Residential Compound Rust Remediation

SCOPE OF WORK

The existing prefabricated residential units use metal panels of galvanized steel with an organic protective coating. See Trimo technical instructions for the use and maintenance of Trimo products after the Coating Restoration specifications for said units.

Follow Coating Restoration specifications for surface preparation, repair, and application of rust inhibitor for prefab building framing, ceilings, and wall panel components.

Metal deterioration exceeding repair requirements must be replaced. If the damage exceeds 1/3 depth of the sheet metal and/or 1/4 depth of steel framing, remove damaged area and replace with new metal or hollow metal section, then follow coating specifications.

Metal repair must not damage the adjoining finish. Follow manufacturer's instructions for material limits, use of shears and protective layers. Machining is not advised to cause additional burrs or damage to adjacent material. See below for Trimo contact, Uros Murn, to obtain ordering information for full panel replacement.

PART 3 – EXECUTION

3.1 EXAMINATION

A. Do not begin installation until substrates have been properly prepared; notify COR of unsatisfactory conditions before proceeding. If substrate preparation is the responsibility of another installer, notify COR of unsatisfactory preparation before proceeding.

B. Proceed with work only after conditions have been corrected and approved by all parties, otherwise application of coatings will be considered as an acceptance of surface conditions.

C. Previously Painted Surfaces: Verify that existing painted surfaces do not contain lead based paints, notify COR immediately if lead based paints are encountered.

3.2 SURFACE PREPARATION

A. General: Surfaces shall be dry and in sound condition. Remove oil, dust, dirt, loose rust, peeling paint or other contamination to ensure good adhesion.

1. Remove mildew before painting by washing with a solution of 1 part liquid household bleach and 3 parts of warm water. Apply the solution and scrub the mildewed area. Allow the solution to remain on the surface for 10 minutes. Rinse thoroughly with clean water and allow the surface to dry a minimum of 48 hours before painting. Wear protective glasses or goggles, waterproof gloves, and protective clothing. Quickly wash off any of the mixture that comes in contact with your skin. Do not add detergents or ammonia to the bleach/water solution.

2. Remove items including but not limited to thermostats, electrical outlets, switch covers and similar items prior to painting. After completing painting operations in each space or area, reinstall items removed using workers skilled in the trades involved.

3. No exterior painting should be done immediately after a rain, during foggy weather, when rain is predicted, or when the temperature is below 10 degrees C (50 degrees F), unless products are designed specifically for these conditions. On large expanses of metal siding, the air, surface and material temperatures must be 10 degrees C (50 degrees F), or higher to use low temperature products.

B. Galvanized Metal: Clean per SSPC-SP1 using detergent and water or a degreasing cleaner to remove greases and oils. Apply a test area, priming as required. Allow the coating to dry at least one week before testing. If adhesion is poor, Brush Blast per SSPC- SP7 is necessary to remove these treatments.

C. Steel: Structural, Plate, And Similar Items: Should be cleaned by one or more of the surface preparations described below. These methods are used throughout the world for describing methods for cleaning structural steel. Visual standards are available through the Society of Protective Coatings. A brief description of these standards together with numbers by which they can be specified follow.

USAID South Sudan Engineering Support Program (ESP)

09 01 90.92 Coating Restoration - Page 7 of 8

1. Solvent Cleaning, SSPC-SP1: Solvent cleaning is a method for removing all visible oil, grease, soil, drawing and cutting compounds, and other soluble contaminants.

Solvent cleaning does not remove rust or mill scale. Change rags and cleaning solution frequently so that deposits of oil and grease are not spread over additional areas in the cleaning process. Be sure to allow adequate ventilation.

2. Hand Tool Cleaning, SSPC-SP2: Hand Tool Cleaning removes all loose mill scale, loose rust, and other detrimental foreign matter. It is not intended that adherent mill scale, rust, and paint be removed by this process. Before hand tool cleaning, remove visible oil, grease, soluble welding residues, and salts by the methods outlined in SSPC-SP1.

3. Brush-Off Blast Cleaning, SSPC-SP7 or NACE 4: A Brush-Off Blast Cleaned surface, when viewed without magnification, shall be free of all visible oil, grease, dirt, dust, loose mill scale, loose rust, and loose paint. Tightly adherent mill scale, rust, and paint may remain on the surface. Before blast cleaning, visible deposits of oil or grease shall be removed by any of the methods specified in SSPC-SP 1 or other agreed upon methods.

4. Power Tool Cleaning to Bare Metal, SSPC-SP11: Metallic surfaces that are prepared according to this specification, when viewed without magnification, shall be free of all visible oil, grease, dirt, dust, mill scale, rust, paint, oxide corrosion products, and other foreign matter. Slight residues of rust and paint may be left in the lower portions of pits if the original surface is pitted. Prior to power tool surface preparation, remove visible deposits of oil or grease by any of the methods specified in SSPC-SP1, Solvent Cleaning, or other agreed upon methods.

3.3 INSTALLATION

A. Apply all coatings and materials with the manufacturer’s specifications in mind. Mix and thin coatings according to manufacturer’s recommendations.

B. Do not apply to wet or damp surfaces.

C. Apply coatings using methods recommended by manufacturer.

D. Uniformly apply coatings without runs, drips, or sags, without brush marks, and with consistent sheen.

E. Apply coatings at spreading rate required to achieve the manufacturers recommended dry film thickness.

F. Regardless of number of coats specified, apply as many coats as necessary for complete hide, and uniform appearance.

G. Inspection: The coated surface must be inspected and approved by the COR just prior to the application of each coat.

1 Introduction

The instructions are intended for the inspection and maintenance of Trimo products and flashing elements made of galvanised pre-painted sheet metal, protected with the coil coating organic protective coatings. These coatings provide long-term resistance and stability and aesthetic appearance of individual elements and the final facility.

On a regular basis a caretaker or user of facilities and persons with adequate professional qualifications shall inspect, maintain and organise cleaning of all structural elements of the facility in scope of regular maintenance works. An inspection carried out minimally once a year is obligatory; it may be carried out even several times if the environment is less favourable. Conclusion of a maintenance contract with the contractor is recommended.

The table at the end of this document presents a list of required procedures and measures that are to be implemented during the annual inspection of the facility, instructions for damage repairs, washing of roof and façade panels and other aspects of maintenance.

In case of questions about the inspection and maintenance of hot galvanised pre-painted sheet metal, Trimo cladding, roof and façade products, you are kindly requested to contact the Trimo service and repair department.

2 Protection of Trimo elements

Trimo elements viz. panels consist of a filling (mineral wool, honeycomb) and cladding made of galvanised pre-painted thin sheet metal.

Steel sheet metal is preliminary hot-dip galvanised in compliance with EN 10346, and additionally protected by organic coating in accordance with the »coil-coating« process (EN 10169).

The following basic types of organic coatings viz. protection are applied to steel sheet metal:

• based on SP polyester

• based on PVDF polyvinylidene fluoride

• based on PUR polyurethane

• based on PUR/PA polyamide modified polyurethane

• based on PVC polyvinyl chloride, coating or film

Individual types of organic protection with the basic characteristics are presented in Table 1.

Table 1: Basic characteristics of an individual type of organic coating or protection

Legend:

•••• suitable without reservations ••• very suitable •• suitable • conditionally useful /contact Trimo - not useful

Note: There should be no sudden cooling to the dew point during cleaning. Otherwise condensate can appear. See Table: Presentation of dew point at a certain temperature of the room and relative humidity. In case of cooling the working temperature should be min. 3°C above the dew point.

Technical instructions for the use and maintenance of Trimo products | EN | May 20212

The condition of screws can be easily established by unscrewing some randomly selected screws on various parts of the facility. The condition of seals, joints between seals and fixing elements and possibly rust at screws is to be inspected thoroughly. A seal has to be pressed well against sheet metal so that tightness of a joint is provided. Insulation in panels can eventually get slightly compressed which results in a slot between a seal and a panel, and therefore screws have to be regularly inspected. Loose screws are to be tightened, and rusted screws or worn seals replaced.

2.1 Instructions for prevention of damage to products

The instructions for handling of panels and elements are to be followed in order to be able to prevent mechanical damage.

Only scissors and saws that do not heat the cutting spot to a high temperature are allowed for additional cutting of panels or elements. High temperature causes destruction of anti-corrosion protection in the immediate vicinity of the cut. Therefore the use of angle grinders is strictly prohibited for this purpose!

A protective element (e.g. cardboard) is to be inserted between a drilling machine and a façade panel during drilling and riveting of the edges and flashing in order to prevent any additional mechanical damage to a panel and falling of chips on a pre-painted thin sheet metal.

Work producing hot filings (i.e. welding, cutting) is strictly forbidden in the vicinity of panels. Panels have to be adequately temporarily protected if any additional works are carried out in the immediate vicinity (i.e. concreting, plastering, asphalting etc.).

Marking or scratching by wire nails or similar sharp objects is prohibited since it may damage the protective layer.

3 Regular annual inspection

The purpose of the inspection is elimination of any possible shortcomings / deficiencies during the use of the facility.

The facility consisting of façade and roof elements and other end / closing pieces can be exposed to various weather and temperature changes.

Regular maintenance is therefore of vital importance for long service life of a facility.

In accordance with good practice it is necessary to carry out inspection of panels and other structural elements of the facility minimally once a year.

In scope of maintenance special attention is to be paid to the following:

• sections where dirt, smoke soot, condensate and water may accumulate

• cleaning of inflow pipes, roof valleys and gutters

• tightening of all structural elements on the structure

• control of all seals on the facility

Activities relating to the regular annual inspection are stated in Annexes 1-6 at the end of the document:
