Description of workflows and layer orders:

1. Preparation

To degreas the tile, you can use Triso, dissolved in lukewarm water or any degreaser. Wash the tile thoroughly with clean water after dissolving grease and other impurities. Wipe it dry. Make sure to wipe the remnants of the degreaser (veil layer) from the dried tile thoroughly with a dry cloth after washing the degreaser.

2. Glazing

In order to create a nice straight base, easier glazing and bridging the movement of the tile, it is recommended to embed a construction net in the HARZO tile filler, which is also used for façade insulation.

The net shall be cut to size so that it is about half an inch to 1 centimetres from the bottom and top of the sidewall. About 10 cm out of the width of the stripped mesh, the tiled bricks should be aerated. After the net has been removed, it must be placed in this filler and smoothed with stainless steel, pushed into the net, then pulled off the excess and put back in the bucket. Then place the next net next to it in the same way, just DO NOT  overlap it, about half an inch between the two nets. The same should be done on a walking surface, but here it is worth cutting the net into 60 cm bands, so that it is easier to touch the net by hand when kneeling and bending.

Its drying time is about 4-8 hours, with an air temperature of 20-22 °C and adequate ventilation and ventilation. All the meshes you need to embed should be scaled before glazing, so that you don’t have to worry about this when glazing!

TIP: In the case of a sidewall, when inserting the mesh into the HARZO tile ball, care should be taken to ensure that it is hung from above and smoothed into the upper part with a spatula, filler iron that will hold the net and you can embed it in a smooth way down.

After drying, small protruding pieces and cans can be scraped with a spatula or sanded and dusted. After dedusting, the HARZO tile filler should be smoothed the surface a second time. If errors are still found, they must be repaired (floked) with the tile glare. It is advisable to pull tiled material into the corners, do not have a cornered design, but rather curved, because this will make it easy to introduce the grout tape into the corners nicely.

Its drying time is about 2-3hours, with an air temperature of 20-22 °C and adequate ventilation and ventilation. Coverage: approx. 1.5-2.5 kg/m2/two layers  (second layer thinner).

Tile filler packaging:

  • 6 kg
  • 20 kg

3. Deep foundation

After the HARZO tile ball is dried, grinding, dedusting, washing, drying and deep foundation, HARZO basic with Penetrating Primer. It can be applied with a roller, but it is better to work with a brush and disc brush. There’s plenty to applicate, you can’t save on the material!  The HARZO Penetrating Primer should not be diluted with water in this case!!

Its drying time is about 2-3hours, with an air temperature of 20-22 °C and adequate ventilation and ventilation. Coverage: 10-12 m2/litre/layer.

4. Applying interstice color (in case you want to create an optical interstice)

Then, according to your needs, the white or colour-mixed HARZO Interstice color primer paint can be applied evenly, in one layer with a brush in the corners and edges, or with a short-haired roller (about 10-15 mm thread length) on larger surfaces. We recommend using the Schuller brand’s MICROLINE PRO 17mm hair-length paint roller and high-quality brush!

You can dilute the material by adding up to 5% water with a thorough mixing.

Drying time is about 2-4 hours with air temperature 20-22 °C and adequate ventilation and ventilation. Coverage: 10-11 m2/litre/layer.

  • 4 lit

5. Interstice design (in case you want to create an optical interstice)

Next comes the determination and measurement of the optical interstice, the gluing of the Scotch 3M interstice adhesive tape, which can be scaled as desired, using a laser or water level. You should not draw a continuous pencil line, because you will be able to see it in the design of the fuses!! It is enough to place one or two markings on the wall at the horizontal grout measurement in the corners and between them, at the vertical it is necessary to mark only at the top and bottom and glue the Scotch 3M tape along these markings. Care should be taken to ensure that there is no tension in the belt in the corners (do not jump out of the corner), so you should carefully introduce the interstice adhesive tape into the arc formed in the corners (which you have formed with a new one at the glazing) and follow the marking and smooth the tape thoroughly on the base.  Always stick the grout tape beyond the tile, the door tree, the painted surface, etc. basically where there are no tiles anymore, where you have not applied any material and you will find the grouting tape even when it is covered with texture material!

Dimensions of Scotch 3M adhesive tape: 58 m long and 3.17 mm wide.

6. Preparation of the texture (you can also create color separations)

HARZO 3 structure paint, which is blended to any color, is applied in a thicker layer with a painting roller

(recommended hair length approx. 15mm), with any pattern that can be further shaped in a variety of ways using stainless steel glazed creatively. Before creating the final pattern, it is worth rehemphasing the patterning on a piece of sample board and drywall, and then start working on the smaller simpler parts of the work surface!

You can make color separations after the texture is drying using masking tape or repaint the texture neck with e.g. HARZO Color overcoat or HARZO Interstice color primer to create colors.

We recommend using the MICROLINE PRO 17mm hair length paint roller of the Schuller brand and a high-quality brush!

Drying time is about 6-8 hours with air temperature 20-22 °C and adequate ventilation and ventilation. Coverage: 1 m2/kg/layer.

7. Varnishing

After the HARZO 3 structural paint dries, the last minor repairs can follow, and then the mixing and apply of the HARZO two-component water varnish.

Mixing of varnish begins with the mixing of component A, then the agitation and mixing of components A and B is followed by a clean bucket with a clean mixing mud, stirring for 5-6 minutes so that the chemistry processes start. Conveniently, you have about 2 hours to apply the varnish, after which the varnish begins to dry into the bucket. Always work with a clean roller, brush and scraper grid!! For varnishing, it is worth applying a new roller, brush, scraper grille per layer if you cannot wash it thoroughly!  We recommend using the Schuller brand’s MICROLINE PRO 17mm hair-length paint roller and high-quality brush for varnishing!


To the first layer you need to add 5% water, which you need to mix and aerated.  Then after 2-3 hours of drying, you need to applicate it again, but without adding water. Even after adhering to the second layer, provide a minimum drying time of 2-3 hours.

Until you know the behavior of the material, always applicate one part of the wall at a time, and then the next part of the wall. Handle the two-component varnish carefully!! If it is necessary to divide the varnish, measure it in several directions, use a digital household scale for weighing and take care to ensure that the weight ratios are accurately observed.

Drying time per layer: about 2-3 hours, which depends on the air temperature and ventilation possibilities.

Coverage: 10-12 m2/kg/layer Packaging.

  • 1 kg (component A+B)
  • 4 kg (component A+B)

8. Care, polishing

The HARZO Liquid Polishing Care seals the micronous pores of the dried varnishes, which are not visible to the naked eye, and protects them from abrasive effects and forms a protective layer, which is very easy to clean and keep clean. Countless layers can be applied one after the drying. With the care, you can care for the surface every week, monthly, yearly, over and over again, ensuring its shine and the experience of cleaning it effortlessly.

HARZO Polishing-Care water-like, white liquid that becomes colourless after drying. In two to three layers of completely dried varnish, it is necessary to work with the application of a microfiber mop, evenly dissiccating it. The Liquid polishing care can be applied to the side wall with a short-haired (approx. 10 mm hair length) paint roller, or rolled up on the mopp, and then evenly distributed with a mop on the side wall.  Make sure it doesn’t happen!!

Drying time between layers is about 30-40 minutes, depending on the temperature.

Its coverage is about 60 m2/litre/layer.
