Guide to Plaster Coving Application and Fitting: Techniques and Tips
Plaster coving is a decorative and functional element that adds a touch of elegance to any room. Whether you're looking to update your home's interior or simply add some aesthetic appeal, understanding how to properly install plaster coving can make a significant difference. In this article, we will explore the step-by-step process of applying and fitting plaster coving, including various techniques and tips that will ensure a flawless finish.
Understanding Plaster Coving
Plaster coving is a curved or angular molding that is usually installed along the intersection of a ceiling and a wall, or sometimes along the edge of the ceiling. It not only serves a functional purpose but also enhances the overall appearance of a room. Plaster coving can be either preformed and applied with moulding plaster or made in place with a template and a sled that runs on a straight edge guide fastened to the wall.
Step-by-Step Installation Process
The key to a successful installation is precision, attention to detail, and experience. Here's a detailed guide on how to apply and fit plaster coving:
Preparing the Area
Measure and mark the ceiling and walls where the coving will be installed. Ensure that the measurements are accurate as this will make the cutting process easier and more straightforward.
Remove any existing plaster or wallpaper, then sand the edges of the walls where the coving will be mounted to ensure a smooth surface.
Apply painter's tape to the edges of the ceiling and walls to protect them from any splatters or residues during the installation process.
Cutting and Preparing the Plaster Coving
If you are using preformed coving, measure the lengths required and cut them to size using a sharp tool such as a saw or a utility knife, making sure to follow the marked lines accurately.
If the coving needs to be fitted around corners or edges, ensure that you make the appropriate mitre cuts to achieve a seamless junction. This typically involves cutting the coving at an angle of 45 degrees for the corners.
Applying Coving Adhesive or Fixing Nails
Apply coving adhesive to the back of the coving strips, either by hand or using a caulking gun. Ensure that the adhesive is evenly distributed to provide a secure bond.
Alternatively, you can use nails or screws to secure the coving in place. Drilling pilot holes and using a pneumatic or manual nail gun can provide a neat and secure fit.
Installing the Coving
Start attaching the coving from the bottom edge and work your way up the wall. Ensure that the coving is level and straight. For a more professional look, use a spirit level to guide you.
Once the bottom edge is securely fixed, continue attaching the coving, overlapping the previous strip by about 1/8 inch. This overlapping ensures a snug fit and helps to conceal any gaps that may form over time.
If you are using a sled, set it up on a straight edge guide that you have fastened to the wall. This will help to maintain the correct angle and ensure a uniform look. Slide the sled along the guide, pressing the coving firmly into place in one motion.
Fill any gaps or cracks with plaster filler and sand down once dry for a smooth finish.
Professional Tips and Tricks
While you can DIY plaster coving, it's often recommended to have it done by an experienced professional for optimal results. Here are some professional tips:
Measure Twice, Cut Once: Accuracy is crucial. Make sure to double-check your measurements before cutting the coving. Even a small mistake can be difficult to correct.
Smooth Surfaces: Ensure that the walls and ceiling are smooth and free from imperfections. Any rough areas can affect the final look of the coving.
Precision Tools: Use quality tools such as a mitre box or a templating sled to achieve precise cuts and angles. This will result in a more professional and flawless finish.
Quality Adhesives: Use reliable and reputable brands of coving adhesives to ensure a strong and secure bond. Avoid using home-based glues as they may not dry properly.
Sand Carefully: Use a fine-grit sandpaper to sand down the coving for a smooth and even finish. This will help to remove any rough edges or imperfections.
Protective Measures: Cover the floors and furniture with drop cloths to protect them from any splatters or residues. This will keep the work area clean and damage-free.
