Svenska föreningen för textilkonservering 26 Dec 2017 For example in the double pressure mount method a stretcher frame is made from poplar wood, to this UV filtered plexiglass or aluminium honeycomb sheet is screwed. A barrier paper is followed by layers of polyester batting. Pressure on the textile can be controlled by varying thicknesses of the batting at the edge of the mount. Care should be taken to avoid a pillowing effect (i.e that the textile is stretched over a mound of batting and is under higher tension at its centre than at edges.) By creating dips (or wells) in the batting it is possible to support for example tassels without them subsequently being squashed by the mount (see blog link below for more information). The batting is covered with pima cotton plain weave on which the textile to be mounted is placed. A layer of plexiglass follows. The whole is held in place with a mat made of museum board wrapped in pima cotton, and over this a specially constructed lid on UV filtered plexiglass is placed.

Zaharia Pressure Moun8ng Workshop Stockholm, May 12, 2017 Page 4 Florica warned that they have seen inconsistencies with supply of batting, they have noted variation in fibre density, and if a large roll has been tied for shipping the ties may leave permanent lines. Any wood used is varnished with polyurethane varnish to reduce the risk of off gassing. It is possible to colour the pima fabric as a colour compensation technique so that holes in the mounted textile are less obvious. Föreningen fyller 50år 8
