ROAD MARKING

Acrylic and alkyd paint for road marking

Thanks to their quick-dry feature, these one-component paints are trafficable after a short period of time.

Suitable to be added glass beads. When applied on asphalt surfaces, they do not produce bleeding or attack the substrate.

Practical tips

- Concrete or asphalt surfaces must be clean and dry and free of grease or other contaminants.

- Wash with detergent and warm water.

- Do not wash with solvents, gasoline or diesel as they dilute grease and introduce it into the substrate.

- On very smooth surfaces with low porosity, apply muriatic acid 30/40% in water. Let dry and rinse.

- Some surfaces, such as ferrocement ones, are not attacked by acids and do not provide any type of adhesion. In those cases, grind with a 60 or 80 grinding wheel to generate mordant.

- Since these paints are affected by hydrocarbons, they mustn’t be used in service stations, in the areas where major spills may occur.

Information about fuels

• To make them reflective, 300 grams of beads should be added per liter. Mix gently to avoid breaking them.

• Apply at a room temperature higher than 10° C and a relative humidity below 80%. The substrate temperature must be 3° C above dew point.

• Apply with brush, roller or airless equipment.

• Leave a dry film thickness of 200 microns. This requirement is essential to the durability of the signage. Dilute, if necessary, only with multipurpose solvent (Multiuso).

Practical tips

• New metal surfaces must be deoxidized and phosphatized. To ensure greater protection from corrosion, apply a coat of antirust epoxy. 35 microns.

• On non-ferrous metals (galvanized and aluminum), previously apply a veil of wash primer.

• On new wood, it is advisable to apply a previous coat of fire-resistant impregnate (Impregnante Ignifugo) to provide greater protection against fire, reducing its flammability.

• After drying for 48 hours, apply white primer (Fondo Blanco Mano Previa) to deliver a uniform absorption.

• Let dry for 48 hours and sand to obtain a smooth surface.

• In repainting work, remove loose paint.

• If the existing paint is in good condition, it should be cleaned and then sanded lightly to matt and facilitate adhesion.

• Dilute the fire resistant enamel (Esmalte Ignifugo) with the indicated multipurpose solvent (Multiuso).

• Aplicar con soplete en capas finas para evitar arrugado y remoción de las pinturas anteriores o fondos aplicados.

• For the same reason, if necessary, retouch or apply a second coat, let dry for a minimum of 16 hours.

• On intumescent paints, it is recommended to wait for 24 hours before applying the fire resistant enamel after the last coat of intumescent coating.

IMPORTANT

* Intumescent paints and varnishes provide better fire protection to metal, wood, concrete or masonry structures and surfaces, isolating them from the effects of fire and temperature for a certain period of time.

* Steel protection is achieved with intumescent paints applied in high dry film thickness. The levels of thickness are determined by several factors such as: whether it is a beam or a pillar, the type of profile, the size, the number of faces exposed to fire, its massiveness, etc. Therefore in these cases we recommend prior consultation to the technical department.

* Intumescent paints and varnishes are not suitable for surfaces exposed to mechanical stress or traffic.

* The dilution of intumescent and fire resistant varnishes and enamels should only be made with multipurpose solvent.

Esmalte Ignífugo Esmalte Ignífugo

FIRE-RESISTANT WOOD IMPREGNATE

Impregnate suitable to reduce the flammability of cellulose fibers (wood, straw).

It does not contribute to the spread of fire nor to its transfer to other materials and so it increases the time available to combat it in its early stages and evacuate the affected area.

When applied on combustible materials which are rich in cellulose fibers it reduces their flammability. They mustn’t have pretreatments or previous coatings that may prevent the penetration of the product into the fibers.

The treated materials should be protected by a suitable coating, i.e. fire resistant varnish or enamel, according to the desired finish, transparent or pigmented, since water soluble materials may be affected by rain or splashes, losing the effect of the impregnate. In those cases, the process should be repeated and properly protected.

Important information

- Color: slightly colored

- Finish: transparent

- INTI test on wood: RG-1067/8

- Performance: 2 to 5 m2 per liter, depending on the absorption of the material to be treated.

- Number of coats: as many as it absorbs, generally three.

- Drying: 2 hours, depending on the environmental conditions.

Application

» Apply with roller, brush, conventional spray gun or airless spray gun, sprinkling or immersion.

Practical tips

• The product is supplied ready for use. Its dilution is not advisable.

• Cleaning solvent: water.

• The surfaces to be treated must be perfectly clean, dry, free of grease or previous treatments that might limit the impregnation of the material to be applied.

• In the case of wood previously varnished, impregnated or painted with synthetic products, these must be eliminated completely by chemical or mechanical means to reach the absorbing surface.

• On outdoor surfaces, do not apply when there is high humidity or temperature or in case of imminent rain.

• Always protect the treated surface with suitable coatings.

Importante

* Intumescent paints and varnishes provide better fire protection to metal, wood, concrete or masonry structures and surfaces, isolating them from the effects of fire and temperature for a certain period of time.

* The application of this type of intumescent coatings can be performed on new surfaces or on surfaces with previous paint in good condition, i.e. surfaces which are not peeling off. When it is desired to give wood a translucent finish, the intumescent varnish can be applied on the virgin wood treated with the fire resistant impregnate, leaving a dry film thickness of around 250 to 300 microns and, later on, protecting it with two coats of fire resistant varnish.

* In the case of varnished wood, the surface must be cleaned and sanded until a uniform matt surface is achieved to generate mordant. Then apply several thin coats of 250-300 microns of intumescent varnish. Always protect with fire resistant varnish.

* Intumescent paints or varnishes are not suitable for surfaces exposed to mechanical stress or traffic.

* The dilution of intumescent and fire resistant varnishes and enamels should only be made with multipurpose solvent.

Practical tips

• Surfaces must be clean, dry, firm, and with the appropriate mordant to facilitate adhesion.

• Ferrous metals must be previously protected with antirust epoxy (Antióxido Epoxi), Zinc ethyl silicate corrosion inhibitor (Inhibidor de corrosion zinc Silicato de etilo) or Zinc Rich.

• Aluminum and Galvanized surfaces are pretreated with Wash Primer to generate mordant.

Since standard antirust products and converters might be removed by the enamel’s solvent, their use is not recommended in these cases.

• On new walls, cementitious walls, fiber cement walls or similar it is advised to previously apply epoxy primer.

• In the case of epoxy or polyurethane paints in good conditions, they only need to be cleaned and sanded to matt and create mordant. Remove dust.

• If we ignore the nature of the previous coating is unknown, apply a coat of epoxy intermediate adhesive (Adherente Intermedio Epoxi).

• Stir A and B components separately and with clean spatulas until they are completely uniform. The contamination of the separate components by mixing them should be prevented.

• Mix three parts of component A with one part of component B. Stir with a clean spatula until the mixture becomes uniform. Prepare only the amount of mixture to be used.

• Let stand for 20 to 30 minutes to allow the induction of the reaction.

• The final properties of the applied enamel depend on the mixture accuracy and uniformity, as well as on the induction time.

• At temperatures above 25° C the product begins to lose its properties after 4 or 5 hours. At temperatures below 25° C, the usage time increases considerably.

• Do not apply when the temperature is below 7° C. Low temperatures and high humidity seriously delay the drying process. In this cases, it is advisable to heat the atmosphere.

COLOR SYSTEM

Practical tips

• Ferrous metals must be previously protected with antirust epoxy.

• Aluminum and Galvanized are pretreated with Wash Primer to generate mordant and then the antirust epoxy is applied to ensure a better finish.

• Since standard antirust products and converters might be removed by the enamel’s solvent, their use is not recommended in these cases.

• In the case of glass fibers, dry sand smoothly.

• Clean with acetone or solvent and immediately apply a coat of epoxy antirust as a sealer.

• On existing epoxy or polyurethane paints in good condition, it is only necessary to clean well and sand to matt and create mordant.

• If we ignore the nature of the previous coating is unknown, apply a coat of epoxy intermediate adhesive (Adherente Intermedio Epoxi).

• Stir A and B components separately and with clean spatulas until they are completely uniform. The contamination of the separate components by mixing them should be prevented.

• Mix three parts of component A with one part of component B. Stir with a clean spatula until the mixture becomes uniform. Prepare only the amount of mixture to be used.

• The final properties of the applied enamel depend on the mixture accuracy and uniformity.

• At temperatures above 25° C the product begins to lose its properties after 4 or 5 hours. At temperatures below 25° C, the usage time increases considerably.

Poliuretano Poliuretano

In the case of concrete floors or cementitious layers, they must be properly built allowing for the application of a vapor barrier under conditions that ensure complete waterproofness.

The concrete must be perfectly dry and cured, so leave a minimum two-week interval after the last section is finished. In any case, we recommend a preliminary test to determine the existence of moisture residue. Use the electronic moisture meter to determine the surface moisture, or proceed according to ASTM D-4263-83 standard: place a polyethylene film of approx. 1/2 m or similar, sticking it to the floor with masking tape around its perimeter and, after a minimum of 24 hours, remove and observe if there is any moisture condensation.

• If water drops appear, it is recommended not to apply any product and to wait for a few days before repeating the test. The polyethylene film may be replaced by a flat glass pane.

» Floor cleaning and decontamination:

The floors to be treated must be perfectly clean and free of grease or oil. Therefore, wash with Biodegradable Degreaser Cleaner Recufloor (Recufloor Limpiador Desengrasante Biodegradable) according to the degree of contamination present. In highly contaminated floors, apply a solution of 1 part of water and 1 part of Degreaser Recufloor. In slightly grimy floors, apply a solution of 1 part of Recufloor and 4 of water. Preferably, use warm water to apply the degreaser; rub vigorously and let work for about 15-20 minutes, then wash the resulting dirt away with warm water. Repeat the procedure until the surface is completely clean and let dry for 48 hours at 20 degrees Celsius.

» Muriatic acid treatment:

Apply a 40% muriatic acid in water solution in a way that the classical reaction of the cement (bubbling) is seen. This treatment seeks to give adequate floor roughness so that thin coating films adhere. Let work for a few minutes, and wash the rest of the reaction away with clean water. The roughness of the floor should be that of rough sandpaper. Repeat the procedure as many times as necessary until the desired result is obtained. If you do not want to rinse the surface, an industrial vacuum cleaner may be used to remove the dust.

» Abrasive cleaning for coatings of low and middle thickness

Sweep with fine sand or grit at low pressure to remove debris and contamination and to obtain a texture similar to that of thick sandpaper, without harming the substrate. In the case of high thickness coatings, scarify the surface to completely remove the surface layer and leave the stone exposed or remove any previous coatings. Try not to produce serious surface damage. Once the work is done, clean and remove the dust and debris with a vacuum cleaner or by sweeping.

For walls, follow the same directions as for floors regarding moisture, pollutants, loose parts, etc.

In both cases, if the surface requires it, apply epoxy primer to seal absorbent substrates.

The surface must be clean, free of grease, oil or other pollutants. Therefore, proceed to prepare the surfaces according to the required cleaning degree, respecting the specifications developed by the Steel Structures Painting Council which comprise the different cleaning degrees:

• SSPC- SP1 (solvent cleaning)

• SSPC-SP2 (cleaning with manual tools)

• SSPC-SP3 (cleaning with mechanical tools)

• SSPC-SP4 (flame cleaning)

• SSPC-SP5 (white metal abrasive blast cleaning)

• SSPC-SP6 (commercial abrasive blast cleaning)

• SSPC-SP7 (quick sweep abrasive blast cleaning)

• SSPC-SP8 (cleaning with chemicals, pickling)

• SSPC-SP10 (near white metal abrasive blast to cleaning)

• SSPC-SP11 (mechanical cleaning to bare metal)

• SSPC-SP 14 (industrial abrasive blast cleaning)

Oxide, including black oxide, must be completely removed, either by mechanical or chemical removal methods. We suggest Sa 2 1/2 finish.

We do not recommend using rust converter products for industrial maintenance.

In the case of aluminum, solvent, steam or chemical pre-treatment cleaning are recommended. Beware of highly alkaline products (caustic soda) since they attack the material. Usually, surface conditioners are used for a better surface adhesion of the paint (Wash Primer) although, at present, there are direct-to-metal polyurethanes.

Galvanized steel is pre-treated by the manufacturer with a passivating agent that is naturally eliminated when exposed to weather (six months or more), being necessary in the case of an immediate recoating or in interior surfaces to remove it completely before applying the protective coating Trimas phosphating deoxidant (Desoxidante fosfatizante Trimas), mopping in a single direction. Let it work between 10 to 20 minutes and rinse with warm water. No sanding is recommended to eliminate this pre-passivation layer, as it could damage and eliminate some of the zinc bath protection.

Copper, lead and other less common non-ferrous metals can be cleaned manually or with non-metallic abrasive products. Applying a surface conditioner to improve the mordant and subsequent adhesion is also recommended.

Surfaces must be clean, dry, free of pollutants, mold and mildew. Previous coatings which are not in perfect conditions should be completely eliminated, especially if they are of a different chemical nature. Their removal will be done with chemicals (Remoplast Remover Gel -Removedor Gel Remoplast). Remove any remaining product with solvents or water and detergent.

Sand only in the direction of the wood grains with fine grit sandpaper. Remove dust by mopping with solvent.

The different ways of application of industrial paints are more related to the size and type of surface to be covered, the type of coating selected, the working conditions and the availability of energy than to the inherent advantages of the chosen system. This means that, taking all these variables into account, there is no application system better than the other.

BRUSH: This is a traditional method used when painting small areas or highly complex structures made up of small parts where spray application would generate much waste. A high quality finish is obtained. It is suitable for primers and finishes.

ROLLER: It is used for most decorative finishes, floor coatings, structures, walls, etc. It is not recommended for high thickness coatings because thickness of the applied film is difficult to control with this method. When using this application system, it is advisable to increase the number of coats. Be careful with heavily loaded coatings which can cause sagging or spills, especially in tank interiors where thickness uniformity is important.

CONVENTIONAL SPRAY GUN: It is one of the most commonly used methods for primers, enamels, lacquers and varnishes. It is quick and provides excellent finishes. In most cases, it is necessary to establish a correlation between the air pressure, the viscosity of the paint and the applicator so as to obtain an even film that will not sag and that is free of flaws such as orange peel, low coverage, scratches, drips, etc.

There are high and low performance guns. One of the difficulties of this system is that it requires that the paint be diluted for its application, reducing the final thickness and increasing the necessary number of coats.

AIRLESS GUNS: This system allows the application of all kinds of paints without diluting them or with the minimum necessary dilution. It is more economical than the air spray gun and it is better than the roller in that it is quicker and the paint loss is minimal. It allows the application of highly thick coatings, due to the fact that the paint does not have to be diluted. There are electrical, pneumatic or internal combustion equipments, the latter having greater autonomy and independence. Aided equipment (with some air spraying at the fluid outlet) significantly improves the quality of the final finish. For this system, just as in the case of air spray guns, trained staff is required.
