For pipes, radiator paint is often considered the best paint option, particularly for pipes that may experience heat.
While various paints can be used, paints specifically designed for radiators are formulated to withstand heat without discolouring over time. According to the reference, radiator paint is "probably best" for pipes because "Some paints don't like the heat and discolour over time."
Why Choose Radiator Paint?
Radiator paint is engineered for high temperatures, making it ideal for pipes that carry hot water or steam, such as central heating pipes connected to radiators.
- Heat Resistance: Prevents paint from cracking, peeling, or discolouring when heated.
- Durability: Often formulated to be tough and resistant to minor bumps or abrasions.
- Aesthetics: Available in various finishes (like satin or gloss) and colours to match your decor.
Alternatives for Certain Pipes
For pipes that don't get hot, such as cold water pipes or certain types of copper pipes, you have more flexibility. The reference states, "You don't need oil based paint for copper pipes, primer and top coat as you would your woodwork (satin or gloss) is perfectly ok and will last."
This suggests that a standard painting process involving a suitable primer followed by a top coat designed for interior woodwork or metal can be perfectly acceptable for pipes like copper pipes, offering good durability and finish.
Here's a simple comparison:
| Paint Type | Best For | Key Benefit | Consider If... |
|---|---|---|---|
| Radiator Paint | Hot pipes (heating, hot water) | Heat resistance | Pipes get warm or hot. |
| Standard Primer + Top Coat | Cold pipes, some copper pipes | Versatility, aesthetics | Pipes remain at room temperature. |
Painting Process for Pipes
Regardless of the paint type chosen, proper preparation is key for a lasting finish.
- Clean: Ensure pipes are free from dirt, grease, and rust.
- Sand: Lightly sand the surface for better paint adhesion.
- Prime: Apply a suitable primer, especially important for metal pipes to prevent rust and ensure the top coat adheres well.
- Paint: Apply your chosen top coat (radiator paint or standard paint), following the manufacturer's instructions for coats and drying times.
Choosing the right paint based on the pipe's function (hot or cold) ensures a durable, attractive finish that won't deteriorate prematurely.
