Hello there,

Thank you for choosing our theme and writing in.

1) You can remove Add To Cart button by not setting price for your products. If you do not set price for products, if you want to have only catalogue view of products only 

2) Another method, probably better one, is to use this Custom Css code:

ul.products>.product:hover .added_to_cart, ul.products>.product:hover .button{
    display: none;
}
.woocommerce-page .eltd-content a.button, .woocommerce-page .eltd-content a.add_to_cart_button{
    display: none;
}

which will hide Add To Cart button. Please just paste this Custom Css code into Elated Options > General > Custom Css field https://www.screencast.com/t/HZuLEA5u and once the code is applied properly it will look like this https://www.screencast.com/t/nfBBmJUjNE . 

Please let us know if this solved the issue and if there is anything else we can do fro you.

Thanks.
