What is the best product to use and best way to match the texture of this unique interior render?

[alagogold]

I am working on renovating a 1930's home that has a double brick exterior and single brick interior walls throughout the front half of the house.  There are both interior and exterior render points that need to be patched (but I'm starting with the interior seen here) after we've had reclaimed timber windows installed (improved with double glazing) replacing some aluminium frames that were put in the 1960s/70s, brining some of the original character back to the home.  

I have more of a 'flat" render' that I'm less concerned with given the previous posts here on how to fill in render on brick walls.  However, with the unique render style (no idea what it's called) throughout most of the house I need to know how to re-create this pattern or design.  Thank you tremendously for your advice. Advice to match texture that is blue

Welcome to the Bunnings Workshop community @alagogold. It's sensational to have you join us, and many thanks for your question about texturing render.

To repair and match the unique textured render, start by selecting a suitable repair product such as Dunlop 20kg Multipurpose Acrylic Render. This type of product will adhere well and accommodate any slight movement in the wall. Begin by filling in any deeper gaps with the compound, using a trowel or putty knife to smooth it out and make it level with the surrounding render. Once the base layer has dried, you can start working on recreating the texture.

The texture you're aiming to match appears to be more of a splatter effect, where render has been thrown onto the wall and then lightly smoothed. To mimic this, you can use a technique involving a trowel or putty knife to throw the compound at the wall in small amounts, allowing it to splatter naturally. Then, smooth the splattered render slightly using a dry trowel or brush, just enough to create a cohesive texture that blends with the existing pattern. Adjust the size and intensity of the splatter based on the surrounding wall, ensuring a consistent and even coverage. Once the texture is achieved, let the patch dry completely, and then paint over it to match the rest of the wall.

Let the patch dry completely before deciding if any further adjustments are needed. Once the texture matches, you can paint over it to blend seamlessly with the rest of the wall.

Please let me know if you have any questions.
