I've painted my counter tops 2 coats of Dulux Renovations Range -Domino. Im about the go to the Dulux Satin Top Coat varnish for renovation range however im seeing some bad reviews for this product stating that it wastes job and leaves streaks / marks. Has anyone used the clear top coat how long should I leave countertop to cure before applying top coat varnish or are there better spray products to use that won’t leave roller marks
Welcome to the Bunnings Workshop community @Lorraine1. It's great to have you join us and many thanks for your questions.
You'll find streaks and marks in the topcoat varnish occur for a few reasons. A new roller needs to be used for the varnish. An adequate amount of product needs to be loaded onto the roller. The varnish is then applied in a single coat and can not be re-worked with the roller once it has been laid. The product is self-levelling and if you try to add more or go over the area once the coating has started to cure this is when you will start to see streaking.
In summary, load a new roller with plenty of topcoat, apply the topcoat to the bench in even passes with consistent light pressure and then leave it to cure. Do not go back over the area once you have laid a coating on it.
You should wait until the next day after painting the benchtop before applying the clear topcoat. Personally, I'm not aware of any other clear topcoats that would be suitable.

Hello @Kmegan80
I'm sorry, but once the clear coat has been applied and has cured there is no way to remove it without damaging the base coat. Did your clear coat form streaks or runs? Would it be possible for you to post a photo of your progress so far?
I can ask the Dulux technical team if there is a way to remedy the clear coat surface. But they'll need to see the condition of your benchtop.
If you have any other questions we can help with, please let us know.

I'm so sorry to hear you've continued to have this issue @Kmegan80. What type of roller are you using? If you can link me to the exact product, that will help immensely with troubleshooting.
I suspect there could be a few things going on that would introduce bubbles:
- If an incorrect roller, like a foam roller, instead of the 4mm fine-napped roller was used
- If the product was shaken to mix instead of stirring or if it was not mixed with a flat-bladed stirrer
- If the coat was applied over the previous without it being fully cured
- If the humidity was too high, the surface was too hot or the product was applied in direct sunlight
- If areas that have begun to cure have been touched
- If the two parts of the product were mixed more than 10 days ago.
If none of the possible causes I've listed above sounds like the issue, then I'd suggest you speak with the Dulux technical team directly, as this certainly seems like a bit of a complex case. Personally, I've never seen that quantity of bubbles in one of their clearcoats, whether it was applied as per directions or not.
Please let me know if you have any questions.

Hi @Kmegan80,
Thanks for that info.
How long did you leave the colour paint coating before applying the clearcoat? Did you use a flat-bladed stirrer by hand?
