TAFF INDEPENDENCE

PRODUCT DESCRIPTION

TAFF INDEPENDENCE removes all kinds of surface dirt (verdigris, algae, moss, lichens...) without high pressure, water or mechanical action, bird droppings and other organic soiling) from all water-bearing substrates. New soiling is avoided.

HOW FAST DOES TAFF INDEPENDENCE WORK?

The visible reaction depends on the nature of the substrate and the temperature and may not be apparent for several weeks. The sustainable Protective function acts for several years.

WHERE CAN YOU APPLY TAFF INDEPENDENCE?

TAFF INDEPENDENCE can be used on all water-compatible substrates: Walkways, pavers, patios, retaining walls, gabions, roof surfaces, concrete tiles, bricks, fiber cement, clay pots, tombstones, plastic, textile roofs, conservatories, awnings, etc....

HOW IS TAFF INDEPENDENCE APPLIED?

Coarse impurities are removed first. TAFF INDEPENDENCE is applied diluted (1:6) in dry weather by spraying or brushing. If the substrate is highly absorbent, the process may have to be repeated. The substrate should not be wet for at least 12 hours after application in order to avoid the Keep reaction active. The dissolved organisms and contaminants are gently removed little by little by weathering.

IS TAFF INDEPENDENCE DANGEROUS FOR HUMANS?

TAFF INDEPENDENCE is acid and chlorine free, but can still be used on the skin. Cause burns. For this reason, protective clothing, goggles and -wearing gloves. Do not eat, drink or smoke while working. Vapors Do not inhale.

TAFF PROTECT

PRODUCT&shyDESCRIPTION

The new paving stone protection TAFF PROTECT is a weather protection based on mineral ingredients for paving stones, sidewalk/patio slabs, concrete floors/-. walls and natural stones (also suitable for roof tiles and roof stones). It provides for a consolidation of the material, fills microcracks and closes open pores. With TAFF PROTECT, the surface becomes significantly more resistant to environmental influences and less sensitive to new soiling. The hydrophobic effect ensures that no water can penetrate the material and thus increases the service life. With TAFF PROTECT, a thin film of water is formed, which very quickly dries and thus does not form a basis for adhering dirt. In addition TAFF PROTECT is oleophobic (free of fluorine!), i.e. it has a dirt-repellent effect against greasy and oily soiling. The dirt remains only superficial and can be removed more easily. The treatment with TAFF PROTECT results in significantly longer protection against weather-related Contaminants.

WHAT IS CONTAINED IN TAFF PROTECT?

TAFF PROTECT weather protection contains potassium silicate, silicic acid, lithium salt, Dimethylsiloxane and potassium methylsilane triolate.

HOW LONG DOES THE WEATHER PROTECTION LAST?

Renewed soiling can of course not be prevented and the Timing is strongly influenced by external factors. Optimum protection against the environmental impact of industry and automobiles does not exist. An impregnation for example with TAFF PROTECT, however, ensures that the dirt particles, grease and Oils adhere poorly to the patio stones/yard surfaces and are washed away by the rain be Organic soiling such as algae, fungi and moss is very well prevented.

IS TAFF PROTECT HARMFUL TO THE ENVIRONMENT?

When used properly, there is no harm to the environment. TAFF PROTECT is only used on the surfaces to be protected and does not get into the Soil. Residues of the protective agent are disposed of as problem waste.

IS TAFF PROTECT DANGEROUS FOR HUMANS?

Users must wear protective gloves, protective clothing, eye protection and face protection. This is not necessary for residents of the object or passers-by. Direct contact with the product can, in case of improper handling, lead to lead to skin irritation. In case of contact with the eyes, these are to be cautiously for a few minutes rinse with water. If possible, any contact lenses that may be present should be removed and the eyes are further rinsed.

TAFF STAR

PRODUCT&shyDESCRIPTION

TAFF STAR is an alkaline cleaner designed for atmospheric soiling. Especially in urban regions with a lot of industry and car traffic fine dust and soot particles accumulate on the facade over time. For such soiling is a cleaning agent with strong solvent power towards greasy soot and dust particles is required. TAFF STAR meets exactly these requirements and is therefore an optimal complement to the proven TAFF ACTION.

WHAT IS INCLUDED IN TAFF STAR?

The detergent is a perfect mixture of various washing substances, complexing agents and corrosion inhibitors. This is a concentrate.

HOW LONG DOES THE CLEANING RESULT LAST?

Renewed soiling can of course not be prevented and the Timing is strongly influenced by external factors. Optimum protection against pollution from industry and cars does not exist. One impregnation for example with TAFF PRESERVE ensures, however, that the dirt particles are poorly adhere to the facade and are washed away by the rain. In individual cases, on-site be decided which facade protection is the most sensible.

IS TAFF STAR HARMFUL TO THE ENVIRONMENT?

All TAFF STAR ingredients are biodegradable.

IS TAFF ACTION DANGEROUS FOR HUMANS?

Direct contact with the concentrate can, in the event of improper handling, cause lead to mild skin irritation. The person concerned must, however, for longer Be exposed to the agent for a long time with large quantities. Spray mist in the eye or on the Skin is unpleasant, but not a concern at low levels. With a direct, concentrated jet into the eye, however, are absolutely rinsing measures required. A personal protective work equipment (suitable work clothes, Protective goggles, protective gloves and, if necessary, mouth protection) should be used by every user, as they come into contact with cleaning agents on a daily basis. For residents of the object or passers-by, this is not necessary.

TAFF ACTION

PRODUCT&shyDESCRIPTION

TAFF ACTION is an exceptional cleaning agent for any type of plaster and stone facades. The product contains a years of development and over ten years of application experience. TAFF ACTION lets the black-green and partly reddish Discolorations from the facade disappear and literally leaves a pore-deep clean result. Another special feature - and thus unique in its class - is its material-protecting properties.

WHAT IS INCLUDED IN TAFF ACTION?

The main ingredient is so-called "active chlorine". Just as with stubborn dirt stains on white textiles, it makes the unsightly discolorations disappear from the facade. Other ingredients include special corrosion inhibitors that largely suppress corrosion on aluminum, copper and galvanized steel during a normal cleaning process. Where other cleaning agents based on active chlorine leave damage, TAFF ACTION is particularly gentle on materials.

HOW LONG DOES THE CLEANING RESULT LAST?

Of course, re-contamination cannot be prevented and the timing is strongly influenced by external factors. However, independent studies have shown that the TAFF PRESERVE maintains the clean facade more than twice as long as without the corresponding Protection. In practice, this can mean three to five years. By the way, it does not matter whether the facade has been cleaned or repainted, the probability of re-contamination is the same and can only be influenced by the facade protection.

IS TAFF ACTION HARMFUL TO THE ENVIRONMENT?

As with any professional cleaning agent, the application of TAFF ACTION must be left to the professional company. Thereby should always only be worked in conjunction with the collection of facade wastewater. Only in this way can environmentally friendly cleaning be ensured be TAFF ACTION was developed for the large-scale treatment of facades and accordingly the ingredients are so low concentrated that no danger to the environment is to be expected, even in the event of an incident. The agent rapidly decomposes in the soil into water, oxygen and table salt. Even if the TAFF ACTION should get onto plants or objects in small quantities (e.g. by spraying), there are no long-term damage to be feared. The TAFF cleaning team ensures that green areas, bushes and vegetable gardens are watered or covered with tarpaulins before and after cleaning.

IS TAFF ACTION DANGEROUS FOR HUMANS?

Direct contact with TAFF ACTION may cause skin irritation if handled improperly. However, the person concerned must be exposed to the agent for a long time with large quantities. Spray mist in the eye or on the skin is unpleasant, but in small quantities not a cause for concern. However, in the case of a direct, concentrated jet into the eye, rinsing measures are absolutely necessary. The at the Cleaning sometimes occur "chlorine smell" is not harmful, because in the outdoor area is naturally very good ventilation. Windows must be closed during cleaning, not least for this reason, so that the odor does not penetrate into the interior. If the odor should be perceptible in the house, it can only be a very low concentration (comparable to a swimming pool, the odor threshold is very low). However, the TAFF cleaning team uses a fragrance that masks the unpleasant odor. There is a relationship between the smell of chlorine and the pollution on the facade. The higher the degree of contamination is, the more intense the smell can be perceived.

WHAT CAN GO WRONG WHEN CLEANING WITH TAFF ACTION?

Every facade is different! Despite trial area, it may happen in rare cases that the soiling on another area of the facade is more persistent and not can be eliminated 100%. Even with improper use, it is possible that despite corrosion inhibitors can cause damage to particularly sensitive metal elements. Such damage can usually be repaired by simple polishing. To ensure that this does not happen, TAFF cleaning technicians will provide appropriate Take precautionary measures (e.g. mask off sensitive components).

WHAT IF THE FACADE IS PAINTED LATER?

After rinsing, the application of TAFF ACTION does not affect any subsequent paint coat. TAFF PRESERVE has no influence on this either.

TAFF PRESERVE

PRODUCT&shyDESCRIPTION

TAFF PRESERVE is a disinfectant for plaster facades as well as painted facades of all kinds.TAFF PRESERVE adheres to the facade and penetrates deep into the pores.It effectively inhibits the re-infestation of algae and mold, thus providing long-lasting protection. TAFF PRESERVE is applied directly after cleaning with TAFF ACTION.

WHAT IS INCLUDED IN TAFF PRESERVE?

TAFF PRESERVE contains a WIrkstoff, which disrupts the metabolic functions of microorganisms and thus prevents the spread.

HOW LONG DOES THE CLEANING RESULT LAST?

Independent studies have shown that TAFF PRESERVE maintains clean facades more than twice as long as without appropriate protection. In practice, this means five to six years. By the way, it doesn't matter whether the facade was cleaned or repainted - the probability of new soiling is the same and can only be influenced by facade protection.

IS TAFF PRESERVE HARMFUL TO THE ENVIRONMENT?

TAFF PRESERVE was developed for the large-area treatment of facades and, accordingly, the active ingredient is concentrated so low that, with sufficient effect, the environmental impact is kept very low.

IS TAFF PRESERVE DANGEROUS FOR HUMANS?

TAFF PRESERVE has a targeted effect on microorganisms. There is no danger to higher organisms such as humans and animals.

WHAT CAN GO WRONG WHEN APPLYING WITH TAFF PRESERVE?

If places have been forgotten, there is a risk of premature algae and fungal growth there.

WHAT IF THE FACADE IS PAINTED LATER?

TAFF PRESERVE has no influence on the nature of the facade surface directly or properties such as water vapor diffusion and heat transmission. Later repainting is also possible without any problems.
