Installation of metal frame for the arch of the drywall

Cut rails metal profiles desired length and attach them to the wall.You need to cut the two profiles across the width of the opening and fasten them at the top.On both sides of the opening is also installed on the two profiles, but their size will depend on the range before you cut the arch of the gypsum board, see photo below.If you commit a frame of metal profiles on a concrete wall, you must use the drill to drill holes, set anchors, and then tighten the screws.

If you plan to attach metal profiles to wooden wall, use screws of at least 40-50 mm.The distance between the screws should be about 10-12 cm.

Mounting Profile
Fixing the metal frame to the wall.

After fixing metal profiles to the wall, you can continue the process of setting the first sheet of drywall.To perform this operation professionally, use an electric screwdriver with torque control.Plasterboard thickness 12.5 mm, we recommend that you use screws 3.5h35, and for drywall thickness 9.5 mm is suitable screws and smaller.

Fastening drywall

Similarly obsheyte plasterboard other side of the frame.Using a screwdriver, screw the screws so that their caps are flush with the surface of the gypsum board, otherwise you'll have to close up filler recess.

Tip: To secure the drywall on a metal frame, screw the screws every 15 cm.

Fixing the sheet with the other hand

next phase of work - fixing a bent metal profile on the edge of plasterboard arches to increase rigidity.

Measure the length of the arc and cut the appropriate section of the profile with scissors for metal.Do not forget to use protective gloves to avoid cutting hands on the sharp metal edges.

Tip: To bend the metal profile, just make incisions on his side faces every 10-12 cm. These cuts will allow to give a curved profile.If you need to bend the profile is stronger, just make more cuts.

Remember that the frame is not completed, unless you set the profile perpendicular to the segments that need to link the side walls of the arch together.These binders jumpers must be placed at several points.

Mounting wooden frame for the arch of the drywall

Make a wooden frame for your plasterboard arches too easy.True to this, you still need plywood and wooden blocks.Measure the width of the door opening, subtract the thickness of the drywall and plywood, and you get the thickness you required wooden bars.Draw on plywood arc arch and drank it with a jigsaw.

Frame for arches

Using 5-cm screws, secure the plywood on wooden bars, performing the function of the frame arches.Then secure the arch in the doorway with long screws, screwed every 15 cm.

last step is to mount the second plywood wall paneling and plywood drywall.The latter must be fixed using screws drywall.

Install arc arch fragment

Once you have created the framework and set the side walls of the arch, it is necessary to fix the lower arcuate section.

With a tape measure the width and length of the arc.Using a knife and square, cut a piece of drywall in accordance with the received size.

Now use a little trick that will help make the drywall flexible.Every 10 cm is applied to one side of the rectangle parallel Papier Mache notches, notched knife paper layer.It is important to use a construction wherein the level or angle to perpendicular cuts have turned lateral edge of the sheet and parallel to each other.Be patient and take your time to avoid mistakes.We reiterate the need to comply with security measures.

Make sure the treated area is not your scraps of paper or bits of plaster, as they can, mixed with a filler, worsen the appearance of the surface.

Application of putty with a simple spatula
Application putty with a spatula.

Using a spatula, apply makeup on the cap screws.Remember that you should put enough putty to create a perfectly flat surface.

Cover caps screws with putty.

If there are any minor surface defects drywall (dents, holes), simply fill them with putty, and then with a spatula or grouting, remove excess material and smooth the bumps.Do not forget to make sure that the screed surface is flush with the rest of the walls and arches, as would later be difficult to correct these errors.

Tip: Go trowel float on the curved surface several times until the line does not become her perfect smooth.

application of drywall joint fillings on the wall.

Shpatlevanie When you are finished and satisfied with the result, you can go to the next step - pasting of joints and edges of the drywall to hide irregularities, giving strength gypsum and prevent cracking.There are two alternative material designed for this purpose - a special paper tape and fiberglass mesh.You can choose any of them - both of them are good enough.We are in the project used the fiberglass mesh.

Bonding serpyanka

Measure and cut a piece of mesh required length.Then place the mesh or paper in the center of the joint and gently press it with your fingers or a spatula fresh putty.Pay close attention to the grid during installation it is taut, otherwise it will fold.It was not clear moments?
