Survey: Carry out before installation commences.
Preparation:
Clips, hangers, supports and associated type attachments to be placed by others prior to spray application.
Ducts, piping and other suspended items to be installed after SonaSpray application or consult contractor.
Pattresses to be installed for light fittings / smoke sensors etc prior to SonaSpray application to allow firm fixing for the fitting. Pattresses to be made from plasterboard or wood not MDF which can stain the material when wet.
Wood pattresses to be fully painted to prevent any staining of material from contaminants.
Pattresses to be slightly smaller than the base of the fitting to ensure the fitting covers the pattress which should not be seen.
Pattresses to be the same thickness as the SonaSpray, the contractor to spray to the edge of the pattress and brush clean the face.
A finishing edge will be required for the SonaSpray where it does not occur naturally e.g. around an opening for services to pass through a ceiling or around a staircase opening. Consult with the contractor.
The surface to be sprayed shall be inspected prior to application to determine if priming/sealing is required to ensure bond and/or to prevent discolouration by migratory stains. Prime seal accordingly. Consult with the contractor.
The contractor must install as necessary protection to other finished surfaces from
overspray.
The manufacturer recommends 8 air changes per hour immediately after spraying for best drying conditions. Where this does not occur naturally, introduce fans and open windows. Consult with the contractor.
