have to match colours by eye in the shop. Order primer, adhesive, grout and sealant in one go and you have everything on site before you start. New to tiling? Follow our guide on how to tile a wall, step by step.

How much Kerakoll adhesive do you need?

The product pages give the coverage per square metre per millimetre of adhesive bed. A worked example with H40 White Gel (about 1.2 kg/m² per mm): a 10 m² wall with a 4 mm bed needs about 10 × 4 × 1.2 = 48 kg of adhesive. Add a little extra for waste, and check the bag size on the product page. For grout, the amount depends on tile size, joint width and joint depth: ask us or check the packaging before you order.

Which tips help you get the most out of the Kerakoll system?

  • Choose the grout colour first, then order the Silicone Color with the same KK code straight away.
  • Read the technical data of the adhesive before you start: open time, bed thickness and substrate.
  • Prime dusty or very smooth substrates with Active Prime Fix.
  • Clean resin grout with the matching Fuga cleaners while you work.
  • Order everything in one cart, so the whole job arrives together.
