Plastering is a crucial aspect of interior home improvement, offering smooth, durable finishes for walls and ceilings. Whether you’re renovating your home or tackling a new build, understanding the plastering process can help you achieve professional results. This guide answers commonly asked questions about plastering, from costs and preparation to drying times and surface treatments. Read on to learn everything you need to know about ensuring flawless plastering work.
How Much Will It Cost to Plaster My Room?
The cost of plastering a room varies based on several factors, including the size of the room, the wall condition, the type of plaster used, and labor charges in your area. If additional services like skimming or overboarding are required, expect the cost to increase. Always get multiple quotes from reputable plasterers to ensure fair pricing.
What Is Overboarding?
Overboarding refers to attaching new plasterboard over existing walls or ceilings to create a smooth, even surface without removing the old one. This method saves time and reduces mess, making it a popular choice for renovating old or damaged surfaces. It’s commonly used for ceilings with cracks or unsightly textures like Artex.
Why Are There Small Cracks and Hazes in My New Plastering?
Small cracks, known as ‘hairline cracks,’ often occur due to rapid drying, incorrect plaster mixing, or uneven application. Hazes or blotchy patches can result from insufficient troweling during the finishing stage. Ensuring a skilled plasterer applies the right technique and allowing adequate drying time can prevent these issues.
How Long Does It Take for Plastering to Dry?
Typically, plaster takes 3-7 days to dry under normal conditions, though thicker applications may require up to 2-3 weeks. Factors like room temperature, humidity levels, and ventilation significantly influence drying time. Avoid painting or applying wallpaper until the plaster is fully dry to ensure a lasting finish.
What Is Skimming?
Skimming is the process of applying a thin layer of plaster over an existing wall or ceiling to create a smooth, flawless finish ready for painting or wallpapering. It’s ideal for covering minor imperfections like cracks, uneven surfaces, and old paint jobs. Skimming requires skilled hands to achieve a professional finish.
What Is Dry Lining?
Dry lining involves fixing plasterboard directly onto walls or ceilings using adhesive or screws, skipping traditional wet plastering. This method is faster, cleaner, and commonly used in modern construction and renovations. Dry lining also improves insulation and soundproofing.
What Do I Need to Prepare for You to Plaster My Room?
To prepare your room for plastering:
- Clear furniture and personal items.
- Remove wall fixtures like shelves, switches, and curtains.
- Protect remaining surfaces with dust sheets.
- Ensure power outlets are safe and accessible.
- Provide clear access to water and electricity if needed.
How Can I Tell If My Plaster Is Dry?
Dry plaster changes from a dark brown or pinkish color to a lighter, consistent shade. It should feel cool but not damp when touched. Use proper lighting to spot any lingering dark patches, indicating incomplete drying.
Will the Plastering Dry More Quickly If I Put the Central Heating on High?
No, turning central heating on high can cause the plaster to dry unevenly, leading to cracks. Instead, maintain moderate room temperature and ensure good ventilation by opening windows. Using a dehumidifier after the initial drying phase can also help.
How Soon Can I Paint My Newly Skimmed Walls?
You should wait at least 5-7 days or until the plaster has completely dried before painting. Apply a mist coat (a mix of water and emulsion paint) as a base layer to prevent peeling. Avoid using vinyl-based paints initially, as they can trap moisture.
Will You Protect My Flooring and Woodwork from Getting Ruined by Plaster?
Professional plasterers typically cover floors, skirting boards, and woodwork with protective sheets or plastic coverings to prevent damage. Confirm this service before hiring, or provide your own protective materials if needed.
Can You Plaster Over Artexing?
Yes, plastering over Artex is possible but requires preparation. High points on the textured surface must be scraped down, followed by applying a bonding agent for better adhesion. Skimming is then done to achieve a smooth, even finish.
How Long Will It Take for You to Plaster a Room?
Plastering a standard-sized room typically takes 1-2 days, depending on the number of walls, surface conditions, and the level of preparation needed. Larger or more complex projects may take longer, so it’s best to discuss timelines during the initial consultation.
Do You Offer Painting and Decorating Services?
Many plastering professionals also offer painting and decorating services as part of a complete home improvement package. This service includes painting, wallpapering, and even tiling. Be sure to ask if these options are available to simplify your renovation process.
Can You Skim Over My Lath and Plaster Ceiling?
Yes, skimming over a lath and plaster ceiling is possible if the ceiling is stable and not showing signs of sagging. If the structure is compromised, overboarding or replacing the ceiling might be a safer option.
Do You Plaster Ceilings?
Yes, professional plasterers often plaster ceilings to create smooth, seamless finishes. This service includes skimming, overboarding, and even repairing damaged sections. A well-plastered ceiling enhances the overall look of your interior and prepares it for painting or decorating.
By understanding these plastering essentials, you can better plan your home renovation or repair project. Always consult experienced plasterers to ensure high-quality results and long-lasting finishes.
