Tiling in wet rooms

CITB has developed this standard in discussion with industry

Duration

Minimum 1 day of 6 learning hours per day

Purpose / scope

The purpose of this standard is to provide the candidate with the knowledge and skills to select and install tiling in wet rooms such as: bathrooms, kitchens, toilets, laundries, steam rooms, and swimming pool areas. The scope of this standard covers:

• design considerations including: safety, disability, plumbing, drainage, substrates, backgrounds, bases, ventilation, and tiling
•  how to install waterproofing systems and backgrounds including: liquid applied membranes (single, two-part), flexible sheet systems, rigid tile backer board (with/without built-in waterproofing), background surface preparation prior to waterproofing (walls and floors), and background waterproofing (walls and floors)
• how to select suitable materials including: wall and floor coverings (mosaics, glass, stone), adhesive, grout, sealant, and underfloor heating systems
• how to install tanking systems including: liquid applied membranes (single, two-part), flexible sheet systems (rigid tile backer board with/without built-in waterproofing), for walls and floors
• tile fixing considerations
• how to clean and maintain tiles
• installation issues and solutions
• how to work safely
• related legislation, codes of practice, and standards

Occupational relevance

Training delivered against this standard is relevant to the following occupational group(s):

• operative and craft
• supervision.

Candidate prerequisites

There are no candidate pre-requisites as part of this standard. However, a basic knowledge of tiling terminology and techniques would be beneficial.

Instruction / supervision

As a minimum, course instructors must be able to demonstrate that, in relation to this standard, they have:

• A train the trainer or instructional techniques course certificate
• Successfully completed training to this standard 
• At least 2 years relevant industrial experience
• A verifiable CV.

Delivery

The following method(s) may be used in the delivery of this standard:

• classroom and workshop
• on site in a safe and supervised environment

All materials and equipment must be of a suitable quality and quantity for candidates to achieve learning outcomes and must comply with relevant legislation.

The class size and candidate/instructor ratio must allow training to be delivered in a safe manner and enable candidates to achieve the learning outcomes.

This standard is considered to contain 51 per cent or more practical training.

Assessment

For the successful completion of training, candidates must complete an end of course practical assessment or knowledge test that measures the learning outcomes and has a pass or fail criteria.

Quality assurance

Quality assurance against this standard will require initial approval of the training organisation and their content mapped to the standard. 

CITB will also conduct an approval intervention, either desk-based or centre visit, to ensure the training organisation can meet the requirements of the Training Standard. 

Approved training organisations (ATOs) will be required to present information on records of training and assessment upon request to CITB for desk-based analysis. They will also be visited annually by the CITB quality assurance team.

Renewal/refresher

There are no mandatory renewal or recommended refreshment requirements for this standard.

Approval date

November 2018

Review cycle

Either on request or in 3 years from approval date.
