European foreword
This document (CEN/TR 16958:2017) has been prepared by Technical Committee CEN/TC 226 “Road
equipment”, the secretariat of which is held by AFNOR.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
There are many situations in which road marking removing or masking become necessary. This
document is intended to give some guidance about how to proceed in these cases.
This Technical Report (TR) describes a number of methods for removal and masking and gives guidance
for the appropriate selection. Not all methods are valid or recommended in all cases; some methods are
limited by the kind and nature of existing road marking and the pavement surface. Also the cost of the
operation is depending on the amount of marking to be removed.
In some countries these operations are regulated, in particular in some countries masking the existing
road marking only with black paint is forbidden.
The quality of the removal or masking or any combination of them, may be not enough or result in a
new “phantom line”, which, under particular illumination conditions, may be more visible than the real
road markings (introducing confusion) or may change the surface texture (introducing hazard). Works
shall be done in such a way that the risk for confusion or hazard for drivers be minimized.
Furthermore, recommendations are given for some frequent works such as: removing and masking
road studs, removing wet paints, removing curing membranes in new cement concrete pavements and
cleaning existing road markings.
1 Scope
This document provides guidance for removal or/and masking existing road markings. It includes
methods of removal and criteria for selecting the removal method, as well as the requirements for the
masking materials and the performance requirements of the resulting surface.
It does not apply to removable temporary road markings, which shall be removed in accordance to the
manufacturer instructions.
Some recommendations are given for removing and masking road studs, removing wet paints,
removing curing membranes in new cement concrete pavements and cleaning existing road markings.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
removal
permanent elimination of road markings, that may be partial or complete
3.2
masking
temporary hiding of existing road marking using a topcoat of a material similar in color, luminance and
specular gloss, to the pavement surface
3.3
phantom line
shadow line
road marking or print resulting from removal or masking process
3.4
specular gloss
ratio of the luminous flux reflected from an object in the specular direction for a specified source and
receptor angle to the luminous flux reflected from a glass with a refractive index of 1,567 in the specular
direction
4 Criteria for selecting removal or/and masking procedure
There are situations in which existing road marking shall be obliterated so as to not function as a
recognizable road marking (phantom line). In order to do it, Removal or Masking techniques may be
used. Removal may be done totally or partially and masking may be done as the unique procedure or
after a partial removal. In order to take the good decision it is also important to know if the obliterated
road marking shall be renewed or not and if the surface will be repaved or not. Table 1 gives a guidance
to apply these criteria.

When a road marking has to be applied and removed after a short period of time, (for instance less than
6 months) removable temporary materials, in accordance to EN 1824, shall be used.
Removal of such removable temporary materials shall be done in accordance to the manufacturer
instructions.
For each case, some criteria are given in the following:
A.1 When permanent changes in road markings lay out occurs (as for instance. new
exits/entrances from main road, exchange from continuous line to interrupted line,
direction of arrows, etc); unwanted road markings should be totally removed.
A.2 When the existing road marking has poor adhesion or is covering less than 70 % of
the marked area; partial removal can be accepted. The removal processing shall not
adversely damage the pavement surface. There are limits (see Clause 6.1.2) for
changes in surface texture and grooving and for the residual road markings. If
damage to the pavement exceeds the limits, then for a complete obliteration of the
road marking, a complementary masking with a blend of bitumen and fine aggregate
may be used to minimize the difference in level and appearance.
A.3 When permanent changes in road marking occur; unwanted road marking shall
never be obliterated by masking.
A.4 Same comments as in A.2.
B.1 Existing road markings (formed for one or several layers) that have lost adhesion to
the pavement or inter- layers (more than 30 % of the marked area is affected) shall
be totally removed before renewal.
B.2 Existing multilayer road markings not fulfilling with the essential requirements
(EN 1436) may be renewed w
