Painting your guttering can be a great way to improve the exterior of your home. Guttering is often overlooked, but it can have a big impact on the curb appeal of your property. Gutters are usually made from materials such as steel, aluminium, or plastic, and each of these surfaces requires different treatment when it comes to painting. For example, aluminium gutters can be painted with either oil-based or acrylic paints, but it's important to avoid paint that contains ammonia. Plastic guttering can be painted, but it's important to prepare the surface properly, using sandpaper to dull the shine and help the paint adhere. It's also worth noting that modern plastic gutters are designed to last for up to 25 years without the need for any painting or treatments.

Cleaning plastic guttering before painting
Before painting plastic guttering, it is important to clean and prepare the surface. This will ensure that the paint adheres properly and that you achieve a long-lasting and aesthetically pleasing finish. Here is a step-by-step guide to cleaning plastic guttering before painting:
- Clear any leaves, debris, dirt, or other build-up from the gutter. You can use a hose to remove debris from the interior of the gutter and a scrub brush or stiff-bristle brush to clean the exterior.
- Wash the gutter with mild detergent, lukewarm water, and a soft-bristled brush to remove any remaining dirt, grime, or grease. Ensure that the surface is thoroughly cleaned to prevent anything from clinging to the gutter and affecting the paint adhesion.
- If there is any peeling or chipping paint on the gutter, use a plastic knife, filling knife, or stiff-bristle brush to carefully remove it. Avoid using metal tools that could damage the plastic surface.
- Rinse the gutter again with clean water to remove any soap residue.
- Allow the gutter to dry completely before proceeding to the painting stage. Check the weather forecast and ensure you have enough time for the gutter to dry in dry conditions.
- If there are any cracks or holes in the gutter, they should be repaired before painting. Clean and dry the area around the crack, then apply a waterproofing sealant with a paintbrush, smoothing it out as much as possible. Allow the sealant to dry for several days before painting.
- If you want to remove the gutter or loosen the screws for easier access during painting, ensure that you are confident in your ability to reinstall the gutter securely.
By following these steps, you will effectively clean and prepare your plastic guttering for painting, ensuring a smooth and durable finish.

Choosing the right paint for plastic guttering
Painting plastic guttering can be a laborious job. Before you start, it is important to understand the surface you are painting. Gutters are pipes that drain water from the roofline and are made of a range of materials, including steel, aluminium, and plastic, which impacts how they are painted.
If you are looking to paint your plastic guttering, you will need to prepare the surface by cleaning it with soapy water and a degreasing agent to achieve a residue-free surface. You can also use sandpaper to dull the shine on the plastic and help the paint adhere better. It is also recommended to use a primer to help the paint adhere and achieve an aesthetically pleasing finish. Some paints are self-priming, like Zinsser Allcoat Exterior, which can be applied to almost any exterior surface and can be mixed in almost any colour. However, if your paint is not self-priming, you will need to buy a separate primer and apply two coats of paint.
It is important to note that some paints may not adhere well to plastic, so it is recommended to buy gutters with built-in UV protection to avoid the need for painting altogether. Modern plastic gutters are manufactured to last for up to 25 years without the need for any painting or treatments. If you are set on painting your plastic gutter, it is recommended to use a gloss paint, as gloss has more oil in it and can better cope with the expansion and contraction of the plastic. You can also use 100% acrylic paint, but it is not recommended to use an undercoat as it is too brittle for plastic.
If you are also painting metal gutters, you will need to sand them down and prime them before painting. You should strip off any remaining paint and use sandpaper or a sanding tool to create a smooth surface. You should also repair any holes before moving on to the next stage. It is important to use a paint with anti-rust properties, like Rust-Oleum Combicolor Metal Paint, to maintain a pristine finish and reduce the amount of prep work required.

Using a primer for plastic guttering
Before you start painting your plastic guttering, it is important to clean and prepare the surface. Clear any debris and scrub the guttering with soap and water. If your guttering is particularly dirty, you can use a detergent or a mixture of detergent and water. Ensure that the guttering is completely dry before moving on to the next step.
Next, use a plastic putty knife to scrape off any old paint. Apply paint stripper to a rag and scrub off any remaining paint spots. Wear gloves and a face mask during this process to protect yourself from the fumes. Sanding your guttering will ensure that it is completely smooth before you apply primer and paint.
Now, you can apply a primer to your plastic guttering. Priming is important as it helps the paint adhere to the surface. You can use a paintbrush or an airless sprayer to apply the primer. Ensure that you apply a thin but even coating across the surface of the guttering. If you are using a water-based paint, you will need to use a synthetic-bristle paintbrush, whereas a natural-bristle paintbrush is best for oil-based paint.
If you are using an oil-based paint, you should use an oil-based primer. Similarly, if you are using a water-based paint, you should use a water-based primer. You can also use a self-priming paint such as Zinsser Allcoat Exterior, which can be applied to almost any exterior surface, including plastic. This paint is available in gloss, satin, and matt finishes and can be mixed in a wide range of colours.
It is important to note that you should always check the weather forecast before starting your project to ensure that you have enough time to complete it in dry conditions. Working at heights can be dangerous, so always practice good ladder safety and, if possible, work with a partner who can spot you.

Removing plastic guttering before painting
Removing plastic guttering can be a challenging task, but it is necessary if you want to ensure a thorough paint job. Here is a step-by-step guide on how to remove plastic guttering before painting:
Examine the Guttering System: Before starting the removal process, it is important to understand how your guttering system is attached to the roof. Guttering can be screwed, nailed, or riveted in place, so identify the type of hardware used. This will determine the tools you need for the removal process.
Clear Debris and Clean the Gutters: Start by removing any leaves, dirt, or debris from the gutters. Then, use a mild detergent or lukewarm water to scrub the gutters clean. This step is crucial as it ensures that the paint will adhere properly to the surface.
Remove Downspouts First: To avoid unnecessary weight and potential damage, it is recommended to remove the downspouts first. Downspouts are usually attached to the gutter pieces and can be heavy, so removing them first will make the process safer and more manageable.
Loosen Screws or Nails: If your gutter is attached with screws, use a screwdriver to loosen and remove them. If it is nailed in place, use a hammer or a pry bar to carefully remove the nails. For riveted guttering, you may need to drill out the rivets before proceeding.
Detach the Guttering: Once the screws, nails, or rivets are removed, you can carefully detach the guttering from the brackets or mounting hardware. In some cases, you may need to use a flat-head screwdriver to pry the guttering away from the clips or straps that hold it in place. Be cautious and wear gloves to protect yourself from sharp edges.
Fill Holes and Smooth Surfaces: After removing the guttering, you will likely be left with holes or imperfections on the surface. Use caulk or wood putty to fill these holes, depending on the type of surface. Smooth the patched areas with your finger or a putty knife, and consider painting over them for a uniform appearance.
Remember that removing guttering can be a challenging task, and it is important to prioritize your safety. Always use a stable ladder and consider having a partner assist you during the process. Additionally, be cautious of sharp edges and wear appropriate protective gear.

The best colour for plastic guttering
When it comes to the best colour for plastic guttering, it is subjective and depends on your house's colour scheme. The go-to choice is usually a shade that matches the rest of the exterior trim, such as fascias and soffits.
White has been a common and popular colour choice for guttering in the UK since the 1970s. However, modern shades such as black, grey, and anthracite grey are also popular. Black guttering tends to be the most popular colour choice for homeowners and is available in PVC or aluminium. White and grey are also available in both materials.
If you are looking for something different, bespoke colours are available for aluminium guttering. These can improve the aesthetics and create a lovely finish. Bespoke colours range from Signal Red to Pearl Night Blue.
It is worth noting that plastic gutters tend to discolour, become brittle, and leak. After a few years, they can look very faded, which can devalue the property's value and overall look. Therefore, if you are looking for guttering that does not require regular maintenance and will retain its finish for decades, aluminium guttering may be a better option. Aluminium guttering can be powder-coated to any RAL colour to match any colour scheme and will not rust, rot, or become brittle like plastic guttering.
