Is Plastering Done Before Flooring?

When it comes to home improvement and interior building, timing is everything. The difference between a smooth completion and expensive rework is often in the degree to which the various phases of a project are coordinated. When it comes to flooring, many homeowners and renovators wonder if plastering is necessary first. Although the sequence may be unimportant at first look, professionals concur that it has a significant impact on the final product’s quality and the project’s efficiency. 

Here we’ll take a look at the pros and cons of plastering before flooring, as well as the reasons why this order is usually followed. This crucial part of construction can save you time, money, and a lot of hassles, whether you’re doing the remodelling yourself or are supervising professionals.

Is Plastering Done Before Flooring?

Yes, plastering is typically done before flooring. The general sequence of construction and renovation is designed to ensure that any messy work is completed before delicate finishes are installed. Here’s why plastering usually precedes flooring:

  • Protection of Flooring: Plastering can be messy, with plaster dust and wet plaster potentially falling on surfaces. Installing flooring first could lead to damage or staining from plaster materials.
  • Smooth Finishes: Plastering involves smoothing walls and ceilings, often with large tools or scaffolding. If flooring is already installed, there’s a risk of scratching, chipping, or denting it during the plastering process.
  • Flexibility for Installation: By plastering before flooring, you have more freedom to move around without worrying about damaging the floor. This flexibility is especially important when large equipment or scaffolding is required to reach high areas.
  • Even Edges: Plastering before flooring ensures that plaster edges meet the floor cleanly. This creates a seamless transition between the wall and the floor, providing a professional finish.
  • Avoiding Trapped Moisture: Plastering involves a lot of water content. By doing it first, you allow time for the plaster to dry completely before flooring installation. This reduces the risk of trapping moisture under floorboards or tiles, which could lead to warping or other damage.

For these reasons, the traditional sequence for most construction projects is to plaster walls and ceilings, and then proceed with flooring installation. This order helps ensure a high-quality finish and avoids potential damage or additional repair work.

Do You Plaster Down To The Floor?

When plastering, the goal is to create a smooth, even surface on walls and ceilings. However, the exact point to which you plaster depends on several factors, such as the type of flooring, the presence of skirting boards (baseboards), and other finishing details. Here’s a general approach to plastering the floor:

  • Plastering with Skirting Boards: If skirting boards (baseboards) are going to be installed, you generally do not need to plaster the floor. Instead, you can leave a small gap at the bottom of the wall where the skirting board will be installed. This gap can vary, but it’s usually around 1/2 to 1 inch. The skirting board then covers this gap, providing a clean transition from wall to floor.
  • Plastering without Skirting Boards: If you’re not using skirting boards, the plaster typically goes all the way down to meet the floor. This requires careful attention to ensure a neat finish, as there’s no trim to cover imperfections.
  • Flooring Installation Considerations: If flooring is already in place (which is less common), you need to be extra cautious to avoid splattering plaster on it. Protecting the floor with drop cloths or other protective materials is crucial.
  • Plastering Before Flooring Installation: If the flooring hasn’t been installed yet, plastering down to the floor is straightforward since there’s no risk of damaging the flooring. This setup allows for easier plastering and provides a clean base for subsequent flooring installation.

When plastering, the most common approach is to leave room for skirting boards if they are part of the design. If skirting boards aren’t used, plaster down to the floor, ensuring a smooth and even edge. The approach you choose depends on your overall design and construction plans.

When Should Plastering Be Done?

Plastering is a critical step in construction and renovation projects, serving as the foundation for smooth walls and ceilings. The timing of plastering is essential for achieving high-quality results and ensuring efficiency throughout the project. Here are the key considerations for when plastering should be done:

  • After Structural Work Is Complete: Plastering should be done once the primary structural work—such as framing, roofing, and major installations (like windows and doors)—is completed. This ensures that there will be no major disruptions that could damage freshly plastered surfaces.
  • After Electrical and Plumbing Work: Make sure that all rough-in work for electrical wiring, plumbing, and HVAC is finished before plastering. This avoids the need to break into freshly plastered walls to make adjustments or add fixtures.
  • After Insulation and Drywall Installation: If drywall (gypsum board) is used as a base for plastering, ensure it’s installed and secured properly. Similarly, any required insulation should be in place beforehand to avoid future disturbances.
  • Before Interior Finishing: Plastering should occur before other interior finishing tasks, such as painting, flooring installation, and trim work (like skirting boards and crown moulding). This minimizes the risk of plaster dust or splatters damaging finished surfaces.
  • Before Installation of Sensitive Equipment: It’s best to complete plastering before installing sensitive equipment, like kitchen appliances, bathroom fixtures, or entertainment systems, to prevent damage
  • Allow Sufficient Drying Time: Plastering involves moisture, so give it ample time to dry and cure before proceeding with painting or applying other finishes. The drying time depends on the type of plaster used and the environmental conditions (like temperature and humidity). Following this guideline ensures that subsequent work doesn’t trap moisture or cause plaster to crack.

Plastering is typically scheduled after the initial structural and utility work but before the final interior finishes. Proper planning and coordination with other trades are key to ensuring a smooth and efficient plastering process.


Plastering, which will serve as the fundamental layer for walls and ceilings, is an essential step in the process of building and renovation. To guarantee that all of the structural, electrical, and plumbing work is finished in advance, the scheduling of the plastering process needs to be meticulously scheduled. Taking this strategy helps to prevent disturbances or damage to surfaces that have recently been plastered.

It is normally recommended that plastering be completed before the installation of flooring and other interior finishes such as painting, trim work, and anything that could potentially be damaged. This procedure helps safeguard fragile surfaces from plaster dust, dampness, and accidental impacts by ensuring that they are protected. Plastering that is properly scheduled also ensures that there is sufficient time for drying and curing, which helps to prevent problems such as cracking or moisture collection.

By collaborating with other professionals and adhering to the best procedures, you will be able to produce a plastered finish of superior quality that will serve as a smooth canvas for the remainder of your interior design. In the end, a well-planned plastering stage adds to a construction or remodelling project that is seamless and efficient, ensuring that your home or structure will have long-lasting durability and aesthetic appeal.
