Caulking in Toronto

Gypsum plasterboard is one of the most popular building materials to date. Due to the availability, simplicity and convenience of working with it, gypsum plasterboard is used for finishing walls, ceilings, slopes, arches, creating the author's design of the premises.

This material consists of two sheets of cardboard with a layer of gypsum between them. Plasterboard is produced in the form of slabs or sheets of different thickness. After their installation, it is necessary to additionally process the joints of neighboring sheets. This makes it possible to achieve a strong connection between the two panels and to obtain a homogeneous and even surface over the entire area of the room.

Caulking in Ontario. Where to start?

Let's consider the existing methods of caulking in Ontario. Depending on what kind of puttying is used, joints processing is applied either with use of reinforcing tape, or without it.

Surface preparation

In any case, the surface must first be prepared before machining:

  • On the edges of the joint of both boards, use tools (planer or knife) to make chamfers at an angle of 45°.
  • Make sure that the boards are installed properly: they must be in the same plane and the screws are slightly recessed in the board.
  • Remove dust and gypsum particles from the joint.
  • Preparation of putty mix

    Application of the first coat of putty

    After preparing the mixture, you can start applying the first coat of putty. To do this, distribute the previously prepared mixture in the direction perpendicular to the line connecting the two boards. In doing so, we try to press the mixture deep into the joint and carefully fill the entire gap. Then, it is necessary to smooth out the putty in one continuous motion along the entire seam.

    These operations are common to joint processing, regardless of whether the reinforcement tape is planned to be used or not.

    Caulking in Toronto with metal ribbon

    There are only three kinds of ribbons:

  • paper tape;
  • fiberglass tape;
  • self-adhesive fiberglass mesh tape.
  • Caulking in Toronto with paper tape

    When using paper tape for sealing seams, the highest possible joint strength is achieved. However, its use is limited by the requirements for fire and moisture resistance of structures. In such rooms paper tape is not used.

    After applying the first coat of filler mortar for joints with paper tape, we do the following:

  • We measure the required length of the tape and soak it in clean water.
  • After soaking the tape, press it into the previously applied layer of putty. In doing so, avoid any air residue under the paper tape.
  • Then squeeze the rest of the putty out from under the belt and cover its surface with a new layer of mixture of small thickness. Then wait for the joint to dry.
  • After that, put a layer of mixture again, but already 50-60 mm wider than the previous layer and wait for it to dry again.
  • For the final design of the seam, we apply the last layer of putty, it should be 60-80 mm wider than the previous one. The width of the resulting layer should be at least 400 mm.
  • After hardening of the last layer of putty, it is necessary to do the grout and grinding of the seam to align it with the gypsum plasterboard slabs.
