HOW MUCH PAINTING MATERIAL DO I NEED?-LCETED



HOW MUCH PAINTING MATERIAL DO I NEED?

LETS US CONSIDER

We have 20 x 10 ft new wall to paint

Let’s Calculate Materials For This Wall

STEP 01: FIND ITS AREA

Total Area = Length X Breadth

Total Area = 20 x 10 = 200 sq/ft

STEP 02: FIND QUANTITY OF PUTTY

The standard coverage of wall putty in

2 COATS IS 14 -16 SQFT/KG.
3 COATS IS 8 - 12 SQFT/KG.

So the calculation of estimation of wall putty count area of the wall and divide it's to 14/15/16.

Therefore,

Our area is 200sqft divide is by 15

= 200/15

= 13.33 =14kg

STEP 03: FIND QUANTITY OF PRIMER

Wall Primer covers 120 - 140 square feet per litre in one coat, whereas it covers 90-100 square feet per litre in two coats.

Therefore,
We will paint one coat of primer for this wall

So for 200 sqft wall = 200 / 120 = 1.67 litres – 2 litres

STEP 04: FIND QUANTITY OF PAINT

Interior paints usually termed Emulsions have coverage of about 80–100 sqft in 2 coats per litre.
Exterior paints, typically have a coverage of 40 sqft in 2 coats per litre.
Therefore,
We need to paint 200 sqft wall of an interior wall (we consider as interior wall)

So litre of paint we need 200/80 = 2.5 – 3 litre of paint we need to paint

RESULT
FOR 200 SQFT OF WALL WE NEED

14KG OF PUTTY

2 LITRES OF PRIMER

3 LITRES OF PAINT
