Interior walls

Walls: New - Where Walls Have Numerous Hairline Cracks Or Areas Where Trowel Marks Are Evident:

Ensure that the condition of the substrate is sound e.g. cement plaster is not friable.
Brush down all dust and loose material on raw plaster.
If moisture is below 15% apply one coat of PROMINENT PROMODEK, PROMINENT FILLERCOAT or PROMINENT WALL PRIMER.
Remove all plaster spatter and spot prime over these areas with above-mentioned in point 2.
Fill holes/cracks (other than hairline cracks) with PROGOLD READYMIX CRACK FILLER (4 hours drying time). Spot prime over fillers with PROMINENT DAMPCURE (24 hours drying time).

Sand down well with 80 Grit sandpaper and remove all residue with a soft bristle broom. NO FURTHER patching or filling to be done once the spot priming is done:

Apply one coat of PROMINENT PREMIUM TEXTURED at 4-5m² per litre (6 hours drying time).
Apply one or two final coats of superior acrylic PVA e.g. PROMINENT PREMIUM SATIN or PROMINENT PREMIUM SHEEN at 5m² per litre (6 hours drying time between coats).
There is the alternative choice of applying one coat of PROMINENT RIPPLE COURSE, PROMINENT RIPPLE COARSE or PROMINENT RIPPLE SMOOTH, PROMINENT RIPPLE TROWEL ON or PROMINENT TEXTURE CRETE over the walls prepared as in points 1-4 to obtain a textured finish/effect on the walls.

Walls: Previously Painted–Plastered And Painted With Acrylic:

Determine the condition of the surface and what type of paint was previously applied. Check all walls with a moisture meter before painting. If moisture content is above 15% check and remedy the cause of the moisture ingress, then

Sand down with 80 Grit sandpaper and wipe off residue.
Before filling cracks, spot prime in cracks with PROMINENT DAMPCURE 24 hours drying time) fill cracks with PROGOLD READYMIX CRACK FILLER (drying time depends on thickness of application).
Spot prime over PROGOLD READYMIX CRACK FILLER with PROMINENT DAMPCURE and when dry, measure for moisture. If below 15% then:
Apply two coats of superior quality PVA e.g. PROMINENT PREMIUM SATIN, PROMINENT PREMIUM SHEEN or PROMINENT PREMIUM MATT (6 hours drying time between coats).

OR If excessive moisture is evident, determine the cause of the moisture and remedy, then

Sand down damp area with 100 Grit sandpaper to remove all previous paint coatings and fillers to original plaster substrate.

Apply two coats of PROMINENT DAMPCURE (24 hours drying time). Do a further moisture check and if moisture is below 15% then:

Apply two coats of PROMINENT PREMIUM SATIN, PROMINENT PREMIUM SHEEN or PROMINENT PREMIUM MATT (6 hours drying time between coats).

If moisture persists above 15%, apply a further coat of PROMINENT DAMPCURE and check for moisture at regular intervals. When the moisture content drops to 15%, only then can a final coat be applied i.e. PROMINENT PREMIUM SATIN, PROMINENT PREMIUM SHEEN or PROMINENT PREMIUM MATT.

Walls: New – Cement Plastered:

Where walls are sound and moisture content is 15% or less:

Remove all plaster spatter and brush down surfaces with a soft bristle broom.
Apply one coat of PROMINENT WALL PRIMER, PROMINENT PROMODEK or PROMINENT FILLERCOAT (6 hours drying time).
NB: In bathroom and kitchen areas, apply one coat of PROMINENT DAMPCURE at 5m² per litre to walls and ceilings (24 hours drying time).
Apply two coats of superior quality PVA e.g. PROMINENT PREMIUM SHEEN, PROMINENT PREMIUM MATT, PROMINENT ULTRA SHEEN or PROMINENT ULTRA MATT.

Remove all plaster spatter and brush down surfaces with a soft bristle broom.
In case of poor quality plaster with insufficient amount of cement apply one coat of PROMINENT SURFACE RESTORER (24 hours drying time).
Apply two coats of superior quality acrylic PVA e.g. PROMINENT PREMIUM MATT, PROMINENT PREMIUM SHEEN, PROMINENT ULTRA MATT or ULTRA SHEEN (6hours drying time between coats).

Bathroom and kitchen Where moisture content is below 15%

Apply one coat of PROMINENT DAMPCURE (24 hours drying time).
Apply two coats of PROMINENT ULTRA SHEEN or PROMINENT ULTRA GLOSS (24 hours drying time between coats) i.e. kitchen, bathroom walls.
Apply two coats PROMINENT PREMIUM EGGSHELL ENAMEL/PROMINENT PREMIUM NON DRIP ENAMEL to shower area (24 hours drying time between coats).

Where walls are sound and moisture is less than 40%:

Remove all plaster spatter and brush down surfaces with a soft bristle broom.
Check on firm plaster surfaces for signs of dampness, apply one or two coats of PROMINENT DAMPCURE (24 hours drying time) and re-check moisture content on walls. Wait until moisture drops to 15%.
Where moisture is below 15%, apply two coats of superior quality acrylic PVA e.g. PROMINENT PREMIUM MATT, PROMINENT PREMIUM SHEEN, PROMINENT ULTRA SHEEN or PROMINENT ULTRA MATT (6 hours drying time between coats).
WALLS: PLASTERED – PREVIOUSLY PAINTED WITH AN OIL BASED PAINT

Where moisture content is below 15%:

Sand down with 80 Grit sandpaper and remove residue.
Open up any cracks/holes. Before filling with PROGOLD READYMIX CRACK FILLER, spot prime in crevices/holes with PROMINENT DAMPCURE (24 hours drying time), fill with PROGOLD READYMIX CRACK FILLER (drying time is dependant on wet film thickness).

Apply one coat of PROMINENT DAMPCURE over the fillers (24 hours drying time). Retest for moisture over the fillers, if below 15%, then:

Wash down walls with a PROGOLD G.P. CLEANER/Water solution, ratio 1:6, using a 3M Scotchbrite Pad Medium. Rinse off surfaces with clean water.
Check wall surface to ensure that the entire wall has been keyed by the sanding process.
Apply two coats of PROMINENT PREMIUM EGGSHELL ENAMEL, PROMINENT PREMIUM NON DRIP ENAMEL or PROMINENT ULTRA SHEEN at between 6-8m² per litre using a Mohair type roller.

Apply two coats of PROMINENT PREMIUM SHEEN at 6m² per litre (first coat) and 8m² per litre (second coat) (6 hours drying time between coats).

Apply two coats of PROMINENT ULTRA SHEEN at 6m² per litre (first coat) and 8m² per litre (second coat) (6 hours drying time between coats).

Walls: Previously Painted - Where Walls Have Numerous Hairline Cracks Or Areas Where Trowel Marks Are Evident:

Determine the condition of the surface and what type of paint was previously used.
Fill holes/cracks (other than hairline cracks) with PROGOLD READYMIX CRACK FILLER (4 hours drying time). Spot prime over fillers with PROMINENT DAMPCURE (24hours drying time).
Sand walls and patched areas lightly with 80 Grit sandpaper and remove all residue with soft bristle broom. NO FURTHER patching or filling to be done after spot priming is done:
Apply one coat of PROMINENT PREMIUM TEXTURED at 4-5m² per litre (6 hours drying time).
Apply one or two final coats of superior quality acrylic PVA e.g. PROMINENT PREMIUM SATIN/PROMINENT PREMIUM SHEEN at 5-7m² per litre or PROMINENT ULTRA MATT/ ULTRA SHEEN at 6-10m² per litre (6 hours drying time between coats).

There is an alternative choice of applying one coat of PROMINENT RIPPLE COARSE OR PROMINENT RIPPLE SMOOTH over the walls prepared as in points 1-3 to obtain a textured finish/effect on the walls.

Walls: New – Plastered With Glass Stone/Rhinolite/Cretestone:

Test all surfaces with a moisture meter. If moisture is 15% or less, then:

DO NOT SAND DOWN before applying one coat of PROMINENT PLASTER PRIMER (24 hours drying time) or PROMINENT DAMPCURE (24 hours drying time).
Ensure to inspect the PROMINENT PLASTER PRIMER and PROMINENT DAMPCURE applications to ensure that the RHINOLITE and CRETESTONE and GLASS STONE is fully covered as failing in doing so will cause delaminating of final coats.
Sand down lightly with 100 Grit sandpaper and remove residue.
Apply two coats of superior quality acrylic PVA e.g. PROMINENT PREMIUM MATT, PROMINENT PREMIUM SATIN or PROMINENT PREMIUM SHEEN (6 hours drying time between coats).
