Terrix® IP-ST-P
polymer-silicate interior paint
premium matt

Terrix® IP-ST-P paint is based on innovative Swiss technology combining silicate and dispersion binding agents. Due to its vapour permeable characteristic, it allows walls to receive and give off moisture naturally. In “wet rooms” (such as kitchens, bathrooms, laundry rooms, and basements), the excess moisture in the air may be easily reduced. Another essential property of the paint is its resistance to microbial contamination (e.g. black mould). Its very high Ph level offers natural and far better protection than other systems. The paint is resistant to cracking and flacking as its bonds o the substrate by chemical reaction; Traditional paints create a film on top of a substrate which can lead to peeling or cracking. Due to the lack of organic components in the paint and pigments used for colouring, Terrix® IP-ST-P
is a flame retardant. In contrast to most paints on the market and all standard emulsion paints, Terrix® IP-ST-P protects against the spread of flame. The mineral character of the paint makes it fully incombustible. The high alkalinity of the product delivers natural and long-lasting protection against algae and
black mould growth. The paint is very high resistance to wet scrubbing and washing. The product exceeds Category I (EN/BS EN 13300) requirements and is suitable for use in heavy-traffic areas. Spot repairs – the product can be easily spot repaired without leaving any visible patches, which is
usually impossible to achieve with all other deep matt or matt paints available on the market. Natural regulation of moisture levels due to microporous structure enabling the “free” travel of moisture and use of hygroscopic proprieties of the wall. Lower moisture levels mean less expensive heating and a lower risk of developing asthmatic health conditions.
Complies with BREEAM International (Exemplary) & LEED v4.1 low-emitting paint criteria.

Application

Substrate preparation:

The substrate must be stable (no scratches and cracks), degreased, clean, dry and free from stains and efflorescence of biological or chemical origin. In the case of microbial contamination, the substrate should be cleaned mechanically and then washed with a biocide solution to remove microbial contamination. Discolourations, nicotine stains, and efflorescence resulting from water seepage are to be initially painted with the Terrix® IP-SB stain blocker. All loose layers not connected with the surface (loose render or flaking paint coatings) are to be removed. The remnants of adhesive or lime paints must be thoroughly removed and washed with water.
New cement and limestone plasters can be painted only after a two-week seasoning and gypsum-based plasters after one week. Seasoning is not required for plasterboards.

Note: Directly before applying the paint, surfaces made from materials susceptible to alkalis (such as wood, metal, glass, or clinker bricks) should be protected against splashing.

Preparation:

The packaging contains a ready-to-use product. Before application, the product should be thoroughly mixed.

Note: Do not dilute. Mixing Terrix® IP-ST-P paint with other paints may affect the technical properties of the product.
The paint has an enhanced alkaline level; personal protective equipment (PPE) must be used to protect eyes and skin. Protective clothing should be worn during application. In case of contact with eyes, rinse immediately with plenty of water. If irritation occurs, consult a doctor.

Application method:

The preferred application method for this paint is airless spray. Under normal conditions one coat gives full coverage. If you apply with a roller or brush instead, make sure coverage is complete; for rollers use an 18 mm-pile fleece sleeve. Apply a second coat only if the customer specifically requires it, and only after the first coat has dried thoroughly.

Drying:

The drying time of one layer of paint (at a temperature of +20 °C and relative air humidity of 55 %) amounts to about three hours. Complete binding (hardening) of the applied paint takes place after a minimum of 24 hours. Closed rooms should be aired after painting until the distinctive smell is gone.

Note: Low temperature and high air humidity lengthen the drying time of the paint.

Useful hints:

Colour differences may be avoided by applying a single product batch to the entire wall or element in one working cycle. Product to be used with temperatures above +5 °C. 
All tools are to be cleaned with water after finishing work.
Low temperatures and high air humidity may have a disadvantageous influence on the shade of the coating.

Q&A

Terrix® IP-ST-P paint is an innovative premium polymer-silicate dispersion paint based on Swiss technology. It combines silicate and dispersion binding agents, making it highly resistant to wet scrubbing, washing, and microbial contamination like black mould. The paint adheres to the substrate through a chemical reaction, making it resistant to flaking and delamination. It is also flame retardant, vapour permeable, and LEED/BREEAM certified.

The paint can be applied by airless, roller or brush. However, to make the best use of all the qualities the product offers, it is recommended to use an airless spray application.

For most typical substrates, the use of a primer is not required. For substrates with very low absorption (e.g. ceramic subfloors, OSB), a special primer may be necessary.

For applications on non-standard substrates, please consult your supplier or the technical support team.

Terrix® IP-ST-P is vapour permeable paint which allows water vapour to pass through it.
This means that it does not prevent the movement of water vapour through the surface on which it is applied, which can be an important factor in preventing moisture buildup and mould growth inside a building.
In contrast, vapour-impermeable paint does not allow water vapour to pass through it, which can lead to trapped moisture and potential mould growth.

What does it mean that your paint is vapour permeable?

Terrix IP-ST-P is one-coat paint which doesn’t require a mist coat.

Terrix IP-ST-P paint can be applied by airless, roller or paintbrush application.
To take advantage of all the benefits that it offers, we recommend using the airless method.

Airless paint application uses a high-pressure pump to force paint through a small tip, atomizing the paint into fine droplets. This method is often used for large surface areas, as it can quickly cover a lot of ground and spray a consistent and uniform coat of paint.
It also typically results in less overspray and less wasted paint than brush or roller application.
Additionally, using airless sprayers can improve the quality of the finish, as they apply paint with a more consistent thickness and texture.

It takes around 2 hours to paint a two-bedroom apartment with Terrix IP-ST-P using the airless method.
Including preparation and protection, one person’s total time is about 6 hours.

The main reason why Terrix IP-ST-P  does not peel off is because of the way it is bonded to the substrate and the fact that it is permeable.

Typical emulsion paints mechanically bond to the substrate by forming a film on the surface. This type of bond is not permanent and, under adverse conditions, can lead to peeling.
IP-ST-P is chemically bonded to the substrate – a permanent bond that does not result in the formation of a separate layer.

Another reason for paint peeling is moisture in the substrate. As the moisture tries to escape by pushing against the paint, this damages the paint’s surface.
Terrix IP-ST-P is free of these problems due to its high vapour permeability and chemical bonding to the substrate.

Terrix IP-ST-P is one of the few non-flammable paints on the market with a reaction to fire category A.
The paint owes its properties to its mineral composition, which is inherently non-flammable, unlike acrylic and silicone emulsions of organic origin.

Terrix® IP-ST-P paint can be used in a wide range of areas, including wet rooms (kitchens, bathrooms, laundry rooms, and basements), swimming pools, and heavy-traffic areas. Its microporous structure allows it to be applied on not fully dry substrates, and its flame-retardant property makes it suitable for safety-conscious applications.

The preferred method of application for Terrix® IP-ST-P paint is using an airless spray, as it provides all the advantages of the paint and allows for a one coat application. However, if airless spraying is not an option, the paint can also be applied in two layers using a paintbrush or roller. For manual application, a fleece paint roller with a hair length of 18 mm is recommended. The second layer should be applied only after the first layer has dried.

The substrate must be stable, clean, dry, and free from stains and efflorescence of biological or chemical origin. Any microbial contamination should be removed with a biocide solution, and surfaces made from materials susceptible to alkalis should be protected against splashing.

Yes, if necessary, the paint can be diluted with a small amount of water (20-30% volume for the first coat and 5-15% for the second coat). The amount of water used should consider the type of substrate, drying conditions, and application technique.

The drying time of one layer of paint (at a temperature of +20°C and relative air humidity of 55%) is about three hours. Complete binding (hardening) of the applied paint takes place after a minimum of 24 hours. Note that low temperature and high air humidity lengthen the drying time.

The paint should be stored in its original sealed packaging in a cool, dry, and frost-protected room. After opening and using some of the contents, the packaging should be resealed, and the remainder of the product should be used as soon as possible. The shelf life of the paint is 12 months from the production date in factory-sealed packaging.

Yes, keep the product out of reach of children. Additionally, all tools should be cleaned with water after finishing work, and closed rooms should be aired after painting until the distinctive smell is gone. Low temperatures and high air humidity may have a disadvantageous influence on the shade of the coating.

Terrix® IP-ST-P paint is available in white and selected colours from the PCC colour chart, as well as custom pastel colours.

The paint has a noble matt finish.

The average consumption rate of Terrix® IP-ST-P paint is approximately 0.22 l/m2 (two coats on a smooth surface). Given that the paint comes in a 10-liter tub, you can calculate the coverage area as follows:

Coverage area = Volume of paint / Consumption rate Coverage area = 10 liters / 0.22 l/m2

Coverage area ≈ 45.45 m2

So, a 10-liter tub of Terrix® IP-ST-P paint can cover approximately 45.45 square meters with two coats on a smooth surface.

If applied using the airless spraying method, the consumption rate of Terrix® IP-ST-P paint would remain approximately the same at 0.22 l/m2. This means that a 10-liter tub of paint can still cover around 45.45 square meters of a smooth surface, even with the preferred airless spray application method.

average consumption rate is approximately 0.22 l/m2 (two coats on a smooth surface).

The paint can be applied when the air and substrate temperature is between +5°C and +25°C.

The paint is composed of a copolymer binder and potassium sodium silicate as its base binder, non-organic coloured pigments, and has a density of approximately 1.60 g/cm3. It can be diluted with water if necessary.

The paint is available in single-use plastic packaging of 10 litres.

Due to its microporous structure, Terrix® IP-ST-P paint enables the “free” travel of moisture and uses the hygroscopic properties of the wall. This natural regulation of moisture levels contributes to lower heating costs and a reduced risk of developing asthmatic health conditions.

Yes, the paint can be easily spot repaired without leaving any visible patches, which is usually impossible to achieve with other deep matt or matt paints available on the market.

Yes, Terrix® IP-ST-P paint can be used on plasterboards. New cement and limestone renders can be painted only after a two-week seasoning, while gypsum-based plasters can be painted after one week. Seasoning is not required for plasterboards.

Yes, Terrix® IP-ST-P paint can be used on a variety of substrates, including cement and limestone renders, gypsum-based plasters, and plasterboards. It’s essential to ensure the substrate is stable, clean, dry, and free from stains and efflorescence before applying the paint.

The high alkalinity of Terrix® IP-ST-P paint offers natural and long-lasting protection against algae and black mould growth. Its very high pH level provides better protection than other paint systems, reducing the risk of microbial contamination.

The VOC (Volatile Organic Compound) content of Terrix® IP-ST-P paint is categorized as cat A/a, containing less than 30 g/l VOC. This makes it more environmentally friendly and safer than paints with higher VOC content.

Terrix® IP-ST-P paint has excellent resistance to wet scrubbing. It meets the requirements of Class I paint according to the EN-C-81914: 2002 standard, making it suitable for use in heavy-traffic areas where frequent cleaning may be necessary.

Wet scrubbing resistance is a measure of a paint’s durability and its ability to withstand cleaning, specifically when using water and a brush, sponge, or cloth to remove dirt and stains from the painted surface. A high wet scrubbing resistance is a significant benefit for Terrix® IP-ST-P paint as it demonstrates the paint’s ability to withstand frequent cleaning without damage to its appearance or integrity.

Terrix® IP-ST-P paint has excellent resistance to wet scrubbing, meeting the requirements of Class I paint according to the EN-C-81914: 2002 standard. This classification signifies that the paint can endure a substantial number of cleaning cycles without showing any signs of wear or degradation.

This high level of wet scrubbing resistance makes Terrix® IP-ST-P paint an ideal choice for heavy-traffic areas, such as hallways, kitchens, bathrooms, and commercial spaces, where surfaces may need to be cleaned regularly. The durability of the paint ensures that it will maintain its appearance and performance even under frequent cleaning, providing long-lasting protection and an attractive finish.

The flame retardant property of Terrix® IP-ST-P paint contributes significantly to safety by reducing the risk of fire spread and minimizing the potential damage caused by fires. This characteristic is achieved by incorporating non-organic components in the paint and pigments used for colouring, which makes the paint less likely to support combustion.

There are several ways in which the flame retardant property of Terrix® IP-ST-P paint contributes to safety:

  1. Incombustibility: The mineral character of the paint makes it fully incombustible, meaning it will not catch fire or support the spread of flames. This characteristic can help prevent fires within a smaller area and prevent them from spreading throughout a building, potentially saving lives and property.
  2. Reduced smoke and toxic gas production: In the event of a fire, flame retardant paints like Terrix® IP-ST-P typically produce less smoke and toxic gases compared to conventional paints. Lower levels of smoke can improve visibility during the evacuation. At the same time, reduced toxic gas emissions can minimize the risk of injury or death from smoke inhalation.
  3. Enhanced structural integrity: The flame retardant property of the paint can help maintain the structural integrity of the building elements it’s applied to by slowing down the rate at which they are weakened by fire. This can provide additional time for occupants to evacuate and for emergency responders to intervene.
  4. Compliance with building regulations and codes: Terrix® IP-ST-P paint’s flame retardant property can help meet or exceed building regulations and fire safety codes, which often require using flame-resistant materials in certain areas, such as commercial buildings, schools, and hospitals.
  5. Insurance benefits: Using a flame retardant paint like Terrix® IP-ST-P may lead to lower insurance premiums, as insurers often consider the fire safety measures in place when calculating policy costs.

In summary, the flame retardant property of Terrix® IP-ST-P paint plays a crucial role in enhancing fire safety by reducing the risk of fire spread, minimizing smoke and toxic gas production, maintaining structural integrity, and helping to meet building regulations and fire safety codes. These benefits not only contribute to the protection of lives and property but may also result in financial savings through lower insurance premiums.

Yes, Terrix® IP-ST-P paint is suitable for use in areas with high humidity, including swimming pools. Its microporous structure, vapour permeability, and resistance to microbial contamination, such as black mould, make it an excellent choice for “wet rooms” where moisture levels are typically higher.

No, Terrix® IP-ST-P paint does not require a primer or mist coat before application. Its unique formulation allows for direct application onto a properly prepared substrate, saving time and resources during the painting process.
