Aluminium Silicate Asilit® Application

Wood Blasting

Blasting wooden surfaces with Asilit® is an effective method for removing the surface damaged layers, old paints, stains or impurities deeply embedded in the wood. Aluminum silicate is an environmentally friendly blasting media recommended due to its uniform grain size and ability to remove dirt without damaging the wood fibre structure. This technique is often used to restore furniture, wooden constructions or weathered surfaces such as wooden facades or old doors.

Blasting stone, brick and concrete facades

One of the main advantages of using Asilit® is its ability to clean without causing excessive abrasion, which makes it perfect for the restoration of historic facades or old buildings, where protecting the original texture is essential. In addition, this method is effective in removing pollution marks and dirt accumulated over time, giving the facades a fresh and neat appearance. Being an environmentally friendly, fine-grained abrasive, it allows precise cleaning without damaging the surface of facades, being ideal for sensitive materials such as stone, brick or concrete.

Graffiti removal

Cleaning graffiti from various surfaces with Asilit® is an effective and safe method, appreciated for its ability to remove paints without damaging the underlying material. By blasting, graffiti paint is quickly removed without leaving visible marks or structural damage. One of the main advantages of using aluminium silicate is that it does not require the use of harsh chemicals, reducing risks to the environment and operators, making it ideal for large or textured surfaces where other cleaning methods would be less effective.

User Safety

Aluminium Silicate Asilit® is a safe, ecologic and stable material. It does not need special attention while handled. Wearing personal protection equipment is necessary, as well as avoiding eye contact. Storing this material does not require special conditions. All it needs is a good air ventilation in the storage space.

In case of inhalation, the affected person must be taken out, to fresh air, and kept in a comfortable position so he/she can breathe properly. If he/she has difficulties breathing, oxygen can be administered. If he/she stops breathing, CPR manoeuvres can be performed. In this case, a medical intervention is also necessary.

Avoid direct contact with the skin. If your skin entered in direct contact with this abrasive material, you must wash the affected area with clean water for 20 minutes. Use a soft soap and clean water.

In case of ingestion, a doctor’s intervention is necessary. All treatments applied to the victim must take into account the symptoms showed by that victim.

Avoid walking through the material and always wear personal protective equipment. In case of leakages, one must insulate the area on an approximately 25 meters radius in all directions. It is forbidden to spill this material in water. Please avoid dust. Use professional vacuum cleaners to clean the area.

This material comprises silicate crystals and/or quartz. According to the IARC Monographs for assessing the hazards posed by chemical substances to people, this material bears a potential risk of cancer.
