PAINTING INTERIOR WALLS

Determining your product requirements
Measure area to which paint is to be applied. Depending on surface to which the product is to be applied, determine which products are needed. Check the Theoretical Spread Rates (TSR) on each of the specified products and see how many coats of each are recommended, then calculate what quantities of each product you will require, remembering to make adjustments for the porosity of each surface. TSRs are based on products applied to smooth, sealed surfaces. (e.g. an unsealed scratch plaster surface will absorb more paint than a sealed smooth one, so allow for a lower spread rate). Check out the specifications on all the top coat choices (referring to the relevant data sheets) and decide which is right for you.TSR = Theoretical Spread Rate | NC = Number of Coats | DT = Drying Time
Interior Walls - Previously Painted with Acrylic
If Smooth Plaster previously painted in acrylicSurface PreparationRemove all loose peeling paint if any. Where paint has been removed, feather the edges of remaining paint to zero with sand paper. Remove sanding dust. Wash wall down to remove all dirt ,dust and any other contaminants. Allow to dry. Application MethodIf peeling paint has been removed exposing gypsum plaster then prime exposed gypsum plaster only with 1 or 2 coats RhinoSeal. Allow to dry between coats. If peeling paint has been removed exposing cement plaster then prime exposed cement plaster with 1 coat AcrySeal diluted 1:1 with water. Allow to dry. Prime all sealed plaster with 1 coat of AcrylUnder and allow to dry. Finally apply 2 top coats of your choice.Related Paintcor ProductsTSR = Theoretical Spread Rate | NC = Number of Coats | DT = Drying TimeUndercoat / PreparationRhinoSeal - TSR: 10 - 15m² per litre | NC: 1 – 3 Coats | AM: Brush, Roller or Spray | DT: 24 – 48 hours before overcoatingAcrySeal - TSR: 10 - 15m² per litre | NC: 1 Coat | AM: Brush, Roller or Spray | DT: @ 25°C – 30 minutesAcrylUnder - TSR: 5 - 6m² per litre | NC: 1 Coat | AM: Brush, Roller or Spray | DT: @ 25°C – 30 minutesTop Coat ChoicesEleganceMatt - TSR: 8 - 10m² per litre | NC: 2 Coats minimum | AM: Brush, Roller or Spray | DT: @ 25°C ±25 minutesEleganceSilk - TSR: 8 - 10m² per litre | NC: 2 Coats minimum | AM: Brush, Roller or Spray | DT: @ 25°C ±25 minutesEssensual - TSR: 8 - 10m² per litre | NC: 1 or 2 Coats | AM: Brush, Roller or Spray | DT: @ 25°C ±25 minutesEnviroCoat - TSR: 10m² per litre | NC: 1 or 2 Coats | AM: Brush, Roller or Spray | DT: @ 25°C ±30 minutesLuxuriance - TSR: 8 - 9m² per litre | NC: 2 Coats | AM: Brush, Roller or Spray | DT: @ 25°C ±30 minutesPristina - TSR: New Plaster: 4 - 5m² per litre.

Interior Walls - Unpainted
If new unpainted gypsum plaster (Rhinolite)Method #1: Using PlasterPrime (for good quality plaster only)Surface PreparationNew Gypsum Plaster (Rhinolite)Ensure gypsum plaster is dry and of good quality, i.e the surface is hard and free of chalk. Note: If the chalky powder remains after wiping, Paintcor’s RhinoSeal must be applied in place of PlasterPrime to ensure the complete binding of the chalking gypsum plaster. Wipe good quality gypsum plaster down to remove all dirt and dust. Application MethodApply 1 coat of PlasterPrime to all gypsum surfaces to be painted. Allow to dry for 6 hours @ 25oC. Overcoat within 7 days. Apply 2 coats of the top coat of your choice. Allow to dry between coats.Method #2: Using RhinoSeal (for chalking gypsum plaster)Surface PreparationWipe walls down to remove all dirt and dust Application MethodApply 1 coat RhinoSeal directly to gypsum plaster (RhinoLlite) wall with a brush, roller or airless spray. Allow 12 hours to dry. Check if substrate is properly bound ( i.e. no chalking gypsum plaster ) If necessary apply a second coat of RhinoSeal. Allow to dry. Allow 24 - 48 hours to dry before overcoating with AcrylUnder (for acrylic top coats) or UniSub (for enamel top coats) Apply top coats of your choice.Related Paintcor ProductsTSR = Theoretical Spread Rate | NC = Number of Coats | DT = Drying TimeUndercoat / PreparationPlasterPrime - TSR: 12 - 15m² per litre | NC: 1 Coat | AM: Brush, Roller or Spray | DT: @ 25°C – 6 hours.

Interior Walls - New Cement Plaster using PlasterPrime
If new cement plaster (using PlasterPrime)Surface PreparationEnsure plaster is dry and of good quality. Poor quality plaster (plaster that continues to release loose particles when brushed) must be sealed using Paintcor’s AcrySeal and not PlasterPrime. Application MethodApply 1 coat PlasterPrime to new plaster to be painted. Allow to dry for 6 hours @ 25oC. Overcoat within 7 days. Over coat with 1 coat of Paintcor’s AcrylUnder or SubTex (Use SubTex if there are texture differences on the new plaster) and 2 coats of the top coat of your choice. Note: Should a desirable finish be achieved after application of the PlasterPrime, simply over coat with 2 coats of the top coat of your choice.Where PlasterPrime Should Be Used:PlasterPrime should be used on all new good quality plaster only and especially after the application of Paintcor’s KlinkaSeal to stop rising damp.Please Note: AcrySeal must be used in place of PlasterPrime on poor underbound plaster.Related Paintcor ProductsTSR = Theoretical Spread Rate | NC = Number of Coats | DT = Drying TimeUndercoat / PreparationRhinoSeal - TSR: 10 - 15m² per litre | NC: 1 – 3 Coats | AM: Brush, Roller or Spray | DT: 24 – 48 hours before overcoatingAcrySeal - TSR: 10 - 15m² per litre | NC: 1 Coat | AM: Brush, Roller or Spray | DT: @ 25°C – 30 minutesAcrylUnder - TSR: 5 - 6m² per litre | NC: 1 Coat | AM: Brush, Roller or Spray | DT: @ 25°C – 30 minutesKlinkaSeal - TSR: 15m² per litre | NC: 2 Coats | AM: Brush, Roller or Spray | DT: @ 25°C – 30 minutesTop Coat ChoicesEleganceMatt - TSR: 8 - 10m² per litre | NC: 2 Coats minimum | AM: Brush, Roller or Spray | DT: @ 25°C ±25 minutesEleganceSilk - TSR: 8 - 10m² per litre | NC: 2 Coats minimum | AM: Brush, Roller or Spray | DT: @ 25°C ±25 minutesEssensual - TSR: 8 - 10m² per litre | NC: 1 or 2 Coats | AM: Brush, Roller or Spray | DT: @ 25°C ±25 minutesEnviroCoat - TSR: 10m² per litre | NC: 1 or 2 Coats | AM: Brush, Roller or Spray | DT: @ 25°C ±30 minutesLuxuriance - TSR: 8 - 9m² per litre | NC: 2 Coats | AM: Brush, Roller or Spray | DT: @ 25°C ±30 minutesPristina - TSR: New Plaster: 4 - 5m² per litre.
