9 errors when grouting plasterboard

• Mistake 1: Improper surface preparation
• Mistake 2: Using the wrong fillers
• Mistake 3: Poorly adjusted tape
• Error 4: Room temperature too low or too high
• Mistake 5: Humidity too low or too high
• Mistake 6: Lack of care when applying the putty
• Error 7: Incorrectly selected spatula type
• Error 8: No dilatation in the element to be built
• Mistake 9: Improper storage of plasterboard

In this article we have listed the mistakes that are made when filling plasterboard surfaces. You will also learn what to do to avoid filling errors. Thanks to these recommendations, partition walls, suspended ceilings and other building elements made of plasterboard will have a smooth surface without cracks in the board joints.

You can use SINIAT corner tape for joining gypsum boards 12mb or 25mb to join the gypsum boards and ensure an optimal connection without risk of cracking. Siniat corner tape for routing and reinforcing inside and outside corners in plasterboard. Siniat tapes are a modern composite product used in interior design in construction. This gives you a perfect joint surface that is just as effective on a flat surface as it is in corners when joining the ceiling to the wall.

Mistake 1: Improper surface preparation

Solution: Originally finished bevels should be thoroughly dusted off and cut edges moistened with water.

Mistake 2: Using the wrong fillers

Solution: To avoid the risk of using inappropriate materials, use a set of fillers included in the complete drywall system. If reinforcing tape is used for grouting, it is worth using a set of gypsum putty. In both cases, it is necessary to follow the rules for mixing and applying the masses described on the package.

Mistake 3: Poorly adjusted tape

Solution: for filling it is worth using a fiberglass (non-woven) or paper tape. It should be borne in mind that paper tape provides the highest strength of the joint, but its processing is somewhat more time-consuming - it must be moistened before application. Working with her takes a little practice.

Error 4: Room temperature too low or too high

Solution: The minimum temperature at which the putty can be started is +10 degrees C. Until the putty is completely dry, the temperature in the room must be stable and not fluctuate sharply. In winter, it is advisable to fill the gaps with the building's target heating.

Mistake 5: Humidity too low or too high

Solution: Plastering should be done after the completion of other wet work (plaster, screed, etc.). Rapid changes in indoor humidity while the putty is drying out is one of the most common causes of cracks.

Mistake 6: Lack of care when applying the putty

Solution: Carefully fill the joint with filler using a steel trowel. The mass should be applied to the joint with transverse trowel movements in order to avoid cavities under the thin layer of plaster. Each subsequent layer can be applied after the previous one is bonded. The information on the packaging of the filler must be observed precisely.

Error 7: Incorrectly selected spatula type

Solution: In most cases, the satisfactory surface quality is achieved by the so-called "standard spatula", ie only the longitudinal and transverse joints between plasterboard panels.

Error 8: No dilatation in the element to be built

Solution: every 15 m should be made dilatation of the plasterboard surface from which the partition or false ceiling is constructed. In the case of skeleton structures, this stretching must take place every 10 m.

Mistake 9: Improper storage of plasterboard

Solution: Laying wet drywall is a common cause of cracked joints and other drywall problems. To avoid this, plasterboard must be stored indoors, especially in autumn and winter. The recommended duration of the "quarantine" is at least 48 hours before installation. Plasterboard should be placed horizontally every 35cm on a pallet or wooden spacers.
