Question:
Is a primer required with Enviroline coatings?
Answer:
For steel, a primer may be required
to hold a prepared surface. If the steel is topcoated immediately
after blasting to a Near White or White Metal finish and before
any rusting occurs, then a primer is not required. If topcoating
is not possible immediately after surface preparation, then
a primer will be required to prevent the degradation of the
prepared surface. After surface preparation, concrete substrates
must usually be sealed with a concrete sealer before the topcoat
is applied. This prevents coating delamination from sub-concrete
water pressure. Enviroline offers a full line of sealers and
primers as well as caulking materials to repair cracked or
damaged surfaces. Check sealer and primer data sheets for
minimum and maximum recoat windows.
Question:
Can standard airless spray equipment be used
to apply Enviroline coatings and linings?
Answer:
Yes, standard airless spray
equipment may be used for most products and usually requires
pre-heating prior to mixing for ease of application. Check
detailed product information prior to use. Hoses should be
1/2" ID minimum ending with a 10 ft. 3/8" whip hose.
A reversible tip (.035) is suggested. Pressure at the pump
should be 90-100 psi, or the maximum recommended by the equipment
manufacturer. Plural component equipment may also be used
and requires volumetric check of the mix ratio.
