Let ${\left\{E_n\right\}}_{n\ge 0}$ and ${\left\{P_n\right\}}_{n\ge 0}$ be sequences of Perrin and Padovan numbers, respectively. We have found all repdigits that can be written as the sum or product of $E_n$ and $P_m$ in the base $\eta$, where $2\le \eta \le 10$ and $m\le n$. In addition, we have applied the theory of linear forms in logarithms of algebraic numbers and Baker-Davenport reduction method in Diophantine approximation approaches.
