Direct contact with liquids adversely affects any materials - this is an axiom. Therefore, in the sphere of construction( repair, restoration), the quality waterproofing of all the structural elements of the "object" is one of the most important technological stages. The market is filled with various types of products, which can be used as a protection against moisture.
Not so long ago the tendency of aspiration of our fellow citizens to the choice of "goods" from the domestic producer was clearly indicated. The reasons are simple - many "our" materials for waterproofing on the quality of imported practically do not differ, but importantly - are much cheaper.
In this article we will consider the products for waterproofing under the brand name "Water"( WaterStop).In a short time, these waterproofing compounds managed to gain prestige both among professional builders and private developers.
Brand "Glims"
What is it? The basis of these dry mixes is cement. Solutions( gray) can be used for finishing surfaces both inside and outside the premises."Glyms" is something between the plaster and the lubricating waterproofing, since the layer after hardening acquires sufficient rigidity.
Product features
-
elastic modulus is low, therefore, to cover elements subjected to dynamic loads, should be used with caution; - increased adhesion "Glims" allows you to protect any foundation, regardless of its material( stone, reinforced concrete, brick);
- resistance to aggressive substances and low temperatures. Can be used in the range from -55 to +70 ºС;
- high strength of the applied layer( for compression) - 80 kgf / cm²( after final drying);
- technology of work allows you to finish not only a dry, but a wet basis;withstands hydrostatic head: direct pressure - 7, return - 2( atm).
Consider the specifics of the application of this material:
Preparation of the
base For better coupling to waterproofing, after the surface is "cleaned", it is primed. For dry it is recommended to use the composition "Glims®Grunt", for wet - "Glimsy® Hydrobond"( the dry mixture is rubbed into the base).
Preparation of
solution For better mixing and elimination of lump formation, it is desirable to use a mixer. By the way, it costs about 185 rubles.
You can also make a nozzle for an electric drill from a thick wire( for example, a "butterfly").
Surface finish
Composition applied by spatula or brush. This is done in several approaches: the first layer( no more than 1.5 mm) - after drying( about 24 hours) the second - after 24 hours( if necessary) the third. The laying of each next layer is made perpendicular to the previous one.
At the time of production, the temperature indoors or outdoors should not be below +5 ° C.When finishing the buried parts of structures( foundations), reservoirs( pools) and the like, the minimum number of layers of waterproofing is 3.
The shelf life of the product is no more than a year.
Price
In the sale of "WaterStop Glims" comes in bags of 20 kg( from 790 rubles) or buckets of plastic for 4 kg( from 245 rubles).
Brand "Ivsil"
What is it? The difference from the mixture of "Glyms" is that there are polymer additives in the composition. Therefore, this brand belongs to the category of "waterproofing coating".The main characteristics are similar to the material described above, so it's worth mentioning only some differences.
The
-
product features some layer elasticity, which makes it possible to produce waterproofing in places where there is a risk of deformation of the substrate. For example, for sealing joints( seams), which can "walk" at temperature jumps; - is great for processing already plastered surfaces and screeds;
- the basis intended for stacking of a mix "Ивсил", should be rigid enough.
Application Specifics
The substrate must be moistened before starting work. The peculiarity of the finish is that the next layer is laid "on wet".In other words, drying does not need to wait for the previous one, and this significantly shortens the time for waterproofing. But further finishing is possible not earlier than in a day or two( depends on the air temperature and the quality of ventilation in the place of work).
Shelf life "WaterStop Ivsil" - no more than half a year.
Price
- 20 kg( in paper packaging) from 510 rubles;
- 5 kg( bag) - from 155 rubles.
