how long to leave fresh plaster before decorating?

Hi Dickie, You can paint / wallpaper new plaster when it has fully dried, how you can tell that the plaster is dry it will turn a light pink colour. please view this picture of dried plaster.http://www.makeoverbuilders.co.uk/wp-content/uploads/2013/01/plastering4-924x598.jpg Once the plaster has dried if you are going to paint the walls you need to apply a mist coat which is 10-20 % water 90-80 % matt emulsion. stir thoroughly to mix the paint and water. If you are wallpapering then you need to size the walls using size which can be found in the wallpapering adhesive section and simply follow the instructions how to mix depending on how quick the size dries I would recommend applying 2 x coats of size to newly plastered walls. I hope this helps you. Regards Craig.

Achieving a Beautiful Finish: Essential Steps for Painting or Wallpapering New Plaster Preparing new plaster for painting or wallpapering requires meticulous attention to ensure a flawless and long-lasting finish. Here's a comprehensive guide covering both approaches: 1. Thorough Drying: This is crucial! Wait until the plaster reaches a uniform light pink shade or appears fully cured according to the manufacturer's specifications. Patience is key here, as premature application can compromise adhesion and durability. 2. Mist Sealing: Once dry, apply a mist coat ( watered down minimum 50% matt paint, it must not contain any vinyl or a sealer by Zinsser for example, being mindful of visible brush marks.) Allow the sealer to dry completely before proceeding. 3. Sanding for a Smooth Canvas: Gently sand the surface with fine-grit sandpaper to remove any imperfections, bumps, or debris acquired during drying. This creates a smooth foundation for painting or wallpapering. Painting Preparation (Optional): For optimal paint adhesion, consider applying a primer compatible with your chosen paint. This step further enhances the final paint finish. If using a Trade paint this is not required in the majority of cases. Wallpapering Preparation: Cross-lining is essential for a level and stable wallpaper installation. Use lining paper (800g or 1000g) and hang it horizontally (not vertically) if possible.if this is not possible then make sure that all the joints are off set. Allow the lining paper to dry completely, ideally for 24 hours, before hanging your chosen wallpaper. Additional Tips: Always consult the manufacturer's instructions for your specific paint, wallpaper, and lining paper for precise drying times and application techniques. Consider seeking professional assistance from a qualified decorator if you have any concerns or require further guidance for a flawless outcome. By following these essential steps, you can prepare your new plaster for a stunning and professional finish, whether you choose the elegance of paint or the vibrant personality of wallpaper. Remember, patience and meticulous attention to detail are key to achieving a result that will grace your space for years to come.

Hi Dickie, Plaster is ready to paint when 100% of it turns a light shade of pink. A specific period of time cannot be applied as drying times rely on many factors i.e. temperature, humidity, light etc. When the plaster is ready to paint ALWAYS apply a Mist Coat. This is made up from approx 50% emulsion (not silk finish) 45% water and a 5% shot of PVA. Mix the Mist Coat thoroughly, a good five minutes, then apply. Watering the paint down allows it to penetrate the plaster, then as it dries it pulls in the surface plaster dust forming a solid base for the first coat. Good luck. Regards James.
