Features of using cement-bonded particle boards for the facade
You should think about the following advice to ensure a proper installation:
- Although all the work can be done with your own hands, due to the significant weight of the panels, difficulties in transportation and fitting may arise, so it is advisable to involve an assistant. But if you have to install the products alone, then the parts are cut to a smaller size.
- Slabs with a thickness of 12 to 20 mm are used for cladding. They are strong enough and can better withstand any environmental impacts.
- The technology assumes that the panels will be laid on the frame. The facade must be ventilated, so a counter-lattice is installed in advance, especially if it is planned to insulate the building.
- An important point is the extreme flatness of the base. The fact is that cement-bonded particleboard materials have low bending strength. Curvatures can lead to the appearance of internal stress, which will cause cracks.
- Galvanized screws are used for installing CSP. For them, holes are pre-drilled, which should be slightly larger to prevent butt-mounting.
- The instructions for cladding assume that a compensation gap will be set between the boards. It is necessary to prevent deformation during thermal expansion and shrinkage of a private or country house.
- Panels are sanded and unsanded. The first type is more expensive, but is completely ready for painting, and the second requires laying plaster.
- The resulting joints are sealed with polymer elastic putty or regular sealant. If a large-scale finishing is expected, then reinforcing tape is additionally used. An interesting solution is the use of overlays, which is especially important for the half-timbered style.
Although the existence of so many features may be concerning, it can be attributed to the DSP facade’s recent relatively recent finishing.
Note: The sheets can be fastened together with a strip or special aluminum profile positioned in the space between the two edges.
Installation technology
The material has a significant weight disadvantage, so the foundation’s condition is evaluated before any work is done. It is reinforced further if needed. It is advised to set the basement area apart from the facade cladding’s overall background.
Lathing installation and insulation
Timber or profiles are used to create the frame; the technique chosen depends on the particulars of the case. The first kind is better suited for log homes, while the second is better for surfaces like brick, concrete, or others.
Wooden structure
The process starts with the racks being prepared; they are coated with unique fire and rot-resistant substances.
The following arrangement of the parts needs to be fastened:
- The frame elements are dried, the surface is marked. To do this, the optimal step for placing parts is determined, the standard value is 50–60 cm. This distance allows you to lay thermal insulation.
- The posts are drilled out at intervals of 35–45 cm. The greater the weight of the slab, the smaller the indentation. This technology is appropriate when using self-tapping screws, this will avoid cracking.
- If the base is not wooden, then the holes are transferred to the installation lines. Places for dowels are being formed.
- A thrust board will give additional rigidity: it is leveled and mounted on top of the base. If required, a vapor barrier is pre-laid.
- The racks must be mounted exactly level, starting from the corners. Next, a cord is pulled between the elements, along which the remaining parts are placed. If a gap occurs, spacers are used.
- Mineral wool is placed in the cells, and the structure is sheathed with wind protection around the perimeter. Slats are stuffed on top of the parts for an air gap.
- The resulting pie will provide the necessary comfort in the house.
Metal lathing
The way that such a frame is installed differs slightly:
- The foundation is prepared, marking is done.
- Suspended brackets are placed along the existing lines and fixed with screws and dowels at intervals of 35–45 cm.
- Insulation rows are laid. This can be penoplex or stone wool. The material is pricked onto the structural elements and additionally attached to the walls.
- Wind protection is laid.
- The outermost posts are attached first, and a plane is formed along them.
The method’s convenience comes from not having to build a counter-lattice because the thermal insulation isn’t installed flush with the outside surface.
Fastening the panels
The slabs are first cut to the proper size in order to finish the house’s cladding. A grinder fitted with a concrete attachment is used for these tasks. Drilling is done based on where the frame components are located.
- The facade material is transferred with holding at the edges with a slight slope. This will allow you to immediately install the element in place.
- A lath is laid along the upper section of the base. It should have the thickness of the required gap.
- The fragment is put in place according to the level and baited. It is necessary to check the accuracy of the location, and then finally fix it.
- The following parts are mounted in compliance with the size of the joint.
The window opening receives special attention, with extra frame elements added below, above, and around the edge.
Sealing of seams
Although the low level of moisture absorption of CSP is an undeniable advantage, its penetration inside is threatened by every open seam.
Using an even sealant application is the simplest method of joint design. A construction gun is needed because the composition comes packaged in tubes. This choice is especially important if molding will be installed in the area. The truth is that with time, even the most elastic material will develop cracks in areas where it comes into contact with the slab.
Applying polymer putty is a more stable technique that will make finishing the damaged area much simpler in the event that repairs are needed. If the base is to be plastered, reinforcing tape can be placed on top of the sealed and primed seam.
A good solution is chosen according to the design characteristics.
Additionally sealed are the fixation points, particularly if painting is intended for the surface.
Finishing
It is preferable to use CSP slabs as a final coating even though they can have a decorative role of their own on the facade. There are several materials that can be used to cover the resultant surface; painting is the simplest option. Any kind of composition works well for this.
- The base is cleaned of all superfluous, putty laying places are grinded.
- Priming is carried out. You can use concrete contact. Although many claim good adhesion of such walls, problems can arise, so it is better to apply two layers, waiting for each to dry.
- Painting is done with a roller or sprayer, brushes are used for complex areas. The mixture is laid evenly until the desired result is obtained.
If the joint moldings are contrasting and the main external areas are made in a single shade, this will create a very nice decorative effect. They can be bought already made or painted.
