Limegreen Stipple coat is a lime-based preparation coat with excellent adhesion, particularly suited to difficult historic structures. Stipple coat is suitable for both high and low-suction masonry backgrounds, providing extra adhesion for subsequent coats of Lime Green Plaster products.
If internal or external masonry walls are very smooth or highly porous, a standard lime base coat may not adhere well to the surface. Lime Green Stipple coat will prepare the substrate for a lime plaster or lime render application.
Walls and ceilings can then be completed with a finish lime plaster such as Lime Green Ultra or Limegreen Duro,
Stipple Coat lime preparation is a lime-based product that allows walls to breathe and expel any trapped moisture. For non-porous sealed surfaces, such as tanking slurries, use Lime Green Grippa.
Stipple Coat can be hand-applied or machine-sprayed for faster coverage.
Coverage
- Approximately 1.7kg per mm of thickness over 1m².
- One 25kg bag will cover approximately 3m² at 4 to 5mm thick.
- This does not include any allowance for wastage.
Surface Preparation
- Remove dust, surface contaminants and loose or friable existing render/plaster.
- Consolidate where necessary.
- Do not apply PVC or other waterproof elements, and do not apply to a painted wall (ensure downspouts are not leaking onto the substrate).
Mixing
- One 25kg sack will need approximately 4 to 5 litres of clean water.
- Mixing should be carried out in a drum or a forced action mixer.
- When using a mixer, mix for 10 minutes; if using a mechanical whisk, mix for 2 to 3 minutes, then stand for 10 minutes, and mix once more before application.
- Use within 30 minutes; do not re-work the mix.
Application
- Always carry out a trial to ensure compatibility.
- Make sure you cover up the surrounding area.
- There are several application methods: Thrown, troweled, and sprayed on with a hopper gun.
- Make sure you apply around 5mm in thickness, leaving the surface rough.
- The finished appearance should resemble ‘roughcast’.
Apply either Lime Green Ultra or Duro as undercoats to build out and level. Lime Green Natural Finish or Solo can be used as finish coats once the backing coats have had sufficient time to cure: generally 3 days, depending on conditions.
Curing
Preventing drying out too quickly is key to the success of the application.
Lightly spray the base coat if it is too hot or drying out too quickly.
In addition, protect from harsh weather conditions, such as frost, rain, and direct sunlight. The use of damp hessian, fixed to the wall, can slow the drying process and provide protection against adverse weather conditions.
