The main features of outdoor water panels make it quite possible to use cement slabs for the facade. But it is all the more relevant to study the installation of facade slabs on the walls of a country house. Another important topic is how they differ from internal slabs.

What it is?

Describing outdoor water panels for the facade of a country house, it is necessary to indicate that it is one of the types of sheet-type composite materials … This is a logical development of the idea of a drywall sheet, only much more technically advanced. The cement board is supplemented with a double-sided reinforcing mesh. As a result, it is possible to achieve increased mechanical strength. An important advantage of such products can be considered their low susceptibility to moisture - even damp blocks remain quite reliable.

It is clear that this property allows the slabs to be used not only for facade work, but also for finishing wet rooms, such as bathrooms or swimming pools. Although this is already a side effect, it is not particularly important.

Installing water panels is no more difficult than many other sheet materials, and according to a number of builders, even easier.

Speaking about the differences from the internal model, it is necessary to understand that the main difference is related to the peculiarities of the composition and practical properties. The external versions are much stiffer and less bendable, so it is impossible to accurately fit them to any substrate shape.

Internal versions are more flexible . They are easier to bend and thereby adapt to any curved radius. And therefore, the interchangeability of such structures is further limited. A typical outdoor water panel is a reinforced mineral slab. Inside there is a light mineral filler, and outside there are reinforcing elements.

Characteristics and properties

Outdoor water panels are absolutely resistant to mold and mildew. They have the same strength as similar layers of concrete and brick. Under severe chemical attack, the structure retains its basic characteristics. The product differs, of course, in impact resistance and is not subject to deformation. Other important points:

• slabs are usually made of high quality Portland cement;
• special shockproof edges are formed on both sides of the slab;
• the design is resistant to frost;
• it is not difficult to process the water panel;
• the material is completely environmentally friendly and does not contain toxic impurities.

The width of the blocks can be from 900 to 1200 mm. Their typical lengths are 900, 1200, 2000, 2400 mm. On request, water panels with a width of 2500, 2800 or 3000 mm can be supplied. The thickness is usually 12 mm, or more precisely, 12.5 mm. Other specifications are as follows:

• weight of 1 sq. m. about 16 kg;
• elastic modulus at least 4000 MPa;
• the water panel does not burn;
• the strength of adhesion of the structure to the main layer of plaster is not less than 0.75 MPa;
• the minimum level of natural radioactivity.

Mounting

The technology does not provide for any difficulties. For installation, the use of glue, screws and putty is usually enough. It is best to use branded Knauf accessories for decorating external walls:

• pointed end screws;
• self-tapping screws with a drilled end;
• hardening adhesive solution;
• white putty (this shade is very important).

It is very important to clean the base material properly. Even the smallest contamination can have an extremely negative effect on the performance of the coating.

Another relevant requirement is maintaining the correctness of the calculation vertically and horizontally . Where this requirement is met, high quality work can be guaranteed. The guide profiles are fixed very firmly, because they act as a base for all other parts.

Other recommendations:

• pre-fill the part with sealing tape to increase adhesion;
• the crate must be mounted using the same technology as the gypsum board;
• adjustment of the size of the panels is made with a construction knife;
• you need to revet the wall from below;
• the sheets are shifted by 1 profile rack, otherwise cross-shaped joints may occur;
• panels should be covered with plaster;
• it is imperative to close up all seams and joints, as well as fasteners.

Top manufacturers

In almost all online stores, the only option for water panels is products Knauf … This concern has long established itself from the best side. However, goods of this kind are supplied by Volma , also with a good reputation. It is impossible to meet products of other brands.

They are not sold either in online stores or in large retail outlets and chains selling building materials.
