FIBERGLASS CLOTH REINFORCEMENT FOR WALL AND CEILING IN PLASTERING WORK
Fiberglass cloth is an inexpensive material that does not burn, is elastic, low weight and has good strength. It is impregnated with a solution that gives it resistance to alkali plaster. In recent years, fiberglass is becoming more popular in repair and construction and finishing works.
It has been widely used on facades, ceilings, uneven surfaces and corners;
It can significantly improve the strength and mechanical properties of surfaces be reinforced;
For reinforcing walls and ceilings during the plastering work.
The main advantages:
A: able to withstand high longitudinal and transverse load;
B: have a good grip on the mineral binders mixtures;
C: high resistance to stress corrosion and chemical resistance;
D: easy to install (does not require additional skills);
E: Resistant to high temperatures, temperature range from - 200°C to +550°C and silica fiberglass
fabrics up to +1200 centigrade.
G: High electrical insulation properties
H: Different types of weaves: plain, satin, twill
1m×30m/roll, 1m×50m/roll, 1m×100m/roll, 1m×150m/roll
How to operate fiberglass mesh on the plaster, gypsum wall, drywall, ceilings...
Fiberglass cloth interior mesh for interior with 5mm × 5mm mesh
The base, which is home to plasterwork, must be solid and clean. Remains of old paints, coatings, grease, dust should be removed. Irregularities of more than 20mm should be filled plaster composition. Base with high moisture absorption should be primed.
The application of plaster
The prepared substrate evenly over the entire surface of the plaster is applied notched trowel
Installation and indentation glass cloth mesh
Place the plaster mesh glass cloth on the inner surface in the form of vertical stripes with overlapping webs of at least 10cm, and press into the painting and adhesive mortar with a trowel or spreader . The layer thickness reinforcement should be not less than 3mm
Mounting angle elements
Place the corner pieces on plaster, grid pressed into the plaster with a trowel or spatula
The application of the final layer of plaster.
When completely dry painting and adhesive apply a final coat of plaster
The device of window and door openings.
Window and door openings are reinforced with additional strips of mesh width of 300mm and installed prior to the application of the first reinforcing layer.
Fiberglass mesh facade, exterior plaster reinforced fiberglass fabric 5mm×5mm
Prepare the surface to the reinforcement:
The wall surface having no decorative coatings should be thoroughly washed with water. Old plaster should be checked by tapping the surface, in places hit by the detection of voids and restored. Bumps and drops of more than 1cm should be removed, and the cracks are plastered. Spray coverage should be examined for compatibility with the adhesive composition. Inconsistencies in these structures must be completely remove the old coating. The substrate must be primed with a special compound deep impregnating agent. The primer surface should be done only after the curing and drying, leveling layers.
The base reinforcement layer:
By reinforcing the basic unit of plaster embarking upon curing of the adhesive , the position fixing of insulation, and to achieve strong coupling it with the base, but not earlier than 24 hours after gluing .
Deformation and expansion joints.
The unit building corners of window and door openings.
The corners of window and door openings are reinforced with additional strips of 200 - 300mm mesh size and are installed before applying the base reinforcing layer.
To the unit base reinforcement layer is made extra special corner reinforcement angles nets with plastic PVC profiles.
The base layer in the area of the basement.
In the area of the basement to provide the necessary resistance against the attack on the surface of the insulation is made extra reinforcement armor-clad (vandal proof) fiberglass. After curing, the additional reinforcing layer subsequent operations are performed by conventional techniques
Fiberglass cloth for painting with 2mm × 2mm mesh
Remains of old paints, coatings, grease, dust should be removed. Irregularities of more than 20mm should be filled plaster composition. base with increased water absorption should be primed. Apply to the surface of the putty.
Installation and indentation glass cloth mesh.
Place the fiberglass mesh on the freshly putty composition. Imbedded fiberglass cloth, using a trowel or spreader, evenly covering the entire surface
Applying the finishing layer of putty.
Apply to the surface of the reinforced final layer of putty, sanding the surface primed.
