Safety Precaution

  • When working with paints or chemicals, make sure you wear a face mask and gloves.

Washing the Gutters

Using Pressure Washer

  • Use a pressure washer to clean debris – Start by cleaning off dirt and debris on the gutters.
  • With its extendable arm, a power washer makes the task of cleaning the gutters very easy.
  • Use a ladder for better reach – To get closer to the drains, use the ladder
  • Fix the damaged gutters – Ensure your gutters aren’t loose or severely rusted before power-washing them to avoid potential damage
  • Rinse – Do thoroughly rinse the drains using the power washer, ensuring you get rid of dirt, flaking paint and any other debris.

Using Soap As An Alternative to the Power Washer

  • If you don’t have a power washer, you can use soap and water to clean the gutters. Use two tablespoons of mild soap for every eight glasses of water
  • Ensure you stand beneath the drains on a ladder to apply the paint well
  • Scrub using a brush with soft bristles or a horsehair brush
  • Unfortunately, this method will take more time than if you used a power washer
  • to remove the gutters and scrub them from the ground
  • To make it easy for you to fix them back, ensure you label from which part of the house you removed them

Cleaning Mildew

  • You can use the mildew retardant to remove the mildew from the gutters
  • Note that retardants contain chemicals that remove mould and inhibit it from forming
  • Apply the retardant as instructed on the label
  • The compound is dangerous to inhale, so you are well advised to wear a face mask and gloves when using it.

Air Drying the Gutters

  • Always clean gutters on a sunny day. After you have cleaned them, allow them between four and six hours to dry.
  • To drain the water from the cracks and crevices, flip them over every now and then.

Stripping, Sanding, and Sealing

Use a Plastic Putty Knife to Strip Off Old Paint

  • The plastic putty knife is ideal as it does not leave scratch marks on the metallic gutters as would a wire brush.
  • Use long strokes and apply pressure as you remove the old paint on the gutters.
  • Ensure you remove as much old paint as you possibly can.

Use Stripping Chemicals to Remove Old Paint

  • Sometimes, the old paint is caked onto the gutters, so it is hard to remove it. Apply stripping chemicals to make it easier to remove the paint.
  • Apply a bit of paint stripper on a rag and rub off the old paint
  • The paint stripper chemicals are dangerous to inhale, so use as little amount as possible
  • Always wear a face mask and gloves to protect yourself from the stripper chemical fumes

Use Sanding Block to Smoothen the Surface

  • Use the sand block to remove rough patches as well as any remaining old paint.
  • Sanding helps the new paint to adhere better to the gutters
  • You could save more time if you used a palm sander
  • Take your time to ensure the drains are as smooth as possible

Rinse the Gutters

  • Use a pressure hose or a wet cloth to remove residue from sanding
  • Ensure the gutters feel smooth to the touch

Use a Cloth to Dry the Gutters

  • Ensure that there is no residue from sanding the gutters or water from washing.
  • Before you prime the gutters, make sure they are completely dry

Use a Gutter Seal to Seal the Joints

  • To seal the gutter joints and downspout connections, apply the gutter seal
  • Allow the gutter seal to dry before priming the gutters
  • Skip this step if your gutters have no joints

Protect Your Home From Paint with Cardboards

  • Put small pieces of cardboard below the gutters to prevent the paint from pouring into your fascia and soffits.
  • You can use painter’s tape to fasten the cardboard below the gutters
  • Ensure your home’s soffits, siding and fascia are covered away from the primer being applied to the gutters

Alternatively, Remove the Gutters and Paint them on the Ground

  • Remove the gutters using a screwdriver if you are not comfortable painting them when they are attached to the fascia
  • Lay them on a painter’s tarp in your yard
  • Make sure they are correctly labelled to make it easy to put them back
  • Go ahead and prime and paint them on the ground where you are sure the paint will not get into your home

Use Oil-Based Prime to Prevent Rusting

  • Ensure the prime is specially manufactured for use on the gutters
  • Ask your professional painter to give you recommendations of the best primer for gutters in your area
  • The primer helps the top coat of the paint to stick better on the gutters, thus preventing peeling or flaking

Use an airless Spray Quick Application

  • Use the airless spray to get value for money
  • If you use a sprayer, mask the fascia and the roof to prevent over spraying.
  • Wipe off the paint that gets to unwanted places
  • Apply the light coat by adjusting the pressure knob on your sprayer
  • Wear a respirator mask to keep the fumes from the sprayer at bay

Use a Brush or a Roller if You Don’t Have an Airless Sprayer

  • Use the traditional roller or a paintbrush as an alternative to an airless sprayer
  • Never over-apply the primer, as this makes it hard for the top coat to be applied evenly
  • If you used an oil-based primer, allow it one to two hours to dry
  • The label on the primer will give you the preferred wait time until it dries
  • Never apply the top coat until the primer is completely dry

Applying the Paint

Use Oil-Based Paint for Outermost Layer

  • To protect the gutters from water damage, use gloss or satin paint for the top coat.
  • The oil-based paint dries faster and has a better finish
  • Research the best oil-based paint for gutters available in your area

Ensure the Paint Colour Complements Your House’ Colour

  • Most homeowners prefer white for gutters as it looks clean. It is a good colour, especially if you have painted your house’s exterior walls black
  • For homes with grey or brown exteriors, you may opt to paint your gutters similar colours to blend in

Use a Paint Brush or Sprayer to Apply a Thin Top Coat

  • A brush helps you evenly spread the top coat on the gutters
  • If there are any runs from using the brush, correct them immediately
  • If you are in a hurry, you can still use the sprayer to apply the thin top coat, but you will need to adjust your pressure knob
  • If you use the sprayer, only spray the top layer once to prevent the paint from getting thick

Allow the Paint to Dry

  • The top coat will take two to four hours to dry completely
  • If you are lucky, you will be using fast-drying paint, and you won’t have to wait this long
  • To ensure the colour appears even, you can apply another top coat with a paintbrush or a paint sprayer

Put Back the Gutters if You Were Painting Them From the Ground

  • Fix the gutters back after the paint is completely dry

Make the Final Touch-ups on Missed Parts

  • If you spot any places you may have missed, use a small paintbrush to do the final touch-up
