Peter on 2021-05-02 15:49:41 | Question:
Hi is it possible to colour the white to a cream if so what can I use or do you make it in cream thank you Peter |
Answer from Rawlins’ Technical Team:
I'm afraid not, this is only available in white. As it is a primer it needs to be overcoated so wouldn't be seen. | |
Hardy on 2018-12-03 11:55:22 | Question: How much material primer and sealant will I need for a aspestos garage roof that measures six meters x two and a half meters and what would be the cost Thanks |
Answer from Rawlins’ Technical Team: When applying the Aquashield coatings to fibre cement/asbestos corrugated sheet we always recommend 'double priming' with Britannia Aquashield Primer. In this instance a popular finishing coat would be Britannia Aquashield High Build. To apply 2 coats of Britannia Aquashield Primer followed by 1 coat of Britannia Aquashield High Build to 15m² you should require; 2 x 5lt Britannia Aquashield Primer | |
