Waterproofing liquid glass - technology for all surfaces

Industry produces several varieties of these products.But the most widely used, especially in the construction, received a potassium or sodium silicate, water (alkaline) solutions which are called liquid glass (LGL).This material is used for different purposes, but we will focus on only one type of work - waterproofing, ieProtection of structures from the effects of liquids.

In principle, in order to equip a waterproofing layer, there are many different products.Mastic, roll, film and several others.They all have their own characteristics and specifics of the application.But the technique of working with "liquid" glass is so simple that it does not present any difficulty, even for an inexperienced person, does not require special preparation, and use of these products can be in almost any conditions.

Benefits "liquid" glass

First , if necessary to provide additional protection for the construction of metallic elements from corrosion, the ZS - great.It is absolutely not pass not only water, but also air.

Second , LGL is well used to improve moisture repellent properties of various construction and finishing materials.For reliable waterproofing can be achieved not only arrangement of the protective coating.If a little "liquid" glass add-prepare the solution for concrete or plaster, the moisture resistance of the final 'product' will increase dramatically.

Third , if you want to improve the reliability of structural elements, without JS also can not do.It "glues" the individual particles of the material, thereby making the structure stronger.

Fourth , some waterproofing materials have limitations in application.Especially often faced with difficulties when it is necessary to process stations or with a complex configuration, or with a lot of technological openings (passage pipework, vents, etc.).There are situations that due to the limited space to work with rolled products difficult or impossible.

Fifth , not all of waterproofing materials capable of long time withstand a shock, temperature changes and other factors.Therefore, the "liquid" should be used in glass processing, such as septic rings (w / w), the walls of sumps, caissons and the like.

Sixth , in the presence of many small cracks on the surface of the sealant JS simultaneously perform the function of reliably isolating all such defects.

Surface preparation

Such work is often limited to the cleaning of dirt, removal of various elements of the fasteners (nails, screws, and so on) and leveling.Incidentally, when the latter is necessary, depending on the method of exterior trim.

But this is not entirely true, since the activities to be carried out more.Please note that after the completion of all work Wall (floor, ceiling) will be "closed" by the free access.Therefore, care must be taken to maximize the life of the base material.How it's done?

• After cleaning the surface to wash, to expose all defects.In particular, open seams, cracks and the like.Their sealing is necessary in order to reduce heat loss from the room and further protect it against the penetration of liquids.Additionally, bases such careful preparation cleans the pores of its material from dirt, allowing deeper penetration into the structure LGL.
• To prevent dampness and its "satellites" (mold and mildew), it is advisable to make the surface impregnation antiseptic composition.When it comes to finishing construction elements made of wood, make sure you - and flame retardants (against fire) - more on that here.

Then - depending on the method further lining.Among the ongoing activities include:

• applying putty.Done to the maximum level the substrate (eg, a painting);
• priming.To ensure the quality "coupling" between the treated surface and the glued material (eg, Penoplex plates for thermal insulation).

JS Waterproofing can be done in different ways.Let us briefly examine each type.

Obmazochnaya

can be used as a primary or secondary (under rolled products if needed).Not always works with this kind can be used for bitumen production (including pastes).Therefore, based on pre-treated with a solution of "liquid" glass.It is applied in a thin layer, and the crystals fill all the pores of the material, securely sealing them.After that, the pasting roll products.

Depending on the specific structures can sometimes be limited and one daubing.There were no complications and the least amount of time.To better protect the surface layers are applied twice;the second - after first drying.

Penetrating

It is advisable to apply in different emergency situations.For example, the depressurization suture leakage and so on.For sealing damaged places preparing mortar.First water (10 parts) was added 1 part of "liquid" glass, stirred, and then - a portion of cement.Again, "kneading" - and the damaged area, which should be slightly wet before that (if necessary).It is more convenient to use a spatula, which is aligned and "patch".

must work quickly, as the mixture will be almost immediately "catches".That is why it is recommended to prepare the composition in small portions, and only after the completion of preparatory activities:

• clean the injury site;
• expansion cracks.Sometimes this is done to ensure deeper penetration into the LGL material.

Given that the solution quickly hardens, it can not be constantly stirred.This will lead to the destruction of the crystals that are formed fairly quickly.

Often JS is used as an additive.For example, during the preparation of "liquid" Glass concrete mix is ​​introduced together with water added to the mixture.This is often done in the regeneration of the monolithic bases, manufacture of products of w / b, pouring floors and the like.

information is more than enough to decide whether or not to work with such material as "liquid" glass.Incidentally, this method of sealing constructions experts attribute to budget as cost compared with other methods are small, including timing and handling.

cost depends on the type of product, but an average of 10 liters of JS will cost 375 rubles.

Given that such products on the market provides a lot of Manufacturers, you must first follow their recommendations for use.
