Primer after lamination. Provides a better waterproofing, finishing and chemical resistant layer, also filling and primer for Topcoat LT 40 SB. With a maximum water temperature of 30°C. Can be coloured by adding 10-20% UP pigment. Can be sprayed with 5% styrene or acetone.


Mix the T 40 BT with 2-3% Mekp hardener and possibly an additional 1% cobalt accelerator when mixing colour pigments, as these can have a delaying effect (never mix cobalt directly with Mekp hardener, but mix it into the resin separately). Apply with brush or roller. Brush out as thick as possible. Stays slightly sticky to the surface, for better adhesion with the topcoat LT 40 SB. May be applied in two layers.Pot life: approx. 20 min. at 20°C. Processing temperature: 18-25°C. Always apply small quantities in proportion to the potlife.Tip 1: must cure for 7 days at 20°C, then fill with water.Tip 2: all polyesters can be slowed down with inhibitor.Tip 3: use a different color between the T40BT (precoat) and LT40SB (topcoat). This gives better visual control.Tip 4: if T40BT (precoat) comes into contact with water, it turns white). The quantities in grams below are the same as in ml.
