The cost of the paint facade emulsion. Pros and cons of water-based paint for facades. Aqueous emulsion ink for outdoor use.

In the absence of organic components and organic solvents, silicate paints are non-combustible, fireproof. Acrylic paints: Water-based coatings with easy application, depending on the qualities, to varying degrees resist washing, abrasion and color changes. They are very impervious to water and moderately permeable to water vapor. Our paintings, and, are part of the family of acrylic paintings. Stick well to the surface of a wide variety of properly prepared materials: concrete, cement, wood, masonry, metals and some plastics.

Being flexible, they can expand and contract without cracks or cracks, resisting climate change and behaving effectively in conditions of temperature fluctuations. Acrylic paints dry quickly, which allows you to apply a second coat without a long wait. They do not emit strong odors, are easy to maintain and facilitate touch. Siloxane paints: Paints reinforced with siloxanes, for example, have the properties provided by silicone resins as absorbent vapor but not water, achieving good transpiration and impermeability.

They are characterized by high strength, weather resistance and very good flaws. They are very suitable for the restoration of old buildings, although they are also often used in interior decoration. Waterproofing paint based on vinyl copolymers in aqueous dispersion for exterior and interior decoration, smooth finish. It can be applied to asbestos cement, cement mortar, plaster and plaster before the corresponding primer. Ideal paint for plastering cement mortar, visible concrete, natural or artificial stone, etc. Which are directly exposed to the sun. Waterproof, washable and resistant to elements. Ideal for facades, patios, partitions, etc. easy to apply and extremely effective. It is used on mortar or concrete surfaces. The color is white, for others.

• It also has the property of being fungicide, antimob, antialga and antimusgo.
• Color white, other colors on request.

What is the practical difference between this and the offer of painting for the facades that Esaval offers? The difference between the inner and outer colors is that the exterior paints must be more resistant to weather conditions, which entails a specific relationship and type of components to satisfy each of these properties.

Some paintings are sold as interior-exterior, because they serve us for both applications, although it is always advisable to use a specific painting for the facades in appearance, since by default they assume some of the functions discussed above as essential.

On the other hand, a painting with an external expression may offer some of the functions, but not with the details or specialty that the painting of facades offers. Regardless of price What is the practical difference between the two and what specific features will be recommended? The difference between this or that type of facade painting system is basically the resin that we use in the formula. Each of them gives painting various properties, for example.

Plyolite paint is made up with acrylic resin on a solvent that does not form a film, which allows us to work in very adverse conditions of use. Silicate paint is formulated with a non-filter containing potassium silicate binder and reacts directly with the carrier so that they are especially permeable to water vapor. They are usually used in old buildings, historical monuments, and in general when mineral decoration and high sweat are required.

Siloxane paint has a silicone base binder. This type of resin provides high water resistance, water resistance and high permeability to water vapor. In Peru, it is very common to use plasters and talcum in the repair of facades. Do you think this is a viable and reliable practice?

Usually, restoration facings or cement mortars should be used on facades, since plaster or tempering, or reinforced with sealants, are not a product with good water resistance. That is still a great curiosity for us, since most of the manufacturers of paintings in Peru disclose in their technical sheet that wall painting requires this one to be free of dust, something that with a temple or plaster can never get.

Knowing that here, according to use and customs, smooth finishes are used. This will restore the facades, eliminating these basic elements of the temple, since the cement mortar does not have good adhesion to the plaster and its derivatives. The color resistance to the weather depends on.

Resin Type Used Resin Percentage in the Formula Pigment Type Percentage of pigment in the formula. The type and amount of resin is just as important as the type and amount of dye. Why, in your opinion, is the quality in paint coatings not evaluated in Peru?

We believe that this is a lack of knowledge and a lack of professional knowledge in this sector. Lime is calcium oxide. A substance that, in combination with carbon dioxide, forms stone and marble and, in combination with sulfuric acid, forms gypsum. Air and hydraulic lime, quicklime, anhydrous lime, lime, hydrated lime, hydrated lime.

To facilitate adhesion, apply a thin, diluted lime coat on all surfaces. Then wash the surface to be treated with a brush and immediately apply the paste as if it were made of cement. then smooth the filter.

Cement should not be added to the mass, and the surface should not be marked with it; this mortar can be used in conjunction with bricks, but also serves to make walls, walls, plaster, patches, etc. it simply does not fit into structural beams; One of the advantages of the mortar is that the mixture, after drying, can be reactivated with water, so the mass is always reused without loss. When using lime for compaction and restoration of old plasters, choose hydraulic lime that is stronger and more stable. Then a chess powder or natural pigment is added to the tone.

In the past, milk was used as a fixative; there are those who use white glue, but this makes the paint water resistant, causing it to lose sweat; some still add a little oil that is incompatible with water, but this recipe only works as an emulsion, which is much harder to do.

Bring this compound over low heat, always stirring until completely dissolved and losing its milky appearance. The result is a transparent glue, not too thin, which must be added to the mixture of lime and pigment. Lime paint is not easy to apply, it requires the brush to be applied in a stretched manner using force, and two layers are given, the first of which is horizontal and the second vertical, after the previous one is dried.

Lime paint does not allow retouching; if there is a defect or stain, the entire fabric must be drawn again; before use, the mixture should be mixed; Dark spots and microorganisms can appear in places where water accumulates from constant runoff. In these areas, fungicide should be used: thymol 5% diluted with ethyl alcohol; Preserved ink tends to brighten with time because lime burns pigment. Wear a mask and gloves, because the procedure is acrid and loose smoke; use resistant drums, because at the beginning of the process it instantly warms up and corrodes plastics; mix the mixture every day because sedimentation occurs; always add some water to maintain liquidity. Surface preparation: “Pre-grinding towards wooden shafts gives better results.”

The surface to be treated must be clean, dry, undamaged, free of grease, oils, fats, loose particles and mold. The use of pullers or restorers is not indicated, as well as the previous use of insulating varnish. Wood should have a relative humidity below 20%.

Application: The product is ready to use. The strokes should be long, parallel and in the direction of the shafts. Do not leave excesses and do not load too many coats. Avoid direct sunlight, rainy days, on hot surfaces or with intense air currents. Do not use if rain is expected within 24 hours. Mix well before and during use. On hot days, when they are exposed to the sun, the product often needs to be homogenized. If you form a film or crust on the surface, remove them before applying the product.

For decks, it is recommended to apply the product on six wood surfaces and round ends and edges to ensure uniformity of the film. When using the product, flush the appliance with water. The product has ultra-fast drying, and care must be taken as it does not interrupt the use in the same product, for example, as it may cover the surface coating. If this happens, localized grinding is displayed to minimize the possible mark.

Drying: The approximate drying time by touch is 30 minutes, and between the layers - three hours. General healing occurs in three days. Repeated use: Repeated use is recommended in early visual evidence of superficial aggression. Surfaces should be cleaned or washed with mild soap and water.
