Crown Trade PX4 All Purpose Primer

Crown Trade PX4 All Purpose Primer is a fast drying primer suitable for a wide range of surfaces, such as wood, masonry, metal, walls and ceilings. Can also be used on surfaces that are subject to staining by smoke, aerosol spray and tannin to help the decorative coat achieve a stain free finish.

To obtain superior results it is important to guarantee the area is structurally sound, clean and dry, being free of any flaws or imperfections

• Clean off any flawed, peeling and defective paint either by sanding or with the use of a paint scraper
• Extra care should be taken during the surface preparation of pre-1960s paint surfaces as they may contain harmful levels of lead
• Remove any organic growth, such as lichen, mould, algal or fungal growths, with an antifungal solution, such as Sandtex Fungicidal Wash
• All dirt, grease and dusty or powdery residues need to be removed by washing the area with a suitable detergent
• Surface flaws, such as cracks and small holes or cavities, need to be be plugged and fixed with a suitable filler and then sanded smooth
• Eliminate any residue of dust or fragments of debris with washing and cleaning of the project area by using a suitable detergent, then rinse clean and allow to fully dry
• If staining and bleeding still remains after the preparation then patch prime with Crown Trade PX4 All Purpose Primer to help obscure the blemishes
• Uncoated porous substrates will need the first coat to be diluted by 50% to provide a misting coat

Always produce a test area before the application to judge the suitability of the product. Follow the manufacturer's instructions at all times.

To guarantee the consistency of coverage throughout the application, ensure enough Crown Trade PX4 All Purpose Primer is supplied for the project area.

Avoid applying if the air or surface temperatures are likely to be below 8° or to exceed 80% humidity.

• Blend and stir the paint, ensuring to work through the edges and bottom of the tin to provide an even dispersal of the pigment within the paint
• Application can be performed with either a high quality roller, a good quality brush or spray system
• If being applied via a spray, then refer to the manufacturer's recommendations for the correct dilution ratio
• The normal finishing process requires only 1 full coat of Crown Trade PX4 All Purpose Primer if it is used as a primer, but 2 coats are required if the surface is dark or heavily stained
