Rendering — Safe Work Method Statement
Safe Work Method Statement for cement, acrylic and polymer rendering of masonry and panel walls, including mixing, machine spraying, hand application, texturing and working from scaffold.

Rendering is not High Risk Construction Work in its own right, but external rendering on anything above a single storey usually is, because the renderer works from a scaffold or EWP where a fall of more than 2 metres is possible. Ground-floor walls and internal rendering at low height may not trigger HRCW, in which case a SWMS is not legally required, though the builder will usually still want one.
Falls from scaffold are the biggest serious-injury risk. Renderers often modify scaffold to get closer to the wall, pull boards, remove ties or step off the end onto ladders. Only a licensed scaffolder can alter a scaffold that requires a scaffolding licence (where a person or object could fall more than 4 metres), and scaffold must be inspected before use and after any alteration or severe weather. Plan the scaffold with the scaffolder so the deck is close enough to the wall without removing protection.
Wet cement, lime and render mixes are strongly alkaline and cause cement burns, often noticed only hours later through gloves or boots that have filled with slurry. Mixing dry render, sand and cement from bags releases dust that can contain crystalline silica, and grinding or sanding cured render to fix defects creates far more. Machine spraying adds pressurised hoses: a blocked line can burst or whip, and never open a line under pressure. Mixers and spray pumps also bring rotating parts, electrical leads in wet conditions and hand-arm vibration from paddle mixers.
Manual handling is constant: 20 kg bags, buckets of wet render at shoulder height, and repetitive trowelling. Get materials to the scaffold with a hoist or materials platform rather than carrying them up ladders. Hot weather on a sunny wall raises heat stress risk, so plan early starts and shade, water and rest breaks.
Customise this template with the wall heights and scaffold type, who inspects the scaffold and when, the render system and SDS references, mixing location and dust controls, whether a spray machine will be used and who is trained on it, power supply and RCD arrangements, and your heat management plan.

High Risk Construction Work Types
- •Risk of a person falling more than 2 metres
Risk Assessment
1.Scaffold and access inspection
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Fall from scaffold with missing rails, boards or ties | Catastrophic | Check the scaffold tag shows a current inspection before going up. Guardrails, midrails and toeboards in place on all working decks. Renderers must not remove boards, ties or rails; ask the scaffolder for any change. Re-inspect after alteration or high winds. | Low | Site Supervisor / Scaffolder |
| Fall from ladder used to reach the scaffold or above it | High | Access the scaffold by its stair or internal ladder access only. No ladders or trestles on top of scaffold decks to gain extra height; ask for an extra lift instead. | Low | Renderer |
2.Material handling and loading the scaffold
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Back injury carrying bags and buckets up the scaffold | High | Use a materials hoist, gin wheel (by trained person) or forklift/telehandler to a loading bay. Do not carry bags up ladders. Keep bag stacks on the deck within the scaffold's rated load and spread out. | Moderate | Renderer / Leading Hand |
| Objects falling from the scaffold onto people below | High | Toeboards and mesh or chain-wire on the scaffold. Barricade the area below and keep public out. Keep tools and buckets away from deck edges. | Low | Site Supervisor |
3.Mixing render
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Dust inhalation when emptying bags of render, sand and cement | High | Mix outdoors with your back to the wind, or under extraction. Cut bags low and pour slowly. Wear a P2 respirator while emptying bags. Keep others away from the mixing point. | Moderate | Renderer |
| Entanglement or electric shock from mixer or paddle mixer | High | Mixer guards in place. Switch off and isolate before cleaning or reaching into a drum. Leads tested and tagged and plugged into an RCD. Keep leads out of water and slurry. Hold paddle mixers with both hands and limit continuous use to reduce vibration. | Low | Renderer |
4.Applying render by hand or spray machine
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Cement burns from wet render on skin | High | Long-cuff waterproof gloves and long sleeves. Trousers over boots so slurry cannot run in. Wash skin immediately with clean water after contact and change wet clothing. Report any skin redness. | Low | Renderer |
| Eye injury from splashes and spray | High | Wear sealed goggles or a face shield for spraying and overhead work. Eyewash bottle on site. | Low | Renderer |
| Hose burst or whip from blocked spray line | High | Only trained operators run the spray machine. Check hoses and couplings before each shift. If a line blocks, stop the pump and release pressure before opening any coupling. Never point the gun at anyone. | Low | Renderer |
5.Texturing, sponging and repairs to cured render
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Silica dust from grinding or sanding cured render | High | Avoid dry grinding. Where repairs need grinding, use a shrouded tool with an H-class vacuum and a P2 respirator. Wet the surface before sanding by hand. | Moderate | Renderer |
| Strain from repetitive trowelling and overhead work | Moderate | Set scaffold lifts so work is between waist and shoulder height where possible. Rotate tasks and take short breaks. Use lightweight trowels. | Low | Renderer |
6.Working in heat and sun
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Heat stress on exposed walls in summer | High | Start early on hot days and move to shaded elevations in the afternoon. Cool water available and drunk regularly. Rest breaks in shade. Stop work when conditions are extreme. Watch each other for signs of heat illness. | Moderate | Site Supervisor |
7.Clean-up
| Hazard / Risk | Initial Risk | Control Measures | Residual Risk | Responsibility |
|---|---|---|---|---|
| Cement slurry washed into stormwater | Moderate | Wash tools and mixers into a contained washout area, not drains. Let solids settle and dispose of as building waste. | Low | Renderer |
