Question 1

What grit sandpaper should I use between coats of paint on trim and cabinets?

Accepted Answer

For sanding between coats of paint on trim and cabinets, 220-grit sandpaper is the standard — it is fine enough to smooth without cutting through the paint layer. This step is what separates a truly smooth professional finish from one that looks slightly rough when you look at it from an angle in raking light.

The purpose of sanding between coats is not to remove the previous coat — it is to knock down any raised grain, dust nibs, brush marks, or minor drips that dried in the first coat. When y

Question 2

How do I prevent brush marks when painting trim and doors in my Fredericton home?

Accepted Answer

Brush marks on trim and doors come down to three things: paint consistency, brush quality, and technique — and all three are fixable. In Fredericton's dry winter heating season, latex paint can dry so quickly that brush marks freeze in place before the paint has time to level. Knowing how to work with these conditions makes a significant difference.

Start with the right brush. For trim and door painting, you want a high-quality synthetic bristle brush — 2.5 inch (63 mm) for most trim, 3 inch (7

Question 3

How do I clean and store paint brushes and rollers between coats and between painting sessions?

Accepted Answer

For latex paint, rinse brushes and rollers in warm water immediately after use — never let paint dry in your tools. Proper cleaning between coats takes only a few minutes but extends the life of good brushes considerably, saving you money and giving you better results every time.

Between coats of latex paint, you do not need to fully clean your brush or roller if you are coming back within 1-2 hours. Wrap your brush tightly in plastic wrap or a plastic bag, pressing out any air, and set it hori

Question 4

What is the W or M technique for rolling paint on walls and does it really matter?

Accepted Answer

Yes, the W or M technique genuinely matters — it is the difference between patchy, uneven coverage and a smooth, professional-looking finish. Rolling randomly up and down in straight lines leaves lap marks and uneven paint distribution. The W/M technique ensures the paint is spread and blended before it dries.

The technique works like this: load your roller evenly on the tray, then apply the paint to the wall in a large W or M shape covering roughly a 60-90 cm (2-3 foot) square section. Do not

Question 5

How do I spray paint exterior siding with an airless sprayer on my NB home?

Accepted Answer

Spraying exterior siding with an airless sprayer is fast and produces excellent coverage, but it requires thorough masking, proper tip selection, and ideal weather conditions — all of which matter even more in New Brunswick's unpredictable Maritime climate. Done right, it cuts painting time dramatically. Done wrong, it creates overspray damage, uneven coats, and a finish that fails early.

Before you even load the sprayer, preparation is everything. Cover all windows, doors, light fixtures, and

Question 6

How do I use a paint edging tool versus cutting in freehand with a brush?

Accepted Answer

Paint edging tools — the plastic-wheeled pad applicators you find at hardware stores — are convenient for beginners but rarely produce as clean or fast a line as freehand cutting with a good angled sash brush once you have practised. They are worth understanding, though, because for certain specific situations they are genuinely useful.

A paint edger (the most common version is a flat pad with a row of small guide wheels along one edge, sometimes called an Edger Pad or Cut-In Tool) works by run

Question 7

What is the proper technique for loading a paint roller for even coverage?

Accepted Answer

Loading a paint roller properly — distributing paint evenly through the nap before it touches your wall — is the foundation of every smooth, streak-free paint job, and most DIY painting problems trace back to a roller that is either over-loaded with dripping wet paint or under-loaded and dragging dry on the surface. The correct technique takes about 60 seconds but transforms your results.

Start with a quality roller tray — not a flimsy disposable one that flexes and tips, but a sturdy metal or

Question 8

How do I avoid roller marks and streaks when painting large wall areas in my Moncton home?

Accepted Answer

Roller marks and streaks almost always come from one of four causes: a dry roller, wrong nap thickness, paint that is drying too fast, or not maintaining a wet edge — and all four are completely avoidable with the right technique. Large walls in Moncton homes, especially open-plan living areas and long hallways, are the most challenging because you have more surface to cover before the paint begins to tack.

Start with a properly loaded roller. Pour paint into your tray and work the roller throu

Question 9

What painters tape is best for clean lines and how long can I leave it on before removing?

Accepted Answer

For clean lines on interior walls and trim, FrogTape Multi-Surface (green) gives the sharpest edges of any tape available in NB hardware stores — its paint-blocking technology seals the edge against bleeding far better than standard blue tape. Remove it while the paint is still slightly tacky — ideally 1-4 hours after your final coat — rather than waiting until the paint is fully cured.

Most homeowners reach for the familiar blue 3M ScotchBlue painter's tape, which is a solid general-purpose ta

Question 10

How do I cut in around ceilings and trim without using painters tape?

Accepted Answer

Cutting in freehand — without tape — is the technique professional painters use on the job because it is faster, gives a sharper line once mastered, and avoids the bleed-through issues that tape can cause on rough or textured surfaces. The key is using the right brush, the right paint loading technique, and a steady, controlled stroke.

The essential tool is a quality 2.5 inch angled sash brush — Purdy XL or Wooster Alpha are favourites among NB painters. The angled tip is what makes freehand cu

Question 11

Should I use an airless sprayer or brush and roller for painting interior walls in my NB home?

Accepted Answer

For most NB homeowners painting their own interior walls, brush and roller is the right choice — it is more forgiving, requires far less prep work, and produces excellent results on typical wall surfaces. An airless sprayer is faster in professional hands but demands extensive masking, creates significant overspray, and has a steep learning curve.

Brush and roller advantages are significant for a typical Moncton or Fredericton home interior. A quality 10mm (3/8-inch) nap roller covers wall surf

Question 12

What is back-rolling and should I always do it after spraying paint on walls?

Accepted Answer

Back-rolling means following a spray application immediately with a dry or lightly loaded roller to press the atomised paint into the surface, remove any sags or uneven texture, and improve adhesion — and yes, you should almost always back-roll interior spray applications on walls and ceilings. It adds a small amount of time but dramatically improves the quality and longevity of the finish.

When an airless sprayer deposits paint on a wall, the atomised droplets land on the surface but sit sligh

Question 13

What is the best paintbrush brand and type for cutting in around trim in a New Brunswick home?

Accepted Answer

For cutting in around trim, the best brushes available in New Brunswick are Purdy XL Glide (2.5 inch angled sash) and Wooster Shortcut — both are professional-grade brushes that give clean, sharp lines and hold an edge beautifully with latex paint. The right brush makes the single biggest difference in cut-in quality, and it is the one place in a painting project where spending $20-30 on a quality brush versus $8 on a discount brush is completely worth it.

The key is an angled sash brush, also

Question 14

What roller nap thickness should I use for different surfaces when painting walls and ceilings?

Accepted Answer

Roller nap thickness — also called pile or nap length — is matched to surface texture: smooth surfaces need short nap (6-10mm), standard drywall walls need 10mm (3/8 inch), and rough or textured exterior surfaces need 15-20mm (5/8 to 3/4 inch). Getting this right is one of those small details that separates a professional-looking result from a frustrating, uneven one.

Smooth surfaces — cabinets, interior doors, trim, and furniture — need a 6mm (1/4 inch) micro-fibre roller or foam roller. The s
