INTERIOR OR EXTERIOR? 7 THINGS TO KNOW BEFORE YOU PAINT
BUILD SMART WITH RAYNEAU
Building Better Starts Here.
Last week, our Paint Series focused on one of the most important lessons in painting:
Prepare the surface before you paint it.
This week, we move to the next big decision.
Which paint should you actually buy?
Because choosing paint is about more than picking a colour you like.
The wall location matters.
The amount of sunlight matters.
Moisture matters.
Traffic matters.
The type of surface matters.
And most importantly:
Interior paint and exterior paint are not the same thing.
Before you head to the store, here are 7 things to know before you buy paint.
1. KNOW WHERE THE PAINT WILL BE USED
The first question should always be:
Is this surface inside or outside?
Interior paints are designed for indoor living spaces.
Exterior paints are made to deal with harsher conditions such as:
Sun
Rain
Heat
Humidity
Wind
Changing temperatures
Using the wrong type of paint can lead to early failure.
Build Smart Tip
Start with the location before you start with the colour.
2. THINK ABOUT SUN AND WEATHER EXPOSURE
An exterior wall that receives strong afternoon sun has different needs from a shaded bedroom wall.
Outdoor surfaces face:
UV exposure
Rain
Moisture
Heat
Weather changes
That means durability matters.
For exterior areas, choose paint designed to handle outdoor conditions.
The prettier colour means very little if the finish does not hold up.
3. CONSIDER MOISTURE AND HUMIDITY
Some rooms naturally deal with more moisture than others.
Think about:
Bathrooms
Kitchens
Laundry areas
Utility rooms
Exterior walls exposed to rain
In these areas, moisture resistance becomes important.
The same applies outside in Saint Lucia’s warm, humid conditions.
Before painting, ask:
Will this surface regularly deal with moisture?
If yes, choose a product suited to that environment.
4. THINK ABOUT HOW MUCH WEAR THE SURFACE GETS
Not every wall gets treated the same.
A quiet bedroom wall may experience very little contact.
A hallway, kitchen, child’s room or stair area may be touched constantly.
That means some spaces need paint that can better handle:
Cleaning
Fingerprints
Scuffs
Repeated contact
General wear
High-use areas need practical finishes, not just attractive colours.
This is one reason choosing the right paint finish matters too.
We will look at that more closely on Wednesday.
5. MATCH THE PAINT TO THE SURFACE
Paint does not perform the same way on every material.
You may be painting:
Concrete
Plaster
Drywall
Wood
Metal
Previously painted surfaces
Bare masonry
Different surfaces may require different preparation, primers or paint systems.
That is why it is important to know what you are painting before you buy.
The right paint begins with the right surface information.
6. DECIDE HOW EASY THE SURFACE SHOULD BE TO CLEAN
Some walls need to be easy to wipe down.
For example:
Kitchens
Bathrooms
Hallways
Children’s rooms
High-traffic areas
Other spaces may not need the same level of washability.
This is where finish becomes important.
Flat, eggshell, satin, semi-gloss and gloss finishes can behave differently when it comes to appearance, durability and cleaning.
Do not choose finish by appearance alone.
Choose it based on how the space will actually be used.
7. DO NOT LET COLOUR BE YOUR ONLY DECISION
Colour matters.
Of course it does.
But it should not be the first and only question.
Before choosing the shade, ask:
Interior or exterior?
What surface am I painting?
Is the area damp?
Does it get strong sun?
Will it need regular cleaning?
Is the surface high traffic?
Does it need primer?
Once you answer those questions, then choose the colour.
That is the smarter order.
INTERIOR PAINT VS EXTERIOR PAINT: KEEP IT SIMPLE
Here is an easy way to remember it.
Interior Paint
Best suited for indoor living spaces where comfort, appearance, cleanability and finish matter.
Exterior Paint
Best suited for outdoor surfaces where weather resistance, durability and protection matter more.
One paint does not fit every job.
ASK THESE QUESTIONS BEFORE YOU BUY
Before you head to RCIP, make a quick checklist:
Where am I painting?
Inside or outside?
What surface is it?
Concrete, plaster, wood, metal or something else?
What conditions will it face?
Sun, rain, humidity, cleaning, traffic?
What finish makes sense?
Flat, eggshell, satin, semi-gloss or gloss?
Does the surface need primer first?
If you know these answers, choosing paint becomes much easier.
THIS WEEK’S BUILD SMART RULE
MATCH THE PAINT TO THE PLACE.
Do not start with the colour card.
Start with the job.
The right paint in the right place will usually perform better, look better and last longer.
This Wednesday, we take the next step with:
Flat, Eggshell, Satin, Semi-Gloss or Gloss?
We’ll break down the different finishes and show where each one works best.
