A simple trick that saves a lot of nerves and time. How to easily level a slope with a perforated corner

How to glue the corners on the slopes?

Today we will seal the window slopes with plastic perforated corners. Corners, as you know, are the most vulnerable point of a window opening, and decor elements will protect them from chips and form an aesthetic appearance.

Corners are plastic and aluminum. I prefer plastic because aluminum oxidizes and darkens over time. Perforation zones are especially susceptible to corrosion. The darkening of aluminum begins to show through a thin layer of putty, which is why the bevel angle becomes gray and untidy over time. And nothing can be done about it. And plastic retains its whiteness for many years.

Preparation for gluing

Before we start gluing the corners, we must first examine the slopes for evenness.

The angle is checked from one side and the other.

A laser beam will also help to check the evenness of the corners, if such a device is available. The beam will more accurately show the degree of obstruction of the slope.

If necessary, the slopes should be leveled with putty.

In the lower part of the window, slopes are damaged more often. Here, too, damage to the corner closer to the window sill is especially noticeable.

Previously, there were no corners, and bevels were formed exclusively with putty or plaster solutions.

These potholes will require a little more putty.

Corner bonding process

After the puttying of the window is completed, the corner is glued to the raw putty. A corner cut in advance along the length of the slope is attached to the corner of the window and slightly pressed. In this case, the putty will appear in the perforation holes.

While the putty is damp, again check the level of the corner for evenness. Then, if you need to add putties, the corner can be slightly bent and the mortar added there.

Now that you have made sure that the corner is installed evenly, you can start filling the perforation with putty.

This filling is performed on one side and the other.

In conclusion, when the putty dries, it remains to lightly sand it with sandpaper to remove its excess.

Do I need to use additional fasteners for the corners?

Some masters recommend using various types of glue for gluing corners:

• liquid Nails,
• ceiling,
• instant adhesive;
• silicone sealant, etc.

I think that for perforated corners, buying glue is an extra waste. Not all brands of glue are able to become colorless or transparent. Most of them show through the putty. In addition, when you put it on liquid putty, it appears in the perforation holes and forms a kind of locks.

I also don't like the idea of ​​nailing the corners with a stapler or air gun. The bracket will not enter a concrete or stone wall, the impact of the chipper will leave a dent on the wall, and the corner itself will be washed.

In the case we have considered, the corners are hidden under the putty. But if you take the outer corners without perforation, then you can use either putty with an adhesive effect or glue that is close to the composition of the plastic. For decorative outside corners, liquid plastic, liquid nails, polyurethane glue or silicone sealant are suitable.
