INTERNAL WALLS: PREPARATION OF SUBSTRATES OLD WALLS PAINTED WITH TRANSPIRANT WATER-BASED PAINT SUBSTRATES WITH A “CRUMBLY” SURFACE Procedure Prepare the walls by mechanically removing all traces of surface dust and or areas where surface is loose or detached portions to obtain a clean, solid, strong substrate. Restore the areas where surface has been removed to bring the substrate back to its original condition. Wait until the skimming mortar has completely cured, if applied, and prime the substrate. If no areas of substrate need to be restored, or if priming only is deemed sufficient after checking...

INTERNAL WALLS: PREPARATION OF SUBSTRATES I.1.1.1 Natural-finish, lime-cement skimming mortar for “fresh” and “cured” internal and external render Supply and application of natural-finish, grey or white, lime-cement skimming mortar for “fresh” or “cured” internal and external traditional rough-finish render or pre-blended render, made from hydraulic and aerated binders, selected quartz aggregates and special powdered additives (such as Planitop 530 produced by MAPEI S.p.A.), before decorating with thin coats of mineral or synthetic paint or coatings. Apply the mortar after adequate preparation...

INTERNAL WALLS: PREPARATION OF SUBSTRATES I.1.1.2 Natural-finish, cementitious skimming mortar for “cured” internal and external concrete and render Supply and application of natural-finish, grey or white, cementitious skimming mortar for “cured” internal and external concrete and render, made from cementitious binders, selected aggregates in a granulometric curve, special powdered additives and powdered synthetic polymers (such as Planitop 540 produced by MAPEI S.p.A.), before decorating with thin coats of mineral or synthetic paint or coatings. Apply the mortar after adequate preparation of...

INTERNAL WALLS: PREPARATION OF SUBSTRATES I.1.1.3 Fine-grained, lime-cement skimming mortar for “fresh” and “cured” internal and external render Supply and application of fine-grained, white, lime-cement skimming mortar for “fresh” or “cured” internal and external traditional rough-finish render or pre-blended render, made from hydraulic and aerated binders, selected fine-grained limestone sand, special additives and powdered synthetic polymers (such as Planitop 560 produced by MAPEI S.p.A.), before decorating with thin coats of mineral or synthetic paint or coatings. Apply the mortar after adequate...

INTERNAL WALLS: PREPARATION OF SUBSTRATES I.1.1.4 Lime and gypsum skimming mortar for “cured” and “dry” internal gypsum or anhydrite render Supply and application of fine-grained, white, lime and gypsum skimming mortar for “cured” or “dry” internal and external traditional rough-finish or pre-blended gypsum, anhydrite or lime-cement render, made from hydrated lime, gypsum, ultra-fine marble powder, rheologic additives and powdered synthetic polymers (such as Planitop 580 produced by MAPEI S.p.A.), before decorating with thin coats of mineral or synthetic paint or coatings. Apply the mortar after...

INTERNAL WALLS: PREPARATION OF SUBSTRATES OLD WALLS PAINTED WITH WASHABLE WATER-BASED PAINT SUBSTRATES WITH A COHESIVE SURFACE Procedure Prepare the walls by mechanically removing all traces of surface dust and loose or detached portions to obtain a solid, strong substrate. Restore the areas where portions have been removed. Wait until the skimming mortar has completely cured, if applied, and prime the substrate. If no areas of substrate need to be restored, apply a coat of Malech primer (see section I.2.1.1) or Silancolor Primer (see section I.2.1.2) diluted according to requirements.
