Decking To Be Painted

davidanbess

Hi The deck was painted last year using latex and the floor of said was painted given 2cts of b/m oil semi transparent gloss

1/ Now latex has started flaking in places (not a lot mind you)
What would your primer be and also your topcoat

2/ The floor is also flaking a little as you walk out from the doorwall
would I be able to apply exterior latex over the semi transparent

Ps As previously posted I arrived here in the states only last Feb and to be honest getting used to all the various materials is definately harder than I thought, for instance in the UK everything is still pretty much oil for exterior and emulsion (latex) for interior.
Anyway thanking you again in anticipation for your collective and constructive replies.

A little confused, you say the deck was painted with latex, then say the floor had BM semi-trans oil? Could you be a little more specific?

sorry let me explain I painted the uprights and handrails a white exterior latex and the floor a diff colour,thinking it would be more hard wearing I used an oil paint, now since the general consensos here is to use water based paints inside and outside I wandering how to put right my work from last year.

That must be one bright yard on a sunny day. If you can, strip the floor and reapply a coat of semi-solid white stain. You are going to need a strong sodium hydroxide based stripper.

PS: your floor should not be flaking if you used a semi trans oil. You must have overapplied it.

what is a semi transparent gloss ??? you got me stumped 20 yrs brush in hand........ semi transparent contains hardly any solid pigment.....thus you can see the wood grain with a slight color.......

was this tranparent put over a paint ?

I think it glossed because he changed it into a film former by applying a second coat wet on dry.

sorry for the confusion the deck boards were given 2cts of beny/moore
Alkyd semi transparent stain and it is only flaking a little. I just really wanted to change to the water based paint for durability

Going to a water borne stain will not give you greater durability per se. Going to a latex paint is even worse on a horizontal surface. Your vapor transmission rate will be shot to hell and if you think it is peeling now, come back in two years to a total flaking mess. I sugest you strip off what is on there and stay with a semi-trans penetrating oil.

decks are usually a redwood. i've found they will always push a latex paint right off. semi-trans stain is the best way to go.

I agree. We do decking and trellis work here in sunny California where summer heat can be tortuous. The only thing we've been able to get to hold up is the oil based semi-transparents. ONE- coat only, 2 coats gives you shiners that never seem to dry hard. You will definitely need to strip the other stuff off to give a good base.

Redwood is too soft for latex out here.

Sorry for the hard lesson, but kudos for willing to make it right.

Hi just to let you know I gave the boards a light wash with a deck scrubber and touched up the high spots which were mainly the grain with the semi transparent and then I applied a full coat to the entire floor it looks a million dollars.
btw thanks for all the replies

Regards D/B

David, I am not trying to knock you but you put a band-aid over a gunshot wound. It may look good, but go back in 6 months and look at it. (if you didn't strip it)

A semi trans has to penetrate the wood and cure there. Did you apply it over what was on there?
