What is the correct steps to repair this engineered timber floor plank? I noticed that there is kind of like bubbling or creases on the top coating of this engineered timber floor plank. I am not sure what causes it, it was installed less than 2 months ago. It probably was there since the beginning and I only noticed it recently.
I am thinking of sanding the creases off with a sand paper. If there is a space or gap after sanding, I am thinking of applying Timbermate otherwise if no gap I will leave it as is. But what is the next step? Do I have to apply a premier first? If so, which do I use? The original coating of this plank is called Treffert Matt Lacquer (I believe this is a water based coating). However, I cannot find this product at Bunnings. Which is the closest or compatible product I can use? Is it Cabot's Clear CFP Floor Water Based Matt? If wrong product, please advise.
To summarise the steps (please advise if incorrect).
Step 1: Sand with 120 grit (or higher number) sand paper;
Step 2: Apply premier (please advise if this step is necessary and which product? Prefer clear premier if any).
Step 3: Apply Cabot's CFP water based varnish. Does Bunnings have smaller size can? Is Cabot's Matt Water Based Cabothane suitable for this application?
I have attached several pictures of the top coating creases.
Thank you in advance.
