Brush Head Moratorium
Moratorium on Brush Head Technology
(updated February 17, 2016 by Curling Canada)
Given that events have caused the need for clarification regarding brushing instruments, the
Steering Committee has modified the Curling Canada statement (below) for application during the
2016 Optimist U18 International Curling
The purpose of the moratorium is to remove the uncertainty that hangs over the field of play by
ensuring a level playing field while protecting the integrity of the sport and the spirit of
fair play. This will require voluntary player compliance without the intervention of
Only brushes and brush heads available for sale to the public at retail outlets will be
allowed on the field of play.
No modified, custom-made or homemade brushing equipment will be allowed on the field of
play. This does not apply to branding / cosmetic related modifications nor does it apply to
compliant brush heads that have been re-conditioned or recovered for retail
Brush head fabric that have been embossed / sealed / textured / modified from its
original woven form will not be allowed on the field of play.
For brush head fabric to be allowed on the field of play, the fabric must have a woven
appearance that is visible to the “naked eye”. The intent is to ensure the fabric makes
contact with the ice as opposed to the embossed / sealed coating of the
Brush heads containing “hardening” or “stiffening” materials inserted between the outer
fabric and the internal cushioning material of the brush head are not allowed on the
field of play. These materials may include but are not limited to: plastic, fibreglass,
wood, and Teflon. In addition, brush heads that are constructed in a manner that greatly
reduces the “normal” amount of compression may not be allowed on the field of play as
determined by the Chief Umpire.
All hair or hog hair brushes are now included in the Moratorium and deemed
non-compliant. Hair or hog hair brushes may be used by the skip or vice skip in the
house at the playing end. But their sweeping with a hair hog or hair brush can only be done
behind the tee-line or for the tick shot. Hair or hog hair brushes may also be used as part
of the delivery. Combination hair/fabric brushes are also considered
– Teams currently using brush head technology not in compliance with the above moratorium may
If applicable, reversing the brush head fabric to place the fibre weave on the exterior [in
contact with the ice]; or,
Utilizing alternate brush head fabric comprised of fibre weaves that are visible to the
“naked eye”; or,
If applicable, removing any “hardening or “stiffening” inserts from between the fabric and
cushioning material, or using an alternative brush.
Players and coaches will be responsible for ensuring any brush brought on to the field of
play is compliant with the moratorium.
Once a player has selected one approved brush for that game, no replacement of that brush,
brush head or brush head fabric shall be made without the approval of the assigned
Replacement of a brush head or brush head fabric would only occur in extreme circumstances
to be determined by the umpire. As described, the circumstance must be extreme in nature,
and not as a result of intentional damage to the brush by the player. If the damage is as a
result of intentional damage by the player, the umpire will decide what sweeping broom will
be allowed. A ‘wet’ broom is not considered an extreme circumstance.
Players may exchange brushes between themselves with the exception of exchanging with the
skip (person in charge of play for the team).
If a player intends to bring into the field of play a delivery device to be utilized as a
delivery device only, and that has the ability to be switched to a sweeping device, then
the declared delivery device shall be marked in such a manner that it would be visible to
an umpire if the device was used as a sweeping device. (Possible markings: bright duct
tape, survey tape).
Penalty for sweeping with a throwing broom: the delivered stone shall be removed from play
and all affected stones shall be replaced to their original position. The throwing broom
shall be returned to play as a throwing broom.
Random inspections of equipment by an umpire may be carried out during the event and during
a game. Players may request an umpire inspect a brush prior to or during a

the processes, listened to concerns of players, and have further developed how to approach the
Moratorium in the field of play.

used including throwing brooms.

If a player is found to be using a brush that is not allowed on the field of play under this
moratorium, the offending team will forfeit that game.

to perform various duties, as required.
The Chief Umpire is authorized to make decisions regarding this Moratorium not specifically
covered in this protocol.
All decisions of the Chief Umpire regarding this Moratorium are final.
