Answer 1

$paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;

And to the query add this:

$query = new WP_Query( array( 'paged' => $paged, 'post_type' => 'catalog', 'meta_key' => 'builder', 'meta_value' => $builder, 'posts_per_page' => $count_n) )

Answer 2

Since, 'paged' parameter is not specified, to get next set of posts. You can use following code,

if ( get_query_var('paged') ) { $paged = get_query_var('paged'); }
elseif ( get_query_var('page') ) { $paged = get_query_var('page'); }
else { $paged = 1; }

$query = new WP_Query( array( 'posts_per_page' => $count_n, 'paged' => $paged, 'post_type' => 'catalog', 'meta_key' => 'builder', 'meta_value' => $builder) );
