Good Gully Or You’ll End Up Being A Wally

Paul Rigby on creating gullies with vinyl flooring

WHEN I started out on the great journey of working life I met an old experienced tradesman who gave me a small piece advice that has been the mainstay of my standards ever since.

‘Would I accept that in my house?’ He was talking about a lock somebody had fitted into a door, but this same simple sentence can be used as a guideline throughout our industry. I have remembered his words on many occasions when visiting sites for clients unhappy over standards of installations.

For example, in one case there was a combination of vinyl flooring, clamping ring type gullies and clamping channel gullies.

Problems we found have included:

• the vinyl being trimmed around the gully and not dressed into;

• the gully having been inser ted unevenly into the substrate;

• the vinyl cracking around the gully; and

• incorrect adhesive being applied.

Most of these have resulted in water penetration, eventually leading to the failure of the adhesive bond between vinyl and substrate.

In many instances in wet rooms, changing rooms and showers, we have then lifted the floor to find the adhesive in an emulsified condition.

In all the above we can remove the possibility of failure by following simple guidelines. Firstly, if the ring type gully is being used, make sure the gully is the right type for the job and install as per manufacturer’s guidelines.
There is plenty of literature out there supplied by manufacturers for this purpose.

The subfloor must be prepared to meet the requirements and regulations for the installation, and any falls to gullies must not take on the appearance of the bobsleigh run at the Olympics.

The correct adhesive is imperative. You wouldn’t put water in your fuel tank as you know it will end up costing

you money.

So why take a chance with the adhesive? The sheet vinyl flooring must be adhered using a water

resistant adhesive.

Your knife needs to be sharp, with the correct blade. Trim the vinyl, or make use of a template cutter supplied with some ring gullies.

Ensure the vinyl is dressed down into the outlet and the clamping ring is installed as per the

manufacturer’s guidelines.

Weight in the form of bags may need to be applied to the vinyl around the gully to ensure it is fully bonded whilst curing, thus preventing the vinyl lifting.

These are all minor installation processes which, if followed, produce a floor that people walk on and do not notice. If done correctly people do not question the finish. And you can say with confidence ‘I’d accept that in

my house’.
