Master page and page layout in sharepoint2013

Question

Hi all,

i applied a custom master page to my site collection and i also having an html design for a page in the same sitecollection.

so, i create a new pagelayout using this custom html design for page.

after applying the pagelayout to a new page in my sitecollection the pagelayout is applied along with the master page. i want only the pagelayout to be applied for that page. Not with the masterpage content.

Can anyone help me with this??

Expecting good suggestions..

Thanks in advance.
