I keep replying to threads like this.
I used this stuff :
http://cgi.ebay.com/EPOXY-RESIN-SEA...66914QQcmdZViewItemQQ_trksidZp1742.m153.l1262
I don't know the above company just bought some stuff from them.
This is 2 part EPOXY RESIN for coating wood with fiberglass / cloth.
So how did I do it.
Get a bag of WASHED SAND or sand the size of bb's or smaller.
Get this two part epoxy or something like it. One is Epoxy ... the gallon the 1/2 gallon is activator/hardener.
Get a gallon of mineral spirits / paint thinner (thinning it lets it soak into the wood).
Go buy a paint roller and some SPONGES at the 99 cent store.
Clean the floor make sure no oil or moisture
Take a tablespoon of the epoxy / a teaspoon of the activator mix together apply a test patch onto the wood to get an idea of how it coats. Dilute it with some thinner to get it to soak into wood. This was your "practice" trial.
You can buy epoxy color for a few dollars ... a one ounce tube for $2.00 will color the 1.5 gallons and help it with UV.
So no onto doing it.
A GALLON AND HALF (PLUS A 1/2 GALLON OF THINNER) ALLOWED ME TO COAT THE DECK TWICE AND THE UNDECARRIAGE ONCE FOR A 20 FOOT BY 8 FEET WIDE TRAILER. and have some leftove to do both sides on a 4x6 sled ramp.
For the first application:
Mix quart of epoxy to pint of activator. Add a pint of thinner.
Take roller brush and apply to all wood surfaces. This sticks to anything ... even the axle and metal beams underneath. You want it to soak into the wood !!!! WAIT till it is tacky for second coat ... depends on the amount of activator. DO NOT WAIT FOR IT TO DRY.
After done then do the same mix quart of epoxy pint of activator ... some thinner.
NOW ADD SOME SAND.
Recoat deck with non skid epoxy.
Use the sponge in places the roller brush could not reach.
Be happy / go sledding.
This is the same way they coat a wood hull on a boat ... except the sand ... do the sand for the deck. Some evn use lead shot instead of sand but expensive.
