Fresco Painting - Modern Methods And Techniques For Painting In Fresco And Secco

FRESCO PAINTING- Modern Methods and Techniques for Painting in Fresco and Secco By OLLE NORDMARK. PREFACE: This book has been written for the painter in fresco, who wishes to acquire enough knowledge of the craft to enable him to supervise, guide and efficiently work with the craftsmen plasterers who are put in charge of the preparation of his materials and wall and who will assist him as the finishing plasterers throughout the period of painting. It should be remembered that the surface of the so-called Intonaco, must yield the best possible working conditions, giving the painter the longest possible time to execute the part of the wall intended for a days work. In order that such a condition should prevail, a thorough knowledge of the materials used in the practice of fresco painting must be acquired through the practical utilization of a series of operations to obtain necessary ultimate results. Stress is, therefore, laid upon the fact that the painter him self must guide and guard the preparation of his materials and the different layers of mortar which build up the fresco ground, the foundation for the painting. Also, if he is not prepared himself to do the work, he must be able to give final full direc tions for the Intonaco or painting surface, the richness of the mixing and its perfect application which in itself requires experienced handling of tools in the piece-meal plastering of the wall, all of which is the groundwork for the actual painting. This HANDBOOK, therefore, will endeavor to explain the practice of fresco and fresco-secco painting in connection and collaboration with the trade from which it was derived the building trade.

WALLS. CHAPTER ONE: THE QUESTION of a suitable wall for the fresco-mural, or how to make any available area a permanent foundation for the plaster coats making up the fresco ground, has vexed the fresco painter from ancient times to our days. BRICK WALLS Generally it can be said that the old-fashioned brick wall made from handmade bricks is still the ideal wall for the fresco mural. Bricks baked to a fresh looking red and laid in lime-sand mortar constitute that kind of a wall. Old plastered walls must first have the plaster removed. Old as well as new walls are cleaned with a weak solution of HYDROCHLORIC ACID, washed with hot water and then sprayed and rinsed with cold. During the spraying the wall is examined for non-absorbent bricks of a muddy violet or clincer grey color. All such bricks baked and burnt beyond the temperature of the fresh red color must either be insulated by waterproofing or, better still, replaced with good bricks to remove the ever present possibility of EFFLORESCENCE. Waterproofing is done by painting over with an ASPHALT type of WATERPROOFING which will still allow the mortar to cling to the safeguarded brick. Deep hollows and faulty bricks are filled out and repaired with lime-sand mortar, 1-2 mixture with brick chips mixed in
