Application steps

1
Render with removal of existing paint
Remove the paint from the substrate down to the level of the existing render.
2
One-component ready-mixed waterbased adhesive in polyurethane dispersion MAPEWRAP EQ ADHESIVE
Apply a first, even layer with a brush or roller. Please refer to the MAPEWRAP EQ SYSTEM data sheet.
3
Primed bi-directional glass fibre fabric MAPEWRAP EQ NET and second coat of adhesive MAPEWRAP EQ ADHESIVE
Immediately apply the special fabric and spread and flatten it out by hand (wear protective waterproof rubber gloves when carrying out this operation), making sure there are no folds or creases, then go over the surface several times with a MAPEWRAP ROLLER so that the adhesive completely penetrates into the fibres of the fabric.
Apply a second coat of adhesive with a brush or roller while the first layer is still fresh.
Please refer to the MAPEWRAP EQ SSYSTEM data sheet.
4
One-component ready-mixed waterbased adhesive MAPEWRAP EQ ADHESIVE
Apply the second coat while the first coat is still fresh. Use a MapeWrap Roller to remove any air bubbles.
5
Cementitious skimming mortar
Apply and spread the skimming mortar with a smooth metal trowel.
6
Acrylic primer
Apply the product with a brush or roller to even out the surface and to promote adhesion of the successive coat of paint.
7
Hygienising, crack-bridging elastomeric paint
Once the primer is dry, apply at least 2 coats of paint with a brush, roller or by spray to completely cover the surface.
