Cleaning, restoration and staining of suspended ceiling

Suspended ceilings

USPENDED CEILINGS
The purpose of the suspended ceilings, independently of its speed of fitting and its job of hiding unsightly technical installations, is the easy and permanent accessibility to the said installations: electric cabling, heating and air conditioning pipes, information installations.

ORIGIN OF THE PROBLEMS
Suspended ceilings get dirty, are prone to water damage, become impregnated with nicotine and are left with finger marks after work has been carried out.

EXISTING SOLUTIONS
1° - Replace old tiles.
Disadvantages :
a) Removal and disposal of old tiles.
b) Re-assembly of accessories housed in the tiles (sprinklers, spotlights, etc…)
c) Risk of breaking tiles when putting them in place.
d) Metal frame remains dirty.
e) Difficult to find the same type of tiles.
f) Extended shut down of premises

2° Total replacement : tiles + framework
Disadvantages :
a) Cost
b) Obligatory involvement of technicians (electricity, information, heating, air conditioning)
c) Site shut down

3° “Traditional” painting of the suspended ceiling.
Disadvantages :
a) Loss of fire certificate
b) Obvious painted aspect

c) Paint sticks the tiles to the structure
d) Layers of paint create a film which causes the paint flake off as soon as a tile is lifted
e) Acoustic tiles become clogged, causing echoing of sound
f) Ceiling not as bright as it was originally.
g) Risk of tile distortion
h) Old stains appear through the paint.
i) Strong odour.
4° - Cleaning.Cleaning is generally carried out by de-colouring the stain. The most commonly used procedure is micro-spraying with oxygenated products.
Disadvantages :
a) Does not remove all stains.
b) Original colour is refreshed but blurred and lacks uniformity.
c) Not all tiles may be cleaned.

RENOVATION BY BASIC SYSTEM®
Re-colouring by spraying a colour emulsion is far quicker and less costly than replacing the tiles or replacing the whole ceiling.

TECHNICAL ARGUMENTS OF BASIC SYSTEM®
1° - Excellent surface coverage, of both frame and tiles (fibre or metal).

2° - No film-building effect:
a) No clogging of acoustic threads, no echoing of sounds,
b) Tiles do not stick to the frame,
c) The emulsion does not flake off when work is carried out on the suspended ceiling.

3° -Excellent reflector of light.

4° - Acrylic binder in aqueous phase, therefore odourless and quick drying:
a) therefore odourless
b) quick drying.

5° - Uniform colour over whole renovated surface

6° - Fire resistance certification.

7° - Biodegradable product.

8° - Long-lasting results.

9° - Operation may be repeated several times over the years (little excess weight brought about by the projected product).

10° - Quick application, therefore premises not out of use for long. Over the course of one night, three operators can treat 500sqm.

11° - Quick application, no harmful effects. No risk of dirt or spattering thanks to protective sheeting.

12° - No risk of tile distortion.

METHODOLOGY
1° - Masking of all surfaces which do not need re-colouring: lights, sprinklers, vents, walls, floor.

2° - Removal of dust from parts to be re-coloured.

3° - In the case of a very greasy ceiling or one which is impregnated with nicotine, cleaning with a specific grease removal product.

4° - Removal of humidity stains (water damage on acoustic tiles).

5° - Re-colouring by spraying DALFOND®, pigmented emulsion. Re-colouring is generally done in white. But is also available in any color.

6° - Removal of masking.

7° - Inspection.

8° - Cleaning.
