Overview of Installation Work

(1) General
Installation work accounts for a substantial part of the entire CROWNBOND work. Supposedly. The best installation procedures will be chosen from many aspects
Including quality, construction period and its cost. In this chapter, we would like to look over the basics of installation procedures of CROWNBOND taking a small to medium scale external cladding project as an example
When we install fabricated panels at project site, we implement the installation work in accordance with the drawings and specifications of the project. In the event that we find some discrepancy between drawings and the actual conditions at project site, we have to report to and consult with the project controller

(2) Installation procedures
General installation work consists of the following procedures:

(3) Comments on each procedure
A Unloading
Unload CROWNBOND panels on the roof, on each floor or suitable places on site. The unloaded panels on each floor will be just those required for the relevant floor. Fasten the panels together with rope and a covering sheet for protection.
B Marking
Confirm the reference line in the presence of a superintendent. Mark the installation line, based on the reference line and the approved shop drawing
C. Substructure work
In order to install the substructure, weld steel bracket pieces onto hole-in an chors (Example of bracket: l-50x25x15mmt.weld continuous steel angles onto the brackets. All the angles will be finished with rust inhibiting coating, which conforms to the project standard to prevent fire during welding, pay attention to sparks that drop on the cover sheet and veneer. During the substructure work, check the level with a flush thread and plumb-bob line, or water level, if necessary.
D. Rust inhibiting coating
Apply rust inhibiting paint onto all the welded points including the back and edge. The paint and Coating thickness must conform to the project standard.
Make the installation line in accordance with the shop drawing. Fix CROWNBOND panel onto the substructure with self-tapping screws, 4mm in diameter, after confirming the position of the panel (left, right, top and bottom). The fixing interval will be normally 300-400mm depending on the strength calculation. After confirming the fixed conditions, peel off the protective film and clean the removed film
F. Accessories work
Bring the accessories to the scaffold passage, as indicated in the shop drawing. The
quantity of accessories brought to the scaffold passage must be kept to a minimum to avoid dropping and other accidents. Lay large accessories diagonally on scaffold passage. Mark the installation line onto the substructure to meet the position of the window frame, fix the accessory with self-tapping screws, 4mm in diameter, with @=300mm interval after installation, check the installed level and precision. After the check, peel off the protective film. Clear the removed film.
G. Joint sealing
Use the sealing materials as specified in the project and apply the joint design(width and height)as instructed from the sealant manufacturer. Typical sealing work includes cleaning of the joints, inserting back-up material, applying masking tape, applying primer, filling with sealant, tooling with palette knife, removing masking film and curving. As improper sealing work will affect the appearance and the waterproofing performance bf the joint, the sealing work must be conducted exactly based on the instructions from sealant manufacturer.
H. Clearing and cleaning
Clear and clean the working area every day after work. Especially, when the work is complete in a zone, clear, clean and transfer the area smoothly to the next location, in order to avoid hindering the next stage. Collect and clean unnecessary remains to the dump point everyday or transport out of the site immediately.

Touch-up Coating Method

When we need to repair scratches on the coating surface of CROWNBOND, we can repair (touch-up) them at room temperature. We use an air-cured type of lumifilon-based fluorocarbon paint for repair coating. The air-cured type paint consists of 2components: main agent and hardener. Mix them with 13: 1 ratio (main agent: hardener) and stir the mixture before use
After application, the air-cured type paint will reach surface dry in 1 hour and will show a satisfactory coating performance in a couple of weeks. However, the touch-up portion may show a slightly different appearance, because the coating appearance depends on the coating method. Especially in Metallic colors and sparkling colors, even an exactly matched paint may show a slight different appearance. In stone, Timber and Metal finishes, we use an intermediate solid color 10-90% of dear content.

Cleaning Method

(1) Removal of light surface soiling
Prior to applying a cleaner, we recommend a forceful water rinse cleaning from top to bottom, Low water volume with moderate pressure is better than considerable water volume with little pressure. Simultaneous physical rubbing is also effective Use a soft sponge or soft rags fully soaked in water.
A. Apply a water rinse with moderate pressure to dislodge the soiling. If this does not remove the soiling, test a simultaneous water rinse with a sponge. If the soiling is still adhering after dry, test a diluted mild detergent.
B. When you use a diluted mild detergent, use it with soft sponges or rags. Wash the surface with uniform pressure and clean the surface in a horizontal motion first and then in a vertical motion.
C. Minimize the drip and splash of the mild detergent and rinse the rundown immediately to avoid streaking. Clean the surface from top to bottom and follow with a thorough rinse with dean water.

(2) Cleaning of medium to heavy surface soiling
In order to remove medium to heavy soiling caused by grease and sealing material, some type of alcohol such as IPA (Isopropyl Alcohol), ethanol or n-hexane is used. Dilute these alcohols by 50% with water, Strong solvents or solvents-containing cleaners may have a detrimental effect on the coating surface. Do a spot test on a small unseen area. Wash the residues with soap and rinse with water.

(3) Caution
A. Strong solvents and strong cleaner may cause damage to the coating, Do a spot test on a small unseen are
B. Avoid abrasive cleaner. Do not use household cleaners containing abrasives
C. Do not rub excessively as it may change the coating appearance
D. Avoid drips and splashed. Remove the rundown as soon as possible.
E. Avoid extremely high and low temperatures. Extremely high temperatures will accelerate the chemical reaction, evaporate water from the solution and cause streaking. Extremely low temperatures will result in a poor cleaning effect. Perform cleaning work on a shaded side of the building under moderate temperatures.
F. Do not use paint removers, strong alkali or acid cleaners. Do not use strong organic solvents such as MEK(methyl Ethyl Ketone), MIBK(Methyl Isobutyl Ketone). Treclene (Tri-chloroethylene) or thinner.
G. Make sure that cleaning sponges and rags are grit free.
H. Do not mix cleaner

(4) Practical cleaning method
Cleaners and detergents are normally local products. A cleaner or a detergent widely available in a one country may not be available in another country. We attached an example of a practical cleaning method in "Appendix 10: Example of practical cleaning method" in section 4. To confirm the harmlessness of your cleaner, contact local distributors or our office. We will perform a test with your cleaner sample
