Instructions  for  Wall  Chine  Collé  Using  Starched-­‐based  Glue  Compiled  by  Sean  Caulfield,  University  of  Alberta    1)  Materials/Supplies  

a) Papers  for  the  paste-­‐up:  Generally  thin  washi  (rice  paper)  papers  such  a  kozo,  mulberry  or  gampi  works  best  for  this  process.  Rag  papers  can  be  used,  however,  they  are  much  more  difficult  to  take  down  because  water  needs  to  soak  through  the  front  of  the  paper  in  order  to  remove  the  work  from  the  wall.    

b) A  tube  of  Yamato  rice  paste  (actually  made  with  tapioca).  In  theory  any  starch  –based,  water  soluble  glue  should  work;  however,  I  know  from  experience  that  the  Yamato  brand  is  very  effective  for  this  purpose.  In  the  U.S.  it  can  be  ordered  from  McLain’s  Printmaking  Supplies.  (Look  under  “nori”  paste)  

c) Spray  bottle  d) Several  towels  e) Rags  f) A  piece  of  clear  acetate  or  dry  brush  mylar  that  is  cut  to  be  slightly  bigger  than  the  

largest  print  you  are  planning  to  paste-­‐up.  g) Level  and  pencil  h) Two  wide  brushes  (hake  brushes  work  best)  i) Squeegee  that  is  approximately  5  to  10  inches  long.  j) A  friend  to  help!  (It  is  really  a  two  person  job,  but  it  is  possible  to  do  alone  if  the  

print  is  no  too  large)    

 

2)  Getting  Started    a) Place  some  marks  on  the  wall  with  a  pencil  in  order  to  have  a  guide  for  pasting-­‐up  

your  print.  It  is  helpful  to  use  a  level  at  this  point  to  ensure  the  final  print  installed  correctly.  

b) Mix  the  Yamato  paste  at  a  ratio  of  about  60%  water  to  40%  glue.  It  is  surprising  how  little  glue  you  need  to  adhere  the  print  to  the  wall,  and  also  it  is  important  to  remember  that  the  thinner  you  make  the  glue  the  easier  it  will  be  to  take  off  the  wall  later.  With  this  in  mind,  you  might  experiment  by  increasing  the  amount  of  water  in  the  mixture  (70%  water),  particularly  if  the  print  will  only  be  up  for  a  short  period  of  time.  On  the  other  hand,  if  you  are  doing  a  more  permanent  installation,  or  adhering  to  a  rough  surface  such  as  cement,  you  can  increase  the  amount  of  glue  in  the  mixture  to  ensure  the  print  does  not  lift  with  changing  humidity  conditions.  (For  example,  I  have  done  installations  at  public  galleries  that  have  been  up  for  several  years,  and  for  these  I  used  a  larger  percentage  of  glue  in  the  mixture.)  

       

           

3)  Applying  the  Glue  a) Place  the  print  face  down  on  the  center  of  the  acetate.  Begin  to  wet  paper  with  the  

spray  bottle  starting  in  the  middle  of  the  print.  Use  one  of  the  hake  brushes  (one  brush  for  water  only)  to  work  out  wrinkles  as  you  move  to  the  edges  of  the  print.  Once  the  print  has  been  wet  and  is  lying  flat  on  the  acetate  take  one  of  the  towels  and  blot  the  print  dry.  The  paper  should  be  wet  but  not  too  wet  before  you  apply  the  glue  as  too  much  water  can  impact  the  effectiveness  of  the  paste.    

b) Apply  the  glue  using  the  other  hake  brush  (one  brush  for  glue  only)  along  the  edges  of  the  print.  Apply  glue  in  an  area  only  about  2  or  4  inches  in  from  the  edge  of  the  print.  It  is  important  to  note  that  you  do  not  have  to  apply  glue  over  the  entire  surface  of  the  print  as  this  will  make  it  much  more  difficult  to  remove  later.  However,  if  you  are  doing  a  more  permanent  installation  you  can  apply  the  glue  across  the  entire  surface  of  the  paper  starting  in  the  middle  of  the  print  and  working  out  to  the  edges.    

c) Clean  the  edges  of  the  acetate  by  spraying  a  little  water  on  a  rag  and  wiping  the  excess  glue  off.    

     

         

     4)  Pasting  the  Print  to  the  Wall    

a) While  the  glue  is  still  wet  pick  up  the  acetate  sheet  by  the  edges  and  carry  it  to  the  wall.  (The  print  will  stay  fixed  to  the  acetate  because  it  is  wet.)  

b)  At  this  point  have  your  assistant  hold  either  the  top  or  the  bottom  of  the  acetate  slightly  away  from  the  wall  (depending  on  where  you  placed  your  pencil  marks).  The  take  the  other  end  of  the  acetate  and  place  it  against  the  wall.  Press  the  print  against  the  wall,  and  slowly  press  the  rest  of  the  print  down.  (Moving  up  or  down  depending  where  your  assistant  is  holding  the  acetate.)    

c) Once  the  entire  print  is  in  contact,  take  your  squeegee  and  apply  pressure  through  the  acetate  against  the  wall.  Work  from  the  middle  of  the  print  out.    

d) Now  it  is  time  to  slowly  pull  the  acetate  away  from  the  print.  If  all  goes  well  the  print  should  stay  on  the  wall  and  release  from  the  acetate.  If  the  print  sticks  to  the  acetate  instead  of  the  wall,  try  working  from  another  edge  instead.    

e) If  you  have  placed  the  print  incorrectly  you  can  remove  at  this  point  without  too  much  trouble  as  long  as  the  work  is  still  wet.  If  it  dries  then  you  must  follow  the  removal  instructions  below.  

f) The  finally  step  is  to  take  a  dry  towel  and  blot  the  print  against  the  wall  (particularly  around  the  edges  where  the  glue  is.)  Do  not  worry  if  there  are  some  small  wrinkles  or  minor  bubbles  in  center  of  the  print  that  does  not  have  glue.  These  will  stretch  out  once  the  print  dries.  

 

 

           

               

           

Taking  the  Prints  Down  a) If  the  print  was  put  up  in  sections,  start  removing  the  work  by  selecting  one  square  

and  applying  a  generous  amount  of  water  to  the  surface  using  a  spray  bottle  or  soft  brush.  Some  sections  of  the  print  will  have  edges  that  are  overlapped  by  another  print,  so  it  is  best  to  start  with  the  outermost  layer.  In  most  cases  this  should  be  the  bottom  sections  of  the  print.  

 b) Continue  to  spray  (wet)  the  surface  of  the  print  until  all  the  paper  changes  to  a  

darker  tone.  It  is  a  good  idea  to  have  a  sponge  or  a  towel  handy  at  this  point  to  collect  any  extra  water  that  might  be  dripping  down  from  the  wall.  

 c) After  a  section  of  the  print  has  had  enough  water  applied  to  it  WAIT  about  10  to  15  

minutes  to  allow  the  starch  glue  to  release.  It  can  help  to  spray  some  additional  water  at  this  time  to  be  sure  the  surface  stays  wet.    As  you  are  waiting  you  can  also  begin  to  spray  the  next  section  of  the  print.  

 d) Start  to  remove  the  print  from  the  wall  by  carefully  lifting  an  edge,  and  then  peel  the  

paper  away  from  the  wall.  If  paper  fibers  start  to  separate,  and  some  of  the  paper  is  left  on  the  wall,  it  is  best  to  wait  a  bit  longer  and  add  more  water.  However,  if  you  have  waited  long  enough,  the  glue  should  release  easily  and  the  print  can  be  pulled  from  the  wall  without  too  much  difficulty.  (If  a  few  fibers  stay  on  the  wall  the  can  be  cleaned  later  with  a  sponge.)  

 e) Once  you  have  removed  one  section  of  the  print  place  it  FACE  down  on  a  clean  

section  of  the  floor  (or  on  a  clean  piece  of  blotting  paper  or  newsprint),  and  let  it  dry.  The  paper  should  take  about  30  to  60  minutes  to  dry  and  then  the  glue  will  no  longer  be  active  and  the  paper  can  be  rolled.
