Explanation:

Tenses are used to denote the time when an event occurred. When verbs are modified in such away so as to indicate time, they are called tenses. the tenses can be classified as: -

1.The past tense is used to describe things that have already happened

2.The present tense is used to describe things that are happening right now,

3.The future tense describes things that have yet to happen.

Further, with each of these tenses, there are four aspects associated with it. an aspect here refers to the nature of action performed by the verb. These are: -

1. Perfect

2.Perfect continuous

3.Continuous

4. Simple

In the given sentence, the present perfect tense shall be used. the sentence is completed to: -

 Don't sit on this bench ,I have painted it.

Present perfect tense is used  to  denote an action or state that either occurred at an indefinite time in the past or began in the past and continued to the present time. Here the bench was painted in the past but might still have fresh paint so that one can't sit on it, so present perfect tense is used.
