PBF Process

A Structured Approach That Delivers a Consistent Finish

The quality of GIB stopping comes down to how the work is carried out. A consistent finish is not achieved by rushing through stages or trying to correct issues at the end. It comes from following a clear process from the start, with each stage completed properly before moving to the next.

PBF Gib Stoppers follow a structured approach across all projects, whether it’s a new build, renovation, or commercial job. The focus is on controlling the surface early, managing each stage of the work, and delivering a result that is clean, even, and ready for paint without rework.

1. Initial Assessment and Planning

Understanding the Job Before Work Begins
Every project starts with a proper assessment. This is where the condition of the plasterboard, the type of project, and the required level of finish are reviewed.

No two jobs are the same. New builds, renovations, and repairs all present different challenges, and the approach needs to reflect that from the beginning.

During this stage, key areas are identified:

• Overall condition of plasterboard fixing
• Alignment of walls and ceilings
• Areas that may require correction before stopping
• Level of finish required (Level 4 or Level 5)
• Access, sequencing, and timing within the build

Getting this right at the start ensures there are no surprises later and allows the work to be carried out efficiently.

2. Surface Preparation

Setting Up the Surface for a Proper Finish
Preparation is one of the most important stages in the process. If the surface is not ready, the stopping will not perform as it should.

This stage involves checking that all plasterboard is fixed correctly and addressing any issues before stopping begins. Poor fixing, misaligned sheets, or damaged areas will affect the final result if they are not dealt with early.

Preparation includes:

• Checking all plasterboard sheets are secure and aligned
• Fixing or correcting any loose or uneven areas
• Cleaning surfaces to ensure proper adhesion
• Preparing joints, corners, and edges for stopping

Taking the time to prepare properly allows the rest of the process to run smoothly and reduces the need for correction later.

3. Base Coating and Joint Reinforcement

Building Strength Into the Surface

Once preparation is complete, the first stage of stopping begins. This involves applying base coats to joints and reinforcing them so they can handle movement over time.

Joints are one of the most vulnerable areas in plasterboard. If they are not treated properly, they can crack or become visible once painted.

At this stage:

• Joints are reinforced using high-quality tape systems
• Base compounds are applied to create a strong foundation
• Internal and external angles are set to maintain clean lines
• Fixings are covered to bring them level with the surface

This stage is not about appearance. It is about building strength into the surface so the finish holds over time.

4. Building the Surface

Creating a Flat, Even Finish

After the base coat has been applied and allowed to dry, additional layers are built up to bring the surface to level. This is where the finish starts to take shape.

Each coat is applied with control, ensuring compounds are spread evenly and blended out properly. The goal is to remove any variation between joints and the plasterboard surface.

Key points during this stage:

• Compounds are applied in layers to build up the surface
• Edges are feathered out to avoid visible transitions
• Surfaces are checked regularly for consistency
• Each coat is allowed to dry before the next is applied

This stage requires patience and attention to detail. Rushing it will lead to defects that show later.

5. Skim Coating (Where Required)

Achieving a Higher Level of Finish

For projects requiring a Level 5 finish, an additional skim coat is applied across the entire surface. This creates a uniform finish across all areas, removing minor variations that may be visible under strong lighting.

This step is not required for all jobs, but where it is specified, it plays a key role in achieving a higher standard of finish.

During skim coating:

• A thin, even layer is applied across walls and ceilings
• The surface is controlled to maintain consistency across large areas
• Edges and transitions are refined to ensure a seamless finish

This stage adds time to the process but delivers a more uniform result where required.

6. Sanding and Surface Refinement

Bringing the Surface to Final Level

Once all coats have been applied and dried, the surface is sanded to bring it to its final level. This is where the finish is refined and prepared for painting.

Sanding is carried out carefully to avoid overworking the surface while still removing any minor imperfections.

At this stage:

• Surfaces are sanded to achieve a smooth, even finish
• Edges, corners, and transitions are refined
• The entire area is checked for consistency

This step is critical in ensuring the final surface looks clean once painted.

7. Light Checks and Quality Control

Identifying Issues Before Painting

One of the most important parts of the process is checking the surface under light. This reveals imperfections that may not be visible under normal conditions.

Light checks are carried out throughout the process, but especially after sanding, to ensure the finish is consistent.

This involves:

• Viewing surfaces under different lighting angles
• Identifying any lines, marks, or uneven areas
• Making corrections where required

By carrying out these checks, issues can be addressed before painting, avoiding problems later.

8. Final Inspection

Ensuring the Surface Is Ready for Paint

Before the job is completed, a final inspection is carried out to confirm the surface meets the required standard.

This includes checking:

• Overall consistency across walls and ceilings
• Clean lines and sharp angles
• Evenness of the surface under light
• Readiness for painting without further correction

Only once these checks are complete is the surface considered ready for the next stage.

A Process That Delivers Reliable Results

Following a structured process is what ensures a consistent result across every project. Each stage plays a role in achieving a clean finish, and skipping steps or rushing the work will affect the final outcome.

PBF Gib Stoppers carry out each stage with a clear focus on quality, ensuring plasterboard stopping is completed to a high standard. The result is a surface that is straight, smooth, and ready for paint, without defects showing through once the job is complete.

This approach is applied across all work, providing a reliable finish that holds its quality over time.
