The methods are: cleaning, spreading blankets and anti-slip agents. 1, Cleaning: Because of the hotel, there will inevitably be a lot of oil stains on the floor, which will make the floor slippery and need more daily cleaning effects and times. Putting detergent in hot water to actually wash the mop can effectively wipe off the stains on the floor, and then dry the floor. 2. Carpet laying: If it is not clean or slippery, you can choose to lay a blanket to achieve a good anti-slip effect. Choosing a darker blanket can also have a good effect. 3. Anti-skid agent: If the blanket is not easy to clean, you can also choose to use anti-skid agent to achieve the same effect. Anti-skid agent can effectively penetrate into the pores of floor tiles, greatly reducing the probability of falling. The floor tile with waterproof agent also has anti-slip effect when it is dry.
