**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

**200sqf**t 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**
