Frequently Asked Questions:
General Paint Knowledge
Why does paint change colour when it dries?
As paint dries, it can seem to shift in colour for a few reasons. A major factor is the evaporation of solvents or water, which changes how it looks. Lighting is also crucial! The concept of Illuminant Metamerism illustrates how colours can appear different under various lighting, whether it’s the warm glow of natural sunlight or the cool tones of artificial light. This effect is especially prominent with shades like greys, taupes, and lavenders, which are quite sensitive to lighting variations.
What makes some paints washable and others not?
The washability of paint hinges on its formulation, especially the kind of binders and additives incorporated. Washable paints usually feature top-notch binders, like acrylic polymers, which form a resilient film that stands up to water and stains. Additives such as thickeners and surfactants boost the paint’s ability to withstand scrubbing and cleaning.
How does temperature affect how paint dries?
Temperature is a key player in the drying game of paint. When it gets too hot or too cold, it can throw a wrench in the drying process. For instance:
- High temperatures can make paint dry way too fast, which might lead to problems like cracking, peeling, or a bumpy finish.
- Low temperatures can drag out the drying time, leaving the paint sticky for longer and possibly causing poor adhesion or an uneven look.
It’s best to paint when conditions match the manufacturer’s recommendations, usually within a comfy temperature range. For Universal Paints, keeping the paint stored and applied between 15.5°C and 26.5°C is perfect for ensuring it dries and cures just right
Why do some paints have a strong smell while others don’t?
The distinct scent found in certain paints mainly comes from volatile organic compounds (VOCs). These are substances that evaporate into the atmosphere as the paint dries, giving off those noticeable odours. Solvent-based (oil-based) paints typically contain higher levels of VOCs, which is why they tend to have a stronger smell. In contrast, water-based paints, like acrylics, have lower VOC levels and thus produce less odour.
Universal Paints provides low-VOC and lead-free paint choices, making them a healthier option for indoor air quality and the planet. If you’re sensitive to paint smells, opting for low-VOC or water-based paints is a fantastic choice.
What’s the difference between oil-based and water-based paint?
Oil-Based Paints: These are made with organic solvents like mineral spirits, which means they take a bit longer to dry. They’re super durable, making them perfect for woodwork, trim, and metal surfaces. Just a heads up, they do have a strong smell because of the higher levels of volatile organic compounds (VOCs), and you’ll need solvents for clean-up.
Water-Based Paints: Often referred to as latex or acrylic paints, these use water as their solvent. They dry quickly, have a low odour, and are a breeze to clean up with just water. They work wonderfully for both interior and exterior walls, ceilings, and any surfaces where you want a fast-drying time.
Which type of paint is best suited for South Africa’s climate?
South Africa’s diverse climates—from coastal humidity to the dry Highveld—require paints that can withstand various environmental conditions. Universal Paints offers weather-resistant coatings designed to endure harsh elements, maintaining the structural integrity and visual appeal of homes and building.
How do I choose the right colour palette for my home?
Selecting the perfect colour palette for your home requires a few thoughtful considerations to achieve a cohesive and inviting aesthetic:
Natural Light: The intense sunlight in South Africa can really enhance colours. It’s a great idea to test paint samples on your walls and observe them at various times throughout the day to see how they respond to natural light.
Trend Insights: Neutral shades such as warm greys, gentle creams, and greiges (grey-beige) are trending for interiors. If you want to add a pop of colour, think about accent walls in rich terracotta or deep blues. For exteriors, earthy hues and off-whites are preferred as they harmonize with the natural surroundings and help reflect harsh UV rays.
Colour Tools: Universal Paints boasts an extensive selection of standard colours along with thousands more from the NCS Colour System. Bring in a swatch of a colour you adore, and our experts can mix and match it for you while you wait.
Professional Advice: If you’re feeling uncertain, reaching out to a professional interior designer or a colour consultant at Universal Paints can help you blend your personal style with considerations like architectural design and the environment.

Painting Techniques & Application
What is the recommended surface preparation and painting technique?
To achieve a long-lasting and professional finish, it’s crucial to focus on proper surface preparation and painting techniques. Here’s a handy guide to get you started:
Surface Preparation:
Clean the Surface: Clear away dirt, grease, peeling paint, and mould. A gentle detergent or sugar soap works wonders for cleaning.
Sand and Fill: Sand down glossy areas to create a textured surface for better paint adhesion. Use a suitable filler to patch up any cracks or holes.
Priming: Don’t skip the primer! It’s especially important for porous surfaces like fresh plaster or bare wood. Check out Universal Paints for top-notch primers like the Universal Undercoat.
Painting Techniques:
Cut-In Edges: Grab an angled brush to tackle those tricky edges and corners that rollers can’t reach.
Roller Application: Use a “W” motion with your roller to apply paint, then fill in the spaces for a smooth finish.
Number of Coats: Typically, two coats of topcoat paint are ideal. If the surface is in rough shape or you’re making a bold colour change, three coats might be the way to go.
Follow Manufacturer Guidelines: Stick to the drying times and application instructions for the best results.
How many coats of paint are really needed for full coverage?
For optimal coverage, it’s usually best to apply two coats of topcoat paint. However, if you’re dealing with surfaces that are in rough shape or making a significant colour shift, you might need to go for three coats. Remember to stick to the manufacturer’s recommended drying times between coats—generally, that’s about 2–6 hours for water-based paints and 6–24 hours for solvent-based ones.

Why does paint bubble or peel after application?
Paint can bubble or peel after application for a variety of reasons:
Insufficient Surface Prep: If the surface isn’t cleaned properly, it can lead to poor adhesion. Make sure to remove dust, grease, or any old peeling paint before you start with the new coat.
Wrong Priming: Skipping primer or using the incorrect type can lead to inadequate coverage and adhesion. Primers are key for sealing the surface and creating a solid base for your topcoat.
Environmental Factors: Painting under unsuitable conditions, like high humidity, extreme temperatures, or direct sunlight, can cause the paint to dry too quickly or too slowly, resulting in issues like blistering or peeling.
Application Technique: Applying paint too thickly or unevenly can lead to bubbles or peeling. Keeping a wet edge and applying consistent pressure is essential for achieving a smooth finish.
Can I mix different types of paint together?
Mixing two different types of paint—such as oil-based and water-based (acrylic), or even different brands or formulations within the same base type—can lead to a range of problems.
Here’s why you should avoid mixing incompatible paint types:
- 🧪 Chemical Incompatibility
Different binders and solvents:
– Oil-based paints use mineral spirits or turpentine and dry through oxidation.
– Water-based paints (acrylic or latex) use water and dry through evaporation.
These chemical differences mean they don’t blend properly. Instead of forming a uniform mixture, they can separate, curdle, or form clumps, much like oil and water. - 🎨 Poor Adhesion and Durability
Mixed incompatible paints may not bond well with each other or with the surface, leading to:
– Peeling
– Cracking
– Flaking
– Bubbling
These issues might not appear immediately but can surface weeks or months later, especially under environmental stress (e.g., moisture, heat). - 🎭 Unpredictable Colour and Finish
Different pigments, sheens (e.g., matte, gloss), and opacities can clash when mixed:
– The final colour may be muddy or dull.
– You could end up with uneven gloss levels.
– Inconsistent texture or application issues may arise (e.g., brush marks, poor flow). - 🧂 Stability and Shelf Life Issues
Mixed paints can:
– Separate quickly in the can
– Become gel-like or gritty
– Develop mould or spoil, especially if the mix disrupts preservatives

How do I fix paint streaks or roller marks on walls?
To tackle those pesky paint streaks or roller marks on your walls, just follow these simple steps:
- Surface Preparation: Make sure your wall is clean and dry. Sand down any bumps or ridges left by previous streaks.
- Use Quality Tools: Choose top-notch brushes and rollers, like Hamilton’s Brushware, for a flawless finish.
- Apply Primer: If the streaks are really stubborn, think about applying a primer to create a smooth canvas. Universal Paints has fantastic Primers for this.
- Proper Technique: When you’re ready to repaint, use the “W” technique with your roller for even coverage. Be careful not to overload the roller with paint.
- Lighting Check: Paint in bright, natural light so you can catch any imperfections right away.
- Final Touches: Let the paint dry completely between coats, and don’t hesitate to add a second coat if you need full coverage.
Can I paint over glossy surfaces without sanding?
It’s not the best idea to paint over glossy surfaces without sanding, as the paint might not stick well. To achieve a beautiful and lasting finish, it’s important to prep the surface by gently sanding it with fine-grit sandpaper (180–220 grit) to reduce the shine and create a texture for the new paint to adhere to.
Once you’ve sanded, make sure to clean the surface thoroughly to get rid of any dust or leftover particles. Using a high-quality primer, like the Universal Undercoat, is key for ensuring proper adhesion and a durable finish.
How can I address damp or moisture issues before painting?
To tackle damp or moisture challenges before you start painting, here’s a handy guide:
Identify the Source: Pinpoint and resolve the root cause of the dampness, whether it’s rising damp, roof leaks, or condensation from inadequate ventilation.
Use Damp-Sealing Products: Once repairs are made, apply a top-notch damp-proofing solution or penetrating sealer to keep future moisture at bay. Check out our selection of waterproofing products.
Allow Surfaces to Dry Completely: Make sure all surfaces are fully dry and cured, ideally for at least 48 hours under the best conditions, before you dive into painting.
Ventilation and Insulation: Boost airflow with vents or extractor fans and think about adding insulation to reduce condensation, particularly in humid spots.
Surface Preparation: Give the surface a thorough clean to eliminate debris, and consider using a sealer to stabilize any porous or chalky areas.
Durability & Longevity
What makes paint fade over time?
The fading of paint over time is mainly due to UV radiation from sunlight, which breaks down the pigments and binders in the paint. Other contributors include environmental conditions such as humidity, temperature changes, and pollution, which can wear down the paint’s structure. Plus, using lower-quality paint or not prepping the surface properly can speed up the fading process.
To help reduce fading, think about using high-quality, UV-resistant paints like those from Universal Paints. Proper surface prep and applying a good primer can also boost durability.
Why does some paint crack after a few years?
Over time, paint can develop cracks for a variety of reasons:
Inadequate Surface Preparation: If the surface isn’t thoroughly cleaned or primed, the paint might struggle to stick, leading to cracks as time goes on.
Environmental Conditions: Extreme temperatures, high humidity, or direct sunlight during application can interfere with proper drying or curing, which can cause cracking.
Type of Paint Used: Oil-based paints are more susceptible to cracking (alligatoring), while latex paints might show smaller cracks (checking) due to their drying characteristics.
Application Issues: If paint is applied too thickly or unevenly, it can create drying issues that lead to cracks.
Aging of the Surface: Older surfaces that have been exposed to the elements may need extra preparation to avoid cracking.
To fix cracks, sand down the affected area, apply a primer, and choose a high-quality, flexible paint like latex for lasting results.
How long does paint actually last in a sealed can?
The lifespan of paint in a sealed can varies based on the paint type and how it’s stored. Typically:
Water-based paints can remain good for 2–3 years with proper storage.
Oil-based paints can last even longer, up to 5–10 years, when kept in ideal conditions.
To maximize their shelf life, keep your paint in a cool, dry spot and ensure the lid is tightly sealed to keep out air. If you’re uncertain about your paint’s condition, look for separation, lumps, or any unpleasant odours before using it.
What’s the best way to clean painted walls without damaging them?
To keep your painted walls looking fresh without causing any harm, try these steps:
Dust First: Grab a soft, dry cloth or a duster to gently whisk away loose dust and dirt from the wall surface.
Spot Test: Before diving into cleaning the whole wall, test your cleaning solution on a small, hidden spot to make sure it won’t damage the paint.
Use Gentle Cleaners: Blend a mild detergent with warm water. Steer clear of harsh chemicals or abrasive cleaners that could strip the paint.
Soft Tools: Opt for a soft sponge or microfiber cloth to delicately clean the walls. Avoid scrubbing too vigorously, especially on matte or flat finishes.
Rinse and Dry: Once you’re done cleaning, wipe the wall with a clean, damp cloth to eliminate any soap residue, and then dry it off with a soft towel.
Can paint be removed completely without damaging the surface?
Completely stripping paint without harming the surface hinges on the paint type and the surface material. Here are some handy techniques:
Sanding: Grab some fine-grit sandpaper (like 180–220 grit) and gently sand away the paint from surfaces such as wood or metal. This approach works well but be cautious to avoid scratching the surface.
Heat Gun: For enamel or oil-based paints, a heat gun can be your best friend, softening the paint for easy scraping without the need for harsh chemicals. Always make sure you’re in a well-ventilated space and use a scraper to lift the paint.
Rubbing Alcohol: If you’re dealing with latex or water-based paints, rubbing alcohol is a great option. Just apply it with a cloth or sponge and gently rub the surface. This method is safe for wood, glass, and mirrors.
Paint Strippers: For those stubborn oil-based paints, you might need a solvent-based paint stripper. Be sure to follow the product instructions closely and ensure good ventilation, as these products can be flammable.
