It would be challenging to locate a home that a good paint job couldn’t improve. To keep them looking good for a long time, however, all paint works require regular maintenance and preparation before the painting even begins. Older homes are more prone to these problems than relatively new homes, which may experience paint problems.
Since everything has a shelf life, the paint in an older house will eventually require replacement. Some decorative problems, such as peeling paint or cracked plaster, might be difficult to solve, especially if you’re in the middle of a significant DIY undertaking.
To help you decorate your home like a pro that to with budget friendly and EMI scheme, PaintMyWalls, best painters in Bangalore, has listed the most common paint problems and how to fix them. If you’re about to pick up a paintbrush, be sure to carefully read them before doing so.
- Chalking
On painted walls, a loose-based powder called “chalking” forms. Low-quality paints with a lot of pigment extenders are to blame for this common paint problem. Other crucial factors include the painting’s age, colour, and technique. Some intensely tinted or bright colours may quickly become chalky. Paint that has been thinned out too much could also become problematic.
Solution: The stray paint can be removed by scraping. Paint over blemished areas and fill in empty spaces. Apply premium paints following the suggested rates for spreading and thinning. When using vibrant colours, it is best to use the highest-quality paint you can.
- Blistering
If you notice bubbles coming through the base coat of the wall paint, that is blistering. Blisters are caused by the moisture being drained from the surface where the paint is applied. Painting during periods of high humidity, painting a damp surface, or repainting too soon can all cause it. Insufficient surface preparation further increases the possibility of blisters.
Solution: Steer clear of painting when the humidity or dew point is high. Make sure the surface is dry and moisture-free before painting. Give the surface enough time to cure before repainting it. If the blisters go deeper than the skin’s surface, moisture becomes a problem. The installation of vents and exhaust fans in the affected areas is strongly advised in this circumstance. Selecting the proper primer undercoat for the type of surface to be painted will give you the best chance of success—and may even mean the difference between success and failure.
- Mould/Mildew
Surface growth of patches that are black, grey, brown, and green in colour identify a fungus as mould/mildew. Mould and mildew like to grow in areas with a lot of moisture, inadequate ventilation, and little sunlight. Low-quality paint’s inability to adequately protect against mould and mildew increases the likelihood of growth.
Solution: Scrub the affected area with household white vinegar to get rid of mould spores. Apply a coat of stain-resistant primer. Avoid using inexpensive acrylic or oil-based alkyd paint, and instal exhaust fans in areas with a lot of moisture to ensure proper ventilation.
- Peeling
On interior and exterior surfaces, peeling paint with some curl to it is a frequent issue. Although poor preparation and application can contribute to peeling, moisture is the main enemy.
Excessive moisture inside the house may result from high humidity in the basement and/or foundation, but it is also possible that overzealous cooking, showering, and humidifier usage habits are to blame. Peeling on the exterior of the house can be caused by poor caulking, clogged gutters, a leaky roof, or interior moisture that seeps through exterior walls. Paint that is applied to a damp surface or siding that is less than six inches above the ground may also peel.
Solution: Peeling paint should be removed before repainting any exterior issues like loose shingles, overflowing gutters, or crumbly caulking. Use the exhaust fans, wall vents, and/or louvres to enhance interior ventilation as necessary.
- Alligatoring
Alligatoring, which may be the most inventive term for a paint issue, describes a pattern that genuinely resembles reptilian skin. It begins as minor checking that gradually widens into rectangular cracks. With oil-based paints especially on texture or designers walls, alligatoring tends to be more prevalent. Temperature changes cause paint to naturally expand and contract, and over time, loss of elasticity can lead to alligatoring. Mistakes like painting over a glossy finish (the topcoat does not bond properly to the glossy finish), not allowing enough dry time between the primer/basecoat and topcoat, or applying a rigid coating like oil enamel over a softer, more flexible coat (like latex paint or latex primer) can speed up the process.
Solution: By sanding, scraping, applying chemical removers, or using a heat gun, remove unsightly scales. After that, rinse to remove any dust, and allow to fully dry. Prime, let dry and then repaint.
- Efflorescence
On a pretzel, salt crystals that are crusty and white might be appealing, but not on the painted masonry of your house. When the salts found naturally in brick, concrete, cinderblocks, and mortar dissolve in moisture and then reach out to the surface, a condition known as efflorescence (also known as mottling) develops.
Several elements, such as inadequate curing time for cement or mortar during construction, moisture migration from the interior of the home, groundwater intrusion from a poorly waterproofed basement, inadequate surface preparation to remove previous efflorescence, and painting over holes, cracks, or unrepaired pointing, among others, all contribute to efflorescence.
Solution: On a warm, dry day, deal with efflorescence. By waterproofing and repairing cracks, repointing, and sealing around windows and doors with butyl rubber caulk, you can get rid of excessive moisture conditions outside.
Using a wire brush, scraper, low-pressure washer, or cleaning with dilute white vinegar or a trisodium phosphate (TSP) solution (wear protective gear when working with this chemical) and then thoroughly rinsing are some methods for removing efflorescence, and you may need to combine them depending on the extent and severity. A building material’s surface can be sealed with an impregnating hydrophobic sealant to stop moisture from penetrating and prevent water from soaking through. Coatings made of silicone or acrylic as well as colourless water repellents may stop the recurrence of efflorescence. Prior to repainting, let the surface dry completely.
- Cracking/Crazing
Cracking is the separation of a dried paint film through at least one coat. It’s also possible that when the second coat was applied, the first coat wasn’t entirely dry.
Solution: Sand the damaged area with fine-mesh sandpaper and use the appropriate primer layer before repainting with high-quality paint at the recommended spreading rate.
