⇒ There are four things you can do to help minimize brush marks and leave a smooth surface on your paint job:
1. Set your loaded brush down on a dry section of the wall – or the trim, or siding, or whatever you’re painting – and to lift it from a previously coated, still wet section.
2. Make sure your paint is the right consistency. Thicker paint holds marks more than thinner paint does. If you’ve left paint in a closed can overnight, it will dry out and thicken up a little. Thoroughly stir the paint and, if it seems too thick, add thinner sparingly – you don’t want to get it too thin. Stir it thoroughly and try it again.
3. The right brush and to make sure it is in the best condition. Oil-based paint, shellacs and varnishes should be applied with a china bristle brush.
4. Latex paint and stain should be applied with a good quality nylon/polyester brush. These are often labeled “for use with all paints.” Better synthetic filament brushes have more ‘flags’ – the splits at the end of each filament – and the filaments are round and solid, not flat or hollow. In other words, they more closely mimic real bristles. Good quality nylon/polyester brushes are only slightly less expensive than good china bristle brushes – say $30 for a 4″ sash brush, for example.
⇒ There’s also the issue of the cleanness of the brush. If a brush has not been thoroughly cleaned, all the way back into the ferrule, and the bristles and filaments combed straight and wrapped in a cover to dry, they may start to bond together into small spikes.
Handy Tips, Advices & Warnings
Removing paint on glass and windows
It is well known that dried paint can be removed from glass with a razor blade. If the glass objects are textured or uneven, soak them in water and dishwasher liquid for a few hours.
Doing clean touch ups
During light painting jobs, put a “Zip Lock” type sandwich bag in a plastic margarine tub and fold the bag edges over the rim. Pour the paint into the bag of your “paint tray” and once the job is over, remove the bag and seal it, or throw it away.
Giving old wood a fresh look
Exterior wood siding can be painted, or stripped and painted. Strip paint using a torch by burning the old paint and scraping it lightly being careful not to damage the wood. Clean the surface with trisodium phosphate (TSP), which you can find in the paint department of your local home renovation centre. Repair siding where needed and caulk. If you are repainting in the same colour, apply the finishing coat after the wood is dry. If you are changing colours, apply a primer coat followed by the new colour, using exterior paint (an oil based primer will be necessary if going from oil to latex). Avoid painting in full sun, at sunset, in the early morning, in the rain or in the wind. To keep bugs from sticking to the fresh paint, simply add two tablespoons of citronella to the paint.
Finishing product: paint, stain, varnish, etc.
Different customers have different needs. No product meets every need. To select the appropriate product, start by identifying your needs based on the following specific criteria in order to create a “funnel” leading to your ideal product. The product selection process is simple, effective and based on eight product selection criteria: function, environment, surface, use, composition, appearance, colour and quality.
Masking knots before painting
Knots in finished wood will appear sooner or later after painting. Before painting, seal the knots with a lacquer. It is the only liquid sealant that will efficiently seal in knot resin, without discoloring the finishing paint.
Choosing the right paint texture
Each paint finish has its own properties. The more matte the finish, the more it hides imperfections and uneven reflections, but it’s less washable. The glossier the finish, the more washable it is, but also the more sensitive to imperfections and it will mask less efficiently. In order: glossy, semi-gloss, pearl, eggshell, satin, matte. Semi-gloss is best for hall walls and for windows and frames; use matte on ceilings and satin and pearl for the rest. Kitchens, bathrooms and basements have their own antifungal paints.
Drying paint and the temperature
Paint in a ventilated and temperate space. When temperatures are between 10C and 32C there’s no risk, although 15c to 22C is ideal. Latex paint will dry in a few hours at this temperature. Oil-based paints will dry more rapidly in a warm, dry environment.
Shaking paint: inescapable…
When you buy paint, your retailer is always careful to mix it in an agitator. Old paint must also be shaken after the dried surface layer has been removed. The best “tool” to shake your old paint: a kitchen whip. Otherwise, any type of handle will do to stir in a figure 8, for a few minutes.
How much paint to buy
When it comes to calculating how many litres of paint to buy, remember that one gallon (3.78 litres) will generally cover 400 square feet. You can calculate the painted surface in square measure by multiplying depth by the width for ceilings and the height by the width for walls.
Acoustic Ceiling Cleaning
Acoustical tile ceilings act as “sponges” for sound, soaking up excess noise to create a more pleasant environment. Unfortunately, these tiles also absorb airborne dirt, grease, cigarette smoke, nicotine, and bacteria, making ceilings dirty. Professional cleaning solution can break down the dirt film into micro-dust particles that evaporate into the atmosphere and are filtered away through the air handling system.
