How to repaint an internal room infested with mold?

PROBLEM: Internal room infested with mould

The main factors that influence the growth and spread of mold and algae are as follows: water, temperature, and nutrients.

Water. In the absence of water, life cannot develop, therefore there is no possibility of mold and algae growth in substrates such as plaster, wood, paint, or any type of coating.
Temperature. The reproduction speed of microorganisms is influenced by temperature. Low temperatures slow it down, while temperatures between +20°C and +35°C create optimal conditions for rapid growth.
Nutrients. In addition to water, mold requires nutrients such as nitrogen, carbon, phosphorus, etc. These substances can be found in different substrates or deposited with dirt or atmospheric dust.

Based on the above, it is evident that mold and algae can grow and spread on both the internal walls of buildings and external surfaces, causing hygienic and aesthetic problems. Situations in which mold and fungi formations occur inside buildings:

Lack of thermal insulation with a drop in the "dew point" on the internal liminal surface and the formation of surface condensation.
Lack of air ventilation leading to an increase in the concentration of water vapor and condensation formation in colder areas (thermal bridges).
Rooms with high vapor production (kitchens, bathrooms) or where specific processes take place (laundries, industrial laundries, etc.).

SOLUTION: Standard Cycle - Internal rooms affected by modest presence of mould

CYCLE		INDICATIVE QUANTITY OF MATERIAL PER SQM
1	Treatment with a brush-applied BIOCID solution, ready to use waste, ready to use. After at least 24 hours from the application proceed to the mechanical cleaning of the surfaces. The formulated can be applied both on pre-painted and non-painted supports.	10 SQM/L
2	Completely remove any layers of old paints that adhere poorly or flake off. Clean and remove any traces of dirt, dust and treatment residues.
3a	Perform any filling on plaster or painting supports with LAMPOSTUCCO in powder or paste.	1 / 0.9 KG/SQM FOR 0.3 MM THICKNESS
3b	Perform any filling on plasterboard supports with KARTOFÜLLER smooth finish powder filler.	0.9 KG/SQM PER MM THICKNESS
4	Apply a coat of transparent water-based wall fixative MUFFANÒ PRIMER based on resin and anti-mold additives for the preservation of the dry film.	10 - 15 SQM/L (UNDILUTED)
5a	SANEX WASHABILITY 4 - COVER 2 Apply two or more coats of breathable and mold-resistant paint.	6 - 8 SQM/L PER COAT
5b	ACRYLSANA WASHABILITY 2 - COVER 2 Apply two or more coats of water-repellent, breathable, highly mold-resistant paint.	8 - 10 SQM/L

SOLUTION: Intensive Cycle - Rooms affected by a strong presence of mould

CYCLE		INDICATIVE QUANTITY OF MATERIAL PER SQM
1	Treatment with BIOCID solution applied with a brush to refuse, ready to use. After at least 24 hours from the application, proceed with the mechanical cleaning of the surfaces. The formulation can be applied on both pre-painted and unpainted substrates.	10 SQM/L
2	Completely remove any layers of old paint that are poorly adherent or flaking. Clean and remove any trace of dirt, dust, and treatment residues. In case of high concentrations of mold, repeat the treatment.
3a	Make any patching on plaster or painted surfaces with LAMPOSTUCCO in powder or paste.	1 / 0.9 KG/SQM FOR 0.3 MM THICKNESS
3b	Make any patching on drywall surfaces with KARTOFÜLLER powder stucco for smooth finishes.	0.9 KG/SQM PER MM THICKNESS
4	Apply a coat of transparent water-based wall fixative MUFFANÒ PRIMER based on resin and anti-mold additives for the preservation of the dry film.	10 - 15 SQM/L (UNDILUTED)
5a	MUFFANÒ WASHABILITY 1 - COVERAGE 3 Apply two or more coats of super-washable interior paint, highly resistant to mold growth, MUFFANÒ.	9 - 11 SQM/L PER COAT
5b	TERMOCASA WASHABILITY 3 - COVERAGE 3 Apply two or more coats of anti-condensation, thermal insulating interior paint, with hollow glass microspheres, highly resistant to mold growth, TERMOCASA . Particularly suitable in case of mold caused by condensation and/or thermal bridge.	3 - 5 SQM/L PER COAT
