Respiratory protection

Select for the hazard, never by appearance

Full mask guide

Possible hazards

  • possible respirable crystalline silica
exposure control planp100 if selected

Priority controls

  • Eliminate or reduce dust/vapour at the source before relying on a respirator.
  • Use appropriate wet methods, HEPA capture, local exhaust and isolation.
  • Read the SDS and exact product instructions.

What is not sufficient

  • A mask alone does not replace wet cutting, capture and exposure assessment.

Stop if

  • Stop if a visible dust cloud persists or source control fails.

Final selection depends on contaminant, concentration, SDS, fit and the applicable program. An air-purifying respirator does not supply oxygen.

Yellow phase — complex project

Wet areas, tile and bathing surfaces

Yellow describes technical complexity, not legal permission. Verify permits, inspections and trade requirements in your province, territory and municipality before starting.

Important limit

This guide helps prepare and oversee the project. Required plans, permits, inspections, manufacturer instructions and professionals prevail.

Understand the system

Layers and interfaces to watch

  1. 1

    Rigid structure and substrate

  2. 2

    Defined slopes and drainage

  3. 3

    Continuous waterproofing with compatible transitions

  4. 4

    Compatible mortar, adhesive and finish

  5. 5

    Movement joints, sealant and access

Homeowner can always

  • Measure, photograph, inventory and document existing conditions.
  • Compare products, unit prices, quantities, rentals and delivery or disposal charges.
  • Verify permits, licences, insurance, references and schedule before signing.
  • Protect belongings, prepare access and keep a daily work log.
  • Observe inspection points without modifying or commissioning a regulated system.

Competent DIY if allowed

  • Perform only non-regulated tasks you understand and that the local authority permits homeowners to do.
  • Follow manufacturer sequence, products and limits without improvising substitutions.
  • Complete a limited test before treating the entire surface or system.
  • Stop before concealing any interface that has not been photographed, tested or inspected.

Qualified trade, permit or inspection

  • Structural design, load sizing and modification of load-bearing elements.
  • Electrical, gas, combustion, refrigerant or regulated connections where required.
  • Permitted or inspected work reserved by the jurisdiction for a contractor or qualified trade.
  • Assessment and remediation of hazardous materials, extensive contamination or structural damage.
  • Plumbing relocation, structure, complete shower or inspected waterproofing.

2
Execution

Verify substrate stiffness, flatness and compatibility with the tile system

Questions for the contractor

  1. What exact method do you propose for “Tile a backsplash” and why does it suit existing conditions?
  2. Which products, models, thicknesses, quantities and accessories are included?
  3. Who obtains permits, schedules inspections and provides reports?
  4. Which concealed conditions would trigger a change and how will it be priced?
  5. Which work will be concealed and when can I photograph or inspect it?
  6. Which tests and measurements will be delivered at acceptance?
