Health & Safety Recommendations

When handling and applying Wykamol High Impact Plaster Finish, standard labour hygiene practices must be observed. Personal Protective Equipment (PPE), including gloves, goggles, and a dust mask, should be worn at all times to prevent inhalation of airborne particles and to minimise direct contact with the skin and eyes.

The product should only be applied in well-ventilated areas to avoid excessive inhalation of dust. Prolonged exposure to airborne particles should be avoided, and hands should be thoroughly washed after handling the product.

Always refer to the product label and Material Safety Data Sheet (MSDS) for comprehensive safety guidelines. The product should be stored in a cool, dry place, away from direct sunlight, excessive moisture, and sources of ignition. Keep out of reach of children and untrained personnel.

 

 

Surface Preparation

Before application, the substrate must be clean, level, structurally sound, and free from dust, grease, loose materials, or any contaminants that could interfere with adhesion. A scratched finish should have been achieved prior to the curing process to ensure a secure bond.

For application over Wykamol Renovation Plaster, existing gypsum plaster, lime backgrounds, or sand-cement renders, the surface should be primed with a 1:1 mixture of SBR Bonding Agent and water. This primer should be applied evenly with a brush, roller, or spray and left until it becomes tacky, which typically takes between 30 minutes and 2 hours.

When applying High Impact Plaster Finish over plasterboard, Wykamol recommends priming the surface with SBR Latex, mixed 1:1 with water, to enhance adhesion. In cases where the existing plaster is in poor condition, damaged plaster should be removed before priming. If applying to Wykamol Renovation Plaster, ensure it has cured for at least 48 hours before proceeding with the application.

 

 

Mixing

Wykamol High Impact Plaster Finish must be mixed using only clean water, a clean mixing vessel, and a mechanical mixer. The recommended water addition is 8.0 - 9.0 litres per 25kg bag. To mix the product, begin by pouring 8 litres of clean water into a suitable mixing vessel. Using an electric paddle mixer, gradually introduce the powder while mixing at low shear to reduce dust generation.

Once all the powder has been added, increase the mixing speed and continue mixing for 1 to 3 minutes until a uniform, lump-free plaster is achieved. If necessary, a small additional amount of water (up to 1 litre) may be added gradually to fine-tune the consistency. Excessive mechanical mixing must be avoided, as over-mixing beyond 5 minutes can compromise the plaster’s thermal and impact-resistant properties.

 

 

Application Method

High Impact Plaster Finish should be applied in a single coat with a minimum thickness of 2mm and a maximum of 5mm. Applying the product at a thickness below 2mm will compromise its impact-resistant properties. The plaster should be applied using standard plastering techniques, ensuring an even and consistent coverage across the substrate. A stainless steel trowel should be used to smooth the finish, while taking care not to overwork the surface, as this may affect the final texture.

The product must not be applied at temperatures below 5°C and rising, or if temperatures are expected to fall below 5°C within the next 24 hours. Before application, ensure the substrate temperature is not below 5°C. Once applied, the plaster should be allowed to harden sufficiently before levelling with a trowel. This typically occurs within 50 to 80 minutes, depending on ambient conditions.

 

 

Conditions & Limitations

Wykamol High Impact Plaster Finish is designed exclusively for interior applications and should not be used for external rendering. It must not be applied to non-compatible materials or surfaces that have not been adequately prepared.

The product is not intended to be used as a standalone waterproofing solution but rather as a highly durable finishing coat in conjunction with appropriate plastering systems. The surface should not be exposed to excessive moisture before it has fully cured, and it should be protected from direct exposure to extreme drying conditions, such as strong draughts or high heat sources.

 

 

Cleaning

Tools and equipment should be cleaned immediately after use with clean water to prevent the plaster from hardening on tools. Once cured, the plaster can only be removed mechanically. Any spills or splashes should be cleaned up promptly to prevent residue build-up on surfaces.

 

 

Finishing & Decoration

Once Wykamol High Impact Plaster Finish has fully dried, which typically takes 24 hours under normal conditions, it can be decorated. If the plaster has been applied as part of the Wykamol Re-Plastering System following a damp-proof course installation, only breathable paints should be used to maintain moisture control.

If redecoration is planned six months or more after a damp-proof course installation, non-breathable finishes such as wallpaper or standard paints may be applied. Before applying non-breathable coatings, ensure that the moisture content of the plaster and background meets the recommendations of the finish supplier.

If left unpainted, High Impact Plaster Finish provides a natural matte appearance that remains highly durable without additional decoration. When applying a decorative coating, ensure that the surface is completely dry to prevent adhesion issues or surface defects.

 

 

Other Information

For optimal performance, Wykamol High Impact Plaster Finish should be used as part of a fully compatible plastering system. If applied over Wykamol Renovation Plaster, ensure that the underlying substrate has been properly prepared to prevent any issues with adhesion or curing. The product should be stored in a dry environment, and any opened bags should be resealed tightly to prevent contamination from moisture or dust.

A) No, it should not be applied when temperatures are below 5°C or if temperatures are expected to drop below this level within 24 hours. The substrate should also be at least 5°C before application. In cold conditions, drying times may be extended.

 

Q) How should tools and equipment be cleaned after using Wykamol High Impact Plaster Finish?

A) All tools and equipment should be cleaned immediately after use with clean water to prevent the plaster from hardening. Once cured, the plaster can only be removed mechanically (e.g., by sanding or grinding).

 

Q) How should Wykamol High Impact Plaster Finish be stored?

A) It should be stored in a dry, frost-free environment, away from moisture or direct sunlight. Any opened bags should be tightly sealed to prevent contamination. Expired or incorrectly stored product should not be used.
