How Much Paint do you need?
How Much Paint do you need? Use the easy steps below to determine the right amount of paint to purchase: 1. Measure the perimeter of your room (length and width). Add all 4 numbers together. 2. Multiply the perimeter by the height. 3. Deduct windows and doors. An average window is approximately 1.5m2 and an average door is 2.5m2 4. Divide by 14. Top Tip Length + Length + Width + Width = Total Perimeter Always round up to ensure that you have enough paint to complete the job. The PASCOL table below isPAINT a guide to the number of FOR litres required REQUIRED WALLS per coat. Actual usage ONE will vary depending COAT ONLYon application technique, surface textureofand porosity.

Wet areas like Kitchens, Bathrooms and Laundries need a more serviceable paint to resist steam, moisture and cooking stains.

Some have unique qualities for specific substrates or surfaces and are available in water based or oil based formulas. Using a high-quality Wattyl preparatory product ensures maximum adhesion and an even finish with more accurate colours. It’s easy with Wattyl. It can actually save you time and money too!

The great majority of paint failures are attributed to inadequate surface preparation. 1 3 2 1. It is essential that the surface to be painted is clean and dry. 2. Be sure to repair any surface imperfections/ damage. • • Gaps and seams: Fill all cracks and seams with paintable acrylic gap sealer. Prime the area. • Holes: Fill all holes with patching compound and sand smooth. Prime the area. • Removal of dirt, dust and grease: Clean surface with a cleaner such as household detergent and water or sugar soap (if greasy or heavily soiled) and rinse thoroughly. Glossy surfaces: Sand glossy surfaces until dull with sandpaper to promote adhesion. 3. Peeling Paint Scrape or sand to completely remove any peeling paint. Feather sand to a smooth edge and remove dust. Prime the area.
