How to change deck stain colour?

[REN138]

If I have just stained my deck with Cabot's water-based Aquadeck stain today, and the color is not what I wanted after it was dry. Can I change it? If so, when is the best time to change it (fully dry, within 24hrs, straight away, etc, etc)? What products and processes shall I use to change it? It is the burnt walnut color??

Hello @REN138 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your deck stain.

If I recall correctly its 8 hours before you can walk on it and 7 days for full cure. Please note that mixing stains with existing stains on your deck is not advised. If you are planning to re-stain the surface of your deck with a different colour, I recommend sanding the current stain off your deck before applying the new stain.

If you have any other questions we can help with, please let us know.

HI,

I don't plan on changing the stain too much. I want the same stain brand, but I think it just wasn't applied properly, and it looks darker in some places and lighter in others. Can I get the stain to look more even? I would even keep the same colour if it didn't look too patchy. He followed the directions but I just think it wasn't applied evenly.

Hello @REN138 

There are a number of reasons why the stain might go on unevenly.

• Insufficient sanding: If the wood wasn't sanded properly or if there are rough spots or cracks, the stain will be absorbed at different rates, leading to patchy results.
  
  
• Staining too quickly: Water-based stains can dry quickly and leave "lap marks" where one area of application overlaps another.
  
  
• Applying too much stain: Applying a thick coat can lead to a sticky, uneven finish and poor absorption.
  
  
• Over-applying: Not wiping off excess stain can cause dark blotches, especially on areas that have absorbed the maximum amount of product.
  
  
• Poor mixing: The pigment in the stain may have settled, resulting in uneven colour if the can wasn't thoroughly stirred or if different cans weren't intermixed.
  
  
• Direct sunlight: Staining in direct sun can cause the stain to dry too quickly, leading to lap marks and an inconsistent finish.

I propose trying to sand down the dark areas of the deck to even out the stain. On your second attempt I suggest staining the surface uniformly without overlapping the sections you've already stained. I recommend using a Cabot's Decking Oil Applicator to assist in spreading the stain evenly.
