may be used if necessary. Clean wet surfaces shall be between 6 and
8 pH.
5.2.3 Rust Removal
Paint shall be applied to surfaces, at maximum, eight (8) hours
after rust removal. In no case shall clean surfaces be left
overnight without being painted. In the event that rust reappears
on any surface, it shall be sand blasted again.
5.2.3.1 Abrasive blasting
Rust shall be removed by abrasive blasting, in accordance with
the SSPC-SP standard corresponding to the cleaning grade
established for the selected painting system. After preparation,
the appearance of the surface must coincide with the corresponding
figure in ISO-8501 standards.
Blasting shall not cause surface damage or distortion.

Surface preparation by wet blasting may be used in certain
environments at the discretion of the Engineer, in order to provide
increased safety against sparking, to minimize atmospheric and
surface pollution or to prepare surfaces which are salt
contaminated and spent much of their time in wet conditions. Wet
blasting shall be confirmed as suitable by the Manufacturer of the
paint that is to be applied to the surface.
Compressors shall supply air free of oil and water, with the
necessary flow and pressure in the nozzle.
5.2.3.2 Manual or Mechanical Brushing
This method shall be used only where blast cleaning is
impractical and with the approval of the Engineer, for repairing
and patching up small damaged areas. Final surface appearance shall
be equivalent to cleaning grade of standard ISO-8501 specified in
each case.
This method shall also be used to obtain adequate roughness on
cold-rolled steels.
5.2.3.3 Chemical Cleaning
The removal of rust using chemicals (pickling, etc) shall be
subject to the explicit approval of the Purchaser.
5.3 PAINTED STEEL SURFACES
5.3.1 Surfaces with Defects
If the defects to be repaired cover small zones, they shall be
brushed with a mechanical brush down to a firmly adhered coat of
paint or, if there is no such coat, down to the bare metal. The
dust resulting from brushing shall subsequently be cleaned,
followed by the painting system specified.
If the defects to be repaired cover more than 20% of the painted
surface, or are spread throughout the surface (regardless of the %)
all the layers of defective paint shall be completely removed and
the surface shall be prepared and completely painted in accordance
with this specification.

5.3.2 Weld Areas and Screw Joints
All weld joints shall be continuous; if this is not possible,
the gaps will be sealed with repaintable acrylic or polyester resin
filler on both sides of the joint, as long as they are
accessible.
After welding, the area shall be cleaned of grease and brushed
before painting. Care shall be taken to ensure the complete removal
of weld splatter, test fluid residues, burnt paint, etc. The
surface affected by the weld shall be left prepared to be
completely painted like the rest of the component.

In this type of joints, the use of paints that plastifies with
pressure, used as lubricants is not permitted.
5.3.3 Surfaces Free of Defects
If these surfaces have to be painted, the painted surface shall
be cleaned with cloths or brushes using solvents suited to the
already applied paint. If the type of paint is not known, tests
shall be carried out on small surface areas with different solvents
or detergents until it can be established which of them leaves the
surface clean without affecting the coating. Very smooth surfaces
will have to be lightly shotblasted or brushed to obtain adequate
roughness for the paint to adhere. Once the surface is clean and
dry, the specified coats of paint shall be applied.
5.4 GALVANIZED STEEL
5.4.1 New Galvanized Surfaces
These surfaces shall be cleaned with a suitable detergent and
subsequently washed with water. Solvents may have to be used to
remove oil and grease.
Very smooth surfaces will have to be lightly shotblasted or
brushed to obtain adequate roughness for the paint to adhere and
then, following approval, epoxy primer with accredited adherence to
galvanized surfaces or similar product will be applied.

6.13 INTUMESCENT PAINT
6.13.1 General
Intumescent paint is a product whose dry film reacts to a heat
source, producing an increase in volume of said film, in the form
of foam, which acts as a heat insulation layer protecting the
substrate from the heat during a certain length of time.
The time that a load-bearing structure complies with its
function without collapsing in the event if fire is called fire
stability (EF). The "fire stability" period for a structure depends
on the thickness of the intumescent paint system and on the shape
of the structure.
6.13.2 Intumescent System
Intumescent systems should also guarantee anticorrosive
protection of the steel structure.

An intumescent system is comprised of one layer of anticorrosive
primer, one layer of an intumescent paint and one topcoat
layer.
The topcoat is a protective sealing layer that can be applied
over the intumescent paint to protect it against humidity and the
atmosphere and that can also have a decorative function.
An intumescent paint system shall be applied to those surfaces
of load-bearing structures that require a 60 minute fire stability
(indicated in the corresponding technical specification).
The intumescent systems used must comply with the requirements
below, said requirements being certified by the appropriate
authorities:
a) Fire stability, EF-60 min., determined with EN-ENV
13381-4:2005 ("Test method to determine the contribution to the
fire stability of structural elements, through the application of
protection to the steel structural elements") or another similar
internationally recognized standard for the applied thicknesses.
The thickness of the system is considered to be the sum of the
primer, intumescent and topcoat film thicknesses.
b) The anti-corrosive primer should be combustible but not
flammable. It should be compatible with the intumescent paint.
c) The topcoat should be combustible but not flammable. It
should be compatible with the intumescent paint and should not
impede the development and consequent expansion of the foam in the
event of fire.
6.13.3 Shape factor or Massivity
The thicknesses of intumescent paint to be applied are
determined as a function of the shape factor or massivity of the
structure to be protected, which is defined as being the ratio
between the perimeter of the section exposed to fire, expressed in
meters, and the area of said steel section, expressed in square
meters.
Massivity (m-1)= )(m section steel of Area
(m) section steel of Perimeter2
The bigger the massivity of the steel section, the higher the
thickness of the dry film required to obtain a certain stability
against fire.

Supplier shall inspect the surface and the warranty granted shall
cover the complete painting system. If after inspection the
Supplier refuses to grant the warranty, he shall accordingly inform
the Purchaser in writing, giving the reasons for his refusal.
8.3 PAINTS APPLIED IN THE WORKSHOP
If during surface preparation defects are detected in the
composition or in the application of painting systems, the Supplier
shall remove and repair the defective coatings at his own expense.
