What is DRY FIX® for?
DRY FIX® is a primer coat of epoxy resin which is absorbed into the substrate creating a
permanent bond between the substrate and DRY FLEX® repair. It is not a wood hardener
and it is important to remove all decayed timber before applying DRY FIX®. Use the matching
DRY FIX® for the DRY FLEX® you are using. (eg DRY FIX® 4 with DRY FLEX® 4)
What are the differences between DRY FLEX® 1, 4, and 16?
The numbers refer to approximate drying times in hours (at 20 degrees).
DRY FLEX® 16 is ideal for larger projects where time is not a factor.
DRY FLEX® 4 is suitable for small and large repairs that need completing within a day.
DRY FLEX® 1 is suitable for fast, small repairs from 5 – 10 mm in depth, for example
emergency response maintenance.
Do you have to remove all the rot?
All decay must be removed prior to application for the system to work properly. The moisture
content of the remaining wood must be below 18%. A Repair Care Wood Condition Meter is
available to check the moisture content.
How soon can you paint the repair?
As soon as the DRY FLEX® is fully cured, it can be sanded and then painted or stained. The
exact curing time of DRY FLEX® depends on the size of repair, application temperature and
humidity and the curing time stated on the products is for guidance only.
Can the resin be painted or stained?
Yes, most paints and stains can be used over DRY FLEX®.
Can you nail or screw the resin?
Yes, you can. We recommend drilling a pilot hole first, in the same way you would with
timber.
Can you use the system in the bad weather?
DRY FLEX® should be applied in dry weather and above freezing point.
Are the products guaranteed?
Yes, our products are guaranteed for 10 years, subject to conditions.
Are the products safe to use?
Epoxy resin products are classified as skin irritants. Avoid skin contact by wearing Nitrile
gloves. When appropriate wear eye protection. Full details are available on the product data
sheets.
Is special training needed?
A range of training options is available. Our short, cost effective training courses show the
easiest ways to use the system and ensure that you get the best performance from it. A
training DVD is also available.
Why is my DRY FLEX® not curing in the time stated on the tube?
The exact curing time depends on the size of repair, application temperature and humidity
and the curing time stated on the tubes is for guidance only.
What size repairs can I do?
DRY FLEX® 1 is suitable for repairs up to 10mm deep. There should always be a minimum depth of 5mm to ensure full flexibility in the cured repair.
Can I apply a fine surface filler over DRY FLEX®?
This should be avoided as these fillers have a limited life and can lift the paint prematurely.
For best results use DRY FLEX® SF, a spot repair product formulated to bond to existing
DRY FLEX and substrates.
Can I use DRY FLEX® on listed or historic buildings?
The DRY FLEX® system has been used extensively on many historic buildings. Please ask
your local conservation officer to contact us if there are any queries.
Can I use DRY FLEX® after its expiry date?
We do not recommend you use any product after its expiry date.
