Applying the first scratch jacket. Employ a narrow amount all over the wall. When applying the coat make sure to actually push it into the wall and there are not any spots where the coating is thinner than the remainder. Be sure that you cover the wall as evenly as possible.
After employing the scratch coat all over the wall, then scratch the wall in an even vertical design using a scarifier or scrape tools, which resembles a comb. You may also create your own by making a brush-shaped tool with pieces of wood and screws or nails. After scratching the wall, let the coat adhere to the wall before applying the last coating.
Applying the Final Coating. Implementing the final coating is merely the same as employing the scratch coat, but this time apply a thicker amount compared to the first, because the scratch nail will probably be scratching off a great amount of the top coating. The perfect depth of the final coating is about 10 mm. Ensure that the coating is pushed into the scratch coating and that the wall is coated evenly with no lumpy places. Let the coating stick to the wall that you won’t leave any belief when you touch it is tender enough to be scraped by your fingernails.
