Changed the lamp, I spent 2 days. I had to plug the ceiling foam

It was on the ceiling, insulated foam inside. After dismantling the old lamp with a mercury lamp it was found that the foam was not under it - everything was done to bypass the lamp box. And so, on a normal ceiling tremendous hole that had to be patched!

The plan is

Since the ceiling is insulated with foam thickness of 30 mmFor repairing bought a new sheet of the same thickness density 30. Still needed:

• foam (minimum volume cylinder);
• starting putty 2kg;
• finishing coat 0.5 kg;
• acrylic paint 1 liter.

Go...

Under resolution uncovered portion cut foam strip and another piece. Further First apply the foam to the foam end rising above the ceiling(Photo 2), Then cut piece (Photo 3) and gently insert it into place.

Stripes tried to press several times for 30 minutes, until the foam grab. This is necessary, as it was at hand foam for bonding and assembly, which increases in volume 1.5-2 times.

The foam has dried, glued foam proshpaklevat starting putty. Reinforcing mesh is not used, because they do not see the need.

It was generally used for thermal insulation of the entire area of ​​the ceiling!

Later trim the frozen layer, caused finishku and left to dry before painting until the morning.

Putty white is better to take to make it easier to paint over, but it can be a different color, then it is necessary to add 1-2 more coats of paint.

Dried putty first trimmed with a spatula, and then a little processed mesh abrasive with a grain size 220 (Picture 4).

Mesh can be used without grinding the board, but this is not so convenient and it is not necessary to press hard to deep scratches were not.

Since the clean room ceiling paint is generally non-yellowing and does not change color, then I take any acrylic waterproof paint on the ceiling and after the dust removal roller is rolled a couple of times. 2-3 hours once again to paint the desired area, and that's it.

On picture 6 shows the result of the restoration portion between the wall and a square lamp. Overall was good, 3 months after the repair of cracks and other changes are not present.
