Especially popular among the finishing materials deservedly gypsum board. Not only did he quickly mounted, but does not require a "wet" process, It allows you to create designs and shapes of any complexity.
The only drawback, arising during installation, sealing of joints drywall.
If the sealing drywall seams made with impaired Technology, Over time, the joints cracks. And the question arises, and how to seal the seams in drywall, how to use the tool and related materials.
The procedure works
Caulking drywall seams made on an already assembled from gypsum board constructions, partitions, walls.
But without a properly sized tool, accompanying materials will not be able to perform high-quality work.
Remember! Putty joints plasterboards recommended when the room temperature is higher than + 10ºC and humidity of not less 60%.
For mixing the solution and make better use of the capacity of small volumes.
Remember! Kneading putty mixer solution is recommended to perform at the very low speed. At high speeds a large amount of air is adjudged solution, which increases the porosity of the resulting solution, and therefore, reduces its strength properties. When mixing manually quality mixture obtained above, but the use of the tool increases the efficiency and productivity of work.
For mixing the solution can be used any container, but it is best to use a plastic bucket or trough special. the main thing, capacity to comfortably wash after using the mixture.
Shpatlevanie drywall joints is performed spatulas different widths. The minimum width of the spatula 100 mm. At large areas is desirable to use spatulas width 350 mm.
Stripping putty joints is recommended to use fine sandpaper, sand mesh. Use sand mesh is more convenient, but its cost is much higher sandpaper. Still, you will need building knife.
you need to stock up Primers, deep penetration, filler for gypsum board joints, armored belt.
We have repeatedly pointed out, that you should not skimp on quality materials. Best auxiliary materials during grouting plasterboards are associated items firm Knauf, developed the technology to use sheets of drywall.
Caulking drywall recommended dry putty mix Knauf Uniflot, which is based on gypsum cement with polymer additives or Fyugenfyule.
There are other equally high-quality materials for joints, e.g. putty composition for grouting: Knauf, Uniflott, Fugen, Volma. It is only necessary to always remember, all supporting materials must be from the manufacturer, plasterboard which you bought.
You should not skimp on the quality of finishing materials. Proverb: "Miser pays twice" holds full. Details of choosing the right solution putty for grouting GCR.
The procedure for sealing drywall seams
Surface preparation plaster
Works should begin by cleaning the surface of docking stations.
Strip the solution to cope with the large spatula, Remove dust with a vacuum cleaner. Holding the trowel at an angle of 30º, passes through places of joints of sheets, removing any irregularities.
Screw the cap protruding screws, drowned them 1 mm.
A damp cloth to remove dust from the surface.
We have a factory of gypsum boards and the cutting edge. Factory edge does not require preparation, and here at the cutting edge at the ends it is necessary to chamfer.
Chamfering at the cutting edge is used a special tool, a plane called a flange. It provides a chamfer at the ends of the cutting edge at an angle 22, 5º.
Do not try to get a chamfer using a construction knife.
The presence of the bevel greatly facilitates bookmark filler layer, which increases the strength of the structure.
docking location must be primed. The primer is applied with a roller or brush wide hammers finishing. Application roller improves rubbing process primer, than the use for this purpose brush.
Allow time for the complete drying of the primer. It is better, if you start a day Shpatlevanie.
Cooking putty mix
And what caulk the seams of drywall?
Special putty mixture is prepared strictly according to the instructions, without various improvisations and digressions. Caulking gypsum boards produced special mixture. They come in gray or beige. Color does not affect the quality of the solution.
So what putty repaired drywall joints?
It is preferable to use a mixture of firm Knauf, specially designed for this technology. We recommend the use of dry mixes or Uniflot Fugen Fyuler.
But there are other high-end counterparts, produced by various manufacturers.
Consistency of solution should resemble a thickness not liquid cream.
Remember! Cooking should be as much a solution, how much you will be able to develop over the life of the solution life, this 20 minutes.
Using a spatula mixture is applied uniformly on the joints, spread with a wide spatula. Simultaneously shpaklyuyut cap screws.
The layer of putty on joints with sheared edge thinner layer at the junctions with plant edge.
While wet plaster, at the seams special reinforcing tape is applied and smoothed wide spatula. Glueing increases the reinforcing belt seam strength, does not subsequently formed cracks.
It is recommended to use a reinforcing paper tape Kurt or its analogs. The tape has a high strength and prevents cracking.
Reinforcing tape Kurt perfectly breathable, It does not stretch easily and absorbs moisture. After drying, the tape is not a bubble, It does not cause the appearance of cracks. From analogue tape Kurt recommend
Not recommended for sealing of drywall joints use paper tape. Paper tape is not breathable, It does not absorb moisture. After drying, the paper web is bubbling, raising putty layer.
Well, quite useless self-adhesive mesh tape, so beloved by Russian painters. It is easily stretched and has no strength.
At the finish, a final grouting drywall putty.
The final stage
After drying, a connecting seam is trimmed with a spatula if necessary, trimmed sandpaper. The entire surface is covered with a layer of soil.
You noticed, that jointing plasterboard with their hands is not complicated and can be performed independently at home even novice master.
But to answer the question, how to seal the joints between plasterboard, it is recommended to view a training video.
- to obtain a quality connection node gypsum plasterboard, abutting edges must have a chamfer, factory or use of the planer;
- chamfer must necessarily be missed the mark permeability deep soil;
- as reinforcement recommended paper reinforcing tape Kurt or its analogs;
- as recommended special putty composition for sealing joints plasterboards.
- Video on grouting plasterboard will help to understand the intricacies of the work.
