Estimating Paint Quantity and Cost For Your Home Renovations

Common paints on the market can be bought per gallon or 4 liters of paint. For instance, 1 gallon of Semi-Gloss Latex Paint covers 30 to 40 square meters surface area depends on the manufacturer.

To simplify, let us take as an example a concrete wall that measures 20 meters in length and 10 meters in height. The wall has a course to rough surface and we want to paint it with a Semi-Gloss Latex Paint.

What are the things that we will be needing:

1. Semi-Gloss Latex Paint- semi gloss or gloss latex paint are good because they are easy to maintain and does not attract dirts.

2. Concrete Primer -this is design to promote optimal paint and stain adhesion

3. Neutralizer - is a liquid acidic substance that is to be mixed with water to neutralize lime activity in new masonry surfaces

Now, how to compute for the quantity:

1. First we need to know what will be the total area of the wall we want to paint. This is done by multiplying the walls's length by it's height:

Wall Area 

= Length x Height

= 20 meters x 10 meters

= 200 square meter

2. To get the total quantity Semi-Gloss Latex paint, we need to divide the wall's total area by the total area that 1 gallon of paint can cover. As mentioned above, 1 gallon of paint can cover a minimum of 30 square meter:

Total Paint Quantity 

= Total Wall Area / Paint Coverage per gallon

= 200 square meter / 30 square meter

= 6.67 or 7 gallons

3. To get the total quantity of concrete primer, same computation as above:

Total Concrete Primer Quantity 

= Total Wall Area / Paint Coverage per gallon

= 200 square meter / 30 square meter

= 6.67 or 7 gallons

4. To get the total quantity of Neutralizer:

Total Wall Area / Neutralizer Coverage per gallon

= 200 square meter / 30 square meter

= 6.67 or 7 gallons

If 1 quart of Neutralizer is mixed with 2.5 gallons of water so:

7 gallons of neutralizer / 2.5 gallons of water

Total Quantity of Neutralizer = 2.8 or 3 quartz

You can now estimate the total cost by multiplying total number of gallons by the market price per gallon. Example:

Total Paint Cost 

= 12 gallons x P 900.00 per gallon

= P 10,800.00 and so on
