FAQ

• I would like to paint the silver metal staircase fence. Which colour from your sales programme would you recommend (primer and top paint)?

  You can paint the fence with the TESSAROL system following the procedure below:
  
  1. clean the rust and other impurities with sanding paper and degrease with TESSAROL NITRO thinner,
  2. apply 1 coat of white TESSAROL primer for iron or TESSAROL primer UNI to interior surfaces and 2 coats on exterior surfaces,
  3. apply 2 coats of basic silver shade of TESSAROL Antik 3in1 or TESSAROL Metal Express RAL 9006.
  
  Warning:
  All products can be applied with a brush, a roller or by spraying. As the indicated coatings contain metallic pigments, the most beautiful appearance is obtained by means of spraying as pigments are distributed equally without causing spots. When using a brush or a roller, spots can be formed on large surface areas due to an uneven distribution of pigments. If you wish to obtain a smoother surface that consequently enables easier cleaning, protect the TESSAROL Antik 3in1 coating with an additional coat of TESSAROL varnish matt (indoors) and TESSAROL varnish for boats (outdoors). Mix the coatings well before use with a flat mixing tool, and use them in accordance with the instructions in the technical documentation.
  
  You can see how the individual coatings look like on TESSAROL Antik 3in1 and TESSAROL enamel colour cards. The cards are available in all well-stocked stores with construction material which have the HGMIX mixing system. 

• We want to restore the iron door. Rust has already appeared in some areas. Which paint should we use to restore it quickly and effectively?

  The effectiveness of the iron door restoration depends on the precision of rust and dirt removal, as well as the number of layers applied to the surface. A greater number of layers (following the manufacturer's instructions) will prevent corrosive substances from penetrating the iron base for a longer period.

  For quick restoration of iron surfaces with minor rust spots, we recommend TESSAROL Direct 3in1, a product that serves as both a primer and decorative coating. TESSAROL Direct 3in1 is an enamel that protects the surface from rust while providing a glossy finish, similar to other enamels. It can be applied directly to a dry, sanded surface free of coarse rust particles, without the need for a primer.

  If rust has already affected the iron door, remove it along with any poorly adhered paint by sanding, and clean grease and other impurities using TESSAROL NITRO thinner. Then, apply TESSAROL Direct 3in1 enamel in two or three layers, allowing 6 hours between each layer. Use a brush, roller, or spray, and thin as needed with TESSAROL thinner. TESSAROL Direct 3in1 is available in six standard shades, with an additional hundred shades available in stores featuring the HGMIX mixing system.

  Alternatively, you can protect the door with TESSAROL primer and finishing paints. Thoroughly remove rust and poorly adhered paint by sanding, and clean grease and other impurities with TESSAROL NITRO thinner. Apply one or two layers of TESSAROL primer UNI or TESSAROL primer for iron to protect the base from rust. Over the sanded primer, apply two layers of TESSAROL Metal Express or TESSAROL enamel in the desired colour shade.

• Approximately 10 years ago, we completed our new building with a thermal insulation system based on mineral wool and dispersion silicone plaster. Now, very small but numerous cracks are beginning to appear in the plaster. We would like to renew the façade or protect it from further deterioration. What do you recommend?

  Since you have chosen a vapor-permeable thermal insulation, the most suitable façade paint for restoring your façade is SPEKTRA Renoxan. The composition of this façade paint enables reinforcement and bridging of microcracks; it is highly water-repellent and vapor-permeable. Additionally, it contains biocidal protection for the dry coating film, ensuring that the renewed façade surface remains protected from the regrowth of mould and algae for a longer period. Carefully selected, high-quality fillers and pigments provide high mechanical resistance, as well as UV and weather stability.

  Restoration System:

  1. Over time, significant dirt accumulates on the façade due to urban pollution, so we recommend first washing it with steam or hot water.
  2. Treat the façade surface with visible mould fully with biocidal agent SPEKTRA Sanitol. Apply the treatment approximately 1.5 m beyond the visibly affected area. Where there is no mould, the biocidal agent is not needed. Dilute biocidal agent SPEKTRA Sanitol with water at a ratio of 1:4. In cases of severe contamination, you can dilute it less or use it undiluted. Once the surface is dry, remove the mould by brushing. Repeat the process if mould is severe. Sanitol does not alter the appearance of the mould.
  3. After mould treatment, apply one layer of SPEKTRA Impregnation Acryl diluted with water in a 1:3 ratio (drying time: 12 hours).
  4. Next, paint the façade using SPEKTRA Renoxan façade paint. Two layers are required. The paint is available in various shades from the HGMIX EXTERIOR COLOUR COLLECTION and other colour charts.

  Note: biocidal agent SPEKTRA Sanitol is used on its own and is effective only during drying. Do not mix the agent with paint, as it will have no effect.

  Before using the products, read the instructions in the technical information.

• We would like to repaint a façade that was completed 10 years ago. There are no visible mechanical damages on the surface, but due to its construction (without an overhang), it is extremely exposed to moisture (rain, fog, morning dew). On the non-sunlit sides, the surfaces take particularly long to dry, so we anticipate that mould will eventually appear on them. Frequent direct exposure to moisture has also caused visible dirt streaks.

  Moisture, especially when it lingers on façade surfaces for extended periods, is the main cause of dirt, mould, and damage. Modern constructions without overhangs have aesthetic and energy-saving advantages but, unfortunately, do not resolve the problem of moisture. In the described situation, the most suitable façade paint for renovation is SPEKTRA Top Dry. This paint is characterized by extremely fast drying after rain, dew, or fog. On the coating, water disperses into very fine droplets that dry exceptionally quickly, even on less sunlit surfaces. Water absorption is minimal, keeping the façade dry and preventing the accumulation of dirt and the growth of mould. The paint also contains effective biocidal protection against mould and algae, preventing their growth for an extended period.

  Restoration System:

  1. Since dirt has accumulated on the façade over the past 10 years due to urban conditions, we recommend starting with washing it using steam or hot water.
  2. Any façade surface with visible mould should be fully treated with the biocidal agent SPEKTRA Sanitol. Apply the treatment approximately 1.5 meters beyond the visibly affected area. Where there is no mould, the biocidal agent is not needed. Biocidal agent SPEKTRA Sanitol is diluted with water at a 1:4 ratio. In cases of severe contamination, dilute it less or use it undiluted. Once the surface is dry, remove the mould by brushing. Repeat the process in cases of severe mould. Sanitol does not alter the appearance of the mould.
  3. After mould treatment, apply one layer of SPEKTRA Impregnation Acryl diluted with water at a 1:3 ratio (drying time: 12 hours).
  4. Follow by painting the façade using SPEKTRA Top Dry façade paint. Two layers are required. The paint is available in a variety of shades from the HGMIX EXTERIOR COLOUR COLLECTION and other colour charts.

  Note: Biocidal agent SPEKTRA Sanitol is used on its own and is effective only during drying. Do not mix the agent with the paint, as it will not have any effect.

• We have a new concrete fence and are wondering which product to use to paint it for the first time and also for impregnation.

  The concrete fence must have good waterproofing. In the event of direct contact with moisture, the water will eventually penetrate under the colour film. Due to differences in temperature, it will be subjected to different strain (frost) and consequently start cracking and peeling off.
  
  If waterproofing is taken care of, you have several options. We recommend using SPEKTRA Concrete Protect. Before first application, we recommend impregnation – best with SPEKTRA deep impregnation, or also with acrylic impregnation SPEKTRA Impregnation Acryl if the concrete is more porous. Apply two coats of paint using a roller or brush.
  
  Consumption: 1 liter covers 4–5 m² in two coats. Restriction: the temperature of the surface and the surroundings should not be below +5 °C.

• For our new house, we have decided to paint the façade in a dark gray shade, combined with lighter gray and white shades. The contractor informed us that dark shades are not recommended due to excessive heating of façade surfaces, which can lead to faster deterioration of the coating. However, due to the strong aesthetic appeal, we still wish to have the house in the selected shades. Is there a solution?

  Your contractor is correct. Dark shades absorb a large portion of the visible spectrum and an even larger part of the IR spectrum of sunlight, which is responsible for heating exposed surfaces. The darker the shade, the more it heats up. For each colour shade, we have calculated the Y value, which represents the percentage of reflected visible light, and the TSR value, which represents the percentage of total reflected sunlight. The Y value for dark shades is below 20, with the TSR value typically even lower.

  While the Y value cannot be altered, we can significantly increase the TSR value by using pigments that reflect the IR spectrum of sunlight instead of regular pigments. For selected dark shades in the HGMIX EXTERIOR COLOUR COLLECTION, we have developed formulas using IR-reflective black pigment rather than standard black pigment. These shades are available in SPEKTRA Top Dry façade paint.

  SPEKTRA Top Dry provides high-quality protection for façade surfaces, featuring extremely low water absorption and rapid drying after rain, fog, or dew. With reduced heating and high UV and weather resistance, even dark shades on your façade will retain their original appearance for an extended period.

• Where can one get the colour cards for your products?
  
  

  All our colour cards are available at our sales points with the HGMIX mixing system.

  The HGMIX mixing system enables the preparation of the selected colour shade based on a large number of colour cards, such as: INTERIOR COLOUR COLLECTION, EXTERIOR COLOUR COLLECTION, Monicolour 720, RAL, NCS and several others.

  
  The colour cards can also be obtained from different professionals we work with (painters, facade builders). For individual products, some shades and colour cards can also be seen on our websites.

   

• I am renovating a 30-year old apartment, which I want to repaint and later on also paint a couple of the walls with stronger shades. The walls do not have any particularities (no large stains or mould). We are expecting a baby so we would like to use a paint with no unpleasant odour or harmful substances. Which paint can you recommend?

  To paint indoor surfaces, we recommend SPEKTRA interior wall paints which are available in different qualities and shades. Given that there will be small children in the house, we recommend SPEKTRA Active Air interior wall paint, which breaks down up to 98 % of harmful formaldehyde in the air, creating a healthier living environment. The paint allows for wet cleaning, is highly vapor-permeable, provides excellent coverage, and can be ordered in any colour shade you choose. If you are happy with white surface and with a coating resistant to dry wiping, we recommend using SPEKTRA Extra, which is easy to apply and provides good hiding power.
  
  Each paint has also a certain scent of raw materials ‒ acrylic binders, which is typical for all water-based paints. The scent will remain in the room for a few days at most, until the coating is thoroughly dry. The paint is not harmful and is made in accordance with the latest standards of the European legislation.
