How to wall putty

Selection of materials for interior differs significantly from selection for facade work. On the facade, above all, important resistance to weathering. In the interior premises is not as important light resistance and water resistance (except for bathrooms and toilets), but are mechanical strength, good sanding and, most importantly, environmental friendliness, especially when it comes to accommodation. Let's start with the selection of fillings. Now quite widely used oil-based putty adhesive varnish. They are cheap and easy to use. In all other solid disadvantages: environmental insecurity, fragility, poor mechanical strength and poor compatibility with all other materials except for oil-based paints and varnishes. So that the oil-adhesive putty - is an unfortunate choice of material, particularly on the facade. Now appeared on the market a wide range of dry fillers on cement or gypsum. This version is much better than with oil-adhesive putty, but it has its disadvantages. First, these fillers are semi-product, they need to pour in some capacity, very thoroughly, adding water, which is very difficult to do without special equipment. Secondly, the dry filler have a limited shelf life after dilution with water. If you have completed the repair and coating remains, it is money thrown away. These arguments are not so significant at first glance, are seriously undermining the market for dry mixes in developed countries. All these drawbacks are not inherent prepared materials based on aqueous dispersions. You can not fear for his health - links to the putty is an environmentally safe aqueous dispersion of polymer. If your material is well open a bank or in a plastic bag, you can always break repair in a few days without worrying that the return to a piece of stone blocks instead of putty. Of course, it is best to use acrylic sealers, they are more water resistant and durable. But for domestic work should be fine and cheaper based on PVA, in any case, if your house is not flooding. On the facade needed special acrylic coating. It is better not to save, or after the autumn rains your facade can be a big problem. But before the putty, you need to make sure as a wall surface. If it is dusty or flaking, then you need to clean off the dangerous fragments, and then cover with soil firming. Previously used for this purpose PVA glue diluted with water and it's not a bug, but now there are more sophisticated specialized acrylic materials: penetrating, strengthening and antiseptic primers. How correctly parse the filler the stores counter or at a wholesale warehouse? First, you must understand that you need more than one material, and the whole system, ie primer, putty, putty and paint finish. Secondly, it is better to buy everything in one place and from one manufacturer, otherwise there is a chance to buy incompatible materials, and in the case of buying faulty goods will be easier to file a claim. Third, read the instructions carefully to avoid misuse or improper use of the material. Pay attention to the type of filler: malousadochnaya, sredneusadochnaya, coarse, fine, finish, for any materials, water-resistant or nevodostoykaya and soizmerte your needs. Must see is listed on the label number of the hygienic certificate, number of TU or guests according to which the product is produced. Ask the seller to find a copy of the certificate, it is possible there are restrictions for use, not mentioned in the label. Fourth, you should carefully consult with the seller, and even better on the phone with the manufacturer, especially when it comes to unusual and complex works. At the same time you test the level of the manufacturer. Do small firms typically narrow range, and give their coordinates, they do not like. We are always serious plant its exact coordinates, or his representative in the region. Perhaps the manufacturer has a perfect material for your application, which currently do not have the seller. Fifthly, do not buy stuff from the "phenomenal" universality. Good versatile material will always play a good specialist in any particular case, and the price you will pay significantly higher for unnecessary features. Of course, this information does not replace the professional skills and knowledge on the construction business, but we do not set such a task, but just want you to work with good materials.
