Of course, quality brand materials will stand the test of time more than economy makes. The material cost to a redecoration job is always the smallest part, say 10% of total cost, so attempting to save money here is a false economy. The leading brand manufactures such as Dulux, Crown, Leyland etc. invest more in research that improve performance of coatings.
Choosing the right materials for the job, eg. Hammerite or Metalshield for metal railings rather than standard gloss- even though you would not see a difference once applied.
Another example of choosing the right materials would be in painting a galvanised finish. A regular metal primer would not adhere long term to a galvanised finish, hence either Mordens solution or a Bin primer would be a better choice.
There are many products on the market that provide longer term protection for external redecorations
Dulux Ultimate wood stains provides 10 year protection, a solvent based product in various colours
Sadolin woodshield provides 8 year protection and is a water based product in various colours
Dulux weathershield all seasons masonry paint provides 15 year protection, is a solvent based product in various colours
Dulux weathershield exterior gloss a 3 part system providing 8 year protection, oil based and various colours
Workmanship
Another very important part of the overall longevity of the redecoration is the workmanship employed to carry out the works. The cheapest quote is not always the best value for money, if for example the contractor wont perform adequate prep work due to a economy price quoted. To find a professional decorator in the U.K. try the Painting and Decorating Association. It is the marque of quality for the painting and decorating industry.
Preparation and sound base
The preparation and base coat is the most important part of the redecoration process. If the existing woodwork coatings have failed and bare wood has become exposed it is important that the wood is dry. Otherwise painting will seal the moisture in the wood and the coatings applied will fail. This is why it is preferable to redecorate joinery in summer / dry climates.
Any failing coatings, blistered or cracked paint should be scraped back using a scraper or scarson blade. From there, as long as the wood is dry you have a choice of primer coat to seal the bare wood so coatings can adhere:
Stained windows- Dulux preservative basecoat
Glossed windows- Dulux primer undercoat
Dulux zinc woodprimer
Dulux preservative basecoat
I’m sure Crown, Leyland and the other leading brands also have their similar primer coatings and preservative base-coats. Do a web search to find them online.
Mastic / chaulk sealant to prevent water ingress
This step can be performed during the preparation phase or at any time after completion. The edge where the window glass meets the beading can be sealed using window sealant or chaulk and this will ensure water can’t soak into the wood and cause wet rot. It is a simple process and very quick to carry out.
After care of windows and joinery
To keep the windows clean will help preserve. If you have a problem with birds fouling on the sills this will eat away at the coatings, try fitting spikes to solve the problem. Keep a check on the woodwork every few months, if just the beading starts to crack you could get someone in to seal the problem areas and postpone the next redecoration further.
Warranty period
Remember to ask for a warranty on the redecoration works. The Painting and decorating Association recommend its members provide a minimum 6 month warranty, many companies offer 12 months. If there are any problems within the time period, use your warranty. The decorating firm will be happy to rectify and keep their customer for the long term.
