what happens if...

... I dont use primer??

The threshold to my built-in wardobe has paint missing where it looks like the previous home-owner has sanded the threshold to accomodate a dropping door, as opposed to just re-hanging the door.
I've now re-hung the door and I'm wondering how to fix the bare patch of missing paint.
After doing a bit of research it appears I should prime the bare wood before applying the satinwood.

But what exactly would happen if I didn't use the primer first? just went ahead and slapped a couple of coats of dulux trade satinwood on instead??

Nothing really, as it's self-undercoating.

 

[Jacko74]

that much I know, but then what would be the benefit of priming???

If I dont, is it going to bubble/ discolour/ flake off???

 

[Jacko74]

ah c'mon!!! all you experts and no-one can help!!

Always prime bare wood... Unless its somewhere you dont see (like an old wardrobe!) or youre about to sell your house

Thanks LJ...... but.... Still no answer as to what happens if I dont??!

If you paint gloss , satin, eggshell etc. straight onto bare wood it may peel off , primer is 'designed' to provide a stable base for topcoats (inc undercoat) it has properties that seal the grain & pores of the wood , topcoats need this otherwise the wood will simply absorb the solvents in the paint - drying the paint to quickly and affecting the quality/durability of finished surface...
..ahem

Straight on with the satinwood then
