How to paint external vinyl surfaces with latex paint ?

Although manufacturers advertise vinyl siding as not requiring special care, over time the finish may fade or the color scheme may become outdated. Whether you're choosing a new color to freshen up old vinyl or update the look of your home, purchase the right paint and prepare the siding and trim for paint application to ensure the durability of the coating.



Repair

Inspect all vinyl surfaces for loose panels, connecting elements, damage or rusty metal elements. Replace pieces of vinyl that have serious or non-repairable damage, such as holes or tears. Tighten all loose joints, make sure that all siding panels and decorative trim are securely fastened. Remove and replace metal bolts or fasteners that are heavily rusted, or clean them of surface rust.



Clearing

A clean surface is necessary for the paint to fit snugly to the vinyl. Painting over dirt or mold will leave unsightly bumps under the paint and allow it to peel off easily. To remove dust and dirt, spray the vinyl with a pressure washer. If there is grease, chalk residue or mold, remove them with detergent and a soft nylon brush. Do not use brushes that can scratch the vinyl, such as wire brushes or steel wool. Rinse off the detergent and let the vinyl dry completely before painting.



Paint selection

Vinyl expands in heat and contracts in cold, so it needs a paint that can stretch and contract without delaminating and losing adhesion. Choose a paint for outdoor work that consists entirely of acrylic latex, and not from a mixture of other paints. Latex adheres tightly to smooth vinyl surfaces and remains flexible enough to withstand expansion and compression under temperature fluctuations. Choose a color that is close to the existing one or lighter than it. Painting vinyl in a darker color can cause it to attract excess heat and deform.



Painting

Vinyl can be sprayed or painted with a roller and brush, as well as wood trim and siding. Choose a day when the temperature is above 1.5 degrees and there is no wind. Work as much as possible in the shade and avoid painting vinyl that is heated to the touch from exposure to direct sunlight. Fasten with tape all the areas that will not be painted, or completely cover them with a mask if you use a spray gun. Priming vinyl siding is optional. Apply a thin coat of paint, let it dry for four hours, and then apply a second coat. lvov.natashaescort.com/en/
