Work Description

1. Preparation

Hammer test the pebbledash to check for any blown or loose render beneath

2. Masking

Shield doors, windows, paths and surrounding areas with tape and heavy-duty paper, taking great care to protect plants and lawns

3. Restoration and Repair

Remove damaged render from brickwork and open up thermal block cracks to reveal whether any bricks or blocks are cracked

Screw an EML mesh into the brickwork and thermal blocks for reinforcement and to help reduce movement
Apply a two-coat sand and cement render to the damaged areas, then spray Tyrolean render on the walls to create a uniform surface with no visible scarring

4. Bag Rubbing

Brush on a PVA mortar mix called bag rubbing to cover imperfections and act as a base for the next stage

5. Primer Coat

Once the bag rubbing is dry, we work primer into the surface using thick brushes.

6. Final Coat

We use specialist equipment to spray a minimum of 1.2 litres of Andura Classic 21 wall coating on to every square metre. This creates a fantastic even finish guaranteed not to chip, flake, peel or crack for 25 years.

Hatfield

Project Description

A couple in Hatfield, Hertfordshire, needed a company who could change the look of their property and run the project independently.

Brickwork at the front of the property was in two different colours and grades. The lower course had been injected with a damp course treatment, which left the bricks looking unsightly. The customer also asked us to remove the existing mock Tudor fascias to create a whole new look.

Hunstanton

Project Description

The residents of a large block of flats in Hunstanton, Norfolk, had had enough of redecorating their external walls every three years due to the ravages of the salty sea air! They needed a long-term solution.

Click on the section below to read more about the work undertaken on this project.

Work Description

1. Preparation

The high build-up of paint on the exterior walls had an abrasive finish to trap dust and dirt so we use a needle gun to remove it.
Remove large areas of render because damp has seeped in behind
Grind out cracks and fill with an epoxy resin
Use a dryzone damp course treatment on various parts of the properties to help prevent rising damp
Fillet a damp course membrane under the coping stones to help stop render behind the parapets detaching
2. Masking

Mask up windows, doors and drainpipes. This process was carried out in stages to avoid inconveniencing the occupiers any longer than necessary. As most of the flats were holiday homes, we worked on them during the off-peak season.

3. Bag Rubbing

Bag rubbing is vital to help remove scars and imperfections from the walls, as well as stabilise the rendered surface so the next stage (primer) adheres well.

4. Primer Coat

The previous stage has ensured an even finish, so we apply the primer with a roll rather than a brush.

5. Final Coat

Spray Andura Classic 21 on to the wall surface for an amazing end result.

Stocking Pelham

Project Description

This house in Stocking Pelham, Hertfordshire was built in 2005 with a timber frame construction.

Unfortunately some of the mesh attached under the render had come loose, resulting in substantial cracking which needed fixing.

Click on the section below to read more about the work undertaken on this project.

Work Description

1. Preparation

Apply fungicide to front and right elevation of the property, leave overnight to kill spores in the render then wash off

2. Repair

Open up cracks to the render so new mesh can be securely fixed by drilling and fixing screws with washers into timbers
Fill the voids by applying a two-coat render to the open cracked areas

3. Masking

Mask up windows, doors, gutters, down pipes, eaves, brickwork and surrounding areas to protect during the next stage

4. Primer Coat

Apply Andura Classic Primer by brush, leave to dry

5. Final Coat

As the newly repaired cracks are flush and the existing render is reasonably flat, we can use Andura Fine Texture wall coating to complete the job. As you can see, the finish is fantastic.
