paint primers are used before painting to prepare the substrate for a more even finish coat. This subcategory includes a 1:4 acrylic primer concentrate for outdoor and indoor work.
What paint primers are used for
- helping prepare porous areas before applying finish paint;
- improving paint adhesion to a prepared substrate;
- reducing the risk of uneven coating application on mixed or absorbent surfaces;
- preparing substrates outdoors and indoors under the conditions stated by the manufacturer;
- forming a layer that is transparent after drying when the substrate colour should remain visually unchanged.
How to choose a primer before painting
- for painting preparation, check acrylic primers compatible with the selected finish coating;
- a 1:4 concentrate is chosen when a working solution diluted with clean water is needed;
- smaller packs suit local jobs, while larger volumes are more convenient for bigger areas;
- if the substrate is porous or uneven, consider absorbency and the condition of the old coating;
- before buying, check application temperature, application method and dilution recommendations.
What to check before priming
- the substrate should be dry, solid and cleaned of dust, dirt, grease, old coating residue and poorly bonded particles;
- the concentrate is diluted with clean water in the ratio stated for the specific product;
- after dilution, apply the solution evenly with a brush, roller, paintbrush or spraying;
- work should be done at the temperature stated in the product specifications and with regard to site conditions;
- finish paint is applied after substrate preparation and drying of the primer layer according to the instructions.
