Technology of restoration of elements of lesser architectural forms

   Severe climatic conditions of our region lessen the life of lesser architectural forms greatly. That is why realisation of modern projects of city improvement is senseless if do not take into account the costs of service, repairement and replacement of disabled elements.
   Jperation life of city furniture is limited by the operation life of the most short-lived elements. They are wooden elements of sofas, benches, litter bins. They shrink and cover with cracks aas time goes. We use the most durable wood — larch, special varnishes and steeps that can help make the life of elements longer. Production technology makes it possible for wooden elements to operate without extra processing for 3-5 years.

   Restoration and replacement of disabled elements can be performed according to one of the following shemes:

• without replacement of restorated lesser architectural forms — city furniture is brought away from the installation place by parts, necessary works are done, after that LAF are brought back;
• with partial replacement of the restorated lesser architectural forms — the specified party of LAF (7-10 articles) is brought away, instead new purchased city furniture is installed; as the restoration of the first party is finished the second party is formed, instead of the articles of the second party LAF from the first party are installed; this scheme means acquirement of an extra party of articles;
• with total replacement — instead of the restorated articles on the whole area of improvement new purchased LAF are installed; restorated articles pass through a total processing cycle and then are installed in another place; this scheme means acquirement of a party of articlesof the same volume as the restorated one.

   The cost of restoration works depends on the degree of the LAF and the chosen scheme of restoration.

Types of works performed:

Kind of material	Type of works	Technologies used
Wood (larch, pine, birch)	1. Grinding all surfaces are ground including ends and bevels with abrasives for wood	soft sorts (pine, birch) — abrasive up to «150» hard sorts (larch) — abrasive up to «180»
	2. Filling deep cracks are filled , shallow cracks are puttied	filling for wood
	3. Painting water-base paint-and-laquer materials are used for outdoor works. Painting is performed as follows: water-soluble protective steep (colour according to sample) intermediate water-soluble priming or self-priming water-soluble thixotropic varnish (after intermediate priming make obligatory grinding — pile removal) water-soluble thixotropic varnish	paint-and-laquer materials for outdoor works by SayerLack, Renner
Metal	1. Cleaning metal elements are cleaned either on the place of LAF installation, or in stock	—
	2. Replacement fastening elements are replaced (screw-bolts, nuts), they are smeared, if necessary separate parts of frame or the whole frame is replaced	—
Stone elements	1. Cleaning sides of chairs, litter bins and benches are cleaned and washed	—
	2. Replacement broken stone elements are replaced with new, sometimes pastiong of cracks on the surface is possible	—
