What Needs To Be Done Before Painting A House’S Exterior?

Before painting your exterior, it is essential to choose the right paint type, color, weather conditions, and tools. Homeowners should periodically inspect exterior paint jobs for signs of damage, as climate can affect the longevity of the job. For the best results, follow the tried and true painting techniques recommended by professionals. Woodwork is best painted using either a gloss or satin paint (Farrow and Ball’s Exterior Eggshell and Full Gloss), while brick and stone need to be painted.

HGTV.com shares 10 things you must know before starting a successful exterior paint job. Learn how to choose the perfect paint for the outside of your house with their guide on types, colors, and application techniques to boost curb appeal. This guide will explain how to prep for exterior painting whether you have wood, aluminum, or vinyl siding.

To prepare a house for exterior painting, remove contaminants, make any needed repairs, remove peeling paint, prime the walls, plan the outside building painting process, clean the exterior walls by washing them with water, remove flaking paint before building outside painting, sand, move and cover furniture, remove electronics and appliances, wall hangings and ornaments, protect soft furnishings, clear away knick-knacks, and clean the walls thoroughly.

Painting the siding first, starting at the top, painting horizontally as you work your way down. Use a scaffold if possible or move the ladder regularly.

In summary, before painting your exterior, it is crucial to choose the right paint type, color, weather conditions, tools, remove anything attached to the house, pressure wash the entire house, replace rotted siding or fascia boards, and follow the recommended painting techniques.

How to treat external walls before painting?

Before painting, ensure the wall surface is clean, dry, and grease-free. Remove loose paintwork, replace loose mortar or render, and fill and repair any cracks with exterior grade filler. If the surface becomes powdery, brush it down and treat it with a masonry stabilizing solution. Treat areas with fungal growth with a fungicidal wash or household bleach, followed by thorough cleaning. The wall color is linen wash, the window frame is loft white, the table is small, and the chair is bone china blue.

What should I clean my house with before painting?

Before deep cleaning your siding, spray off large debris and wet the entire surface with a moderately high-pressure tip, typically the green or yellow tip. Avoid using red tips (0-degree) as they can damage your siding. Stand back about ten feet to start, then move in closer for more impact. Apply more pressure as you get closer to the spray gun. Keep this pressure and distance in mind for step three. Use the same amount of pressure again and cover all areas to avoid missing spots. If you miss a spot, it will be visible.

Do I need to sand before painting the exterior?

Sanding is a common exterior and interior maintenance process to remove peeling paint edges and limit unsightly imperfections. It smooths out plaster, joint compound, or spackling, allows for “bite” between coatings, and reduces glossiness. However, it is advised to avoid sanding on homes built before 1978 with lead paint, as it should be done by a certified professional with the appropriate equipment. This is especially important for homes built before 1978.

Is it OK to use paint without primer?

Paint and primer in one is a high-quality paint that enhances adhesion and stain blocking capabilities. It is suitable for both interior and exterior projects, but not every project requires a specific type of primer. For instance, some surfaces like wood and metal require a primer for proper adhesion and blocking power, while vinyl and aluminum siding may need a specialty primer to handle the PH level.

Primers are necessary for various reasons, such as checking the surface’s sheen/gloss, dark color, rust or corrosion, and previous coating shape. Without a proper primer, adhesion may be lost, and surface contaminants may bleed through. Preparing a surface clean, dry, and dull is crucial.

The advantages of using paint and primer in one depend on the project, but it can save time and money by applying paint directly to the surface without priming. However, most products advertised as paint and primer in one may be more costly, and the project may also cost more if issues arise.

Some surfaces that may require a specialty primer include kitchen cabinets, interior woodwork, metal surfaces, cement, block, brick, or stucco, plaster walls, rust or corroded surfaces, very dark or bright colors, shiny surfaces, chalky surfaces, and raw wood. It is essential to analyze the project and consult a paint expert before purchasing products.

What is the best time to paint house exterior?

The spring and fall seasons are optimal for painting a house’s exterior, as temperatures range between 40 and 90 degrees Fahrenheit, providing favorable conditions for painting.

What is the best thing to wash walls with before painting?

Before painting a wall, it is essential to scrub the surface to remove dirt and debris. Avoid using harsh chemicals that can cause permanent damage. Instead, use warm, soapy water to gently rub the wall, starting from the base and working your way up. This will leave a smoother surface for paint application. If soap and water aren’t enough, create a DIY cleaning solution by adding distilled white vinegar to warm water.

Ensure the wall is spotless to prevent paint from sticking to the surface. For stubborn stains, use baking soda, a substance used to clean sinks and toilets, and apply it to the wall with a clean cloth. Dry the wall with a towel and wait for a few hours before applying paint or primer.

If trouble persists, try trisodium phosphate (TSP), a powerful wall cleaner. Wear safety goggles and rubber gloves when using TSP. Add a quarter cup of TSP to a bucket with hot water and apply the solution to the wall with a sponge. Use a second bucket for removing the cleaner from the surface.

What is a good cleaner before painting?

To clean interior walls before painting, follow these tips:

1. Stick with warm water or mild soap.
2. Use white vinegar or plain water for flat or matte paint.
3. Clean glossy paint with all-purpose cleaner or dish soap and water.
4. Use baking soda and water for white paint.
5. Use dish soap and water or vegetable oil-based cleaner for latex paint.
6. Use white vinegar or dish soap and water for oil-based paint.
7. Choose and gather necessary materials before starting the project to ensure a smooth and efficient job.

Can I paint over old exterior paint?

Before painting over old exterior paint, it’s crucial to assess the condition and type of the existing paint. If the paint is in good condition and adheres properly, a prime may not be necessary. However, if the paint is peeling, chalking, or flaking, it’s best to prime it before applying a new coat. Primer creates a smooth surface, promotes better adhesion between the old and new paint layers, and can block stains, especially if the old paint has water or rust stains.

What to do before painting an exterior house?

1. Pressure-wash walls to remove dirt and dust buildup.
2. Repair damaged surfaces, remove loose paint, caulk trim, prime stains, protect doors, windows, and lights, then paint the exterior and trim and doors.

Do I need to wash exterior walls before painting?

Before painting exterior walls, it is essential to clean them to ensure they are clean and dry. Dirt and debris on the wall can hinder the adhesion of paint to the surface. A step-by-step guide on how to paint exterior walls includes using Masonry paint, a long-pile paint roller, a paint tray or scuttle, a paint brush, sandpaper, dust sheets, masking tape, exterior filler, filling knife, and scraper. Proper preparation is crucial for achieving a high-quality finish or ensuring proper paint adhesion.

Is it necessary to prime before exterior painting?

Primer is crucial when removing old paint from surfaces before repainting them, as it fills in any cracks or imperfections left by the removal process and acts as a sealant to prevent moisture from seeping into the cracks and causing damage. If the old paint job is peeling off your house, primer is essential. Primer is especially important for bare wood, as it provides additional protection against moisture and prevents warping or cracking due to water damage over time. It also gives wood more vibrant colors when painted over, as natural oils in wood tend to dull when painted directly on top of them without primer.
