Surface preparation:

Old surface preparation:

• Remove the loose particles,dust,dirt,grease,wax,mortar dropping
  and growth of fungus,algae,dampness,etc. With the help of wire brush
  or putty knife.
• Rubbed the old surface thoroughly with sandpaper. Wash the whole
  surface and leave for drying.
• Fill the holes and cracks (up to 3mm) with the putty or gypsum and
  leave for hardening.
• Sand the wall with the sandpaper to make a smooth surface and wipe
  off the dust with the dry cloth.

New surface preparation:

If you want to paint a newly plastered wall,allow it to cure completely. As the manufacturer recommends to allow 28 days as
curing time for new masonry. However, allow moisture to dry completely 3 to 6 month period desired depending upon local climate where there is high humidity.

• Remove the loose particles, dust, dirt, grease, wax, mortar dropping, and growth of fungus, algae, dampness etc. With the help of
  wire brush or putty knife.
• Wiped off the dust with the dry cloth.

Drying Time :

The drying time for acrylic distemper depends on factors like:
1. Thickness of application
2. Temperature
3. Humidity
4. Air circulation
5. Surface porosity

Typical drying times for acrylic distemper:
1. Surface dry: 30 minutes to 1 hour
2. Touch dry: 1-2 hours
3. Hard dry: 2-4 hours
4. Complete cure: 24 hours

Please note that these times are approximate and may vary depending on the specific conditions. It’s essential to allow the recommended drying time between coats and before exposing the painted surface to water or heavy wear.

Coverage:

The coverage of NeoCoat acrylic distemper varies depending on factors like:
1. Surface texture and porosity
2. Thickness of application
3. Color and finish
4. Type of surface (plaster, cement, wood, etc.)

Typical coverage for acrylic distemper:
1. Smooth surfaces: 120-150 square feet per liter (sf/l)
2. Semi-smooth surfaces: 100-120 sf/l
3. Rough surfaces: 80-100 sf/l
4. Textured surfaces: 60-80 sf/l

To calculate the required amount of NeoCoat acrylic distemper:
1. Measure the surface area to be painted (length x width)
2. Choose the appropriate coverage rate based on the surface type
3. Divide the surface area by the coverage rate
4. Add 10-20% to account for uneven application and waste

Example:
Surface area: 1000 square feet
Coverage rate: 120 sf/l (smooth surface)
Required distemper: 1000 / 120 = 8.33 liters (add 10% = 9.17 liters)
Remember to consult the manufacturer’s specifications for specific coverage rates and application guidelines.
