ELPR170-TB
NAME:
Envirothane 170-TB Tannin Blocking White Primer
DESCRIPTION:
ELPR170-TB Water based primer provides an excellent foundation for any solid colour systems on MDF as either a 1K or 2K product. When using PR170-TB on veneer, solid wood or in a refinish situation it is necessary to use the product as a 2K system by adding ELCAT100 Hardener to improve adhesion and prevent cracking. Based on a urethane resin system, this high-hide primer lays down very flat and provides unsurpassed filling properties especially for MDF, where it does not swell the fibres like other water based products in the market. It offers all the same properties as our ELPR170 with the addtion of a tannin blocking additive.
USES:
This product is designed for interior wood finishing applications such as cabinetry, tables, furniture and millwork.
SANDING:
MDF substrate should be sanded with at least 180 grit (preferably 320 for any routed- out areas) or finer sandpaper prior to applying primer. Sand primer with 320 grit sandpaper or fine sponges. Two coats can be applied same day back-to-back without sanding between and still acheive good adhesion
