Yes, you must either apply an oil primer or a primer that enables the transition from alkyd to latex paint. It is also important to adequately prepare the surface to allow for proper adhesion of the primer to the existing paint.
Perform a small test by taking a clean, neutral coloured rag moistened with rubbing alcohol or nail polish remover and gently rub the surface. If the surface in which you rubbed has not changed in colour and your rag has no trace of colour on it, you have an oil-based paint. However, if the surface has changed in colour and the rag is stained then you possess a latex paint.
A basecoat primer is not always necessary, but it is recommended, it favours better adhesion and guarantees the quality of your final result. In a case where you are applying a similar colour to your project, you can sand to remove the luster without using a primer.
Drying time varies depending on the colour, type of paint and atmospheric conditions. In some cases, it may take up to 60 days until the paint is completely and thoroughly dry. It is strongly recommended to allow at least 15 days before attempting to clean or wipe the painted surface.
Yes, and to save any remains you must: leave the paint in its original container, wipe the edges off of any paint, tightly seal with the lid and place the container upside down, preventing any air from infiltrating and forming any paint skin that normally forms when contents is exposed to air.
No. The paint will dry on the surface but not underneath. In order to ensure a uniform coverage, it is recommended to apply two regular coats.
It is best to sand before and between applying coats to ensure proper adhesion and added durability of the paint. Sanding is strongly recommended before applying paint to new wood or a painted, glossy surface, to reinforce the paint’s adhesion.
You must remove the masking tape when the paint is still partially wet to avoid damaging your painted surface.
The ceiling first, walls second, door and window frames last.
Yes, provided that sanding is performed prior to applying the paint, to ensure the best adhesion.
This may be due to the fact that a necessary base coat primer was not applied.
